I have an RTX 2080 Super founders on a TCL 6 series R635 TV. I started noticing purple flashes on the screen, generally when I moused over something that changed color, like a hover effect, a line under a HTTP link, or a menu that goes to a different color when moused over, etc. Although it also does it by itself at times. I bought this TV in early 2020, and I noticed this in 2021 or early 2022. It probably started after an update of some form either a TV Firmware update or a driver update. I went into the Nvidia control panel and while messing around, I changed the resolution from RGB to YCBCR 4:2:2 at 10 bit, and the flashing was gone. I tried different YCBCR settings and the flashing was still gone. I tried RGB, and again same issue. I have reset the TV and PC, still the same issue. I have swapped out cables. I now have a 2.1 Ultra High-Speed cable that has the certification sticker/hologram that you can scan with the HDMI app, and it is a certified 48 gbps cable, not that my TV can support that, but it is still a certified cable. I still have the issue in RGB mode.
I have seen other that have this issue, so in the interim, switching to YCbCr in Nvidia Control Panel, under Resolution fixes it. I think YcbCr 422 provides better color and brightness. However, in long term, I think RGB can be a better format, especially for HDR. So, anyone have any idea what is actually going on?
