HP S2031 Monitor is starting to show tracers or shadows are whatever they're called. Is this typically a monitor issue, graphics card or the VGA cable? Is there anything to fix, or do I just throw it out and get a new one? I haven't moved or connected / reconnected wires, so I wouldn't suspect that. And, I don't have another monitor handy at the moment to see if it's the card. The desktop is only a few months old, but the monitor is about 5 years old.
