So, I understand the purpose of this thing and that it claims to reduce burn in. My question though:

Does any recommend this for HT use?
Is it a wise choice?
Has anyone had it in the past?

Hello

The purpose is to move a static image, like a map, around some so it is less likely to burn in. It is pretty much useless for movies or tv

It would work OK if you are gaming to not burn the gaming counters into the screen no?

The trouble is that if you use an image sifter (also called picture orbit by other manufacturers), the image will be incrementally moved around the screen. This prevents you from being able to optimize your projectors phosphors because if you do, when the image shifts, the corners will go off the face of the tubes. If you want to use a shifter/orbiter than you have to put the projector further back from the screen than you otherwise would have. You also have to use more overscan because if you don't, you will get a thin black bar on one or two sides at a time near the edges of the screen when the image shifts.

That said, if you know you are going to watch a lot of the same station and the station has a pronounced logo, the shifter can extend the amount of time you can view said station before the logo gets burned in.
