Will your computer damage a plasma TV?

While not a "sure" thing, using a plasma television as a monitor is very likely to damage the set. This is because computers often have static, or non-changing, images displayed on them (like your Taskbar or Dock). This causes burn-in when displayed for longer than 20 minutes on a plasma television.

However, using it as a display as probably acceptable if you are playing an action-packed video game or watching a movie.
