I've read a few peoples comments regarding how static images can ruin a plasma, but what's the official line on this? How long must an image be displayed before it causes a problem? For example, if I decide to use my plasma with the pc (which it was designed for) and spend a lot of time using Internet Explorer/Netscape etc, should I be concerned that the window frame and buttons will cause permanent damage if used for say, 4 hours a day? And why would watching sky cause a problem? Is the problem confined to Plasma, or is it the same with rear projection, front projection etc etc. Cheers all, Phil.
