Product Description

Product Description

Ready for a TV and a technology that will change the way you see TV and movies? Sony's 1080p KDL-52W4100 with Motionflow™ 120Hz technology creates a new standard for picture performance, with smooth, lifelike image quality that responds to the demands of even the fastest moving images with ease. Add to that unique features like the enhanced Xross Media Bar® with 3D graphics and integrated TV Guide program information, built-in DMex functionality, and other picture quality technologies like BRAVIA Engine 2™ and ACE contrast enhancement, and you can see why we call the W-series the new standard in 120Hz performance.

From the Manufacturer

Manufacturer's Description The BRAVIA W-Series is Sony's entry-point line of 120Hz HDTVs. Fastmoving sports and action scenes beg for smooth motion virtually free of visual artifacts and that’s just what BRAVIA W-Series HDTVs deliver with Sony’s exclusive Motionflow 120Hz technology. The W-Series doesn't have the 10-bit processor, x.v Color, or DLNA compliance of the Z- and XBR-Series HDTVs, beneath the sleek, piano gloss black exterior lies a host of Sony video enhancement functions delivering world-famous Sony picture quality to go along with excellent motion enhancement.

BRAVIA Engine works with Sony’s Advanced Contrast Enhancer circuit to dynamically deliver deep black levels that have the detail and highlights some other dynamic backlight systems mask. 24p True Cinema provides a direct connection to 24p video sources avoiding conversions while providing 24p cinematic picture quality. Sound enhancements such as Sony’s S-Force Front Surround technology paint the viewing area with sound and Voice Zoom lets you determine how much voice you want to hear versus the crowd noise. A generous set of inputs allows connection to a variety of video sources. And a well laid-out backlit remote control is included.

BRAVIA Engine Technology

The latest version of Sony’s respected BRAVIA Engine fully digital video processor uses a collection of unique SONY algorithms to significantly reduce noise and produce sharp, vibrant, life-like images.
  • Dynamic Noise Reduction: Intelligently identifies and dramatically reduces noise in the signal according to the motion and brightness of each scene for clearer, crisper images.
  • Detail Enhancement: Improved image enhancement algorithms render greater overall detail.
  • Contrast Enhancement: Works with the Advanced Contrast Enhancer circuit to optimize the contrast for every scene to create better depth and reality.
BRAVIA Engine technology optimizes the color, contrast, detail and clarity of every scene for the exceptional performance that BRAVIA HDTVs are known for.

Advanced Contrast Enhancer (ACE)

Part of the cinematic drama in film-making comes from details found in shadows and dark areas of the picture. Sony’s Advanced Contrast Enhancer (ACE)n uses real-time image processing to dynamically adjust backlight levels for improved contrast without masking details the filmmaker intended you to see. ACE delivers deep blacks in darker scenes, as well as fine details in shadows and other dark areas of the picture for a difference you can truly see.

Motionflow™ 120Hz Technology

No Motion Flow

With Motion Flow
Motionflow 120Hz technology doubles the number of existing frames by calculating in real time and inserting 60 entirely new frames between the original 60 frames. It uses a special Sony-developed algorithm that detects specific objects, as well as the movement of the overall scene and intelligently applies the right amount of enhancement. There’s
more to the story.

Unlike some other high frame rate technologies, Motionflow also includes Sony’s unique Image Blur Reduction algorithm, which reduces blur from the original source image captured by a camera before applying motion enhancement technology.

Judder is a visual artifact that shows up in video content that has been converted from film-based content. A visible jerking or stuttering effect can sometimes be seen during motion sequences on converted film-based content that may be noticeable on scenes that include panning.

There are many forms of high frame rate technology in the market today, but only Motionflow 120Hz technology uses special Sony algorithms designed to intelligently detect and apply the right amount of enhancement to reduce judder and deliver a smoother, sharper picture with more natural motion of the original film.

24p True Cinema

Movies and many prime time TV programs are shot at 24 frames per second. This means that TVs operating at any refresh rate that is not an even multiple of 24 will have to do some interpolation to present the content. TVs operating at at 30Hz or 60Hz traditionally solved this via a method called "2:3 pulldown". The television repeats the first film frame over the first two fields of video, and the second film frame over the next three fields of video (1, 1, 2, 2, 2), and continues to do this with the 3rd and 4th frames, the 5th and 6th framer (1,1,2,2,2 - 3,3,4,4,4 - 5,5,6,6,6), and so on until 24 frames are displayed over 60 refresh cycles. This discrepancy in the number of times frames are displayed can lead to a jerky motion in filmed material which some viewers notice  for example, especially with scenes that pan.

120, on the other hand, is an even multiple of 24. Ttelevisions with 24p capability, operating at 120Hz, can display an equal number of frames for every refresh cycle.

The benefit— You can watch movies in natural, cinematic motion, the way they are seen at the cinema. Every single frame of the movie can now be seen without using additional video processing that converts film-based images to video reproduction. Additionally, 24p True Cinema input capability can be used along with Motionflow™ 120Hz technology for outstanding fluid motion beyond what you would typically see at the cinema. Once you experience 24p video it will be hard to view video without it.

(Found in S, V, W, Z, and XBR Series HDTVs).

Sony's Blu-ray disc players wisely take advantage of this by including 24p output capability.

In 2007 Sony included HDMI CEC capability in select HDTV and BRAVIA Theatre Home Audio products, which led to a one-touch function Sony feature called BRAVIA Theatre Sync This feature allows the access and control multiple tasks and system operations with one button ease. BRAVIA Sync is now being introduced as the name for a new family of control features that not only includes BRAVIA Theatre Sync, but will now include BRAVIA Sync. This feature allows the user to control a CEC-enabled camcorder connected to a BRAVIA HDTV via an HDMI cable by using the HDTV’s remote control and an on-screen display that shows camcorder transport functions.

Optimized Theater Mode

Developed in consultation with the Sony Pictures Entertainment movie studio, most 2008 Sony BRAVIA LCD HDTVs feature our optimized Theater Mode. Selecting the THEATER mode on the BRAVIA HDTV remote automatically adjusts a number of key elements that have an important impact on reproducing movies better. Skin tones and lighting are seen as natural without over-enhancing color and contrast. The picture is fine-tuned for a dark viewing environment just like the cinema and optimized for LCD display technology. Even the right amount of film grain is included. All of this helps preserve the mood and detail so you enjoy the cinema
experience that you go to the theater to see, right in the comfort of your home.

Optimized Theater Mode is another great example of Sony HDNA in action. We not only create the exciting movies that you see at the cinema but also enhance the home viewing experience to
recreate it as only Sony can.

(Found on most Sony BRAVIA LCD HDTVs.)

Note: Optimized "Theater Mode" was developed in consultation Columbia Pictures, a Sony Pictures Entertainment company.

Audio Features

S-Force Front Surround
Built around a sophisticated set of Sony algorithms, the S-Force Front Surround enhancement function generates realistic surround sound from the two speakers in the TV. Unlike some other "virtual surround" technologies, S-Force Front Surround sound does not need to be bounced off of side walls or other surfaces to hear three-dimensional sound. No matter what the size or shape of the room it's possible to hear sounds from behind you.

SRS TruSurround XT
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 soundstage 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?

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.

I bought this TV in June 2008 and have found it to be an absolutely great buy. I bought my at RC Willey. Yes, I read the CNET review and the reviewer marked down the TV because of the dark shades changing. I looked at this in the store for several minutes and have lived with it for a month and have not noticed that problem at ALL! Personally I think they guy shot down the SONY because Samsung is running TV advertisements on CNET. This is a super sharp TV with excellent colors and deep deep blacks. This TV is much better than the old 2007 W. Here is why I bought this TV...It is super clear in digital broadcast and does a much better job in Analog/420p SD (old) transmitions than any other TV I have seen (no jaggies..thanks to Sony noise reduction/DSP). Sony knows Bluray- they invented it, they know what skin tones should look like like (they own a movie studio), thier menus are really easy/simple to use (vs. Samsung 650), it has a built in TV guide (You can get rid of that Monthly cable box fee) and it has future expansion capability.

On pure picture quality vs. Samsung 650:
* Picture: It is pretty darn close in digital broadcast. I looked at both side by side. Samsung has a slight edge on clarity in analog broadcast. Samsungs have more glare, Sony is a matte screen but blacks on samsung are pretty darn good because of the glossy screen. When viewing a BluRay DVD though, the Sony slightly more details. No fade from bright to black issues on sony as noted by CNET (he must have had a protype system). Colors are nice a bright and bravia 2 engine is even better than XBR4 or near it. I have heard the Z series may be better but they don't make it in 52'' yet.

* Menus: Samsungs menus are made for Engineers (lots of tweeks, but really confusing for average user).

I did a lot of research when I decided to buy a 52" TV. I'm a student and a part-time salesman at a fortune 100 company in consumer electronics. After weeks or perhaps months of preparation and research I narrowed down my options to the Samsung A750 and the Sony bravia w4100. Now I did have a Samsung A550 and a Sony Trinitron High Def CRT at home and they were both pretty impressive but I figured that Sony does a better job in 52" or larger category after observing the w4100 and a750 for several days at work.

First off lets talk about the screen. The 50'000:1 contrast of the Samsung vs. 30'000:1 contrast ratio of the Sony. The way Samsung measures its contrast ratio is radically different from Sony, that is why Samsung never discloses its "TRUE CONTRAST RATIO", but Sony does. In this case sony's true contrast is 3,000:1. Whatever the true contrast ratio of Samsung, it is not superior to that of Sony's. This is something that most experts agree on. It is easy to blast your dynamic contrast ratio but not your true contrast. Some claim that the Samsung produces deeper blacks but my answer is that this is due to Samsung's glossy mirrored screen and it has nothing to do with performance. The mate screen of sony absorbse white light coming from backlight or any ambient lighting from the room. This causes the blacks not to appear as deep or fake as the samsungs. Plus, Samsung manufactures all of Sony LCD screens so in terms of screen capability they are equal. If you have a bright room go for the sony, the screen is slightly brighter and not reflective like the Samy. The backlight for Sony seems to work brighter but its not as evenly distributed as the Samy, this is clear in the dark.

Second factor I checked for was the TV engine. We have the Samsung's Dnie Pro vs. Bravia 2.

***Updated*** (with new settings post firmware upgrade)

I have had this TV for 5 months now and could not be happier. This set produces excellent picture quality, amazing black levels and vibrant colors. The new Bravia Engine 2 also improves with 120Hz motion processing from Sony XBR4 line. My TV is located in a well lit room so the semi-matte display was a must. This TV delivers many useful settings to let you have the full freedom of making this TV truly yours. The PQ on 1080p material such as blu-ray movies or games is phenomenal. Broadcasted 1080i/720p HD sources look very good too - all depending on your provider and signal strength. SD quality is good but again it varies from channel to channel.

For everyday use, this TV will get some immediate props for its' picture delivery from any viewer. If you like sports, you can expect unrivaled video processing of fast action. If you enjoy movies, this Sony offers a combination of settings to complement the true 24p cinematic picture.

Since blu-ray movies are still expensive I have done a lot of testing by watching normal DVD's on my PS3 - and I have to tell you, those DVDs look better that HD broadcasts from Comcast. It feels almost unreal when you get to watch older movies with such clarity as if they were shot just a few years ago.

If you need some starter settings to get more accurate reproduction of colors and detail, feel free to use my settings (post update v.202):
