Question: ln46b650 vs ln46a850 vs ln46b750 I am planning to buy an LCD. I finalized LN46A850. But then two new LCD's were released LNB650 followed by LNB750. Based on the feture set, price and looks i am still thinking of LN46A850. But suggestions and advice are requested.
Document: I was thinking for a long time of getting the 650 52" LCD from Samsung because of the size, and because it was the best value a la Consumer Reports. While most of the research was done on-line, I also went to Best Buy and SAM's club etc. to see how all the sets they recommended compare.It was at a Best Buy when I decided that the 650 52" was still the one I wanted, when I happen to pass by this set on my way out.
I own several HDTVs both plasma and LCD and various manufacturers. Hands down the best picture quality. It blows my mind. Even HD over the air looks superb, it has an excellent built in tuner and the menu if very simple.Buy two, I'm serious!
Another common issue re the set blocking other remotes was not present with my Time Warner box and with only a little effort the Samsung controller was able to take over the basic features of the cable controller. Although the speakers are in a seemingly strange location and pointing downward, I found the sound to be more than adequate, especially if you select the simulated surround sound option.The new generation of LCD LED sets may offer some picture intensity improvement but this set more than fills the bill and at a significantly lower price.
After information overload from all of the various manufactures as to why they were better we settled on the Samsung brand just to start narrowing it down. After that we took up the Plasma vs. LCD. We settled on the LCD and then quickly narrowed it down to the 46" model based upon our living room layout. We have three interior and one exterior wall, with the exterior wall facing east and is all glass.
I purchased the LN46A850 after a lot of research. The picture and sound quality are superb for both HD and SD programs and the multiple HDMI and component inputs made it easy to hook up HD cable, DVD-R and computer and still have room to add Blu-Ray in the future. The super-thin profile looks great, although I've not yet wall mounted it. All in all, completely happy with the purchase.
Purchased in march of 2009. Now in April of 2011 I have two black verical thin bars which appear about 3 inches in from each edge when I turn the tv on in the morning. They fade out after about 30 minutes, but should not be there. From what I read on the forums it is likely the panel which they indicate costs almost as much as a new tv. Sorry, but when this becomes unusable it won't be another samsung that I buy.
We've also been taking advantage of the NetFlix "instant" movie download capability. Although not nearly as sharp as a Blu-ray movie, it's still very clear and a really cool feature.Purchasing these components through Amazon (vs. Best Buy/Circuit City) saved me several hundred bucks, which I in-turn used to buy the better Blu-ray player. I was also pleased with the home delivery service for the TV.
We are enjoying our new 46 inch Samsung. The image is great, the sound is good and the feature set is very good. The TV is far better than the instruction booklet, which reminds me of a Japanese computer manual. The manual needs work. We debated this vs. Sony and are happy with the Samsung.
This was my first LCD purchase after researching reviews from various online reporting sites. I am not dissapointed at all. TV showed up in great shape from the CEVA shippers. Hookup is greatly simplified with the HDMI connectors. A stunningly beautiful picture right out of the box. I like sports and do not notice the stutter movement Ive heard about with the 60Hz refresh rate LCD's. SPorts are an entirely new TV world to me now. The things you notice in HD are amazing.
I was looking for a good quality flat screen and had been thinking of buying the 50" Pioneer Kuro. It wouldn't fit in our entertainment center so I went shopping and was recommennded by several friends to check out the Samsung LN46850. I found that the LCD picture was sharp & bright, good features for our well-lit room. The price was about 1/3 of the price of the Kuro.
Answer: There's a promotion going for the LN46B750. Amazon is currently selling it for $1,999.99. Input coupon code, "SAMTV300" and it drops to $1,699.99. I'm pissed because yesterday I picked up an LN46A860 from Crutchfield for $1,579.99 with 1% FW cashback. It already shipped, bleh.Specs wise, seems like everything is the same except that the LN46B750 introduces 240Hz motion and Internet@TV (Yahoo!, YouTube, Flickr, etc.). Also, the LN46B750 has a charcoal ToC while the LN46A860 has a dark blue one. Moreover, I haven't come across a review that details the performance of the 240Hz motion.
