Apple today unveiled the 27-inch iMac with Retina 5K display, featuring the world's highest resolution display with a breathtaking 14.7 million pixels. At this amazing resolution, text appears sharper than ever, videos are unbelievably lifelike, and you can see new levels of detail in your photos. With the latest quad-core processors, high-performance graphics, Fusion Drive and Thunderbolt 2, iMac with Retina 5K display is the most powerful iMac ever made - it's the ultimate display combined with the ultimate all-in-one.

"Thirty years after the first Mac changed the world, the new iMac with Retina 5K display running OS X Yosemite is the most insanely great Mac we have ever made," said Philip Schiller, Apple's senior vice president of Worldwide Marketing. "With a breathtaking 14.7 million pixel display, faster CPU and graphics, Fusion Drive, and Thunderbolt 2, it's the most beautiful and powerful iMac ever."

Samsung Display announced today that it is showcasing several industry-leading technologies and mobile to extra-large-sized display prototypes at the Society for Information Display's Display Week 2013, May 21-23, 2013, in the Vancouver Convention Centre (Booth 700). These include a Full HD (1920x1080) mobile AMOLED display with the world's broadest color gamut, and an 85-inch Ultra HD (3840×2160) LCD TV panel with extremely vivid color and low power consumption.

In addition, Samsung Display shows a unique new Diamond Pixel technology being highlighted at the show, and a featured LCD technology that enables local-dimming control in direct LED-based LCD panels. The world's first mass-produced 4.99-inch Full HD mobile AMOLED display offers the world's broadest color gamut with a 94 percent average rate of reproduction for the Adobe RGB color space. The Adobe RGB standard is about 30 percent broader than general sRGB standards.

Come 2013, and PC consumers could finally break the shackles of regressive PC resolution "standards" such as 1366x768 and 1920x1080, if Intel has its way. At a presentation at IDF Beijing, Intel expressed its desire to see much higher resolution displays for all computing devices, not just PCs, which could in true terms be "retina-matched" display resolutions. At an optimal (comfortable) viewing distance, the resolution of a computing device's screen should match that of your eyes.

If Intel has its way, a 21" all-in-one desktop PC, and a 15" notebook PC screen will have a resolution of 3840x2160 pixels; a 13" Ultrabook PC could have a resolution of 2800x1800 pixels, a 11" Ultrabook and 10" tablet with 2560x1440, and 5" handheld/smartphone with 1280x800. Compare these to the $500+ 27" 1920x1080 monitors that are still sold in the market! A very bold proposal, but one only a company with the industry prominence of Intel can pull off.

c|net has tried out a laptop prototype from Tobii at the Consumer Electronics Show, that can be controlled with the eyes - and it works. The reporter, Rafe Needleman, was initially sceptical, as the eyes are only designed for input not output, but it turned out to be very fast and intuitive for him. It works by having the user press the Windows key, look at a tile and then release the key to activate the tile. The use of the keypress prevents one's eyes, which tend to dart around in normal use, from scrambling input to the laptop. As the user's gaze darts over the screen, the system gives an indication as to which tile is currently selected by the user's gaze to ensure accurate tile selection by the user.

To achieve this feat, the modified laptop uses two infra red emitters and two special IR cameras along the Windows 8 customer preview released a while back. They use "the reflective point of the retina, plus the glint off the cornea" Rafe was told. From this, the computer builds a 3D model of the user's gaze to work out where they are looking on the screen. Rafe concluded, "I did not expect to like it, but I did. It is intuitive to use, and very fast. Tobii has done a good job of making your glances into workable input signals."

Apple sure knows how to surprise us when it comes to display advancements, be it its retina display on iPhone products, 2560 x 1440 pixels in 27-inch monitors (Apple was first to market with that density), or talk of 2048 x 1536 pixels native resolution with the next generation iPad. This latest news is bound to shock and awe. Apparently, Apple is working with upstream suppliers to develop a retina display for its Macbook Pro products. As early as in Q2 2012, Apple will launch a new Macbook Pro with 2880 x 1800 pixels (that's more pixels than even the costliest of today's 30-inch displays can manage). More importantly, it's a return to the 16:10 aspect ratio. It will achieve this without upscaling display dimensions. Meanwhile, Apple's PC competitors ASUS and Acer plan 1920 x 1080 display notebooks around that time.

Love 'em or hate 'em, Apple has a habit of trend setting. When Apple released their original iPad, it had a meager low resolution 1024 x 768 resolution display which was scoffed at by many, yet it didn't stop it from being a runaway success. And the iPad 2 didn't improve on it, either - perhaps surprisingly, since the original formula worked so well. However, in early 2012 Apple plans to introduce its new Retina display equipped next generation iPads, offering a very high 2048 x 1536 resolution. On the 9.7" screen of an iPad, this would make the pixels all but invisible to anyone, except for those with the sharpest of 20-20 vision, giving the screen superb clarity and wow factor. These will be incorporated into its next generation iPads, which is expected to push the PC notebook market to use higher resolution displays too in order to remain competitive.
