Flickering horizontal lines across monitor occurs periodically throughout the day.
I have a new HP Pavilion 32 inch monitor. Periodically throughout the day I have flickering horizontal lines across the screen. This is very irritating and makes the monitor unusable. For reasons to complicated to explain, I am sure it is NOT a problem with the monitor or my computer. I am sure it is a network signal problem. What is the solution to my problem? I have tried resetting the modem several times but that doesn't help.
