No A/D conversion with DVI. Even with VGA, the TV has to perform analog to digital conversion. With DVI it's pure digital and you get the best color fidelity. That's the way it looks to me eyes anyway. And yes, I did notice a marked improvement in PQ via DVI (from my PC) versus component and even VGA.
It may depend somewhat on your input device though. Some STBs may do DVI/HDMI well, and others may not. As mentioned before, the Samsung HD950 up-converting player was a major disappointment to me via DVI. My PC looked alot
better. Maybe the Toshiba does a little better job though. If it has a 768p mode, that might worth trying too. 768p modes seemed to work best for me because they match the TV's vertical resolution.
Since these Westy displays went back on sale, I went back and looked at em again. This time BB had all their LCDs connected to a component 1080i feed which made comparisons easier.
There did seem to be some visible motion artifacting/lag with interlaced signals via the component input. I noticed the same type of motion artifacts with the 1080i feed that I saw with a 480i component input from my DVD player. So in general, I'd recommend progressive modes (480p, 720p) via component. If the lag/artifacts are related to de-interlacing, then DVI may have the same issues with 1080i as well. If you notice any choppiness or artifacting with 1080i via DVI, then I'd also recommend trying progressive modes there as well if you can (768p, 720p or whatever's handy). FWIW, I did not notice this lag with 480i via composite or Y/C, but the overall PQ was inferior with those.
AFAIK, all the units I've looked at have had the 1-25-2005/0.37 firmware. So I'd be sort of curious to know if users with different firmware have noticed this as well.
