LN40B650 vs. LN40B630: I know that the LN40B650 has a contrast ratio of 100,000:1 and the LN40B630 has a contrast ratio of 80,000:1, but other than that are there any big differences between the two?

I got the b650 for 999 (in store only) at fry's, so it was much cheaper then the the b630 (don't go on sale as much). Actually I got it at 1199 and they dropped the price, so I got the discount a week later. I like the shiny screen, so yes, the color on the 650 is better if you have no reflection. If you have lots of windows then maybe the 630, but I don't think it is a big deal. The 630 looks amost like the cheaper sony v5100, so you might as well just get that. I spent a lot of time at the store looking at these. Your eyes will be your judgement and my eyes liked the 650 more. Spec different: 650 is 100,000 vs 630 80,000 dynamic contrast ratio.

The A630 has 40000 dynamic resolution and the A550 has 30000 dynamic resolution. The higher resolution supposedly gives it better PQ but I don't know how they compare watching them side by side. Other then the 120Hz I don't know what other differences they have. If you go to Samsung.com you can pull them both up and compare them.

There are a few differences between the various Sammy 40" LCDs. Some may not be so important to most: such as, styling; side mount speakers vs bottom; some have Game Mode, which Samsung says speeds up vdeo processing; but the most important diff between them (and probably the one that leads to the price diff) is contrast ratio. As an example the cheaper of them, the 4041 has 3000:1, and the 4096 has 6000:1. BIG DIFFERENCE. The others fall somewhere in between.

Owning both the 55-200VR and the 70-300VR and have compared not only both but two copies of the 55-200 on two Nikon DX cameras against the 70-300. Viewing was done on two hi-def monitors (25" and 27") using close to two thousand pics. Bottom line- the 70-300 blows away the 55-200. It is not even close. The MUCH heavier 70-300 is considerably sharper, colors are balanced and accurate (as they are on the 55-200) but much richer, brighter, with better contrast and much better bokeh. Skin tones and portraits in particular are wonderful with the 70-300. Downside on the 70-300 is that it is heavier. I have read some comments that the 70-300 begins losing sharpness after 200mm but my copy is super sharp at all focal lengths. If you are a serious amature and can justify the price go for the 70-300.

I just compared the Sony XBR4 with the Samsung 71F. I found that the Samsung had deeper blacks, but to the point of hiding details in shadows or low light areas of the picture. With the Sony, the blacks were not as deep but it was possible to distinguish more detail in low light images. Overall, I found the Sony's picture to be better.

I'm not sure since I didn't get to see a comparison between the two when I went to Best Buy, but I found out that the PN42B400 model has the same E-panel technology (wide enhancer 2, .001ms response, 600Hz subfield motion, mega dynamic contrast ratio) as PN42B450's, except for the Filterbright antiglare feature. For me, it didn't justify paying an extra $124 just for Filterbright and a few extra ports. Hope that helps!

I am certainly no TV guru but, I had purchased the LN40A550 & returned it & bought the LN40A650 & could not be happier! We noticed immediately that the picture looked faded on the 550 & went to one of the local retailers & found that this is a common complaint on these units. They actually had a LN40A550 & LN40A650 side by side in the store & there is a huge difference. We are very impressed with the picture quality regardless of what we are watching. We have had many friends commenting on the awesome picture on this TV. Hope this helps. Les

6003 and 6000 both dont come with wifi adapter. Other difference being lesser USB ports - 2 on 6003 and 3 on 6000 and no optical audio and ethernet ports on the 6003 variant. Contrast ratio is 4,000,000 on 6003 and 5,000,000 on 6000. un46d6050 is same as 6000 except that it comes with wifi adapter and has a contrast ratio of 4,500,000. Best part is it comes at same price as un46d6000 - currently 899$ from Sams!

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.

Great question. I can't find any customer reviews for the 630 model. I heard it described as "semi-matte." Which is why its contrast ratio dropped to 40,0000:1 from the 650's 50,000:1. I'll let you know more when I get it.

I'm also trying to decide between the two. Only difference seems to be that the 52b750 is 240hz instead of 120hz for the 55b650. I think that has something to do with response time. Hoping that we can get responses indicating whether or not the average person can notice the difference when watching tv. I would rather spend an extra $100 for a larger tv but wonder if I would be missing out on a better picture with the 240hz.

I have purchased both P65ZT60(brand new) and P65VT60(2000+ hrs display model) and applied calibration settings available on the internet to both of them(identical settings). End results were identical images on both tv. I custom tweaked it a little on contrast and brightness to give it inky black and extra kick. But you should be fine copying professional calibrations available on the internet.(or use the one I just posted on the Amazon).

series 6 has 10 bit panel. series 5 had an 8 bit panelOnly difference is 650 has a gloss screen - which is horribly reflective in the sunlight. Many reviewers suggest the 630 over the 650, because the contrast ratio (40,000:1 vs. 50,000:1) is really just splitting hairs.

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.

Thanks. Sadly Amazon gets finer details wrong some of the time. I posted this same question on the gold box page and was directed to www.sonystyle.com. The 504 TV is a 720p just like the L5000. It costs less everywhere you can find it listed. The contrast ratio is listed as 8,000:1 as compared to 13,000:1 for the L5000. Also, the MSRP for the 504 is $399... so I fail to see how it is a "doorbuster" at $379. The 32L5000's MSRP is $449. It was on sale less than a month ago for $399. Value wise $50 off is $50 off. I'm just going to wait for the 32L5000 to be $399 again.

The difference is the lens. You will have a gap of 20mm that you can't make up unless you buy the 55-250. That is why I bought this package. But keep in mind that even though the other one is cheaper, you eventually find that you will need the 55-250mm lens.
