Ummm, well, I think there is some confusion here about degaussing monitors. You degauss CRT monitors, NOT LCD monitors. You degauss a monitor to clear the electromagnetic forces buildup in the screen caused by the high
voltages present with CRTs. These unwanted magnetic forces can alter the magnetic fields used for targeting, changing the trajectory of the color beams as they are fired from the guns at the phosphors on the back side of the vacuum tube, distorting
the picture. For MANY, MANY years, you have not had to manually degauss a CRT screen because most monitors do it automatically when powered up, as characterized by a distinctive "bwoing" sound. You typically would only need to degauss CRT monitors when left on for extended periods of time.
LCD and Plasma monitors do NOT use high voltages, magnetic fields, color guns, or particle beams fired through a tube. Therefore, they NEVER become charged with excessive electromagnetic forces, therefore, LCD monitors NEVER need degaussing
I have never heard of putting one CRT in front of the other. In the old days when we degaussed radar screens, we had to "isolate" the monitors to prevent the magnetic field from one monitor impressing (dumping or collapsing) onto another monitor. Putting one in front of the other may cause the field from one to dump on the other, but at best, they would simply equalize, and not be dissipated completely.
Since Immortal indicated in his first post he has a Samsung SyncMaster 220WM, a LCD monitor, he has nothing to degauss.
The problem is either with the monitor, or the card (or on-board graphics) - assuming all cables and cards are securely fastened, including any detachable cables on the back of the monitor. As Abydos suggested, I would try another monitor on that computer, or that monitor on another computer. If the problem stays with your computer, you know it is probably the graphics card (or motherboard, if on-board). If the problem follows the monitor to the new computer, you know it it the monitor.
