At the WinHEC conference Microsoft revealed that Windows 10 will support 8K (7680*4320) resolution for monitors, which is unlikely show up on the market this year or next.
It also showed off minimum and maximum resolutions supported by its upcoming Windows 10. It looks like the new operating system will support 6"+ phone and tablet screens with up to 4K (3840*2160) resolution, 8"+ PC displays with up to 4K resolution and 27"+ monitors with 8K (7680*4320) resolution.
To put this in some perspective, the boffins at the NHK (Nippon H?s? Ky?kai, Japan Broadcasting Corp.) think that 8K ultra-high-definition television format will be the last 2D format as the 7680*4320 resolution (and similar resolution) is the highest 2D resolution that the human eye can process.
This means that 8K and similar resolutions will stay around for a long time and it makes sense to add their support to hardware and software.
NHK is already testing broadcasting in 8K ultra-high-definition resolutions, VESA has ratified DisplayPort and embedded DisplayPort standards to connect monitors with up to 8K resolution to graphics adapters and a number of upcoming games will be equipped for textures for 8K UHD displays.
However monitors that support 8K will not be around for some time because display makers will have to produce new types of panels for them.
Redmond will be ready for the advanced UHD monitors well before they hit the market. Many have criticized Microsoft for poor support of 4K UHD resolutions in Windows 8.
