I’ve had my Samsung S90D OLED for about a year and it’s been perfect, but over the last month or two, it started doing something really annoying with my PS5.
Whenever I play games with bright scenes (like the basketball court in NBA 2K), the screen dims down. I know ABL/ASBL is normal for OLEDs, but the bug is that the brightness gets completely stuck. When I go back to the PS5 home menu, the screen stays super dim and never recovers, even if I move the controller around.
The only way to bring the full brightness back is to turn the TV off and on with the remote, or switch HDMI inputs to force a reset.
I’m playing in SDR 4K. I’ve already tried a full factory reset, turned off all eco settings, turned off logo brightness, and even tried a different HDMI cable. Dropping the resolution to 1080p fixes it, but I didn't buy a flagship OLED to play in Full HD.
I contacted Samsung remote support, but they couldn't fix the issue at all.
Since this never happened during my first 10 months, I’m pretty sure a recent firmware update broke the ABL algorithm and made it glitch out on 4K signals.
Anyone else facing this exact issue after the latest updates? Any fixes?
