Thanks guys.
orogogus, my video card from the HTPC made a huge impact in PQ and ability to resolve details in the dark scenes. So far I've been getting awesome results on both sets when viewing SD DVD movies and if you see some of the pics directly comparing two TVs viewing Star Wars you'll see how impressive the 7UY performs it's almost dead equal to the 9UK.
I currently do not have the HD-DVD player as I've been waiting to get the HD-DVD PC Drive, but I've got plenty(aweful a lot) of Japanese HDs.
The nVidia graphics from the notebook gave me similar issue with image *noise* in pretty much any type of video and color levels. But it was gone *completely* after switching to the new HTPC w/ ATi x1950XTX card. I also had no picture noise issue when I used to run it through my old ATi x800XT card, very good at noise reduction. But this new card has virtually no noise.
JoonTV, the Pio 5070's are very nice TVs. I was *this* close to buying the Pio Elite 1140HD. I am envy to have that set.
RichB, thanks for the comment.

Though in real viewing experience I still love the way 7UY displays images. The color tones it generates really attracts me, though I also am very impressed with the 9UK's strength in better detail and color textures. In some of the videos I view, there's something that 7UY has, makes the images look more pleasing to my eyes. But in some other videos I like the 9UK better. Basically I'm happy to have both TVs. I need both of them.
Rich, you know, before I bought the x1950xtx I thought it was not going to provide me 1366x768 via DVI but it certainly gives me a perfect 1366x768 1:1 pixel mapping. The texts are unreal, razor sharp, very clean, and perfectly even across the screen. It looks even better than viewing on my Sony CRT monitor and a little LCD monitor. This card is also providing 1366x768 on my 7UY using SVGA cable. I was surprised on that, too. Yes it must be the late model ATi card offering such nice resolution. All the 7UY pics you're seeing is with the SVGA cable.
