I find that Color Setting for 4K 50~60Hz has issues as well. I have selected "YUV422 12Bit", but I only get the worst "YUV420 8Bit" when playing a 60Hz 4K video. I think the firmware has big problem for 4K color setting. It seems that the color setting for 1080P video is OK. Could you fix it ASAP? Thanks
Please see my reply to your other post. This means your display is not capable of 12-bit 4:2:2 at 60Hz. Can you post your EDID: To Download EDID ================ Settings/Display/Custom EDID/Save EDID Save to a USB stick or network location.
