      What is the output range of the RetroTink2x, is it Limited 16-235 (Video standard) or Full range 0-255 (PC standard)?
      Is the HDMI output in RGB or YCbCr format?
      If it is in YCbCr, is it 4:4:4 or 4:2:2 at output?

        From the data sheet:

        All ADV728x devices (MIPI CSI-2 or TTL output models) output video data in YCbCr 4:2:2 format.
The video timing is compliant with the ITU-R BT.656-3 or ITU-R BT.656-4 standards.

          Yes, that’s the input to the HDMI chip, the output from the HDMI chip may be something different than the input from the ADV7280.
          The OSSC for example is RGB Full Range 0-255, the RT2x might be something else.

          I assume it is the same as the 7280 output, 4:2:2 limited range.
