1280x768 vs 1280x720 native DLP's

I was recently informed that a 720p signal is mapped p4p (pixel for pixel) onto the 768 DLP and the extra 48 horizontal pixel-rows are usually used for a digital lens shift that doesn't affect PQ or they are just left unused.

thanks

The op didn't specify which technology dlp, lcd, etc he's asking about...but I don't believe what dicey said is the case with all 768 native pj's. At least as far as lcd pj's are concerned. My lcd plv-60 clone does not have a digital lens shift and all pixels are used regardless of source resolution. It scales ANY source resolutions such as 720p, 480p, 1080 etc. to it's 1366x768 chipset.


So without an outboard scaler/processor/htpc...no "out of the box" dvd player/source will map p2p on 768 lcd chipsets. So unless you run a video processor...your going to be dealing with the pj's onboard video processing.
