I just bought a the Samsung LED 8000 series 55″. How do I get the picture to stop looking like it was shot from a home movie camera? It’s like I am watching it from the 1st person point of view, not like a regular movie or tv show.
Please help!

Otherwise, the picture quality is awesome! Love the tv!

Great Post! I work with Sharp and know first hand about the confusion out there regarding LED TVs . These TVs are LCD TVs that are only backlit by LED lights which are far more efficient and brighter and more consistently bright all the way to the edge of the screen. The picture quality is far superior to standard LCD TVs and as an added bonus, the LED lights provide an execellant reduction in energy consumption.

I am not convinced these TVs are better than the older, LN52A/B750 and LN52A/B650 models. They certainly are much thinner and cooler looking and cheaper to run!

Those earlier models may have better contrast off-center, and they may have better brightness uniformity (less clouding). This is a new technology (the LED wave guide) for samsung and it hasn’t been the perfected yet.

The 1.2 inch thickness is definitely MUCH better than my LN52A850, which has the HDMI connectors shooting straight out the back (not sideways), which was stupid, imho !!

I purchased the Samsung 7100 from best buy just before Christmas. The picture quality was truly amazing as far as color & black depths. I did experience the “3D” effect some people have said they love while others claim to hate, for me some times I liked it others I didn’t. This was not a problem for me as it could be adjusted away. The deal breaker for me was that blurring could NOT be adjusted away. I am a commercial printer & my job demands I have an eye for detail. I returned the 7100 series & brought home the 8000 (both models 55inch). The issue still is there but much less notable. I can now live with what little blur there is. On the 7100 I couldn’t even play a game on my xbox 360 without getting a headache. I am nearly 40 years old & a serious gamer. If you are having issues gamming on the 7100 or 8000, make sure you adjust (turn up) ALL of your display settings on 360 & of course noting less than 700 monster cable(1000 monster cable preferred). Hope this helps my fellow gamers as well as anyone else with a sensitive eye to blur. Here is a good video I found describing the major differences between the 6000-7000-8000 led series.

I purchased the Samsung 55′ UNB8000 2 weeks ago at BB and have had a problem with it going black/quiet for 5 seconds. I’ve run the power through a Monster 1600 power filter and also straight from the wall receptacle. Voltage fluctuates between 118V – 122V. ANY THOUGHTS??? Will this hurt the TV? Return it?

Cheers!

Once again a report that measured vertical resolution increases with the LCD update rate, yet no explanation of HOW this can occur.

1) Since it is the deinterlacer that outputs lines to the LCD panel — HOW could the panel update-rate alter the functioning of the deintelacer? The deintelacer inputs a new field every 1/60th second. So even with the cheapest deinterlacer, at 60Hz, 512-lines from the input signal should be sent to any LCD. So how can an LCD TV display only 330-lines?

———–

In past reviews, cheap LCDs provided 330-lines, but the “Region LED” Samsung you reviewed last year provided about 630-lines at 60Hz and about 1000-lines at 120Hz. So why does this new Samsung need to run twice as fast to get the same vertical resolution?

————

2) Assuming the deinterlacerin the Samsungs is good one — on the level used in Plasma HDTVs — it should be able to output about 1000-lines under motion. These 1000-lines should be sent to the 1080-row panel! So, why wouldn’t EVERY update show ALL 1000-lines?

3) You report that at 120Hz, 640-lines are displayed? And, at 240Hz, finally all 1000-lines are displayed. What is it about the LCD panels that forces either 2 or 4 updates to show all the lines coming from the deinterlacer?

4) Alternately, perhaps it is the motion estimation circuit(s) that affect the number of displayed lines. Is the motion estimation (interpolation) chip somehow “creating” double the vertical resolution coming from the deinterlacer? If so HOW does the chip accomplish this task?

5) Bottom-line, as I read your review the viewer ONLY shows full vertical resolution at 240Hz. But, I think most of us agree that:

a) Interpolation should not be used with film sources.

b) But, if you turn JR OFF, in order to obtain full vertical resolution you need to run the set at 240Hz. But, showing film content at more than 48Hz (or 72Hz) creates a “video” look. So shouldn’t reviews make it REALLY clear that if you want to watch film without interpolation and at the minimum possible frame-rate (60Hz) — vertical resolution is going to be only 330-lines! Do those who use BD and buy these LCD sets really understand this limitation?

6) It seems the best one can get from ANY LCD is to buy one where you can turn-off JR (interpolation with 2:3 pulldown sources) AND can obtain full motion vertical resolution at only 120Hz. It’s possible that 120Hz is not so much greater than 72Hz — that film will still look like film. (However, having experience with 25fps film viewed on PAL 100Hz HDTVs, makes me strongly doubt anything above 72Hz will really be acceptable.)

7) Its been widely reported that the motion interpolation chips create unwanted artifacts. But, what about there ability to pass natural film grain? I suspect that these chips must filter-out random-motion detail (grain) in order to generate objects that are following more predictable motion paths.

Even if you only want interpolation for video (60i) such as sports — if you want to minimize interpolation artifacts you’ll need to lower the update-rate which, of course, also lowers vertical resolution. So, one could have spent tons of money to get the same 330-lines vertical resolution you get from a cheap LCD.

Picked up the Samsung 55′ UNB8000 on boxing day.. took down my 43″ pioneer plasma.. picture is beautiful very sharp colorful and vibrant.. but the panel upset me when areas of the screen go dark I can see white cloudy images mostly on the left half of the tv… very upset feel like returning it..

Been reading these responses and it strikes me funny.
One new plasmas consume forty percent less and are so close in energy consumption why any of you knuckleheads are buying inferior plastic well marketed same lcd technology for hundrends if not thousands more.Buy a 55 inch lcd instead of a 63 plasma that has a way better picture. You guys buy into some tech talk about 1080i vs 1080p when in fact a tv 50 inches or less you can’t tell. True with larger TVs Another thing how thin your tv is common on guys! Plasmas have a slimline at 2 inches and its a plasma. I bought a Samsung PN63B590 at 2300 dollars not led lcd that can touch it for picture cost and quality.Dont get sucked into paying antiquated technology because its thinner.Someone prove this wrong. Forget Best buy they have contracts with Sony and others and they are going to market what will make them the most profits they are double dipping the same mark up the second time around with Led terms versus LCD there using plastic to cut cost and material. Quality hmmm Mercedes and Bentley other higher end cars may not goes as fast as a Corvette but what a piece of fiberglass and plastic the vet has.

I just bought 8000 series one week ago. At the same time I bought flip mino hd camcorder. Initially I thought it may not be good quality of the video with 720i which is the out put of flip mino.But surprisingly picture quality is fantastic.
