Solution: This issue may be because of the unstable connection between the KVM switch and the monitor. Check your cables to see if there is any faulty one, and make sure they are not loose and are all well plugged into the port. However, while these devices can streamline workflows and reduce desk clutter, users sometimes report video artifacts or screen distortions when using a KVM switch. It's a marvel of efficiency, a bastion against desk clutter. For instance, when you try to handshake with your monitor, your graphics driver can just give up after a while. How to power cycle: Unplug everything.
