I don’t play games on mine but got the burn waiting for panel replacements to start up again.are you saying less than 50 brightness will help ?. Does that mean higher oled light or contrast?.
You'd adjust OLED light to reduce the brightness to half. It's just the one channel that gave you problems - so if you're going to continue watching it you should do so at half of your usual brightness even (so half of the half you're already at). That way it will take 8 years instead of 4 to burn in again. You can probably make a dimmer picture mode to use only when you're watching that channel. The best thing to do to avoid burn in would be to not watch that channel anymore, but if you can't do that just remember the rule that every time you halve the brightness you double the lifespan.
Your burn in could have started a while before 4 years, like at 2.5. So halving your usual brightness of that channel might only give you 5 years.
Just watch that channel verrrry dimly lol
