Ok, finally got to see the 50PZ800U at BB. Thought they would never unbox the darn things and plug them in.
Sound System: Seemed excellent to me. It might be better than any others currently on the market for flat panel. Crystal clear and very defined voices and music. Yes it might be better than 700/750.
CATs: On this one, it seemed to work perfect - BB let me use a flash light. It would automatically, adjust the picture in about 15 seconds, very gradually. This should work real good in a home setting.
PQ: Well in the store there is no difference between the 85U or 800U, which is fine with me because the I consider the 85U a perfect picture. BB feed is via antenna; inside BB RF feed loop - not antenna to the world. While it created a source signal of 1080i the actual program material was fairly low quality, it was not real 1080i material.
Directly above the 800U on the wall was the LG PG20; when both pictures set to vivid or standard, they looked about 98% the same. Again that is due to the low quality BB feed (typical). It does make you stop and think: LG about $1,200 and the 800U $3,195. Both these sets face directly to bright outside direct sunlight - facing south in Texas, you can only imagine. Still, in vivid the 800U was brighter and more vivid (in vivid) than any of the LCDs there (for those that like their TV bleeding). THX mode would be like the 85U cinema with the picture control reduced, brightness reduced, and color reducedbut we all know that, it was an excellent picture - even with the low quality source.
The Trim: Well, it is ok, I can live with it, but they should have done better.
The Glass: As you know with almost all plasmas there is a ghost if you are sitting to the side. Put on the menu screen and you can read two sets of letters.
That ghost was there on the 85U but it never bothered us. My concern was, is there even more ghost on the 800U? I don't think so? I did study the menus on both 85U and 800U for about 15 minutes. Yes there was some difference; but I believe the ghost are 98% the same, and therefore not an issue for us.
85U ghost: Put on a menu screen (i.e. one with the word return and the remote control circle is a good one to use). Then put your knuckle on the screen (in front of the word return). You will notice that the real image is at one place, your knuckle is about ½ outside of the real image, but the ghost is about ¾ behind the real image.
800U ghost: Maybe the spacing between real image, knuckle, and ghost is just a tad wider? I do not know if that has any effect on PQ or not? I don't think it does. In order for me to tell if it does would probably take a couple of hours or more in the home setting. So I think ghost, as such, is a non-issue. But other opinions on this subject are welcome.
Overall, I liked the set a lot. Sure wish they had the PG60 right next to it!
