Thankyou for the reply, although I can't see anything that may help.
For info l, have sat here for days on end installing, updating then reinstalling copious amounts of drivers to troubleshoot this issue, I can deduce with almost certainty that amd have removed something from there drivers post SEP last year that allows 100-120hz gaming , HDR and 1440p support to this panel this panel.
although the most frustrating thing is that I they have also withdrawn 1440p support for the RX5700xt post Jan 23 editions. I can install all versions of drivers then do a clean install of 22.8.1 and everything works fine from a refresh rate, resolution perspective, although I get some instability in games such as witcher 3 and Hogwarts etc
Would be great firbthe AMD driver to to fix this issue or reply as to why newer driver have removed standard features that obviously were there in older drivers iterations.
I have read NVIDIA cards do not have any issues with PC gaming on TV OLED panels.
cheers
