I just received the newest issue of Home Theater Magazine. They did a review of the best offerings from the leading manufacturers (Samsung, Sharp, Sony, Mitsubishi, Panasonic and Pioneer) that covered multiple technologies (LCD, DLP, L-COS, and Plasma).
I can't link the review because you have to be a subscriber to get it online.
The gist of the article was this:
Plasma won the shootout by a longshot. The winner was a 768p Pioneer 5080 followed by the Panasonic TH-50PZ750U. The Pioneer was the ONLY set that was NOT 1080p to boot.
Most viewing was done from more than 6 feet and as little as 5 feet but none of the reviewers remarked about lack of detail. In fact it got high marks for resolution.
The hardest call for the reviewers was which one of the sets to rate number one. The Pioneer only edged the Panasonic because of increased contrast ratio which made the picture appear more life like and have more "pop".
All televisions were retail priced at $3,000 or as close as possible with the Pioneer being at $3,500 and the highest of them all. The review was blind with five reviewers. Blind meaning the bezels and logos were covered and all sets could be viewed at the same time. All sets were calibrated prior to the test. All noise reduction and color enhancement was turned off. Noise reduction was used in another part of the evaluation. All viewing was done at 3x-4x the screeen height. Most reviewers preferred 4x.
The finishing order:
1. Pioneer Plasma PDP-5080HD (768p)
2. Panasonic Plasma TH-50PZ750U (1080p)
3. Sony SXRD (KDS60A3000) (1080p)
4. Mitsubishi DLP (WD57833) (1080p)
5 JVC LCD LT47X898 (1080p)
6. Sharp LCD LC52D64U (1080p)
7. Samsung LED DLP HLT6187S (1080p)
The conclusion was that the LED DLP is a great Idea but needs a lot of improvement. LCD still has issues that need to be addressed. Rear pros have good picture quality but are falling back substantially and are dying. Plasma is leaps ahead of the others for straight up performance AND is a great value. Not to mention it is not all about numbers. 1080p simply does not matter if you are viewing a 50" display from 6 feet or more away if it is done right.
