Stylus

My monitors(? BENQ GW2765HTs ) or video card(? GeForce RTX 3060) have the weirdest bug: A specific pattern of alternating #7f7f7f #000000 pixels have a green cast that becomes more pronounced the longer the horizontal run is. It's bonkers.

The monitors are attached by very reasonable lengths of cable, one is DVI and the other is DisplayPort. They're running at the displays' innate resolution, 2560x1440. The same effect happens on either monitor. It stops if I reduce the resolution to 1920x1080.

This defies everything I think I know about how digital monitors work, or else it's hitting a bug in the monitors after digital image decoding & scaling.

I've fiddled all the "picture mode" settings in the monitor to no avail.

update: I reproduced the problem with video from a Thinkpad T16 with intel gfx over HDMI, so it's in the monitor I think.

@stylus That is the strangest bug I've heard of in a long time, I would love to know what is causing it

@stylus I had a blue tinge in a game once which I thought was artistic but was fixed by a graphics driver update, but I suspect that was more the driver working around a bug in the game's shaders than anything at that level.
