Despite issues around power consumption and questions about whether 8K will actually improve user experience on mobile devices, the new Video Electronics Standards Association's Embedded DisplayPort (eDP) 1.4a will boost image quality on screens to 7680 x 4320 resolution thansk to 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.

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.
