I have had my Samsung 52 inch LCD for about two weeks now, and I am very happy with it. I noticed some clouding when viewing a black screen--however, this clouding is not noticeable when watching an actual TV/Mobie program. I also count 2 dead pixels. Again, dont notice when watching a program. I believe under Samsung policy must have at least 10 dead pixels before they count as defective and worthy of warraty repair/replacement. The above issues are again only noticeable on close inspection, but not affecting my viewing pleasure.
Watching some regular DVD-9 films look fantastic on this machine. New releases such as Crank really show off the high res ability of this HDTV. I am expecting my Playstation 3 any day now with a bunch of Blu Ray movies and expect to be very pleased. The two HDMI inputs will be helpful as I can connect my PS3 to one while leaving my regular DVD player connected on the other HDMI.
The swinging stand is also quite handy as I can swivel the TV to either face my desk or my bed depending on where I am in my bedroom. The Sony XBR which I was also considering does not have the swivel in its stand, nor does the Sharp Aquous.
By comparison to the other LCDs, I would rate picture quality of the Samsung just a notch below the Sony (even though I understand both makers use the same LCD manufacturer). The Samsung is much better than the Sharp Aquous 52 inch I saw on display with blacker blacks and overall better, brighter color and contrast.
I am currently having a new issue with the Samsung. Ever since connecting my iPod, the TV while in Dynamic mode will constantly shift colors. Similar effect to playing a copy-protected video tape, or a PAL program on an NTSC machine. I expect there is some setting that needs to be changed. Since I do not use the Dynamic setting anyway (Movie mode is my preference), I am again not directly affected.
Overall Very satisfied.
