DVI (Digital Video Interface) output offers a digital video signal from DVD to display without any analog conversion. The benefit of a direct digital connection is a picture free from the video noise and artifacts that are the result of D/A conversion. For digital fixed pixel projectors and TVs such as plasma, LCD, DLP, DILA and LCoS, this direct digital signal path allows a capable DVD player to select a "1:1 Pixel Mapping" DVI output resolution that can exactly match that of the display's native resolution. SOUND & VISION magazine's technical editor, David Ranada, called the resultant DVD/DVI picture quality from a Bravo D1 when displayed on a fixed pixel display "Reference-quality."
The result is that the image on the DVD is exactly transfered, pixel for pixel, from the DVD player to an 852x480 resolution display with no alteration of any kind.
There are currently only three manufacturers that provide capable DVD players: V Inc. (Bravo), SnaZio and Momitsu. You can also use an HTPC with a DVI connector and proper software.
"1:1 pixel map" if using any connection other than DVI (HDMI) and you cannot do it unless the DVD player offers a pixel-map output. 480i, 480p, 720p and 1080i will not cut it!! Neither can you do it with a 576, 720 or 1080 display (well *maybe* 576 with a PAL DVD).
