Samsung UN46D6000 LED LCD HDTV HT Labs Measures

HT Labs Measures

Full-On/Full-Off contrast Ratio: 10,133:1

As mentioned earlier, the LEDs shut off completely when the TV is displaying a full black field, which doesn't often happen with real program material (except sometimes in inter-scene blackouts). So I measured the black level using a low-APL PLUGE pattern, which is mostly black. The black level I measured in this way was 0.003fL, which is excellent—better than most flat panels these days—but the mostly black pattern revealed non-uniform lighting across the screen, a nearly universal problem with LED-edgelit LCD TVs that is evident only in very dark scenes.

Turning down the backlight brought the peak-white level to 30.4fL, which is just about perfect, leading to an exceptional peak contrast ratio without resorting to any dynamic-contrast trickery.

At the Movie mode's default Color Tone setting of Warm2, the color tracking/grayscale was closer to correct that just about any TV I've ever reviewed. There was only a very slight rise in blue toward the upper end of the brightness scale. Using the 2-point calibration controls, I was able to correct that slight rise in blue at the top end, but the difference wasn't really visible.

With Color Space set to Auto, the color points are nearly perfect. Cyan and magenta are slightly off, but not that anyone would notice on real-world material.

Setting Color Space to Native, the color points are not as accurate as Auto, though again, the deviation is not pronounced. I used the Auto setting.

3:2 = film-originated content sent interlaced to display (broadcast movies and many TV shows)

2:2 = progressive video-originated content sent interlaced to display (not common)

MA = Motion Adaptive (interlaced video-originated content sent interlaced to display; becoming common for 1080i TV shows)

The Film Mode default is Auto2, which fails the 3:2 and 2:2 pulldown tests in standard definition. The Auto1 setting passes both tests. This is one of the very few displays I've seen that passes the 2:2 pulldown test under any circumstances. All in all, the video processor in this set is excellent.

I sure wish I had the same luck with my UN40D6000 that I have been goin through hell with. Im on set number 3 now and the only reason I keep going back to it is because it is a TV for my wife in our bedroom and she loves the style. I had 13 dead pixels on my first set with white blobs all over the screen with a black screen or any full screen color on the first one. On the second one I had 7 dead pixels with even worst uniform issues. So now I am on set number 3 and it has 4 dead pixels with the same uniformity issues. Netflix is unwatchable on my set due to drop outs and as you said when you stream movies in turns the settings to torch mode. On the UN40D6000 if you stream content with Netflix it will not allow you to adjust video settings. Stuck on torch mode I am very surprised the difference between the 46 and 40 in version. If you were to tinker with my set you would not have given it a Top Pick. Must be alot of variation between sizes. Between dead pixels, unwatchable Netflix, white blobs during all black scenes, discolored corners due to flashlighting, and I can not recommend the UN40D6000. All of my settings were the exact same as yours except the gamma was left at 0 and I did not adjust the hi and low RGB. Thankfully you had better luck with the 46 unless they sent you a ringer. Love the podcasts and keep up the great work Scott!! Im a huge fan!

How incredible that we've had such different experiences with the same model line! I can't imagine that there's any functional difference between different sizes of a given TV line, so I have no idea how this could happen. In fact, Samsung didn't have a review sample to send me, so they bought the TV at a retailer and had it shipped directly to me. I kid you not...Samsung had no chance to tweak the set before I got it directly from a retailer's stock.

I'm amazed that the set would not allow you to adjust the picture controls in streaming mode, since my set did. It did go back to torch mode for the Smart TV menu, but not for streamed content. Strange...

Thanks so much for the kind words! I'm grateful to have fans such as you!

Thanks for the reply Scott! Ya Im just as amazed as you at the difference in our sets. On the AVS forums many people are having either great luck or bad luck with the UND6000 line and I guess quality control is all over the place. After about the 100 hour mark or so is when the dead pixels start to show up. I got off the phone with a Samsung rep earlier and he indeed confirmed that some of the early sets functionality in streaming mode would not work so I guess all of mine have been early models. If it wasn't for these problems, including the little gnomes with flashlights in the each corner of the set as TJN likes to call it and the dead pixels and streaming issues, it would be an excellent set. Thanks again Scott!!!

Jarod, because of your comments, I've arranged to keep the D6000 for a while, and I'm going to run it up well past 100 hours to see if any pixels go dead. I'll keep you posted about the results, and if I do see dead pixels, I'll update the review accordingly. Thanks for bringing this up!

Cool thanks Scott! Looking forward to seeing if any show up. Thanks again. I have an update that I will post about my 4th (4th lol thats not a typo) 40UN40D6000 I just picked up and upon early run in it looks like a completely different set! Having great luck so far.

I thought I'd chime in on the issue about adjusting picture settings while watching streaming video--Netflix and the like. I had a Samsung UN55D6900 for a few weeks (so my remarks might not apply to the D6000, though what I'm about to say is true of the D6400s so...) and I initially thought that you could not adjust the picture while watching Netflix and other streaming video. The reason is that hitting the Menu button--which usually brings up the picture and other settings--wouldn't do anything during streaming. The trick, which I discovered by accident, is that you need to hit the "Tools" button, which brings up a number of options, one of which is picture settings. Was this your experience with the D6000, Scott? Is this of any help to you, Jarod?

Incidentally, at about $2000, and despite the great color and features, the flashlighting and uniformity issues with the D6900 were too bothersome to me, which is why I returned it.

Thanks Sunrise. I had actually tried that Tools does not work either.

I noticed the set seems to shudder, or skip frames when watching content on direcTV. The set is being fed a 1080i 60hz signal via the set top box.

Regardless of the settings I use, including the excellent settings provided in your review, it seems that every so often the picture stutters or runs at 2 frames per second. Even with Auto Motion Plus set to OFF I run into this problem.

Do you know what is happening here? I am currently using your settings. I don't have this problem with blu-ray discs or video game sources. I simply have this problem with DTV, so I assume it has to do with feeding a 1080i 60hz signal to the set.

Thanks, and great review!

Hi Scott,

What is the build date on this particular Samsung set you tested? Also what is the version number of it? Thanks
