Are there any commands out there that will tell me something like:
Current display mode: 3840x2160, 120Hz, 10-bit, YCbCr422 (DSC unsupported) Available display modes: * 3840x2160, 120Hz, 8-bit, RGB444 * 3840x2160, 120Hz, 8-bit, YCbCr444 * 3840x2160, 60Hz, 10-bit, RGB444 * etc. Everything I've seen so far is missing information on bitrate, chroma subsampling, and DSC status.
