ABL exists for a reason. Not sure why people tend to mess around with those settings. It will definitely void you warranty but above all the burn in
protection might be compromised.
I'm well aware. But I'd also be potentially willing to risk it if what that guy said was true and you can change the strength of ABL without having to turn it off completely. As is, it defeats the purpose of HDR1000 mode for me personally as the ABL is not tuned well enough to not be distracting and I'm not gonna be switching back and forth depending on the game heh. So I just leave it on TB400 now.
I never really noticed it in my LG OLEDs whether it's because it maxes out at in the mid 700s peak brightness or because whatever algorithm LG uses isn't as sudden and instant to change back and forth as the AW does.
I wonder if it's something Dell can tune with firmware.
