Both, in this case it was in-game Kingdom Come: Deliverance as well as just on the PS4 Pro dashboard. My backlight setting is 20 (maxed).
Why are you watching anything in standard mode? Just use movie or game mode. That's it.
Yeah, even Dynamic doesn't have the issue, guess I'll just stay away from Standard entirely. What's odd is I can't set it to Game mode, apparently because my input is PC and not Game Console? I have every input going to my AV receiver then over HDMI 4 to my TV so maybe that is getting in the way?
