Vivid Picture Quality

Full HD 1080p

Enjoy crystal-clear detail with Full HD 1080p picture quality. It's the highest in-home resolution available and takes advantage of the all-out HD experience of broadcast TV, satellite and other HD sources like your Blu-ray Disc player or PlayStation 3 entertainment system.


Motionflow XR 240 Technology

Motionflow XR 240 technology takes motion clarity beyond refresh rates, which are only measured in Hz, to double the motion effect for lifelike clarity. Golf balls roll clearly, with less blurring, as the camera follows them across the green. Footballs retain their detail and move smoothly as the camera pans quickly during a kickoff. Even quick motion seen in action movies appears amazingly realistic.

Clear Resolution Enhancer

Fine details and textures appear in whatever you’re watching, even in flat areas. Powered by Sony’s advanced noise reduction algorithm, this technology boosts image clarity with heightened contrast and depth that you won’t find on most televisions.

Edge LED

Edge LED

Experience Sony's Edge LED Backlight technology with the KDL46EX640. Powerful yet thin LEDs deliver a drastically brighter picture than conventional LCD backlighting. They also help achieve an ultra-slim TV design that looks beautiful in your home. Plus, Sony's Edge LED Backlight technology delivers outstanding contrast, rich colors and enhanced dark-scene detail.

Digital Noise Reduction

Enjoy ultra-vivid HD clarity and less grain while watching TV with the whole family. Digital Noise Reduction enhances detail in whatever you're watching with meticulous processing. It even helps clean up video from USB and other PC sources so the picture looks pristine and vivid.

Size: 46-Inch
I have had this TV for a few months now and am very pleased with it. Let my preface this by saying that I used to sell TVs for a living and I am pretty particular about picture quality. (I am particular about sound quality as well, and don't believe that any of the speakers that are built into TVs nowadays are worth a darn. I have all the TVs in my house hooked into separate audio systems, so you won't see me addressing the sound quality of this unit.) Many TVs out of the box have exaggerated colors and contrast, so that they will "pop" in the bright conditions of the store showroom. When you start up this TV for the first time, the on-screen display asks if this is being setup for store display or home use. When you select the home use option, the picture that one gets out-of-the-box is really quite impressive. I fooled around with the settings a little bit, but didn't find that I had to do much in order to have a picture that I am very pleased with.

The USB network adapter is easy to setup and configure. The internet apps are OK, but nothing that is going to take the place of my iPhone. On the other hand, I have streamed several movies from Amazon (both paid video-on-demand, and free movies from my Amazon Prime account) and have found the video quality to be very close to that of Blu-ray.

When viewing a black (or very dark scene) one can notice a slight bit of light leakage along the corners (particularly the bottom corners) of the screen. This is something that is inherent to varying degrees with all LED edge-lit televisions, but it is not often visible with this TV and unless one is looking for it, I doubt that many people would find it to be distracting.

We purchased this TV to fit into an entertainment armoire that we bought many years ago. The case size makes it a perfect fit, and with its swiveling stand, I can position it optimally.

The most important thing to me in a TV is the picture - and that's where this model excels. It has amazing contrast for an LCD TV, although much of this is due to the better capabilities of the LED backlight. it's impressive compared to many other flat screen TVs I've seen, including the 37" Sharp Aquos it replaces - with much better range of viewing angles and far greater detail. The Bravia also does an amazing job with standard definition TV, which is another area where the Sharp fell flat. Although it looks a little fuzzy here and there, you just don't see the same kind of pixelation I noticed in other HDTVs. Finally, this TV comes out of the box with little need for fine tuning. It will ask you whether it's being setup in a home or retail environment and configure the picture accordingly. I spent hours setting up the Sharp with different calibration tools - I didn't find this to be necessary with the Bravia.

This TV comes equipped with a plethora of connectivity options, which is important to me since we have a variety of devices connected (Blu-Ray, VCR, Wii, WDTV Live, etc) and with its swiveling stand, it's easy to reach the ports. Although I would have preferred the basic controls on the top of the unit, like the Sharp, they are not terribly difficult to access along the back of the right side of the set.

The picture alone makes this TV worth the money. But I'm deducting two stars for the other half of the AV experience - the sound.

I did a lot of research leading up to this decision. I was originally leaning towards the "top" brands that consumer reports and cnet were recommending. Those brands are Samsung, Panasonic, and LG. To be fair, this Sony rated well with consumer reports, but you can't just go by reviews, one has to go see the t.v. on display at a store, and that's what I did. After 3 visits to a big electronics store and observing the various models for a long period of time, I was leaning towards the 40 inch Samsung. Right next to the Samsung I noticed a t.v. that had a great picture and much more natural and richer color. In fact, the colors were much better! It was this Sony. When the Samsung demo was showing human skin tones, they were just not right. One darker toned woman looked orange but on the Sony, her tones were just right! After watching for a while I noticed that all the colors represented by the Sony were much richer and more natural. I was pleasantly surprised. I also noticed that I never observed any motion blur on fast motion scenes like a football game. I also noticed that Sony's use of LED lighting was better than Samsung. The Samsung model made people look too pasty. I went home and looked at CR's take on this model and it was rated very well. They said it had an excellent hd picture. Out of the two brands, the sales associates said they would choose the Sony. I made my choice and bought this model. We absolutely love it! So glad I took my time and went and watched them in the store. Just got hd service and we are so happy with our decision! Let me remind you that Sony has been making t.v.'s for a long time and I am glad I chose them. Also, it's great to have Netflix stream right to the t.v. Hope this helps.
