The IBM T220 and T221 are LCD monitors with a native resolution of 3840×2400 pixels (WQUXGA) on a screen with a diagonal of 22.2 inch (564 mm). This works out as over 9.2 million pixels, with pixel density of 204 pixels per inch (80 dpcm, 0.1245 mm pixel pitch), much higher than ordinary computer monitors (which typically have about 100 pixels per inch) and approaching the resolution of print media. The display family was nicknamed "Big Bertha" in some trade journals.

The IBM T220 was introduced in June 2001 and was the first monitor to natively support a resolution of 3840×2400.DVI connectors, for a total of four DVI channels. One, two or four of the connectors may be used at once.

IBM T220 comes with a Matrox G200 MMS video card, and two power supplies. To achieve native resolution, the screen is sectioned into four columns of 960×2400 stripes. Under DOS mode, the monitor/card combination only supports 960×1200[citation needed] screen mode running at 56 Hz. The monitor"s native refresh rate is 41 Hz.

This is a revised model of the original T220. Notable improvements include using only one power adapter instead of two, support for more screen modes and driver support for Linux out of the box. However, power consumption increased from 111 to 135 watts (111 to 150 at maximum.) They were initially available as 9503-DG1 and 9503-DG3 models. The 9503-DG1 model came with a Matrox G200 MMS graphics card and two LFH-60 connector cables. The 9503-DG3 model came with a one cable, connecting from a single DVI port on the graphics card to the T221"s special sockets.[citation needed]

The 9503-DG1 model T221 originally ran at maximum resolution in four 960×2400 stripes. Later firmware permitted a 1920×1200 tile mode as well.[citation needed]

IBM T221 started out as an experimental technology from the flat panel display group at IBM Thomas J. Watson Research Center. In 2000, a prototype 22.2" TFTLCD, code-named "Bertha", was made in a joint effort between IBM Research and IBM Japan. This display had a pixel format of 3840×2400 (QUXGA-W) with 204 ppi. On 10 November 2000, IBM announced the shipment of the prototype monitors to U.S. Department of Energy’s Lawrence Livermore National Laboratory in California. Later in 2001-06-27, IBM announced the production version of the monitor, known as T220. Later in November 2001, IBM announced its replacement, IBM T221. On 19 March 2002, IBM announced lowering the price of IBM T221 from US$17,999 to US$8,399. Later in 2 September 2003, IBM announced the availability of the 9503-DG5 model.

IBM and Chi Mei Group of Taiwan formed a joint venture called IDTechViewSoniciiyamaOEMed the T221 and sold it under their brand names. The production line of IDTech at Yasu was sold to Sony in 2005Chi Mei has since demonstrated a 56" 3840×2160 QuadHDTV display.

Toshiba "announced" an exact clone of the IBM T221 in November 2007, but Toshiba did not produce it then, or in the (recession)years that followed. Neither Toshiba nor others on the Internet have offered any explanation.

The QXGA, or Quad eXtended Graphics Array, display standard is a resolution standard in display technology. Their high pixel counts and heavy display hardware requirements mean that there are currently few CRT and LCD monitors which have pixel counts at these levels. These terms are currently relegated to the highest-end consumer computer display hardware for those buying LCD.

WQXGA is often found in 30" displays like the Dell 3008WFP and the Apple Cinema Display. As of this date, there are few WQXGA displays in the consumer marketplace, but their price is higher than most displays used by graphic professionals, and their refresh speed is not close to that used in current consumer displays. It is unlikely that WQXGA, or next-generation HXGA, displays will be commonplace anytime soon. It should also be noted, however, that many standard 21" / 22" CRT monitors can be used at the QXGA resolution. Some of the highest-end 19" CRTs also support this resolution.

QXGA (Quad eXtended Graphics Array) is a display resolution of 2048×1536 pixels with a 4:3 aspect ratio. The name comes from the fact that it has four times as many pixels as an XGA display. As of 2007, this is the highest non-experimental and non-widescreen resolution, and the number of monitors that can display images at this resolution are somewhat limited, especially among LCDs. The number of CRT monitors offering this resolution has actually dropped off, as CRT makers such as NEC and Sony have stopped offering their higher end models. Examples of LCDs with this resolution are the IBM T210 and the Eizo G33 and R31 screens, but in CRT monitors this resolution is much more common; some examples include the ViewSonic G225fB, NEC FP2141SB or Mitsubishi DP2070SB, Iiyama Vision Master Pro 514, and Dell and HP P1230. Of these monitors, none is still in production. A related display size is WQXGA, which is a wide screen version. CRTs offer a way to achieve QXGA cheaply. Models like the Mitsubishi Diamond Pro 2045U and IBM ThinkVision C220P retailed for around 200 USD, and even higher performance ones like the ViewSonic PerfectFlat P220fB remained under 500 USD. As recently as last year, many off-lease P1230s could be found on eBay for under 150 USD. The LCDs with WQXGA or QXGA resolution typically cost 4 to 5 times more for the same resolution. IDTech manufactured a 15" QXGA IPS panel. NEC had sold laptops with QXGA screens in 2002-2005 for Japanese market

Prior to 2007, devices that could display this resolution were very rare, but many manufacturers have since come out with a 27"-30" model that is capable of WQXGA, albeit at a much higher price than lower resolution monitors of the same size. Several mainstream WQXGA monitors are available with 30 inch displays, such as the Apple Cinema Display, the Dell UltraSharp 3007WFP-HC and 3008WFP, the Hewlett-Packard LP3065, the Gateway XHD3000, and the Samsung 305T. Specialist manufacturers like Planar Systems, Barco (LC-3001) and possibly others offer similar models. The 27" iMac and Dell U2711 monitor also feature a 27" S-IPS panel from LG Display which has 2560×1440 resolution.

One feature which is currently unique to the 30" WQXGA monitors are their ability to function as the centerpiece & main display of a three-monitor array of complementary aspect ratios, with two UXGA (1600x1200) 20" monitors turned vertically on either side. The resolutions are equal, and the size of the 1600 resolution edges (if the manufacturer is honest) is within a tenth of an inch, presenting a "picture window view" without the extreme lateral dimensions, small central panel, asymmetry, resolution differences, or dimensional difference of other three-monitor combinations. The resulting 4960x1600 composite image has a 3.1:1 aspect ratio.

Of course, this also means one UXGA 20" monitor in portrait orientation can also be flanked by two 30" WQXGA monitors for a 6320x1600 composite image with a 15.8:3 (79:15, 5.267:1) aspect ratio.

QWXGA (Quad Wide eXtended Graphics Array) is a display resolution of 2048×1152 pixels with a 16:9 aspect ratio. A few LCD QWXGA monitors are available with 23 and 27 inch displays, such as the Acer B233HU (23") and B273HU (27"), the Dell SP2309W, and the Samsung 2342BWX.

QSXGA (Quad Super Extended Graphics Array) is a display resolution of 2560×2048 pixels with a 5:4 aspect ratio. Grayscale monitors with a 2560×2048 resolution, primarily for medical use, are available from Planar Systems (Dome E5), Eizo (Radiforce G51), Barco (Nio 5,MP), WIDE (IF2105MP), IDTech (IAQS80F) and possibly others.

This resolution is exactly four times 1920x1200 (in pixels) and was released as a product in June 2001 by an IBM display panel built into the IBM T220 LCD monitor, IBM T221 (models DG1, DG3, DG4, DG5), Iiyama AQU5611DTBK, ViewSonic VP2290b IDTech MD22292 (models B0, B1, B2, B5, C0, C2; all other brands are in fact relabeled IDTech models, IDTech does not sell these monitorsdisplay cards with a DVI connector are capable of supporting the 3840x2400 resolution. However, the maximum refresh rate will be limited by the number of DVI links that are connected to the monitor. 1, 2, or 4 DVI connectors are used to drive the monitor using various tile configurations. Only the IBM T221-DG5 and IDTech MD22292B5 support the use of dual-link DVI ports using an external converter box.

Most systems using these monitors use at least 2 DVI connectors to send video to the monitor. These DVI connectors can be from the same graphics card, different graphics cards, or even different computers. Motion across the tile boundary(ies) can show tearing if the graphics card(s) are not synchronized. The display panel can be updated at a speed between 0Hz and 41Hz (48Hz for the IBM T221-DG5, and IDTech MD22292B5). The refresh rate of the video signal can be higher than 41Hz, or 48Hz, but the monitor will not update the display any faster if graphics card(s) do so.

As of January 2007, none of the WQUXGA monitors (IBM, ViewSonic, Iiyama, ADTX) are in production anymore. The highest-resolution color displays on sale are WQXGA. However, Eyevis produces a 56" LCD named EYELCD 56 QUAD HD which can deliver 3840x2160

International Display Technology (IDTech) was a partnership between Taiwan"s Chi Mei Corporation and IBM Japan. Its manufacturing factory was sold to Sony in 2005. The headquarters was renamed to the current name, CMO Japan Co., Ltd. in 2006. It manufactured the IBM T220/T221 LCD monitors, among other products.

A number of common resolutions have been used with computers descended from the original IBM PC. Some of these are now supported by other families of personal computers. These are de facto standards, usually originated by one manufacturer and reverse-engineered by others, though the VESA group has co-ordinated the efforts of several leading video display adapter manufacturers. Video standards associated with IBM-PC-descended personal computers are shown in the diagram and table below, alongside those of early Macintosh and other makes for comparison. (From the early 1990s onwards, most manufacturers moved over to PC display standards thanks to widely available and affordable hardware).

unnamedunnamedA common size for LCDs manufactured for small consumer electronics and mobile phones, typically in a 1.7" to 1.9" diagonal size. This LCD is often used in the portrait (128×160) orientation. The unusual 5:4 aspect ratio makes the display slightly different from the QQVGA dimensions.160×128 (20k)5:4

QVGAQuarter Video Graphics ArrayHalf the resolution in each dimension as standard VGA. A retronym for CGA "medium" and EGA/MCGA/VGA "low" pixel resolution, normally used when describing screens on portable devices (pocket media players, cellular phones, PDAs etc.). No set colour depth or refresh rate is associated with this standard or those that follow, as it is dependent both on the manufacturing quality of the screen and the capabilities of the attached display driver hardware, and almost always incorporates an LCD panel with no visible line-scanning. However, it would typically be in the 8-to-12 bpp (256 to 4096 colour) through 18 bpp (262,144 colour) range.320×240 (75k)4:3

ST ColourAtari ST (etc.) Colour, Broadcast-standardAtari ST line. Colour modes using NTSC or PAL-compliant televisions and monochrome, composite video or RGB-component monitors.640×200, 320×2004:3 (or 16:10 with square pixels)2~4 bpp for ST, 8~15 bpp on later models (TT, Falcon).

ST MonoAtari ST (etc.) Monochrome, proprietary standardAtari ST line. Hi-res monochrome mode using a custom non-interlaced monitor, possibly derived from monochrome VGA, with the slightly lower vertical resolution (imposed by limited video memory) allowing a higher, "flicker free" 70 Hz refresh rate. Later machines in the series could also use colour VGA monitors.640×4004:3 (or 16:10 with square pixels)1 bpp for ST, 4~6 bpp greyscale on later models (TT, Falcon), plus 8 bpp colour on VGA monitors.

Video monitor I/NIFull-broadcast resolution video monitor or televisionCommodore Amiga line and others (e.g. Acorn Archimedes, later Atari models (TT, Falcon). They used NTSC or PAL-compliant televisions and monochrome, composite video or RGB-component monitors. The interlaced (I) mode produced visible flickering of finer details, eventually fixable by use of scan doubler devices and VGA monitors.720×480i/576i maximum. Typically 640×400i/512i or 640×200/256 NI, and 320×200/256 NI for games.4:3 (non-square pixels)Up to 6 bpp for Amiga (8 bpp with later models), typically 2~4 bpp for most hi-res applications (saving memory and processing time), 4~5 bpp for games and "fake" 12/18 bpp for static images (HAM mode). Up to 15 bpp for Archimedes and Falcon (12 bpp for TT), but typically 4 bpp in use.

Mac ColourApple Mac II and later modelsThe second generation Macintosh, launched in 1987, came with colour (and greyscale) capability as standard, at two levels depending on monitor size - 512×384 pixel (one-quarter of the later XGA standard) on a 12" (4:3) colour or greyscale ("monochrome") monitor, 640×480 with a larger (13" or 14") high resolution monitor (superficially similar to VGA but at a higher 67 Hz refresh rate) - with 8-bit colour/256 grey shades at the lower resolution, and either 4 or 8 bit colour (16/256 grey) in high resolution depending on installed memory (256 or 512 kB), all out of a full 24-bit master palette. The result was equivalent to VGA or even PGC - but with a wide palette - at a point simultaneous with the IBM launch of VGA.

Later, larger monitors (15" and 16") allowed use of an SVGA-a-like, binary-half-megapixel 832×624 resolution (at 75 Hz) that was eventually used as the default setting for the original, late 90s iMac. Even larger 17" and 19" monitors could attain higher resolutions still, when connected to a suitably capable computer, but apart from the 1152×870 "XGA+" mode discussed further below, Mac resolutions beyond 832×624 tended to fall into line with PC standards, using what were essentially rebadged PC monitors with a different cable connection. Mac models after the II (Power Mac, Quadra, etc.) also allowed at first 16-bit High Colour (65536 or "Thousands of" colours) and then 24-bit True Colour (16.7m or "Millions of" colours), but much like PC standards beyond XGA, the increase in colour depth past 8 bpp was not strictly tied to changing resolution standards.512×384 (197k), 640×480 (307k), 832×624 (519k)4:34 bpp, 8 bpp, and later 16/24 bpp

Powerbook internal panelApple Powerbook, early generationsThe first Powerbook, in 1991, replaced the original Mac Portable (basically an original Mac with an LCD, keyboard and trackball in a lunchbox-style shell) and introduced a new 640×400 greyscale screen. This was joined in 1993 with the "165c" model, which kept the same resolution but added colour capability similar to that of the Mac II (256 colours from a palette of 16.7 million).640×400 (256k)16:10 / 8:5 (square pixels)8 bpp

MDAMonochrome Display AdapterThe original standard on IBM PCs and IBM PC XTs with 4 kB video RAM. Introduced in 1981 by IBM. Supports text mode only.720×350 (text)72:35 (effectively 4:3 (non-square pixels) on CRTs but could be a variety of aspects on LCDs)1 bpp

CGAColor Graphics AdapterIntroduced in 1981 by IBM, as the first color display standard for the IBM PC. The standard CGA graphics cards were equipped with 16 kB video RAM.640×200 (128k)

EGAEnhanced Graphics AdapterIntroduced in 1984 by IBM. A resolution of 640×350 pixels of 16 different colors (4 bits per pixel, or bpp), selectable from a 64-color palette (2 bits per each of red-green-blue).640×350 (224k), 640×200 (128k), 320×200 (64k)64:35, 16:5 and 16:10/8:5 (all effectively 4:3)4 bpp

MCGAMulticolor Graphics AdapterIntroduced by IBM on ISA-based PS/2 models in 1987, with reduced cost compared to VGA. MCGA had a 320×200 256 color (from a 262,144 color palette) mode, and a 640×480 mode only in monochrome due to 64k video memory, compared to the 256k memory of VGA.320×200 (64k)

Video Graphics ArrayIntroduced on MCA-based PS/2 models in 1987. VGA is actually a set of different resolutions, but is most commonly used today to refer to 640×480 pixel displays with 16 colors (4 bits per pixel) and a 4:3 aspect ratio. Other display modes are also defined as VGA, such as 320×200 at 256 colors (8 bits per pixel) and a text mode with 720×400 pixels. VGA displays and adapters are generally capable of Mode X graphics, an undocumented mode to allow increased non-standard resolutions, most commonly 320×240 (with 8 bpp and square pixels).640×480 (307k) (hi-res graphics and LCD text)

SVGASuper Video Graphics ArrayA video display standard created by VESA for IBM PC compatible personal computers. Introduced in 1989. Displayed the regular VGA modes, plus 800×600 in 16 colours at a slightly lower 56 Hz refresh rate.

XGAExtended Graphics ArrayAn IBM display standard introduced in 1990. XGA added built on 8514/A"s existing 1024×768 mode and added support for "high color" (65,536 colour, 16 bpp) at 640×480. The second revision ("XGA-2") was a more thorough upgrade, offering higher refresh rates (75 Hz and up, non-interlaced, up to at least 1024×768), improved performance, and a fully programmable display engine capable of almost any resolution within its physical limits. For example, 1280×1024 (5:4) or 1360×1024 (4:3) in 16 colors at 60 Hz, 1056×400 [14h] Text Mode (132×50 characters), 800×600 in 256 or 64k colour, and even as high as 1600×1200 (at a reduced 50 Hz scan rate) with a high quality multisync monitor (or an otherwise non-standard 960×720 at 60 Hz on a lower-end one capable of high refresh at 800×600, but only interlaced mode at 1024×768).1024×768 (786k)

SXGASuper Extended Graphics ArrayA widely used aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1.33:1), meaning even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution - with, therefore, square pixels - of standard 17" and 19" LCD monitors. It was often a recommended resolution for 17" and 19" CRTs also, although as they were usually produced in a 4:3 aspect it either gave non-square pixels or required adjustment to show small vertical borders at each side of the image. Allows 24-bit colour in 4 MB of graphics memory, or 4-bit in 640 kB.Some manufacturersde facto industry standard was VGA (Video Graphics Array), termed this the Extended Video Graphics Array or XVGA.1280×1024 (1310k)5:424 bpp

Full-HDFull High Definition (1080p)This display aspect ratio is the native resolution for many 24" widescreen LCD monitors, and is expected to also become a standard resolution for smaller to medium-size, wide-aspect tablet computers in the near future (as of 2012).1920×1080 (2073k)16:924 bpp

WUXGAWidescreen Ultra Extended Graphics ArrayA wide version of the UXGA format. This display aspect ratio was popular on high-end 15" and 17" widescreen notebook computers, as well as on many 23–27" widescreen LCD monitors, until ca. 2010. It is also a popular resolution for home cinema projectors, besides 1080p, in order to show non-widescreen material slightly taller than widescreen (and therefore also slightly wider than it might otherwise be), and is the highest resolution supported by single-link DVI at standard colour depth and scan rate (I.E. no less than 24 bpp and 60 Hz non-interlaced)1920×1200 (2304k)16:1024 bpp

QXGAQuad Extended Graphics ArrayThis is the highest resolution that generally can be displayed on analog computer monitors (most CRTs), and the highest resolution that most analogue video cards and other display transmission hardware (cables, switch boxes, signal boosters) are rated for (at 60 Hz refresh). 24-bit colour requires 9 MB of video memory (and transmission bandwidth) for a single frame.

The 4:3 aspect ratio was common in older television cathode ray tube (CRT) displays, which were not easily adaptable to a wider aspect ratio. When good quality alternate technologies (i.e., liquid crystal displays (LCDs) and plasma displays) became more available and less costly, around the year 2000, the common computer displays and entertainment products moved to a wider aspect ratio, first to the 16:10 ratio. The 16:10 ratio allowed some compromise between showing older 4:3 aspect ratio broadcast TV shows, but also allowing better viewing of widescreen movies. However, around the year 2005, home entertainment displays (i.e., TV sets) gradually moved from 16:10 to the 16:9 aspect ratio, for further improvement of viewing widescreen movies. By about 2007, virtually all mass market entertainment displays were 16:9. In 2011, 2073600 !1920 × 1080 (Full HD, the native resolution of Blu-ray) was the favored resolution in the most heavily marketed entertainment market displays. The next standard, 8294400 !3840 × 2160 (4K UHD), was first sold in 2013.

This resolution is equivalent to a Full HD (2073600 !1920 × 1080) extended in width by 33%, with an aspect ratio of 64:27. It is sometimes referred to as "1080p ultrawide" or "UW-FHD" (ultrawide FHD). Monitors at this resolution usually contain built in firmware to divide the screen into two 1382400 !1280 × 1080 screens.

This resolution is equivalent to two Full HD (2073600 !1920 × 1080) displays side-by-side, or one vertical half of a 4K UHD (8294400 !3840 × 2160) display. It has an aspect ratio of 32:9 (3.55:1), close to the 3.6:1 ratio of IMAX UltraWideScreen 3.6. Samsung monitors at this resolution contain built in firmware to divide the screen into two 2073600 !1920 × 1080 screens, or one 2764800 !2560 × 1080 and one 1382400 !1280 × 1080 screen.

The first commercial displays capable of this resolution include an 82-inch LCD TV revealed by Samsung in early 2008,PPI 4K IPS monitor for medical purposes launched by Innolux in November 2010.Toshiba announced the REGZA 55x3,

When support for 4K at 60Hz was added in DisplayPort 1.2, no DisplayPort timing controllers (TCONs) existed which were capable of processing the necessary amount of data from a single video stream. As a result, the first 4K monitors from 2013 and early 2014, such as the Sharp PN-K321, Asus PQ321Q, and Dell UP2414Q and UP3214Q, were addressed internally as two 4147200 !1920 × 2160 monitors side-by-side instead of a single display and made use of DisplayPort"s Multi-Stream Transport (MST) feature to multiplex a separate signal for each half over the connection, splitting the data between two timing controllers.Asus PB287Q no longer rely on MST tiling technique to achieve 4K at 60Hz,

The Quarter Video Graphics Array (also known as Quarter VGA, QVGA, or qVGA) is a popular term for a computer display with 76800 !320 × 240 display resolution that debuted with the CGA Color Graphics Adapter for the original IBM PC. QVGA displays were most often used in mobile phones, personal digital assistants (PDA), and some handheld game consoles. Often the displays are in a "portrait" orientation (i.e., taller than they are wide, as opposed to "landscape") and are referred to as 76800 !240 × 320.

The name comes from having a quarter of the 307200 !640 × 480 maximum resolution of the original IBM VGA display technology, which became a de facto industry standard in the late 1980s. QVGA is not a standard mode offered by the VGA BIOS, even though VGA and compatible chipsets support a QVGA-sized Mode X. The term refers only to the display"s resolution and thus the abbreviated term QVGA or Quarter VGA is more appropriate to use.

Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987.analog computer display standard, the 15-pin D-subminiature VGA connector, or the 307200 !640 × 480 resolution itself. While the VGA resolution was superseded in the personal computer market in the 1990s, it became a popular resolution on mobile devices in the 2000s.307200 !640 × 480 is called Standard Definition (SD), in comparison for instance to HD (921600 !1280 × 720) or Full HD (2073600 !1920 × 1080).

It is a common resolution among LCD projectors and later portable and hand-held internet-enabled devices (such as MID and Netbooks) as it is capable of rendering web sites designed for an 800 wide window in full page-width. Examples of hand-held internet devices, without phone capability, with this resolution include: Spice stellar nhance mi-435, ASUS Eee PC 700 series, Dell XCD35, Nokia 770, N800, and N810.

Originally, it was an extension to the VGA standard first released by IBM in 1987. Unlike VGA – a purely IBM-defined standard – Super VGA was defined by the Video Electronics Standards Association (VESA), an open consortium set up to promote interoperability and define standards. When used as a resolution specification, in contrast to VGA or XGA for example, the term SVGA normally refers to a resolution of 480000 !800 × 600 pixels.

The Extended Graphics Array (XGA) is an IBM display standard introduced in 1990. Later it became the most common appellation of the 786432 !1024 × 768 pixels display resolution, but the official definition is broader than that. It was not a new and improved replacement for Super VGA, but rather became one particular subset of the broad range of capabilities covered under the "Super VGA" umbrella.

The initial version of XGA (and its predecessor, the IBM 8514/A) expanded upon IBM"s older VGA by adding support for four new screen modes (three, for the 8514/A), including one new resolution:

Like the 8514, XGA offered fixed function hardware acceleration to offload processing of 2D drawing tasks. Both adapters allowed offloading of line-draw, bitmap-copy (bitblt), and color-fill operations from the host CPU. XGA"s acceleration was faster than 8514"s, and more comprehensive, supporting more drawing primitives, the VGA-res hi-color mode, versatile "brush" and "mask" modes, system memory addressing functions, and a single simple hardware sprite typically used to providing a low CPU load mouse pointer. It was also capable of wholly independent function, as it incorporated support for all existing VGA functions and modes – the 8514 itself was a simpler add-on adapter that required a separate VGA to be present. As they were designed for use with IBM"s own range of fixed-frequency monitors, neither adapter offered support for 480000 !800 × 600 SVGA modes.

IBM licensed the XGA technology and architecture to certain third party hardware developers, and its characteristic modes (although not necessarily the accelerator functions, nor the MCA data-bus interface) were aped by many others. These accelerators typically did not suffer from the same limitations on available resolutions and refresh rate, and featured other now-standard modes like 480000 !800 × 600 (and 1310720 !1280 × 1024) at various color depths (up to 24 bpp Truecolor) and interlaced, non-interlaced and flicker-free refresh rates even before the release of the XGA-2.

XGA should not be confused with EVGA (Extended Video Graphics Array), a contemporaneous VESA standard that also has 786432 !1024 × 768 pixels. It should also not be confused with the Expanded Graphics Adapter, a peripheral for the IBM 3270 PC which can also be referred to as XGA.

Wide Extended Graphics Array (Wide XGA or WXGA) is a set of non standard resolutions derived from the XGA display standard by widening it to a wide screen aspect ratio. WXGA is commonly used for low-end LCD TVs and LCD computer monitors for widescreen presentation. The exact resolution offered by a device described as "WXGA" can be somewhat variable owing to a proliferation of several closely related timings optimised for different uses and derived from different bases.

When referring to televisions and other monitors intended for consumer entertainment use, WXGA is generally understood to refer to a resolution of 1049088 !1366 × 768,786432 !1024 × 768 pixels, 4:3 aspect) extended to give square pixels on the increasingly popular 16:9 widescreen display ratio without having to effect major signalling changes other than a faster pixel clock, or manufacturing changes other than extending panel width by one third. As 768 does not divide exactly into 9, the aspect ratio is not quite 16:9 – this would require a horizontal width of 1365Template:1/3 pixels. However, at only 0.05%, the resulting error is insignificant.

A common variant on this resolution is 1044480 !1360 × 768, which confers several technical benefits, most significantly a reduction in memory requirements from just over to just under 1MB per 8-bit channel (1049088 !1366 × 768 needs 1024.5KB per channel; 1044480 !1360 × 768 needs 1020KB; 1MB is equal to 1024KB), which simplifies architecture and can significantly reduce the amount–and speed–of VRAM required with only a very minor change in available resolution, as memory chips are usually only available in fixed megabyte capacities. For example, at 32-bit color, a 1044480 !1360 × 768 framebuffer would require only 4MB, whilst a 1049088 !1366 × 768 one may need 5, 6 or even 8MB depending on the exact display circuitry architecture and available chip capacities. The 6-pixel reduction also means each line"s width is divisible by 8 pixels, simplifying numerous routines used in both computer and broadcast/theatrical video processing, which operate on 8-pixel blocks. Historically, many video cards also mandated screen widths divisible by 8 for their lower-color, planar modes to accelerate memory accesses and simplify pixel position calculations (e.g. fetching 4-bit pixels from 32-bit memory is much faster when performed 8 pixels at a time, and calculating exactly where a particular pixel is within a memory block is much easier when lines do not end partway through a memory word), and this convention still persisted in low-end hardware even into the early days of widescreen, LCD HDTVs; thus, most 1366-width displays also quietly support display of 1360-width material, with a thin border of unused pixel columns at each side. This narrower mode is of course even further removed from the 16:9 ideal, but the error is still less than 0.5% (technically, the mode is either 15.94:9.00 or 16.00:9.04) and should be imperceptible.

When referring to laptop displays or independent displays and projectors intended primarily for use with computers, WXGA is also used to describe a resolution of 1024000 !1280 × 800 pixels, with an aspect ratio of 16:10.both dimensions vs. the old standard (especially useful in portrait mode, or for displaying two standard pages of text side-by-side), a perceptibly "wider" appearance and the ability to display 720p HD video "native" with only very thin letterbox borders (usable for on-screen playback controls) and no stretching. Additionally, like 1044480 !1360 × 768, it required only 1000KB (just under 1MB) of memory per 8-bit channel; thus, a typical double-buffered 32-bit colour screen could fit within 8MB, limiting everyday demands on the complexity (and cost, energy use) of integrated graphics chipsets and their shared use of typically sparse system memory (generally allocated to the video system in relatively large blocks), at least when only the internal display was in use (external monitors generally being supported in "extended desktop" mode to at least 1920000 !1600 × 1200 resolution). 16:10 (or 8:5) is itself a rather "classic" computer aspect ratio, harking back all the way to early 64000 !320 × 200 modes (and their derivatives) as seen in the Commodore 64, IBM CGA card and others. However, as of mid 2013, this standard is becoming increasingly rare, crowded out by the more standardised and thus more economical-to-produce 1049088 !1366 × 768 panels, as its previously beneficial features become less important with improvements to hardware, gradual loss of general backwards software compatibility, and changes in interface layout. As of August 2013, the market availability of panels with 1024000 !1280 × 800 native resolution had been generally relegated to data projectors or niche products such as convertible tablet PCs and LCD-based eBook readers.

Widespread availability of 1024000 !1280 × 800 and 1049088 !1366 × 768 pixel resolution LCDs for laptop monitors can be considered an OS-driven evolution from the formerly popular 786432 !1024 × 768 screen size, which has itself since seen UI design feedback in response to what could be considered disadvantages of the widescreen format when used with programs designed for "traditional" screens. In Microsoft Windows operating system specifically, the larger task bar of Windows Vista and 7 occupies an additional 16 pixel lines by default, which may compromise the usability of programs that already demanded a full 786432 !1024 × 768 (instead of, e.g. 480000 !800 × 600) unless it is specifically set to use small icons; an "oddball" 784-line resolution would compensate for this, but 1024000 !1280 × 800 has a simpler aspect and also gives the slight bonus of 16 more usable lines. Also, the Windows Sidebar in Windows Vista and 7 can use the additional 256 or 336 horizontal pixels to display informational "widgets" without compromising the display width of other programs, and Windows 8 is specifically designed around a "two pane" concept where the full 16:9 or 16:10 screen is not required. Typically, this consists of a 4:3 main program area (typically 786432 !1024 × 768, 800000 !1000 × 800 or 1555200 !1440 × 1080) plus a narrow sidebar running a second program, showing a toolbox for the main program or a pop-out OS shortcut panel taking up the remainder.

XGA+ stands for Extended Graphics Array Plus and is a computer display standard, usually understood to refer to the 995328 !1152 × 864 resolution with an aspect ratio of 4:3. Until the advent of widescreen LCDs, XGA+ was often used on 17-inch desktop CRT monitors. It is the highest 4:3 resolution not greater than 220 pixels (≈1.05megapixels), with its horizontal dimension a multiple of 32 pixels. This enables it to fit closely into a video memory or framebuffer of 1MB (1 × 220 bytes), assuming the use of one byte per pixel. The common multiple of 32 pixels constraint is related to alignment.

Historically, the resolution also relates to the earlier standard of 1036800 !1152 × 900 pixels, which was adopted by Sun Microsystems for the Sun-2 workstation in the early 1980s. A decade later, Apple Computer selected the resolution of 1002240 !1152 × 870 for their 21-inch CRT monitors, intended for use as two-page displays on the Macintosh II computer. These resolutions are even closer to the limit of a 1MB framebuffer, but their aspect ratios differ slightly from the common 4:3.

WXGA+ (1296000 !1440 × 900) resolution is common in 19-inch widescreen desktop monitors (a very small number of such monitors use WSXGA+), and is also optional, although less common, in laptop LCDs, in sizes ranging from 12.1 to 17 inches.

Super Extended Graphics Array (SXGA) is a standard monitor resolution of 1310720 !1280 × 1024 pixels. This display resolution is the "next step" above the XGA resolution that IBM developed in 1990.

SXGA is the most common native resolution of 17 inch and 19 inch LCD monitors. An LCD monitor with SXGA native resolution will typically have a physical 5:4 aspect ratio, preserving a 1:1 pixel aspect ratio.

SXGA+ stands for Super Extended Graphics Array Plus and is a computer display standard. An SXGA+ display is commonly used on 14-inch or 15-inch laptop LCD screens with a resolution of 1470000 !1400 × 1050 pixels. An SXGA+ display is used on a few 12-inch laptop screens such as the ThinkPad X60 and X61 (both only as tablet) as well as the Toshiba Portégé M200 and M400, but those are far less common. At 14.1 inches, Dell offered SXGA+ on many of the Dell Latitude "C" series laptops, such as the C640, and IBM since the ThinkPad T21 . Sony also used SXGA+ in their Z1 series, but no longer produce them as widescreen has become more predominant.

In desktop LCDs, SXGA+ is used on some low-end 20-inch monitors, whereas most of the 20-inch LCDs use UXGA (standard screen ratio), or WSXGA+ (widescreen ratio).

WSXGA+ stands for Widescreen Super Extended Graphics Array Plus. WSXGA+ displays were commonly used on Widescreen 20-, 21-, and 22-inch LCD monitors from numerous manufacturers (and a very small number of 19-inch widescreen monitors), as well as widescreen 15.4-inch and 17-inch laptop LCD screens like the Thinkpad T61p, the late 17" Apple PowerBook G4 and the unibody Apple 15" MacBook Pro. The resolution is 1764000 !1680 × 1050 pixels (1,764,000 pixels) with a 16:10 aspect ratio.

UXGA has been the native resolution of many fullscreen monitors of 15 inches or more, including laptop LCDs such as the ones in ThinkPad A21p, A30p, A31p, T42p, T43p, T60p, Dell Inspiron 8000/8100/8200 and Latitude/Precision equivalents; Panasonic Toughbook CF-51; and the original Alienware Area 51m. However, in more recent times, UXGA is not used in laptops at all but rather in desktop UXGA monitors that have been made in sizes of 20 inches and 21.3 inches. Some 14-inch laptop LCDs with UXGA have also existed, but these were very rare.

WUXGA resolution has a total of 2,304,000 pixels. An uncompressed 8-bit RGB WUXGA image has a size of 6.75MB. As of 2014, this resolution is available in a few high-end LCD televisions and computer monitors (e.g. Dell Ultrasharp U2413, Lenovo L220x, Samsung T220P, ViewSonic SD-Z225, Asus PA248Q), although in the past it was used in a wider variety of displays, including 17-inch laptops. WUXGA use predates the introduction of LCDs of that resolution. Most QXGA displays support 2304000 !1920 × 1200 and widescreen CRTs such as the Sony GDM-FW900 and Hewlett Packard A7217A do as well. WUXGA is also available in some of the more high end mobile phablet devices such as the Huawei Honor X2 Gem.

The QXGA, or Quad Extended Graphics Array, display standard is a resolution standard in display technology. Some examples of LCD monitors that have pixel counts at these levels are the Dell 3008WFP, the Apple Cinema Display, the Apple iMac (27-inch 2009–present), the iPad (3rd generation), and the MacBook Pro (3rd generation). Many standard 21–22-inch CRT monitors and some of the highest-end 19-inch CRTs also support this resolution.

QWXGA (Quad Wide Extended Graphics Array) is a display resolution of 2359296 !2048 × 1152 pixels with a 16:9 aspect ratio. A few QWXGA LCD monitors were available in 2009 with 23- and 27-inch displays, such as the Acer B233HU (23-inch) and B273HU (27-inch), the Dell SP2309W, and the Samsung 2343BWX. As of 2011, most 2359296 !2048 × 1152 monitors have been discontinued, and as of 2013 no major manufacturer produces monitors with this resolution.

QXGA (Quad Extended Graphics Array) is a display resolution of 3145728 !2048 × 1536 pixels with a 4:3 aspect ratio. The name comes from it having four times as many pixels as an XGA display. Examples of LCDs with this resolution are the IBM T210 and the Eizo G33 and R31 screens, but in CRT monitors this resolution is much more common; some examples include the Sony F520, ViewSonic G225fB, NEC FP2141SB or Mitsubishi DP2070SB, Iiyama Vision Master Pro 514, and Dell and HP P1230. Of these monitors, none are still in production. A related display size is WQXGA, which is a wide screen version. CRTs offer a way to achieve QXGA cheaply. Models like the Mitsubishi Diamond Pro 2045U and IBM ThinkVision C220P retailed for around US$200, and even higher performance ones like the ViewSonic PerfectFlat P220fB remained under $500. At one time, many off-lease P1230s could be found on eBay for under $150. The LCDs with WQXGA or QXGA resolution typically cost four to five times more for the same resolution. IDTech manufactured a 15-inch QXGA IPS panel, used in the IBM ThinkPad R50p. NEC sold laptops with QXGA screens in 2002–05 for the Japanese market.iPad (starting from 3rd generation) also has a QXGA display.

To obtain a vertical refresh rate higher than 40Hz with DVI, this resolution requires dual-link DVI cables and devices. To avoid cable problems monitors are sometimes shipped with an appropriate dual link cable already plugged in. Many video cards support this resolution. One feature that is currently unique to the 30inch WQXGA monitors is the ability to function as the centerpiece and main display of a three-monitor array of complementary aspect ratios, with two UXGA (1920000 !1600 × 1200) 20-inch monitors turned vertically on either side. The resolutions are equal, and the size of the 1600 resolution edges (if the manufacturer is honest) is within a tenth of an inch (16-inch vs. 15.89999"), presenting a "picture window view" without the extreme lateral dimensions, small central panel, asymmetry, resolution differences, or dimensional difference of other three-monitor combinations. The resulting 7936000 !4960 × 1600 composite image has a 3.1:1 aspect ratio. This also means one UXGA 20-inch monitor in portrait orientation can also be flanked by two 30-inch WQXGA monitors for a 10112000 !6320 × 1600 composite image with an 11.85:3 (79:20, 3.95:1) aspect ratio. Some WQXGA medical displays (such as the Barco Coronis 4MP) can also be configured as two virtual 1920000 !1200 × 1600 or 2048000 !1280 × 1600 seamless displays by using both DVI ports at the same time.

An early consumer WQXGA monitor was the 30-inch Apple Cinema Display, unveiled by Apple in June 2004. At the time, dual-link DVI was uncommon on consumer hardware, so Apple partnered with Nvidia to develop a special graphics card that had two dual-link DVI ports, allowing simultaneous use of two 30-inch Apple Cinema Displays. The nature of this graphics card, being an add-in AGP card, meant that the monitors could only be used in a desktop computer, like the Power Mac G5, that could have the add-in card installed, and could not be immediately used with laptop computers that lacked this expansion capability.

In 2010, WQXGA made its debut in a handful of home theater projectors targeted at the Constant Height Screen application market. Both Digital Projection Inc and projectiondesign released models based on a Texas Instruments DLP chip with a native WQXGA resolution, alleviating the need for an anamorphic lens to achieve 1:2.35 image projection. Many manufacturers have 27–30-inch models that are capable of WQXGA, albeit at a much higher price than lower resolution monitors of the same size. Several mainstream WQXGA monitors are or were available with 30-inch displays, such as the Dell 3007WFP-HC, 3008WFP, U3011, U3014, UP3017, the Hewlett-Packard LP3065, the Gateway XHD3000, LG W3000H, and the Samsung 305T. Specialist manufacturers like NEC, Eizo, Planar Systems, Barco (LC-3001), and possibly others offer similar models. As of 2016, LG Display make a 10-bit 30-inch AH-IPS panel, with wide color gamut, used in monitors from Dell, NEC, HP, Lenovo and Iiyama.

QSXGA (Quad Super Extended Graphics Array) is a display resolution of 5242880 !2560 × 2048 pixels with a 5:4 aspect ratio. Grayscale monitors with a 5242880 !2560 × 2048 resolution, primarily for medical use, are available from Planar Systems (Dome E5), Eizo (Radiforce G51), Barco (Nio 5, MP), WIDE (IF2105MP), IDTech (IAQS80F), and possibly others.

Most display cards with a DVI connector are capable of supporting the 9216000 !3840 × 2400 resolution. However, the maximum refresh rate will be limited by the number of DVI links which are connected to the monitor. 1, 2, or 4 DVI connectors are used to drive the monitor using various tile configurations. Only the IBM T221-DG5 and IDTech MD22292B5 support the use of dual-link DVI ports through an external converter box. Many systems using these monitors use at least two DVI connectors to send video to the monitor. These DVI connectors can be from the same graphics card, different graphics cards, or even different computers. Motion across the tile boundary(ies) can show tearing if the DVI links are not synchronized. The display panel can be updated at a speed between 0Hz and 41Hz (48Hz for the IBM T221-DG5, -DGP, and IDTech MD22292B5). The refresh rate of the video signal can be higher than 41Hz (or 48Hz) but the monitor will not update the display any faster even if graphics card(s) do so.

In June 2001, WQUXGA was introduced in the IBM T220 LCD monitor using a LCD panel built by IDTech. LCD displays that support WQUXGA resolution include: IBM T220, IBM T221, Iiyama AQU5611DTBK, ViewSonic VP2290,IDTech MD22292 (models B0, B1, B2, B5, C0, C2). IDTech was the original equipment manufacturer which sold these monitors to ADTX, IBM, Iiyama, and ViewSonic.Hz and 48Hz, made them less attractive for many applications.

A common size for LCDs manufactured for small consumer electronics, basic mobile phones and feature phones, typically in a 1.7" to 1.9" diagonal size. This LCD is often used in portrait (128×160) orientation. The unusual 5:4 aspect ratio makes the display slightly different from QQVGA dimensions.

Half the resolution in each dimension as standard VGA. First appeared as a VESA mode (134h=256 color, 135h=Hi-Color) that primarily allowed 80x30 character text with graphics, and should not be confused with CGA (320x200); QVGA is normally used when describing screens on portable devices (PDAs, pocket media players, feature phones, smartphones, etc.). No set colour depth or refresh rate is associated with this standard or those that follow, as it is dependent both on the manufacturing quality of the screen and the capabilities of the attached display driver hardware, and almost always incorporates an LCD panel with no visible line-scanning. However, it would typically be in the 8-to-12 bpp (256–4096 colours) through 18 bpp (262,144 colours) range.

Atari ST line. High resolution monochrome mode using a custom non-interlaced monitor with the slightly lower vertical resolution (in order to be an integer multiple of low and medium resolution and thus utilize the same amount of RAM for the framebuffer) allowing a "flicker free" 71.25 Hz refresh rate, higher even than the highest refresh rate provided by VGA. All machines in the ST series could also use colour or monochrome VGA monitors with a proper cable or physical adapter, and all but the TT could display 640x400 at 71.25 Hz on VGA monitors.

Commodore Amiga line and others, e.g. Acorn Archimedes, Atari Falcon). They used NTSC or PAL-compliant televisions and monochrome, composite video or RGB-component monitors. The interlaced (i or I) mode produced visible flickering of finer details, eventually fixable by use of scan doubler devices and VGA monitors.

The second-generation Macintosh, launched in 1987, came with colour (and greyscale) capability as standard, at two levels, depending on monitor size—512×384 (1/4 of the later XGA standard) on a 12" (4:3) colour or greyscale (monochrome) monitor; 640×480 with a larger (13" or 14") high-resolution monitor (superficially similar to VGA, but at a higher 67 Hz refresh rate)—with 8-bit colour/256 grey shades at the lower resolution, and either 4-bit or 8-bit colour (16/256 grey) in high resolution depending on installed memory (256 or 512 kB), all out of a full 24-bit master palette. The result was equivalent to VGA or even PGC—but with a wide palette—at a point simultaneous with the IBM launch of VGA.

Later, larger monitors (15" and 16") allowed use of an SVGA-like binary-half-megapixel 832×624 resolution (at 75 Hz) that was eventually used as the default setting for the original, late-1990s iMac. Even larger 17" and 19" monitors could attain higher resolutions still, when connected to a suitably capable computer, but apart from the 1152×870 "XGA+" mode discussed further below, Mac resolutions beyond 832×624 tended to fall into line with PC standards, using what were essentially rebadged PC monitors with a different cable connection. Mac models after the II (Power Mac, Quadra, etc.) also allowed at first 16-bit High Colour (65,536, or "Thousands of" colours), and then 24-bit True Colour (16.7M, or "Millions of" colours), but much like PC standards beyond XGA, the increase in colour depth past 8 bpp was not strictly tied to changing resolution standards.

The first PowerBook, released in 1991, replaced the original Mac Portable (basically an original Mac with an LCD, keyboard and trackball in a lunchbox-style shell), and introduced a new 640×400 greyscale screen. This was joined in 1993 with the PowerBook 165c, which kept the same resolution but added colour capability similar to that of Mac II (256 colours from a palette of 16.7 million).

Introduced in 1984 by IBM. A resolution of 640×350 pixels of 16 different colours in 4 bits per pixel (bpp), selectable from a 64-colour palette in 2 bits per each of red-green-blue (RGB) unit.DIP switch options; plus full EGA resolution (and CGA hi-res) in monochrome, if installed memory was insufficient for full colour at above 320×200.

Introduced by IBM on ISA-based PS/2 models in 1987, with reduced cost compared to VGA. MCGA had a 320×200 256-colour (from a 262,144 colour palette) mode, and a 640×480 mode only in monochrome due to 64k video memory, compared to the 256k memory of VGA.

The high-resolution mode introduced by 8514/A became a de facto general standard in a succession of computing and digital-media fields for more than two decades, arguably more so than SVGA, with successive IBM and clone videocards and CRT monitors (a multisync monitor"s grade being broadly determinable by whether it could display 1024×768 at all, or show it interlaced, non-interlaced, or "flicker-free"), LCD panels (the standard resolution for 14" and 15" 4:3 desktop monitors, and a whole generation of 11–15" laptops), early plasma and HD ready LCD televisions (albeit at a stretched 16:9 aspect ratio, showing down-scaled material), professional video projectors, and most recently, tablet computers.

An extension to VGA defined by VESA for IBM PC-compatible computers in 1989 meant to take advantage of video cards that exceeded the minimum 256 kB defined in the VGA standard. For instance, one of the early supported modes was 800×600 in 16 colours at a slightly lower 56 Hz refresh rate, leading to 800×600 sometimes being referred to as "SVGA resolution" today.

An IBM display standard introduced in 1990. XGA built on 8514/A"s existing 1024×768 mode and added support for "high colour" (65,536 colours, 16 bpp) at 640×480. The second revision ("XGA-2") was a more thorough upgrade, offering higher refresh rates (75 Hz and up, non-interlaced, up to at least 1024×768), improved performance, and a fully programmable display engine capable of almost any resolution within its physical limits. For example, 1280×1024 (5:4) or 1360×1024 (4:3) in 16 colours at 60 Hz, 1056×400 [14h] Text Mode (132×50 characters); 800×600 in 256 or 64k colours; and even as high as 1600×1200 (at a reduced 50 Hz scan rate) with a high-quality multisync monitor (or an otherwise non-standard 960×720 at 60 Hz on a lower-end one capable of high refresh rates at 800×600, but only interlaced mode at 1024×768).I, 640×480×16 NI, high-res text) were commonly used outside Windows and other hardware-abstracting graphical environments.

A widely used aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1.33:1), meaning that even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution—with, therefore, square pixels—of standard 17" and 19" LCD monitors. It was often a recommended resolution for 17" and 19" CRTs also, though as they were usually produced in a 4:3 aspect ratio, it either gave non-square pixels or required adjustment to show small vertical borders at each side of the image. Allows 24-bit colour in 4 MB of graphics memory, or 4-bit colour in 640 kB.

An enhanced version of the WXGA format. This display aspect ratio was common in widescreen notebook computers, and many 19" widescreen LCD monitors until ca. 2010.

A wide version of the SXGA+ format, the native resolution for many 22" widescreen LCD monitors, also used in larger, wide-screen notebook computers until ca. 2010.

This display aspect ratio is the native resolution for many 24" widescreen LCD monitors, and is expected to also become a standard resolution for smaller-to-medium-sized wide-aspect tablet computers in the near future (as of 2012).

A wide version of the UXGA format. This display aspect ratio was popular on high-end 15" and 17" widescreen notebook computers, as well as on many 23–27" widescreen LCD monitors, until ca. 2010. It is also a popular resolution for home cinema projectors, besides 1080p, in order to show non-widescreen material slightly taller than widescreen (and therefore also slightly wider than it might otherwise be), and is the highest resolution supported by single-link DVI at standard colour depth and scan rate (i.e., no less than 24 bpp and 60 Hz non-interlaced)

This is the highest resolution that generally can be displayed on analog computer monitors (most CRTs), and the highest resolution that most analogue video cards and other display transmission hardware (cables, switch boxes, signal boosters) are rated for (at 60 Hz refresh). 24-bit colour requires 9 MB of video memory (and transmission bandwidth) for a single frame. It is also the native resolution of medium-to-large latest-generation (2012) standard-aspect tablet computers.

A version of the XGA format, the native resolution for many 30" widescreen LCD monitors. Also, the highest resolution supported by dual-link DVI at a standard colour depth and non-interlaced refresh rate (i.e. at least 24 bpp and 60 Hz). Used on MacBook Pro with Retina display (13.3"). Requires 12 MB of memory/bandwidth for a single frame.

A digital format in testing by NHK in Japan (with a partnership extending to BBC for test coverage of the 2012 London Olympic Games), intended to provide effectively "pixel-less" imagery even on extra-large LCD or projection screens.
