If like me you've got a TFT monitor and you've noticed flickering on some moire images (such as the one right) or high contrast colours it may not be the monitor at fault.
The good news is there is an easy way to fix it in Windows - just change the Display Mode Timing. Usually you can find settings like these on your graphics card drivers' control panel application see the NVidia screenshot below.
Switching Auto Detect off and selecting Coordinated Video Timing should fix the problem. If that doesn't - try another mode. I have no idea if this affects game performance or even if your monitor will blow up, but it worked for my 22inch LG.
