    My projector is native 4 x 3, but like many, is switchable to 16 x 9 to take advantage of anamorphic DVDs. My question is, can an LCD panel suffer any kind of permanent "burn in"? Most of the time I leave the projector in 16 x 9 mode but when I switch back to 4 x 3 a very faint thin blue line extending half way across the screen becomes visible about where the 16 x 9 screen used to end. It's really only visible when colours are lightly saturated and only the upper half of the display seems to be affected.

    LCDs and DLPs do not burn in like CRT displays.

    I've heard LCDs can exhibit a form of "burn in" but it's temporary. It should fade with continued use in 4:3 mode. Also, it's possible that when a portion of a LCD panel is kept "black" for extended periods it could heat up more than the rest of the panel (as it has to absorb the energy instead of passing it to the screen), causing a shift in the color. Once again, this should fade if you keep it in 4:3 mode for a while.
