Wide Color Enhancer/Cold Cathode Fluorescent Lamp

The NTSC (National Television Systems Committee) has established the color standards all TVs in America try to meet. And typical LCD TVs only meet about 72% of this standard. Samsung LCD HDTVs use Cold Cathode Fluorescent Lamp back lights to give you 92% coverage of the NTSC standard, ensuring truer, more breathlessly vivid colors.

Samsung’s exclusive Wide Color Enhancer technology delivers more brilliant colors, even in bright areas of the picture where blues and greens are washed out on conventional screens. The system displays wider color reproduction, showing you truer colors – the fresh green of spring foliage, the intense blue of the summer sky.

A wide variety of multimedia devices can be connected to the set through any one of the four Simplay compliant HDMI 1.3 inputs (including one on the side), and the handy HDMI-CEC feature lets you control all your CEC-enabled peripherals using just one remote.

Connect HD digital devices like disc players, game consoles, and satellite dish components into the 2 rear connections and use the side-mounted input for cameras, camcorders, and laptops. HDMI is the best performing interface for displaying an HD source on an HDTV.

Audio Features

TruSurround is a patented SRS technology that solves the problem of playing 5.1 multichannel content over two speakers. TruSurround delivers a compelling, virtual surround sound experience through any two-speaker playback system, including internal television speakers and headphones. It is fully compatible with all multichannel formats up to 5.1 channels. High-quality virtual surround sound can be experienced with just the two hidden, downward-firing side-mounted 2.2-channel dome speakers built into the TV.

SRS TruSurround XT technology delivers an amazing, simulated 3D effect with clear dialog and powerful bass.

TruSurround XT audio also adds three audio enhancement technologies to produce an amazingly immersive sound experience.
  • Dialog Clarity brings movie dialog into Focus during the playback of any surround-encoded material to make speech much clearer and crisper.
  • TruBass creates incredible deep rich bass allowing a person to perceive significantly deeper, richer low bass tones that are far beyond the physical low frequency capabilities of the speaker itself.
  • The SRS WOW feature widens the sound stage by processing standard two-channel stereo material as well as multi-channel encoded material for a dramatic improvement in the playback of any stereo audio over a two-speaker system.
Stereo broadcast reception is offered for MTS and SAP with 181-channel capacity. A sound leveler keeps audio volume consistent during channel changing.

Which Size HDTV is Right for My Room?

HDTV Size chart
With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience.
If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.
  • Minimum size = Viewing distance/3
  • Maximum size=Viewing distance/1.5

By Joseph Esposito on April 26, 2008
Since pretty much everyone on here has given this TV the same praise, I will spare you all of the details it is certainly the best TV for the money out there today.

However, my customer service experience is something to note here. Like others, I was wary of making such a large purchase online. Low price + no sales tax and free shipping made up my mind. After seamlessly receiving the TV 4 days after ordering it, it broke withing 3 hours of being delivered (there was a loud snap-like sound), and there was no power. I immediately contacted Amazon, who told me to contact Samsung directly, and if they could not handle my concerns, call back. Samsung dispatched a technician to my house 4 days later, who told me that he "thought" it was a defective power card, and that it would take 1 - 2 weeks to get the part and come back for repair.
Now I think most of you will agree that you wouldn't want a TV that was refurbished after just 1 day. Samsung refused to replace it, saying their policy is to repair, not replace. I then emailed Amazon, asking for a new television, giving the above explanation. When I called for an update the next day, my issue had already been escalated, and a new TV was about to ship, no questions asked, at 0 cost to me.

In the end, I have Amazon did everything I asked and more, including crediting my price 4 times, from 1700 all the way to 1469. The biggest fear in buying something like this online is, "what if it breaks???" Well, mine did break, and if you buy from Amazon, you can be sure that you will be happy in the end no matter what.

First things first, I ordered this TV directly from Amazon and within a few days the price dropped and Amazon refunded the difference. Awesome! Amazon's White Glove delivery service delivered as promised and was OK to deal with; no issues at all. So for those of you wondering whether it is better to spend a few hundred bucks to order this set from a brick and mortar store; keep your money in your pocket and order from Amazon.

As for the TV, I am not a video expert type, but I do research big ticket items thoroughly before buying. This set and the previous generations received great reviews. However, I was torn between plasma and LCD. Being a big sports fan (lots of fast moving action on the screen) I had been leaning towards plasma. But the reviews of this set and the benefits of LCD over plasma (lighter, uses less energy, no risk of burn in and better for well lit rooms) made me make the plunge.

Overall, I am extremely satisfied. This is my first HDTV and I am using Directv HD service and the picture is outstanding. It is sharp, bright and overall beautiful. The only issue I have, which I was worried about with the LCDs, is that I do notice some pixelation when scenes move very fast (Thus 4 instead of 5 stars). However, it is not distracting but I do notice it.

The speakers are not as bad as some of the reviews would indicate. You just need to set the equalizer to the right settings. I have a home theatre set up so this is not a big issue, but to some it is so I thought I would comment on them.

The set looks great, is easy to set up and I am very, very, very happy with my purchase. Especially at this price. With my extra money I was able to buy a nice stand for the Samsung.

I hope this helps.

Verified Purchase
Why I bought this set:
My old tube TV suddenly burnt out, I guess it sensed that the change was in the air... I originally wanted to go with a 42" 720p set, but my partner insisted on getting a 1080p TV so "We'd be ready for the (near) future." After reading many reviews, I learned that you won't appreciate the 1080p hi-def on a set that's less than 42". So I started to look for a 46" 1080p TV, and my budget was [$...]. I first looked at 4661/4665 models, but soon realized that they were being replaced by the 46A550. Even though this is a 5 series TV that replaced two 6 series TVs (well, sort of, consider the 4/5/6/7 classification is new for 2008), the 46A550 trumps its predecessors in specs, mainly the contrast ratio. You might have read that the contrast ratio varies from one manufacturer to another since there's no standard for measuring, so it didn't matter too much for me. I also read that 4661/4665 had some firmware issues, and at the time of purchase, they were actually more expensive than 46A550 on Amazon. So 46A550 became the clear winner.

So far so good. It's important to note that I currently do not have any HD input-just the standard cable signal and Wii via composite cables. Of course the picture quality is OK at best, but I am hardly complaining as I have faith in the set. Because this set is new (mine was assembled on March 31st and arrived to my house 10 days later), there aren't many extensive reviews online yet. Usually, the Sony sets lead the pack in comparison reviews, but they usually cost [$...] more than the runner-up. To my eyes, the Sony tends to display more details and Samsung does a better job delivering vibrant color and contrast.
