White lines running horizontal. The screen shot does not capture the lines. I tried a digital camera and it's not very clear either. The areas in the circles were horizontal lines.
Is this a failing monitor or?
When I started typing the question there was scattered white lines or thin white areas running horizontal on the desktop.
Now they are gone. The computer has not been turned off and on, so the issue does not appear to be happening at boot and then after the system or monitor warms up the lines disappear. These lines are never vertical.
