A few weeks back I installed windows 10 on my PC. Almost immediately, I started getting problems where the monitor display suddenly changes to pink/green, changes back to normal after a few minutes, and then the cycle repeats. It seems to change most frequently in GPU-intensive tasks, eg photo editing rather than eg web browsing. This has never happened before. I switched the HDMI lead & the connecting port on the monitor to no effect. I have the latest drivers installed. Any ideas?
