      Hi when I use A-LM 540p_CRT (Line Drop) via HDMI on my HD CRT Colors look wrong as if the OSSC Pro is outputting in REC601… reds look kind of Orangish or yellowish well at least compared with A-LM 1080i (Line Drop)

      If someone can look into this issue if it’s a firmware bug and figure out if it’s fixable I would appreciate it

      thanks in advance

        The component output is currently always using Rec709 primaries in the CSC. Perhaps your TV is expecting Rec601 with 540p?

          This particular color issue is A-LM 1920x540p via HDMI not component

            Is TX mode set to HDMI-RGB? In that case there is no CSC on output path so the discoloring would be due to TVs processing.
