[AG-TECH] PIG Specifications

[Jonas Talandis]

Burn-in is a potential problem with any plasma. It's best to avoid static 
images and vary your window positions. The newer displays use some pixel 
orbiting and screen saver techniques to help deal but not eliminate the 
issue. I've also heard that plasmas have a half-life of sorts, that the 
image degrades over time, though haven't experienced that.
