OK. Spent the last 2 days tinkering with a new P65 in our extremely well lit living room.
First things first... great TV
I wasn't sure about going to a 65 from a 60, if I would really notice the 5 inches, but the difference is certainly appreciable! I could be content with this size.
I'll start out with the bad: the choice of finish on the screen. I'm NOT a fan and it is the only real negative I can find about the TV. Going from a Mitsubishi 1080 RP to a Panasonic ST60 to a Samsung F8000 series (all glossy TVs), I'm really struggling with this semi gloss panel. In a bright room, I would rather have the sharp reflections and rainbows versus this hard core blooming glow. At night the screen seems a "tad" more muted than I'm used to but still very nice. As an aside, my wife absolutely doesn't care..she loves the TV.
Now that the negative is out of the way..
I've been extremely lucky with this unit. No dead/stuck pixels and if there is a yellow line I can't see it. I just barely notice the dimming zones on bright backgrounds when panning.. a complete non-issue for me vs clouding/blooming/bleed on a side lit panel.
I'm using Calibrated for day and night. Backlight at 75 or 80, judder and blur at 2 each, sharpness at 20, gamma 2.2 but I've found that I like brightness at 40.
Black levels, boy oh boy does this thing have some amazing black levels! Star Wars and Pacific Rim looked fantastic. Whites are bright and crisp...way brighter than my Sammy F8000.
Colors seem very accurate... my wife has the eye for color and she prefers this TV hands down over the F8000 for colors and sharpness (using Movie on the Samsung and Warm 2).
Motion is great. I noticed a blurring/darkening on the Samsung that I do not see on the P65 when panning while gaming. Funny I didn't pay attention to that until I got this TV.
DV- I tried Pacific Rim from Vudu. The HDR is a nice but subtle effect and at this point I'm not sure if it is something Joe Sixpack will really notice.. especially if he is used to running his tv on Standard or Vivid mode (we know that so many folks do). I do appreciate what it brings to the table and I'm glad to have it. Looking forward to HDR10 as well.
Gaming- this tv is great. No blur, smooth and nice response feel. I'm happy.
Overall, I'd say you cannot go wrong with this P series! If we can sell the house in time.. I'll swap for the P75. If not, I have to decide between this 65" and the B6 OLED.. ugg.
