Traditionally, computer mice are what have allowed us to "touch" in a virtual context, but touchscreen monitors are changing all that. It might be said that the reason that mice were used in the first place was because the technology had not evolved to a responsive enough level to enable that natural solution. Now that people have the touchscreen technology, they want it everywhere.

If one thing is for certain, it is that the burgeoning adoption of touchscreen technology is no fad. Proliferation has already come too far to turn back now, and computer manufacturers are taking notice. Everyone is trying to get a piece of the action, including ELO Touch Solutions, Laiputuo Electronics, Planar, HP, 3M, Touch Systems, ViewSonic, Dell and ACER as well. Getting into the touchscreen monitor game is a no-brainer for the companies involved in this generation of computing. With so many different applications made for touchscreen monitors, options exist for all sorts of interested parties.

Touchscreen monitors are becoming the new standard in both private and enterprise settings. Here are some of the ways they can be leveraged effectively for business: touchscreen monitors for workstations, touchscreen monitors for hospitals, and touchscreen monitors for POS systems.

Newegg offers a large selection of touchscreen monitors which vary according to the type from 5-wire Resistive touchscreen monitors, and Accu Touch touchscreen monitors, to Capacitive touchscreen monitors, and more. Newegg’s wide selections will definitely meet your needs.

The “Nearest Neighbour” interpolation is only lossless at integer ratios of sizes of resulting and original images, but results in distortion at fractional ratios due to different sizes of resulting pixels:

If resolutions of the display and the image are not divisible, the image is scaled with such an integer ratio that results in filling the screen as fully as possible, and the rest screen space is filled with black background the same way as when the image is centered on the screen with no scaling.

With 4K monitors of 24—27″ size at Full HD resolution, single image pixels are almost indistiguishable, so blur does not add any smoothing and just senselessly decreases sharpness resulting in an unreasonable quality loss.

When using even integer scales in conjunction with 4:2:2 or 4:2:0 chroma subsampling, integer-ratio scaling on signal-source side allows to decrease needed video-interface bandwidth by two or four times correspondingly with no quality loss. For example, 4K at 4:2:0 needs the same bandwidth as Full HD at 4:4:4.

For example, at the 320×240 resolution typical for DOS games, just 89% of the height of a Full HD (1920×1080) display is used (used 960 of 1080 pixels with the ratio of 4), while the height of a 4K monitor is used entirely (scale is exactly 9).

For example, for the resolution of 256×224 typical for 16-bit game consoles such as SNES and Sega Genesis (Mega Drive), the maximum integer ratio on a Full HD display is 4 (the full fractional ratio is 4.82), so 184 pixels are lost vertically by default, or 17% of the screen height.

With a higher-resolution display, it’s possible to achieve a more precise aspect ratio of the image when doing integer scaling with aspect-ratio correction enabled.

For example, for the resolution of 256×224 typical for 16-bit game consoles such as SNES and Sega Genesis (Mega Drive), on a 4K display, aspect-ratio error relative to the perfect aspect ratio of 4:3 is 5%, while on a 8K display, the error is below 1%.

On 8K displays, integer-ratio scaling allows to use with no loss of quality or screen space, any of the typical resolutions, effectively allowing to flexibly change the native display resolution:

In Windows 10, for games with support for the “Borderless” pseudo-full-screen mode (a window with no borders that has a size of entire screen), it’s possible to use nonblurry scaling with a ratio equal to system-level zoom.

Depending on whether the area aspect-ratio is lower or greater than the target one, make the needed horizontal or vertical integer scale equal to the maximum one on this axis.

Calculate the width UW and the height UH of the scaled image by multiplying, correspondingly, the width W and the height H of the original image by the ratio R.

With a proper implementation of integer-ratio scaling, the results of scaling the provided original images must be identical to the provided reference renderings of scaled images.

The simplest user interface for controlling nonblurry upscaling could be represented by a single checkbox “Prevent blur when upscaling” intended for enabling integer-ratio scaling with no blur.

The first one enables/disables blur, the second one enables/disables using solely integer ratios for pixel-perfect upscaling with no distortion of the image.

With integer-ratio scaling, the scale is always integer (e. g. exactly 4 in the 640×480→4K case) — regardless of the native-to-logical resolution ratio.

comfort during working with text in any way (web surfing, text editors, programming, web development), drawings, charts is enormously higher on a 4K monitor than on a FHD monitor, thanks to the increased detail, invisible interpixel grid and greatly decreased sequential flickering of sub­pixels caused by crystal inversion specific to the LCD technology;

For example, when scaling 320×240 to Full HD, 1/9 (11%) of the screen height is lost (filled with black) (1080/240 = 4,5), while on a 4K display, the ratio is exactly 9, so the image occupies the entire height of the screen.

While developers of a specific game could indirectly utilize this feature for integer-ratio scaling in this specific game, scaling textures is not directly related to universal full-screen scaling transparent to operating system and software.

When using integer-ratio scaling, the image is rendered at a resolution lower than the native display resolution and then upscaled (stretched) with no blur to the resolution less than or equal to the display resolution while using a highest possible integer scale.

The only thing that DSR/VSR and integer-ratio scaling share is the universal resolution virtualization transparent to operating system and software and compatible with all full-screen applications.

Integer-ratio scaling with no blur is free of quality loss caused by blur, and a proper implementation should be compatible with all full-screen applications.

With integer-ratio scaling with no blur, all image pixels are rendered, then the image is upscaled without altering it in any way and calculating any average colors.

The feature is available for GPUs of multiple previous generations starting with the 2nd-generation GCN architecture (2013) including GPUs of the R7 260, R9 285 and R9 290 series.

The AMD implementation of integer scaling reportedly allows to combine integer scaling with Radeon Image Sharpening (RIS) and VSR, that, along with support for previous-generation GPUs, is an advantage over the nVidia’s implementation.

Combining VSR with integer scaling potentially allows e.g. entirely use Full HD screen height at logical resolution of 320×240 (pure ratio is 4.5) at the cost of some blur of pixel edges as a result of turning the native Full HD resolution into the virtual 4K (the ratio is exactly 9).

Based on the program code and the description of the patch from October 17, 2019, integer-ratio scaling is going to be transparently used in the existing Centered mode and is not going to be available as a separate scaling mode.

Support for nonblurry full-screen integer-ratio scaling is available in the Intel graphics driver for Windows since the beta version 25.20.100.7155 (2019-08-30).

“Scaled width” means just using the “Nearest neighbour” resizing algorithm, while “Fixed width” is Nearest neighbour combined with using solely integer ratios to prevent image distortion — i. e. integer scaling.

Support for integer scaling is available in nVidia driver for Windows since the version 436.02 (2019-08-20), but only when using graphics cards of the Turing generation (RTX and GTX 16*) and only in Windows 10 version 1803+ (Redstone 4) released on April 2018.

According to nVidia, incompatibility with HDR and custom resolutions is an unsurpassable fundamental limitation of the programmable filter used to implement integer scaling, and this can’t be fixed at least for Turing-generation nVidia GPUs.

Eve/Dough Spectrum are the world’s first computer monitors with built-in pixel-perfect (integer) scaling. The feature is already implemented and does work: tested by yours truly.

The monitors are based on LCD panels “Nano IPS” produced by LG Display, with a response time of 1 ms and support for variable refresh rate (VRR) “FreeSync Premium Pro” (“G-Sync Compatible”) with a minimal rate of 48 Hz and high dynamic range (HDR): HDR600 for the higher-level models and HDR400 for the lower-level one.

The aspect ratio of a LCD display is the proportional relationship of its width compared to its height. The two numbers are commonly separated by a colon. The most common aspect ratios are 16:9 (aka widescreen) and 4:3 (closer to the shape of a square monitor, such as old CRT’s and TV’s). It is best to choose a monitor with the same aspect ratio as your video signal. You cannot customize a monitor’s native aspect ratio, so it is critical to know the aspect ratio of your incoming video signal beforehand. Use this handy screen ratio calculator to determine what you need.
