I just installed a new Radeon 3650 1GB DDR2 AGP Graphics Card. When my computer comes out of Sleep mode (Windows 7), I now notice faint horzitonal lines (one or two pixels high all the way across the screen) that kind of flickers. When I turn the monitor off/on they go away and the monitor looks good.
This is happening on my Samsung 24" (It does not happen on the second attached Dell 17" monitor) Refresh Rate 59 hertz (It allows for a 60 hertz, but everytime I select it, it switches back to 59 hertz)
Should I replaced the card with a new one?
Should I get a different card?
Should the monitor be replaced?
This was interesting. As I was typing this email it was flickering. I did not turn the monotor off/on so I could observer what was going on while I was typing. It progressively got a little worse, to a point where the white background on this page had many faint yellow boxes. Also, a small cursor started to appear on the flickering lines. Then after about 10 minutes the monitor when black for about 2 second and when it turned back on the monitor looked OK. I guess the monitor rest itself.
