    Hey all,

    I know that laptops can suffer from dead pixels, and they have programs that flash different colors full screen to make detecting them easier...

    Now, what is a good way to check for burn in on HD !6:9 sets?

    Also, If i am not mistaken, there can be a form of "dead pixels" in rear projection tv's as well, right? what would help for this?

    Thanks,

    Matt

    CRT-based rear projection TVs don't have pixels - LCD and DLP-based rear projection TVs do, as do plasma sets.

    To be more precise, LCD and Plasma sets can suffer from "dead pixels" while DLP sets actually suffer from stuck mirrors on the DMD chip. In each of these cases, there's nothing that can be done to repair it, and there's really no way to "prevent" it from happening in the first place. It's an unfortunate risk inherent to each technology.

    As far as checking for burn-in on CRT or plasma-based sets, I suppose it would be easiest to see against a solid color image, but burn-in isn't much of an issue if you properly set up your set.
