HDR Autoswitch causing issues on my LG OLED65C8

Thanks for that! It’s difficult to read, but I wonder whether the clock deviation of (?) 0.1% in the 420,10bit (pink) case is significant. The others are at least an order of magnitude better.

Is that information printed by the TV or the graphics card?

Olic’s is a LG.

We haven’t managed to test 422 at 2160p60Hz on LGs or Samsungs yet. I’m hoping @obstler42 will do it, but you could try the same instructions I gave him. On Nvidia at least 422 seems to be working better than 420.
