In Reply to: DVI Better Than Component Video? posted by Dave Nole on December 30, 2003 at 12:59:14:
Done correctly, a DVI output from a digital source gives you the capability to go from a digital signal (compressed YCbCr via MPEG2) to uncompressed digital RGB at the DVI output directly to the digital RGB processor in the display without any analog processing, extra D/A - A/D conversions and associated cables in between.Unfortunately, some display manufacturers route their display's DVI input to an analog processor, thus negating much of the above. Many people who have compared their display's component picture vs the DVI picture have come away with the impression that DVI was no big deal. In reality, they were ignorant of the fact that the display manufacturer deliberately limited the DVI input's capability by their lack of proper implementation of the format.
Many, but not all, rear projection CRT and LCD manufacturers are guilty of this.

I would suggest a trip on over to AVS Forum for discussions on Sony's implementation of the DVI format in their displays, as I do not know about specific models. Be warned: there's a ton of information available and you may not find the answer right away.Here's the RPTV section (CRT, DLP and LCD):

It's awesome! The DVI is WAY WAY better than the component connection. The $200 Bravo D-1 outperforms my Sony S7000 and my Sony S700 (I think that is the model #) and my other DVD players by a BIG margin using the DVI connector. Of course, all the other players have a better component out than the Bravo.
Do you know if the Sony KP65WS510 RPTV does the DVI to Analog thing or does Sony do it right?
Mr. Murphy,
You said, "some display manufacturers route their display's DVI input to an analog processor." Do you know if the Sony KF-50WE610 have this 'defect'? How can I find out? If so, then I wonder if it is worth the expense of getting a DVD player and sat. receiver with DVI outputs.

David
