Your monitor is probably alright. If it was going bad, you would most likely start to see a constant black stripe on the top or sides. Some monitors naturally flicker some when playing videos, such as certain Acer flat-screen monitors.

It could be a sign that you are using the wrong refresh rate or the wrong video card driver settings. Try updating or reinstalling the video card driver (the software that runs the video card).

You could be running low in RAM or just hard drive space, so try removing unwanted programs, games, pics, videos and even documents. Then defragment the hard drive. This would more likely just address a jerky display, not actual flickering. Check that your PC's fan is not clogged with dust, to make sure the system is not overheating.

Sometimes malware (viruses and spyware) can cause video issues. For instance, one type of spyware displays a green dot in the upper left corner of the screen.

You press a button on the KVM switch (or sometimes use a particular key combination on the keyboard) to switch between computers.

What to do about flashes on my computer?

If you are epileptic try taking a break every 10 -15mins because of the rate computers flash per second. You can check how many time it flashes by the mod code. There are 'screens' that show less of how many times computers flash a second. Older CRT monitors with low refresh rates (lower than 60Hz) can be prone to flickering. You may be able to increase the refresh rate of your monitor by changing the settings on your operating system. If your CRT monitor does not support a refresh rate higher than 59Hz, you may want to consider switching to a LCD monitor which are much less prone to flickering. For a LCD monitor, some people may notice flicker on certain monitors while most other people would not. This can be hit and miss. If you experience this problem, try going to a store and testing out display LCD monitors for flicker.
