Hello everyone, I have
the following problem: I have a PC with two graphics cards and Ubuntu 15.10 on board. Video cards are used to run CUDA code. At the same time, regardless of which card I started on, ripples appear on the screen, noticeable only on a uniform dark background. Does anyone know how to deal with this?

try another monitor, there is a chance that the PSU of the monitor is junk

watch the frequency of the video card, maybe it throttles? Maybe the power supply is failing?
