Sorry for the delay in answeringI was referring to the ambient light sensor. On the box and ads they refer to "auto adjust picture to room Light" which dims the picture when the room is dark. Sounds like a good feature but in a very dark room the screen was too dim for me. I went to Menue >picture >more >advanced picture >ambient LIGHT SENSOR and the selection is (OFF, LOW, MEDIUM, HIGH). Even at the low setting it was still too dark, so I set it to off.I down loaded the operators manual from the VIZIO site and it was a help. I made one call to the rep to solve one setup problem and I got some one immediately who solved it.The picture is great and I love the set.Art Sorry for the delay in answeringI was referring to the ambient light sensor.

I will defer to Calie and Joel on this as far as the numbers. I do notice if I stare at something that is supsposed to be black, I do see a slight bit of lighting (in other words, not the blackest of blacks) but real world, on HD, the picture is quite good. The toughest test for me is always seeing good facial features on fast moving, darker-skinned athletes, especially basketball players, where lighting is not always the best. This set accomplishes this well. National Geographic-type programs with large, outdoor vistas and amazing undersea colorful shots look fantastic. As long as the thickness doesn't bother you (about 4 inches), I don't think you can get more bang for the buck with this TV. I will defer to Calie and Joel on this as far as the numbers.

so is the difference only a usb port, same contrast ratio? panel, specs etc etc ?

I think you've said it. There is going to be very little noticeable difference in those two contrast ratios. However, I think the USB port is worth the extra few dollars. You get easy plug in to look at photos, play music, update firmware, etc.

Hi. Sorry. This seems not representation exactly a low-resolution.Thank you.

contrast 67bright 40sharp 0color 45color tone warm 1just eyeballed it to these settings, I heard THX DVDs like Cars have a feature that helps calibrate the picture settings, haven't tried it yet though.

I go into Menu, Picture, Picture Settings, then you have to adjust the color and tint to get it right where you want it. I have my Contrast and Backlight at 100, Dynalight is on, Brightness at 50, Color at 70, Tint at 0, and sharpness at 14. Hope that helps

It's important to note that there are two elements to the contrast ratio. There's the contrast provided by the 3 LCD screens, and then there is they "dynamic contrast" added by the auto iris that adjusts overall picture brightness. The 5030 is an advanced iris that boosts apparent contrast -- and I have to say it works pretty darn well. Even dark scenes have solid blacks and contrast.That said, it's almost impossible to set up a direct comparison (same lighting conditions, same materials). I'm very pleased with the 5030UB, but it's whatever you like/want to pay.

Sorry, can't help with this question as I was a personal buyer for this product to help the contrast with my vision.

Carefully read the specs! Some units will specify new electronic processing to almost virtually eliminate the blur you are concerned about; I noticed it right away in the perceptual clarity...you pay a little more but the difference is worth it.

According to Samsung, it's 1000:1. According to the July 9, 2014 review in Digital Trends, the "pre-calibration" contrast ratio reached 610:1.

As Brian M. states, contrast ratio is extremely important for picture quality. But the difference between the two sets that I listed above is in the _dynamic_ contrast ratio. Most people turn off the features that pump up the dynamic contrast ratio in order to get a better picture. What you want to compare is the _native_ contrast ratio for both sets, and I don't know what those values are. You may want to try avsforum.com or a similar site; I doubt native contrast ratio is available on Samsung's website.

The LN46A550 has a 30,000:1 contrast ratio while the LN46A540 has a 35,000:1 contrast ratio. That is the only difference I noticed.

I believe the one I purchased had a higher dynamic contrast ratio than the w2072a.

Visually you won't see anything, it only has the small light for the 3 different modes. But you should be able to hear the difference....especially when in Dolby Digital.

contrast ratio differ from dynamic ratios. you need to be careful when purchasing an lcd... it can be tricky. the higher the ratios the better. for example, on a Sony tv i saw (the one with glass trim around it) the dynamic ratio was 18000:1, while the contrast ratio was 2200:1. this is not so good. by what i've seen contrast ratios only go up to 15000-25000. also, 4-5 ms is the lowest made so far. most lcd's are 8ms. so if this is correct this tv isn't as bad after all. i would buy it!

I don't think that there is a difference in resolution, but the contrast is probably much better. But this is knowledge which I retrieved from internet. I am content with my 3d viewer V3.
