I have Acer Predator XB271HK working with NVidia GTX 1060 videocard on Windows 10 x64. As noted on monitor's page, it has capability to display 30-bits color (1.07 Billion Colors, 10-bits per color channel). But I can't set this mode.
I talked to Microsoft support to make sure that Windows 10 has no any limitations on this parameter. They reported no limitations.
I talked to NVidia support to make sure my videocard can output 30-bits color. They said that with latest NVidia Studio drivers everything should work fine.
NVidia support recommended my to query Acer support to make sure the monitor actually can display 30-bits color.
I digged a little bit deeper and find that each modern monitor has built-in memory with information for videocard and OS called EDID. I found an application that can read monitor's EDID and find out that my monitor reports only 8 bits per color capability.
Do I have broken monitor or Acer posted wrong information in monitor's Technical Information page?
