New standard paves way for 8K display in all-in-ones, laptops

Displays based on VESA's new Embedded DisplayPort (eDP) 1.4a standard will reach PCs, mobile devices by 2016

A new standard that supports higher-resolution displays should help move 8K screens from the realm of high-end TV and into laptops, all-in-one PCs and possibly even mobile devices.

The Video Electronics Standards Association's Embedded DisplayPort (eDP) 1.4a will boost image quality on screens through faster video transfer rates. The newer standard is for displays inside computers, and it will replace the older 1.4 standard that was released in early 2013. With 8K, displays will show images at a 7680 x 4320 resolution.

Displays based on the new technology will start appearing in computers and mobile devices by 2016, VESA said.

Screens with 8K resolution could find their way into high-end laptops and all-in-one desktops. Apple has used a modified version of the eDP standard in its iMac with 5K Display. Some high-end gaming and business laptops already have 4K displays.

At the moment, 8K resolution is the province of high-end TVs. Japan's NHK is testing 8K broadcasts in time for the 2020 Olympics, which will be held in Tokyo.

Tablets and smartphones don't have 4K screens yet, and may not get 8K screens. It's hard to differentiate pixels on small screens, and 8K screens could be expensive for device makers. For now, mobile devices have powerful graphics processors that are able to process 4K video, which can then be shown on external displays.

Displays are the most power-hungry components in laptops and mobile devices. But the new eDP standard could improve battery life by reducing display circuitry and improving processing of pixels. For example, the new standard will allow a graphics processor to refresh pixels in only parts of the screen, as opposed to over the entire screen as is the case currently.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
