----- HDTV Magazine Tips List -----
Rodolfo,
Based on your answer, 1080p must be displayed at 60fps. If it isn't then
the picture would have artifacts. Or if 30fps it must be doubled or in the
case of 24fps it must be tripled. Bottom line, if the television does not
accept 1080p at 60fps one should avoid it if looking for perfection.
Regards,
Hugh
