Question : Problem: Transparent Screen Saver to protect LCD TV

Hi,

I've got a large LCD TV which is shortly about to be used as a monitoring station (i.e. it'll have a number of system health monitoring apps open on it).
It's essentially not going to change throughout the day, but is going to be left on continuously for around 8 hours a day.

Now, I'm not sure how resilient modern LCD TVs are regarding screen burn, but I'm a bit wary that having near-static/rarely changing images on a 42inch tv all day is going to wreck it.

I seem to recall that windows 98 (with the Plus! add-ins) had a screen saver which still displayed the desktop, but was a clear ball "underneath" the desktop which moved around. It's hard to describe!

Essentially, I just need a screen-saver that still displays the contents of the computer (and obviously still updates!) but changes the pixels enough not to cause a permanent screen burn.

Any ideas??

Even if a wiki article claims that it happens, I would not put my trust in it.  LCDs use a completely different technology than plasma or CRTs, which are susceptible to burn-in.  An LCD pixel is a transistor that modifies the amount of light passing through it, and whether it is in the same state or not for long periods of time should not affect it.  What LCDs are susceptible to is stuck pixels, where the pixel no longer responds to change commands, but that is not caused by static images.  If you see an image on an LCD that seems like burn-in, that is likely persistence, which can be fixed easily by changing the image, and even stuck pixels can sometimes be fixed this way.
