I’m trying to use a 40" Vizio 4K TV as a computer monitor, with this setup.
CentOS (actually Scientific) Linux 7
RTX 2080 Ti, HDMI port.
NVidia drivers version 440.44
HDMI cable is rated “Premium High Speed HDMI.” I have gotten this cable to negotiate 4k60/444.
- Picture mode “Computer”
- Color Space “Auto”
- Input Settings->Full UHD Color “On”
This image seems to be the go-to test for chroma subsampling. The bottom two lines are garbled at 100%.
The OS Settings->Devices->Displays shows 3840x2160/59.94 Hz.
The nvidia-settings GUI shows 3840x2160/60Hz.
But the video display still has compressed chroma.
I was able to force a different NVidia card to YCbCr444 with full dynamic range using the Windows NVidia control panel. Perhaps that solution is available to me here.
