I had a "new" friend stop in:

I was impressed with the new Sammy's thin profile and high tech design, but of course I was most interested to see it's best performance and compare it to a calibrated Panasonic 800u THX plasma, which I am very familiar with.

First impressions before I did anything to it:
Brightness uniformity was good on a white field, with just a slight darkening at each of the 4 corners. This is not much different than other LCDs I've calibrated.
Color washed out off axis as on other LCD displays, with red becoming a little orangish and green a little yellowish off to the sides.
Black uniformity was not that great; it had some blotchiness and cloudiness in some areas.
Attachment #1 is the measured performance in std mode before cal, at default settings.
I started by going into the service menu and calibrating and unlocking the calibration day and night modes, but then I noticed that they had much higher black levels than other modes like Movie mode. Even though this is not a local dimming backlight model, it does dynamically dim the backlight with low APL signals in all modes except the calibration day and night modes. I thought the much improved blacks were too valuable to sacrifice, so I decided to concentrate on calibrating movie mode. Attachment #2 is uncalibrated Movie mode. The blacks went from typical LCD quality to, IMO, 8G Kuro quality. The cloudy spots were much less apparent and no longer a problem in most situations.
Movie mode calibrated well in the user menu. Grayscale tracking was good though not exceptional; on par with other Samsung LCDs. Gamma started high on the low end because it came out of black slow like a CRT, but it averaged about 2.15 the rest of the way. I could have made it over 2.2 the entire way, but then it would have been even higher at the low and and shadow detail would have been very hard to see. The color gamut calibrated nearly perfectly! The only 2 colors with dE higher than .5 were red and blue, and they were both not bad. Color luminance was exceptional with careful calibration of the CMS. The dynamic backlight action after calibration in Movie mode was fast and unobtrusive. I got 58 ft-l of light output, which is good for a moderately bright room. Resolution was excellent at 1080i and 1080P. I did not test lower resolutions.
The subjective look was stunning! This set has tons of "pop", and it has beautiful color. It looks very crisp and detailed. Since it came out of black slowly, dark objects are just a bit too dark, but that's very forgiveable considering how great it looks overall.
I then calibrated the Panny 800u's THX mode, which made a huge improvement over the uncalibrated THX mode. After cal the 800u put out 40 ft-l on a 100% white window. We looked at the same scenes on both sets. I know we compared 58 ft-l to 40, but I didn't want to handicap the Sammy by reducing it's light output. After all, that's one of it's most important advantages; it wouldn't be fair to take that advantage away.
The Samsung had more apparent contrast ratio. It was easy to see the difference; it just won that contest hands down.
The Samsung appeared a bit sharper and had more vibrant colors. Flesh tones were neither too sunburnt nor too pale; they looked perfectly natural. However, it's high low end gamma meant that shadow detail was harder to see than on the Panny, which errs in the opposite direction (the 800u comes out of black too fast). The Panasonic has a natural, forgiving look that is easy on the eyes but not as involving. Overall I preferred the Samsung because of it's higher contrast ratio, higher light output which makes it more versatile and well suited for bright living rooms, and superb color. But I still like the 800u; it's natural, easy going look and lower price are important.
Attachment #3 is the measurements of the Samsung's calibrated movie mode.

I want the 7100 so bad. My A750 puts out so much heat, it's unbearable during the summer in my tiny apartment.

Back off man, I'm a scientist.

Are they still using white leds in Luxia??? Has anyone read the manufacturer for most HDTV leds tell all about direct blu(950) vs edge blu (luxia) It seems only improvement is ENERGY savings NOT pic quality... Check it out... Plus they say leds burn at different rates color wise so more chance of screen uniformity... (Sony xbr8) so please let me know thanks..

Hi,

Did you have any calibrated measurements from your tests? What would they be in say fL or cd/M2?

If it approaches 0.003fl, the B series will be at or around the 950. So keep than number in mind.

the A750 is pratically a cool cucumber compared to my pan plasma. I don't think you can get any cooler than lcd's right?

well hopefully they use white leds since rgb leds burn at different rates therefore longer life out of white leds compared too rgb since they burn uneven can cause screen ununiformity issues later...

I can't remember, but wasn't it confirmed that this set uses white led's?

I am contemplating buying this set, because I happen to get an insane employee discount at a certain big store, plus it looks awesome and a 32" just doesn't cut it for me being a college student and all.

I will the 32 to my bro for 600, so that will help too, just gotta figure out how to pay less than 400 for the service plan, lol.

My main reluctance stems from seeing a picture of the late 09 models which supposedly features ld-led's, and the 8100 coming out in the near future, which cosmetically looks even better imho. I'm sure it was just a picture fit into a blank screens picture, but the blacks compared to standard led's looked insane.

Beyond that, would it even be worth investing a good 1k or more into the 8100 just because it is 240hz instead of 120? Don't remember there being any other major differences besides those.

I finally got to the see the 7100 at the local BB and they also had the G10 and S1 near by so I could see them both at once. The 7100 looked great and super thin, was almost shocked it was actually that thin. The G10 looked more grainy than the Sammy, even my wife said the same thing. I asked about reflection or glare to one of the sales people, and he showed me if I look close and up toward the light you would see it but little fuzzy. IMO, I would take the 7100 over the g10 or the S1 (it was right next to the G10).

when mounting the stand to the TV be careful.
the holes don't align up that good when using the mounting screws.

I made a mistake and said one of the screws stripped. It just wasn't turned in enouph turns.
so no stipped screw!

Chris,

If maybe a little cheaper, I would. But the tv faces the dining room that has glass doors to the outside and in the evening I get the sun right on the screen of the TV I have now (Hitachi 60 Projection, came with the house we bought). A lot of light in my living room with the glass doors and 2 big windows in the living room to the right of the tv. So I need something that doesn't have any glare or matte screen, unless you guys have another idea.

Note: This is the only place in my living room that I can put the TV. If you want me to take a picture of what I am talking about, just ask.

Saw a 55B6000 in local fry's. Wow! Great black level and really thin. Was running on 'Natural' mode, backlight 10. The build quality of this TV also looked pretty good compared to the old ones (750, 860 etc.). Pretty sure 7100 will look better than 6000.

Your telling me...I go blind when its around 5pm here. Thats why hoping to find a matte screen to hopefully minimize the issue. This tv is bad I know, its 14yrs old and came with the house when we bought it 8 months ago. I have a big wall to fill, so a 52in or 55in would fit good on the big wall.

Just saw the 46" 7100 at the local BB. Gotta say it looked great. It was above an XBR6 and totally crushed it which is to be expected when only comparing to an XBR6. At one point the screen was only showing the circular door of a washer and the rest of the screen was black. It definitely looked blacker than pretty much all the other tv's on the wall.

Don't get me wrong I understand that the tv's in the big box stores aren't set up the way they should be but this puppy was pretty clearly a winner. They had just put it up and all the BB guy's were geeking out over how thin it was. In the span of 15 minutes the sales guys brought over at least 5 different customers to show it to them. It definitely wowed everyone who I saw them bring by to see it.

Funniest part was that two of the BB guys working the TV's said it was "OLED". I laughed and almost corrected them but they were so nice I just let it slide. The guy did say they just got a 55" 7100 in also and they might put it up tonight so I may head back tomorrow just to see that one too. For the first time seeing it in person I was very impressed with it.
