I have a Samsung SyncMaster 191n. When I turn the PC on the screen may show okay for a minute but then it starts dropping out the black colors in the picture. Example: When the Win XP screen saver comes on that usually has a black background, it is white but the XP and Windows logo is ok.
I did that and swapped cables and connected it to a Laptop port, and I still had the same issue. I left it on for several hours and now it seems fine. Maybe fluorescent back-light power supply was not providing enough power. Well thanks for the reply I will see how it goes
