Hi everyone actually I have the same problem but in MSFS when using F-117 for night flight it's so foggy that its blurred all the light on the horizon, far away night light was gone. Not sure on Ctrl-Q but in my Pimax apps there is a setting for Local Dimming with off, xxxx, Highlight and Extreme but seems not helping much.
Not sure on the firmware or apps version but check update its the latest Pimax apps
Still want to try different setup again though to ensure issues not coming from my own setup
