Windows 10 to support 8K video resolution:
"Microsoft is looking beyond 4K with Windows 10 and bringing 8K support to the OS, years before TVs, monitors and content for that display resolution become widely available.
The 8K support for Windows 10 will be for displays larger than 27 inches, according to a slide presented at Microsofts WinHEC trade show in Shenzhen, China, last week."
