My sister was given one of these recently and I started wondering about image burn-in. I've always read mixed answers on whether LCD screens can be susceptible to that. It would be sorta funny, but not entirely surprising, if these can suffer from image burn-in.
Do the manuals for them have any warnings about that? Has anyone, who has had one displaying one image for an extended period of time (maybe a couple months), noticed a problem?
I know the typical use probably involves rotating through images in a sort of slide show, but some people might be using them to show one image until they get tired of that image, then they switch.
