Green static like lines, sometimes horizontal other times circular, appear on screen when and whenever the screen is black! A color screen is not effected. Thus, at the top of my screen, I now see a green flashing broken line running just below Experts Exchange horizontally across the top of my screen! The monitor is a Samsung 24", 2 years old!
I have connected 2 other monitors, a Dell and a smaller Samsung, to the same connection at the same location and no problems.
So the problem lies with the 24" monitor? Right?
But... I have also moved this monitor to another location on another computer and again NO problem. No Green lines!
I have a Mac Pro with dual boot via Bootcamp and the green lines appear on both the Windows 7 and Snow Leopard sides.
I can't figure out what it is... unless this particular monitor is susceptible to some interfering signals the other 2 are not. But one of them is a nearly identical Samsung, simply smaller!
