Windows has done something, everything looks browner/redder
Not a gradual over time thing, it was like a flick of a switch. something just changed.
I'll hook the xbox up later to see if my TV is failing, but this looks a LOT like windows nightlight mode, where they "reduce" blue light.
But I checked, and that isn't currently enabled.
I do know that the blue part of a display burns out fastest
I don't actually know the first thing about color calibration, but everything appears to be set to "default"
It was the driver. It poo the bed and the display looks fine now. Audio is disabled though because AMD/ATI suck a fat one.
