So as I've noted elsewhere before, WinPE for Windows 8 and 8.1 will use a display's native resolution if the hardware supports GOP in UEFI mode. Windows 10 seems to be the same way... and this WILL be a problem. Testing on a notebook with a native 4k display... installation is slightly... difficult: Picture is bad but it gets the point across. When I get hands-on with this specific system, I will get clearer pictures. *NOTE: This will be a problem for Windows 8/8.1 as well.
