    Right now when we convert Video or slideshows we compensate for the safe area(about 10%) which is for overscan on normal TV sets.

    My question is this:

    Do the new LCD and Plasma screens overscan like there older cousins or are they like PC monitors with no overscanning.

    This is important to me as I am planning to switch over to one of these and I want to convert with this in mind..

    Thanks in adance.

    All published information about overscan with TFT, LCD and Plasma screens are that there is NO overscan on these screens. My understanding about overscan in regard to CRT (TV sets and PC monitors) IS. PC monitors do not have overscanning because you can control what is and is not hidden behind the case bezel. TV sets generally do not have these type of overscan control built into the chipsets and because most US NTSC TV sets that are 4x3 ratio have only one resolution (640x480) not like a multiscan computer monitor with 640x480, 800x600, 1024x768 and up.

    Hopefully someone out in the forum can expand on this explanation.

    Overall, by nature, those screens don't have any overscan areas.

    In practice, when LCD/TFT screen has a tuner, a special proccessing is always done before the picture shows to screen. So, the manufactures have their practical solutions for problems

    If now the LCD/TFT screen is a typical PC monitor like (those are cheaper so more popular) then don't expect those fuctions. In this case, using a PC with programs like dscaler etc, you can eliminate such issues with amazing results.

    Finally, you can always zoom a bit any source, to create a fake "overscan" yourself, if this is such an issue.

    To tell you the true, because I'm having years now the same concern like you, when I encode, I always crop the black lines of the overscan area, center the best possible any picture and encode letterbox-like all my material. That way I feel that at least my materia gonna be always in the center of any screen in the future, a good start....
