imac 27 lcd panel manufacturer

I"ve had problems with image retention on my late-2012 27" iMac for a few months now and Apple"s "avoiding image retention" support page is useless for me.

On MacBooks, one can use this Terminal one-liner to check one"s display manufacturer. Is there a similar command for iMacs? I realize that I"ll have to return my iMac sooner or later because this is unacceptable, but I"d still like to know what panel I have before I do it.

Apple Inc. sold a variety of LCD and CRT computer displays in the past. Apple paused production of their own standalone displays in 2016 and partnered with LG to design displays for Macs.Pro Display XDR was introduced, however it was expensive and targeted for professionals. Nearly three years later, in March 2022, the Studio Display was launched as a consumer-targeted counterpart to the professional monitor. These two are currently the only Apple-branded displays available.

The Macintosh Color Classic introduced a 10″ color Trinitron display to the Classic compact Macintosh, with a slightly enhanced resolution of 512×384 (560×384 to accommodate the Apple IIe Card) like the standalone 12″ color display. Apple continued the all-in-one series with the larger 14″ Macintosh LC 500 series, featuring a 14″, 640×480 Trinitron CRT until the LC 580 in 1995, which heralded the switch to shadow mask CRTs for the remainder of Apple"s all-in-one computers until the switch to LCDs in 2002. The last Macintosh to include an integrated CRT was the eMac, which boosted the display area to 17″ with support up to 1280×960 resolution. It used a 4th generation flat-screen CRT and was discontinued in 2006.

The fourth generation of displays were introduced simultaneously with the Blue & White Power Macintosh G3 in 1999, which included the translucent plastics of the iMac (initially white and blue "blueberry", then white and grey "graphite" upon the introduction of the Power Mac G4). The displays were also designed with same translucent look. The Apple Studio Display series of CRT displays were available in a 17″ Diamondtron and a 21″ Trinitron CRT, both driven by an LG-Manufactured chassis. The 17″ displays were notorious for faulty flybacks and failing in a manner that could destroy the monitor and catch fire. It"s also reported that these monitors can destroy GPU"s, and sometimes the entire computer. The last Apple external CRT display was introduced in 2000 along with the Power Mac G4 Cube. Both it and the new LCD Studio Displays featured clear plastics to match the Cube, and the new Apple Display Connector, which provided power, USB, and video signals to the display through a single cable. It was available only in a 17″ flat screen Diamondtron CRT. It was discontinued the following year.

The history of Apple LCDs started in 1984 when the Apple Flat Panel Display was introduced for the Apple IIc computer, principally to enhance the IIc"s portability (see Apple IIc Portability enhancements). This monochrome display was capable of 80 columns by 24 lines, as well as double hi-res graphics, but had an odd aspect ratio (making images look vertically squished) and required a very strong external light source, such as a desk lamp or direct sunlight to be used. Even then it had a very poor contrast overall and was quite expensive (US$600), contributing to its poor sales and consequently it dropping from the market not long after its introduction. An estimated 10,000 IIc LCD displays were produced.

The next attempt at a flat panel was with the Macintosh Portable. More of a "luggable" than a laptop, it contained a high-resolution, active-matrix, 1-bit black & white, 9.8″ LCD with 640×400 resolution. Like the IIc Flat Panel, it was not backlit and required a bright light source to be used. A second generation model employed a backlit LCD. The PowerBook and MacBook series would continue to use LCD displays, following an industry-wide evolution from black-and-white to grayscale to color and ranging from 9″ to 17″. Two primary technologies were used, active matrix (higher quality and more expensive) and passive matrix displays (lower quality and cheaper). By 1998 all laptops would use active-matrix color LCDs, though the Newton products and eMate portables would continue to use black and white LCDs. Apple"s current MacBook portable displays include LED backlighting and support either 2560×1600 or 2880×1800 pixel resolutions depending on screen size. The iPod series used black-and-white or color LCDs, the iPhone line uses LCD and OLED displays, and the Apple Watch uses OLED.

In 1997, Apple released the Twentieth Anniversary Macintosh (TAM), its first all-in-one desktop with an LCD display. Drawing heavily from PowerBook technology, the TAM featured a 12.1″ active matrix LCD capable of displaying up to 16 bit color at 800×600. While Apple chose to retain traditional and cheaper CRTs for its all-in-one desktop line for the next 4 years, the TAM is undoubtedly the predecessor for the successful LCD-based iMac line of all-in-one desktops starting with the iMac G4 released in 2002. A substantial upgrade over the TAM, it contained a 15″ LCD supporting up to 1024×768 resolution. It was followed by a 17″ and 20″ models boasting resolution of up to 1680 × 1050. In 2005, the iMac G5 dropped the 15″ configuration and in 2007, the new iMac dropped the 17″ and added a 24″ to the line-up, further boosting resolution to 1920 x 1200. In October 2009, new iMac models moved to 16:9 aspect ratio screens at 21.5 and 27 inches.

The first desktop color flat-panel was introduced on March 17, 1998, with the 15″ Apple Studio Display (15-inch flat panel) which had a resolution of 1024×768. After the eMate, it was one of the first Apple products to feature translucent plastics, two months before the unveiling of the iMac. Apple called its dark blue color "azul". It had a DA-15 input as well as S-video, composite video, ADB and audio connectors, though no onboard speakers. In January 1999 the coloring was changed to match the blue and white of the new Power Macintosh G3s, and the connector changed to DE-15 VGA.

The 22″ widescreen Power Mac G4 and in the beginning was sold only as an option to the Power Mac G4, selling for US$3,999. It had a native resolution of 1600×1024 and used a DVI connector. The display had a striped look on the bezel, similar to previous Studio Displays and iMacs. In December, the colors of the 15″ display were changed to "graphite" to match the new Power Mac G4s, and the input was changed from VGA to DVI, the audio and video features dropped, and the ADB functionality replaced by a two-port USB hub.

In 2000 the 22″ Cinema Displays switched to the ADC interface, and the 15″ Studio Display was remodeled to match the Cinema Display"s easel-like form factor and also featured the Apple Display Connector. In 2001 an LCD-based 17″ Studio Display was introduced, with a resolution of 1280×1024. In 2002 Apple introduced the

In 2004 a new line was introduced, utilizing the same 20″ and 23″ panels alongside a new 30″ model, for $3,299. The displays had a sleek aluminum enclosure with a much narrower bezel than their predecessors. The 20″ model featured a 1680×1050 resolution, the 23″ 1920×1200, and the 30″ 2560×1600. The 30″ version requires a dual-link interface, because a single-link DVI connection (the most common type) doesn"t have enough bandwidth to provide a picture to a display of this resolution. Initially, the only graphics cards that could power the new 30″ display were the Nvidia GeForce 6800 DDL series, available in both GT and Ultra forms. The DDL suffix signified the dual-link DVI capability. The less expensive of the two cards retailed for US$499, raising the net cost of owning and using the display to nearly $3,800. Later graphics options included the NVIDIA Quadro FX 4500; the card included two dual-link DVI connectors which allowed a Power Mac G5 to run two 30″ Cinema Displays simultaneously with the total number of pixels working out to 8.2 million.

With the introduction of the Unibody MacBook family, Apple introduced the 24-inch LED Cinema Display, its first desktop display to use the new Mini DisplayPort connector, and also the first with an LED-backlit LCD. It had built-in speakers, a powered 3-port USB hub on the rear, an iSight camera and microphone, and a MagSafe power adapter for laptops. It also connected by USB for peripherals. It has a resolution of 1920×1200 and retailed for US$899.00. In 2010 it was replaced with a new 27-inch version with a resolution of 2560×1440.

After Apple discontinued production of standalone displays in 2016, they partnered with LG to design the UltraFine line, with a 21.5-inch 4K display and 27-inch 5K display (27MD5KA-B), released in November 2016 alongside the Thunderbolt 3-enabled MacBook Pro.USB-C connector, with the 27-inch version integrating Thunderbolt 3 connectivity. On the rear of the displays is a three port USB-C hub. The 21.5-inch version provides up to 60W charging power, while the 27-inch provides up to 85W. The 21.5-inch is compatible with all Macs with a USB-C port, while the 27-inch version can only be used natively at full resolution with Macs with Thunderbolt 3, which includes all Macs with USB-C except the Retina MacBook. The 27-inch model is compatible with older Thunderbolt 2-equipped Macs using an adapter, but is limited to displaying their maximum output resolution.

In May 2019 the 21.5-inch model was discontinued and replaced with a 23.7-inch model which added Thunderbolt 3 connectivity and increased the power output to 85W. In July 2019, the 27-inch model (27MD5KL-B) was updated with USB-C video input, adding compatibility with the 3rd generation iPad Pro at 4K resolution, and increased power output to 94W.Apple Studio Display, but the display is still in production according to LG.

Apple announced the Pro Display XDR at the 2019 WWDC, the first Apple-branded display since the Apple Thunderbolt Display was discontinued in 2016. The display contains a 6016×3384 6K color-calibrated Extreme Dynamic Range (XDR) panel.

Apple announced the Apple Studio Display at the March 2022 Apple Special Event. It features a 27-inch, 5K Retina monitor, with 5120-by-2880 resolution at 218 pixels per inch, 600 nits brightness, wide color (P3), and True Tone technology.

A DVI connector was used on the 2001-2002 titanium PowerBook G4; all aluminum PowerBook G4 15” and 17”; all aluminum MacBook Pro 15″ and 17″ models; Mac Mini G4, Power Mac G4, G5; Intel Mac Mini, and Mac Pro 2006–2012. PowerBook G4 12”, iMac G5 and Intel white iMacs mini-DVI ports.

According to Reuters, the continued losses suffered by the company is due to "sagging prices" for LCD panels across the board. The company also said its production plans in South Korea and China could be impacted by the emerging trade war between the U.S. and China.

LG Display cited "concern for the global smartphone market," as well as the long-term decline of LG"s LCD panel business. The company has been shifting its emphasis towards OLED panels.

A report earlier this month stated that Apple has ordered between 3 and 4 million OLED panels from LG Display, for use in the 2018 generation of iPhones, with LG expected to become the majority supplier of OLED panels for iPhones for 2019, overtaking its rival Samsung.

There had been reports in April of manufacturing delays on LG"s side affecting Apple"s panel diversifaction plans. As of June, LG was expected to deliver 2 million and 4 million OLED panels to Apple for "a future iPhone," although it"s unclear whether they would be used in this year"s or next year"s models.

LG Display has long been a supplier of 4K and 5K panels for the iMac. LG Display and Samsung both supply screens for the Apple Watch, while LG Display supplies Pad screens as well.

While most reports are pointing to the 2022 27-inch iMac using the same mini-LED backlighting system as the latest MacBook Pro models, a fresh supply chain report today disagrees.

All current Macs use LCD screens, with LEDs used behind the display to provide backlighting. However, the 2021 14- and 16-inch MacBook Pro models adopted mini-LED backlighting.

Display analyst Ross Young said in October that a new 27-inch iMac would debut next year with a mini-LED screen with the same 120Hz ProMotion capabilities as the latest MacBook Pro models. We noted then Young’s credentials.

Suppliers have kicked off their shipments in small volume for 27-inch iMac series that will come with a mini LED display, according to industry sources.

Suppliers have kicked off their shipments in small volume for the new 27-inch iMac set for launch in 2022, but the device will not come with a miniLED display as previously speculated, according to industry sources.

The sources pointed out that speculation about the next-generation 27-inch iMac coming with a miniLED display has been circulating in the market ever since the 24-inch iMac received a major upgrade in the CPU platform earlier this year, but the shipments of the 27-inch device in December showed that it is still equipped with a traditional LCD display.

If true, this would be more backlighting LEDs than existing iMac displays, but not as many as in the latest MacBook Pro models – which would seem odd.

The Apple Studio Display is aimed at a very different audience, and with a $1,599 price tag it isn’t exactly pocket change, but it does something really important. Pair it with the freshly launched Mac Studio, and it finally decouples the screen from the computer. For a company that likes to shout about its environmental chops, it’s about damn time… The number of iMacs I’ve sold because the processor is slow as winter molasses while the screen is still in perfect shape has been a source of infinite frustration. Being able to upgrade just the screen or just the brains of the workstation, while staying within the Apple ecosystem, has been a long time coming.

Oh, yeah, and it has a screen, too. It packs in a 27-inch 5K retina display with 600 nits of brightness and an extra-wide color gamut.

The Apple Studio Display (stylized and marketed as Studio Display) is a 27-inch flat panel computer monitor developed and sold by Apple Inc.Mac Studio desktop and was released on March 18, 2022. It is Apple"s consumer display, sitting below the Pro Display XDR.

The Studio Display is the first Apple-branded consumer display released since the Apple Thunderbolt Display, which was released in 2011 and discontinued in 2016.LG to design the Thunderbolt 3-enabled UltraFine line, consisting of a 21.5-inch 4K and a 27-inch 5K display.

The Studio Display features a 27-inch, 5K LED-backlit panel, with 5120×2880 resolution at 218 pixels per inch and 600 nits of brightness, an increase from the 500 nits panel used in the LG UltraFine and 27-inch iMac.P3 wide color and True Tone technology.HDR content.spatial audio and Dolby Atmos, and a three-microphone array that supports "Hey Siri".Thunderbolt 3 port that supports DisplayPort 1.4 with Display Stream Compression (DSC) 1.2 and provides up to 96 W of host charging for connected laptops, and three downstream 10 Gbit/s USB-C ports.

Look, people have wanted Apple to sell the 5K display from the now-discontinued 27-inch iMac as a standalone product for years now. When that first 27-inch 5K iMac came out in 2014, the display was so far ahead of the competition that buying one for the screen alone represented a bargain — that there was an entire computer attached to it was almost a bonus.

So now Apple’s gone and discontinued the 27-inch iMac and essentially replaced it with the new Mac Studio and the new 27-inch Studio Display. If the Mac Studio represents the fulfillment of a 20-year-old Mac power user’s dream, the Studio Display should be the fulfillment of a similar dream that’s been around since 2014: just give us the iMac’s 27-inch 5K display.

Apple is generally terrific when it comes to displays across its devices, and the Studio Display is great at the basics: it’s clear, it’s sharp, it’s bright. If you have ever looked at a 27-inch 5K iMac display, you know exactly what this thing looks like. The Studio display is the same 27-inch size, the same 5120x2880 resolution, the same 218 pixels per inch, the same 60Hz refresh rate, and has the same single-zone LED backlight. The only real spec difference is that Apple says the Studio Display now has a “typical brightness” of 600 nits vs. 500 on the iMac, but in my actual typical use next to a 2015-vintage 27-inch iMac, that’s pretty hard to see.

The real issue is that $1,599 is a lot of money, and here, it’s buying you panel tech that is woefully behind the curve. Compared to Apple’s other displays across the Mac, iPhone, and iPad lineup, the Studio Display is actually most notable for the things it doesn’t have.

The Studio Display has… well, it has none of that. It’s a regular old LED backlight that lights the entire screen all the time, and the darkest black it can produce is basically gray. In normal use in a well-lit room, it looks fine enough — LCD displays have looked like this for a long time now — but if you’re watching a movie in a dark room, the letterboxing will look light gray. There are $379 TVs with more advanced local-dimming backlights than this.

Our rule has always been to review products based on what we have in front of us and never against the promise of a future software update, and based on what I have in front of me, I simply wouldn’t want to use this camera. The cameras on the new MacBook Pro and M1 iMac are far superior to what we’re seeing here, and an iPhone front camera is even better still. I’m hopeful Apple will improve things via software in the future, but I would not spend $1,599 on this display until that actually happens.
