Crushed blacks usually happen when the source RGB is set to full/nonstandard and the display RGB is set to limited/standard. You sure you don't have a mismatch in your RGB color ranges?

Ok I tried seeing if I could change the monitor's color space to YCbCr206 but it seems that it actually changes on its own, depending on the signal being provided, and it can't be changed manually. When the Xbox 360 was set to RGB, the color space option
in the monitor settings was set to RGB, and when the Xbox 360 was set to YCbCr206, the monitor had it set at YAC. But the lag is there nonetheless. Any other suggestions? I was thinking maybe I could adjust some option with it set to RGB to make it look like
it were set to YCbCr206, but I don't know if getting rid of the flicker can be accomplished this way.

See I’ve tested it on my old Emseron 720p TV, and no flickering happened. It seems to only happen when its on my newer Samsung TV with UHD Color (HDR10) enabled on the tv itself. Otherwise 4K UHD works fine??? My tv acts very weird with the Xbox One S

Problems with the GPU usually shows up in the form of graphical "artifacts" on screen, like weird random colors, spots, flickering, and other garbled nonsense happening. Worst case scenario, the Xbox won't display anything on the screen at all.

Either way, a defective graphics processor will require the console to be serviced or replaced.
