Just purchased a PN50B450 yesterday.
Just wanted to tell you my story.
This is my fifth HDTV this year and I have some things to say that you may find interesting.
The first tv I bought was a Samsung HL67A750 LED DLP . It had a VERY nice picture on it and was my first experience with HD.
I ended up buying a used Vizio p50hdtv10a PLASMA for my bedroom because going from 67 inches in the living room to a 19 inch crt at bedtime sucked ..lol
Well, after watching the plasma in the bedroom with its sharper images and excellent screen uniformity, I started to become unhappy with the DLP set.
SO , I put the DLP up for sale, got $100 more than I originally paid for it, and went and bought a PN58B550 plasma.
Had the B550 for a couple weeks and became unhappy because of pink hue issues and it didnt seem as sharp as the 50" vizio.
So , I took it back and got a Panasonic TH-58PZ800U.
I used service menu offsets provided in the owners thread for the 800U but after 2 months, I could NEVER get a picture I was happy with.
I also think that maybe Plasma is better suited at 50" or under because it didnt seem very sharp either..like it always lacked a tad bit more focus.
(By the way, I have a PS3 for bluray).
Finally got fed up with the Panasonic 800U, sold it on craigslist at a loss of $400, bought the PN50B450 and brought it home.
Heres my findings about the TV's i've had so far:
Samsung HL67A750: Great pic if you dont move your head up or down or sideways when viewing...or if you lay down on the couch to watch tv, the screen goes dim at the top.
Samsung PN58B550: They STILL didnt fix the pink hue??????
Still, a great picture on it, excellent colors and blacks were on par with the Panasonic 800U IMO. however, the "soft" image of what I percieve to be a deficiency in plasmas over 50" was annoying.
Panasonic 58PZ800U = CRAP! THX Mode = DIM even with service menu adjustments. Colors just never popped and had a dull, lifeless picture on it.
Blacks, IMO, were NO BETTER than the Samsung B550.
Like the B550, picture seemed soft.
Samsung PN50B450 = I'm finally a happy camper. I wish the screen could be bigger but I wont go there with plasma (over 50") anymore.
It is SOOOO nice to see good colors again in my living room.
I cant tell one bit of difference between this and 1080p sets as far as resolution goes. It actually even looks sharper.
I'm using an average of the common setting in this thread (my Movie, warm2 mode looks good, not red like others have reported)
With that said, here's what you might find surprising:
The VIZIO P50HDTV10A in my bedroom, bought from craigslist for $500, with the red snow storm issue (which I took care of myself by adjusting voltage to potentiometers on the video boards) has, by FAR, the BEST LOOKING PICTURE of all of the tv's I have owned so far.
The HD pictures from my STB are just amazing and even 3D looking and the colors are completely satisfying - I adjusted the colors and picture settings to my liking when I first got it and I NEVER EVER -NOT EVEN ONCE have changed a setting on it since - and I am very picky.
It just sucks knowing that i will eventually get the "Pop of Death" that these particular models suffer from and it will be gone
And SD tv, looks better than on any other HDTV I've had too.
Black levels, to these eyes seem to me to be on par with everything else I've owned.
So, its the Cheap Vizio, with the B450 coming in at a close 2nd.
YEP, 2 720p sets, bottom of the line, entry level plasmas, have better, sharper, crisper images with more pleasant colors than the much heralded 1080p Panasonic 58" 800U or the 58" B550..and cost me a thousand and change LESS.
