I have a new 65” Q90T and the brightness setting is not working. Everything else is adjustable but the brightness from 0 to 50 gives the exactly same picture. It’s not bad but I would like to be a little lower. Is there anyone else that have similar issue? Screen brightness is stuck at a specific level.
I found out that brightness setting is actually the backlight setting for the 2020 models. So the backlight setting doesn’t work. I can’t say for sure if it is stuck at maximum level but definitely is to bright.
