Re: OLED burn in/image retention due to HUD. Busy HUD
I have game mode (low latency) on all the time, and I even run the screen in dark room mode (ISF) because it's more accurate colors and it's also dimmer for the dark room/theater experience I go for, so that should actually be very gentle on the screen compared to * settings like vivid. I use the screen refresher frequently to reduce how long it takes to get rid of the image retention.
We aren't leaving the game on some menu or anything, it is just the fact that the HUD has so much pure, opaque white elements right up against opaque black elements that are always static (no HUD sway or dimming, etc) that it causes image retention very quickly when you play for several hours every day. It shows up in about 2 weeks and then takes a week or so of not playing Apex to get it to go away.
I exclusively game on my TV and this is the first game to have an issue like this.
