All AI stuff off, game optimised mode on my desktop pc seems fine. I've been watching a few seasons of always sunny on netflix in a window and that seems fine. What are you watching specifically where I can check out this black crushing?
edit: does disabling TPC help you @R3X Also is your hdmi set to full instead of limited when using a PC?
Black crushing occurs in dark scenes, so really does depend what you are watching. Movies and Tv series set in dark or midnight scenes would reveal it within seconds. Be it Batman films or Halo tv series, batwomen tv series triggers it within any dark scene which is there most of the time. A lot has to do with your settings though if you watch in day time mainly and have standard picture mode on or isf bright defaults on you won't notice it as much, actually might not notice it at all if you are watching bbc news and Friends tv series, but if you watch during night time when its dark with filmmaker mode or isf dark accurate modes and OLED light 35-45 (which is what is recommended) then you will see it. Using brighter TV modes or settings in night viewing can help... but it won't ever look right and will be overbearing and bad for eyes.
Yes matched video range both ends so they are correct, Auto on the TV so far has matched source or other end perfectly but I have tested it limited to limited and high to high with same results. Raised whites or glowing black bars would show a wrong video range within seconds too.
This guy shows the "black level upping" fix, but then mentions the pixels coming on think he meant pixilation fault, pixel flashing etc which is the inaccuracies in this temp quick fix.
Another one that discusses it briefly, mentions blacks turning grey (inaccurate):
This calibrator released a good video and alternative fix, but I call it Alternative since you end up pushing colours and contrast incorrectly in other scenes, he also recommends proper calibration as the proper long term fix.
Basically no quick fixes, TV calibration is the proper fix its even what my tv calibrator said.
