the b640 has most of the specs of the b630, but with the glossy finish of the b650. I am a fan of the 120hz and you notices the different with your blu-ray player or PS3 and the dead HD-DVD. It makes things pop-out a little and look a little unatural, but is like 3D on some movies. When you turn it way too high you get the halo effect and some blocking on fast scenes. Most people will buy a blu-ray player sooner or later so I say just go with the 120hz for the future. If you turn it off it is just like watching the b550. Most antenna broadcast will not pop out as much, since the source is not as good.

I've had my 52" 650 since memorial dday weekend...and coming from the video industry, it's the best screen around. For thos of you comparing the 650 vs 750 vs 850; check the technical details even at a store. I walked into the CC & BB locally and yes they were all set up side by side; but since the local store wanted to sell more 850s, it was "tuned" better. The default settings have changed including the brightness level; so when you are comparing TV screens; make sure that the identical output; down to the connection is being used and that both units are identically tuned, i.e. brightness, contrast, presets...99% of the time you will find them not to be. The best tuned TV this week will not be the one next week!

I just purchased a 550 from Circuit City last week. They are one of the few stores that puts a 550 650 750 side by side. The audio on all 3 was the same, average at best. This is what I found with almost all LCD HDTV with small speakers. I bought the 550 because my eyes could see very little difference if any between the 3. Most difference was the options. The Samsung did have the best picture.

I bought a LN52B750 after a great deal of research. Unfortunately, I cannot take anymore of the fake looking/soap opera/camcorder type picture with this tv, especially after adjusting to minimize blurring. Due to headache and visual strain, I even stopped watching this tv and I am sending it back for a plasma. Hope that helps.

I just purchased a Samsung UN40H5203 - a 60hz refresh. I am enjoying the rich color, but I find that for sports - football and basketball so far - the 60hz can't refresh fast enough to eliminate what seems to be a pixelation where movement is fastest. Otherwise, not issue. Perhaps if I were looking for a TV with a screen as big as the Berlin Wall I'd want the 120hz, but when I bought I saw a $200 difference between otherwise similar Samsung sets. Not worth the difference.

120Hz is a different picture, some like it, some don't. You can always turn it off though. Contrast, however, EVERYONE likes better contrast. Go with the 55" Samsung. I own a 5271F Samsung and I love it. I am waiting for Samsung to pump out a 60 incher before I upgrade.

It is 60hz. I can certainly understand your confusion. Please, read the rest of the responses for more info. SonyStyle was very disappointly and cleverly not very clear about this feature in this tv, which is unfortunate for a company of its stature.

I don't know how much help I can be but I'll give it a shot. I bought the Samsung because I own a Samsung LCD 46" bought in '08. I was quite happy with that TV so I stuck with the Samsung brand. I really think the 46" has a better picture than the 65" LED. Could be because of a consequential loss of picture clarity that comes with larger screen sizes. The UN65 has a dual core processor but if you're really into "smart," I recommend the quad core (more money of course). I subscribe to NFL game replays and they won't load well (and therefore can't view) with the dual core; I have to use my quad core computer. I think the UN has a really reasonable price, but you generally get what you pay for (as the old saying goes). Bottom line . . . I like the UN65 but, at the same time, I am a little disappointed. The only way you'll ever know is to look at them side-by-side and remember, showrooms do not have real-life broadcasts (in most instances) so when you get one home, your picture may not be a great as in the showroom. Hope this helps somewhat and good luck!

Its a very good question. Looks like this TV is 480Hz compared to 553 (240Hz) and probably has functioning USB ports (according to specs at least). Other than that I see no real difference for 2D pics.And there is the chance by implementing 3D, some 2D quality is compromised. (Of course it may have corrected some of 55s's issues also)I guess we have to wait to see whether 554 is better in 2D than 533. However if you are not interested in 3D, I don't see it being worth $500 extra .. However I think the prices for the 554 will be coming down further in the coming weeks/holiday season.

I have the 60LA7400 with 240Hz and I have a 55" Samsung with 120Hz and I really cannot tell the difference. All Bluray players send a 60Hz signal and the TV's procesor uses the 240Hz to show you the best quality picture. Also do not be fooled by people that tell you that you need a 3D ready or 120 or 240Hz ready HDMI cable. All HDMI cables are the same except the ones that have Ethernet capabilites and there is not technology for that yet. A $10 HDMI cable from Amazon will show the same quality picture as the $200 one a salesman will want you to buy from yor local electronics store. The only diffence is the amount of shielding in the cable that the $200 has, so unless the cable is going from your Bluray around your washing machine then around your dishwasher to your TV your fine...HDMI is digital, either it works or it doesn't work.

If TV-based sound is important to you then the LN52A750 is the right model to purchase. That model has subwoofers in the 2-speaker system and it has the best sound of the 6,7,8-series samsung models. In my opinion, you are getting your money's worth (DLNA and USB interfaces, better sound) for the extra $100 over the 650 model. Also, check out the $150 blue-ray discount feature, you can get a blue-ray player with the TV for net-net, $50 extra !!

The product specifications show a difference in contrast ratio and response time. LN55B650: 1,000,000 to 1 contrast ratio - 4ms response time LN55B650T1F: 5,000,000 to 1 contrast ratio - 2ms response time However, there are discrepancies in both of the product specifications showing 100,000 as contrast ratio instead of 1,000,000 and 4ms shown for both sets, making those specs worthless, or at the least, unreliable. Check the Samsung site for better specs.

Not to hijack your thread but I'm kind of in the same situation. I want to get a TV for Bluray but am not sure to wait or buy now.Also, is the extra 150$ worth it from the 61 to 65 model? The only difference I can see is the 5,000 point difference in Contrast Ratio, is that worth the extra money?Thanks.

I purchased a samusung 40 led tv. It is a 120 hz according to the box it came in. Also according to samsung customer service reps. But yet on the back of the tv where there is the UL label it says the tv is 60 hz. Noone at samsung seems to know why. I spoke to many of their reps and duh they have no idea why. Does anyone know why there is this difference?

I picked up the Samsung set for $1355 free shipping and no tax, so I saved more than $175 by purchasing the Samsung over the LG. Also, when I looked at the LG model, I thought it ran on 60 mhz refresh. The Samsung is at 120 mhz. When I compared the pictures in the store, the Samsung looked "glossier" to me, and I like that appearance. The LG was more of a "matte" finish, for lack of a better description. The picture of the Samsung is much more superior. I viewed it in a showroom with a special dark viewing room, and the difference in the dark room was VERY noticeable. Moreso than in a bright showroom. You will like the viewing angle of the Samsung much better. It is worth it. Check out the prices online. Mine even came with a free wall mount. Nice.

Honestly, I'd like to add the 550 to this mix.Amazon has a page that list what each series adds, but it is very far from clear:Samsung LN52A650 52-Inch 1080p 120 Hz LCD HDTV with Red Touch of Color (2008 Model)Anyone find a better link that clearly states what the 650 and 750 add?
