@stuckinthe90s If Mitu's suggestion to check "in emulator" or "in game" for overriding video mode settings doesnt work, I had a similar problem the other night on a Pi Zero..... i had a message floating across the screen saying something to the effect of the input signal is not compatible. I ran raspi-config and found "Display Options" then "Resolution". When i opened it was set to something in the middle of the list.... I arrowed up to the top of the list and found "Default Monitor preferred resolution". I selected that and rebooted. IDK if the Pi4 has the same config( i only have a ZERO and a 3B+... and am also quite green in the ways of Pi). That change fixed my issue. Not sure if that is the best way, and i haven't done much testing to see if there are other issues caused by that fix. Best of luck. -D
