    Am I correct in thinking that both DLP and LCD RPTV's are immune to burn in, and have perfect geometry?

    Greetings

    That's generally the case for burn in ... but perfect geometry is another matter. It may be perfect ... but off center ... or overscanning too much or the panels might be misaligned and you see small color shadows.

    Regards

    There are still problems with lenses and mirrors. When the sets get thin, the throw gets short and the lens has to go to a wider angle which gnerally have more distortion (remember the wide-angle fish eye lens?).

    There can also be problems that you don't notice in 16:9 but see in a 3:4 panel display where there may be a bow in the edges due to lens pincushion which is non-correctable.

    However convergence is generally a lot better and more stable than the CRT projector.

    Thanks for the replies, folks. More info to chew on.
