Full HD 1080p

Full HD 1080p logoFull HD 1080p means our connections accept 1080p signals and the display will render that signal in Full HD 1080p. The flexibility of native 1920 x 1080 displays allows any high definition content to be viewed without the need to downconvert images to the native resolution of the display. Take full advantage of Blu-ray Disc players and PlayStation 3 systems that can deliver 1080p content.

Digital Media Extender (DMex)

Sony's Digital Media Extender (DMex) offers a digital connection path for optional modules like the BRAVIA Internet Video Link, as well as other modules you can add in the future. Innovative DMex expansion capabilities integrate into the award-winning XMB user interface making HDTVs a powerful entertainment platform that not only meets current needs, but expands to meet tomorrow’s needs as well.

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 existingframes 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.

10-bit Processor and 10-bit Panel

deep color eliminates visible color banding 10-bit color While it’s great to state that a TV is capable of creating billions of colors it’s a whole lot better when you have a true 10-bit display that can actually display them. Sony combines 10-bit processing with a 10-bit panel, allowing 64 times the levels of color expression. What that translates to is smoother transitions from color to color and subtle color changes faithfully reproduced without a paint-by-numbers look.

So, where x.v. color expands the available range of colors your HDTV can display, Deep Color increases the number of colors your HDTV can display within that range, for smoother transitions from color to color.
  • Lets HDTVs and other displays go from millions of colors to billions of colors
  • Eliminates on-screen color banding, for smooth tonal transitions and subtle gradations between colors
  • Enables increased contrast ratio
  • Can represent many times more shades of gray between black and white.

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.

Digital Living Network Alliance (DLNA)

DLNA logodlna daisy chainAll 2008 XBR and Z-Series BRAVIA HDTVs are DLNA-compliant.

You already know something about digital living. There’s the TV and digital video recorder in your family room. (And another set in your bedroom.) You have a PC and digital printer in your office, along with a network attached storage device. And you’ve copied all your music onto your portable music player and haven’t had to open a CD case for years. But getting them to talk to each other can be pretty tough. Why is it still so difficult to send digital content from one device to another?

Digital Living Network Alliance (DLNA) is a collaboration of the world’s leading consumer electronics, PC and mobile companies that has created design guidelines for a new generation of products that can work together — no matter the brand.

Think for a moment about all of the photos "locked away" on your home PC that you wish you could access while entertaining your friends and family. Now, thanks to DLNA enabled devices, a DLNA-enabled PC can be accessed from the comfort of your living room or family room via a DLNA-enabled HDTV, where you can enjoy your memories with friends and family, without having to deal with the hassle and non-intuitive "PCexperience".

Or, say you recently downloaded your daughter’s birthday party video from your digital camcorder to your PC. Now you want to share it with your parents who are visiting. Without DLNA, you probably have to burn a DVD of the video or hook up the camcorder to the TV. With DLNA, you can just use your TV’s remote to call up the video on your TV. That’s it.

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.

Color: Silver Verified Purchase
I have had a Westinghouse 1080p 42inch monitor for a few years and have really been pleased with it. However, with the new features on the market (120hz, 24p, etc) I was ready to upgrade. I initially ordered a Samsung LN46A550 46-Inch 1080p LCD HDTV. The picture was actually really good on this set, but the glare on the case was VERY annoying. It also lacked the features I was looking for in a new set, but I tried it out because the price was so good. The glare was too much to put up with, so I sent it back and started to research Sony's since they are one of the few sets on the market that you can still get without a glossy case.

I sure am glad that I found Bravia Z series! WIthout going up to an XBR, the Z series is the way to go. If you look at the specs - most of the high end features offered by the XBR are already in the Z series, so it is a really good value when viewed that way. It makes sense why the Z is not offered in a 52 inch size - it would probably really impact sales of the XBR. What a great looking TV (both the picture and the case). I have been extremely impressed with both the blacks on this LCD as well as the vivid colors it produces. The amount of picture calibration offered on this setup is remarkable - especially compared to my old Westinghouse. I find the 24p mode on Blue Ray disk to be quite impressive - it really adds a whole new level of enjoyment to watching Blue Ray movies. The 120hz mode is also wonderful when watching football. I really cannot say enough good things about this TV - spend the extra money that the Sony brand demands, and you get what you pay for.

Although I did not have the issue with this TV, there is a lot of discussion around the Internet about a sparkle issue that this TV has.

Color: Silver
I decide on the 46z4100S for the following reasons;

a) No glossy screen glare or bezel glare!
b) small bezel, allowing larger screen on wall space
c) 3" depth on "in-wall mount"
d) 1080P/120HZ/motion control

The Picture Quality is so crystal clear......... just great! Bright, vivid colors are awesome! There are so many features and very easy to set-up.

My wife loves the brushed metal and says, "it doesn't have glare, doesn't look like those 'black plastic' frames". She's candid(LOL) and loves the amazing PQ, when watching her baseball games.

I'm using an in-wall mount and the 3" depth makes it look like a picture on the wall. The "46Z" is perfect from a viewing distance of 9-11 ft. Friends all love it!

I'm still making the viewing adjustment from a 27"CRT floor console. My eyes do more tracking on this larger screen.

Color: Black
I had been researching TV's for about a month or so. I knew I wanted an LCD in the 42"-50" range, backed by a trusted brand name, with if not cutting edge technology then at least most of the latest and greatest features on current high-end models. This because a TV is something I buy and use for many years, and I don't want my set to become obsolete two years from purchase date. So after reading many product specifications, manufacturers' descriptions, reviews from other users and professional reviewers, and spending many hours walking through electronics stores and looking at displays, I picked the Sony Bravia KDL-46Z4100. The next closest contender was the KDL-46W4100. However, the Z series won out, although it was a couple of hundred dollars more expensive, for these reasons:

- Much better looking set (I'm talking about the physical TV here) with a very slim bezel and all-black design, as opposed to the two-tone black and silver of the W.
- 10 bit color processor, which gives far more on-screen colors. I didn't think this was a big deal, until I saw a W and Z series side by side in a store, and the display happened to show a sunset. The W had distinct bands of color, while the Z had a gradual change of color.
- DLNA. I don't use this option yet, but it's nice to know that I can if I want to. I have a PS3, which also has DLNA, and I use that to beam images/music/video from my computer to my TV. The reason I use the PS3 is because its DLNA capability is wireless, while the TV's is not. This is an important caveat for those to whom the TV's DLNA capability is important. There are ways to make it work wirelessly, like hooking up a bridge, but I have not tried that. However, just know that out of the box, the TV can't do wireless DLNA.

Color: Black Verified Purchase
Many folks are going for the samsung lcds because the blacks look blacker.
but those tv's have a glass screen that reflects everything. This tv is sharper than a xbr4 or xbr5 , those were last years models. the engine in this tv is equivalent to a xbr6. I replaced a great 50 inch sony sxrd
tv with this one. Sony's newer 52's didn't have all the features of this one. the s, v, and w's are fine tv's but they don't have deep color the new color standard that future discs will have. Nor do they have x.v. color which is here already and is used in digital photos. this one does. the w does have 24fps or film speed that words with a ps3 or blu ray player to show a movie in it's real speed. Of course this isn't a benefit for older dvd's as they are processed in a 2:3 rate anyways. that means that one frame is dropped for every 3 shown. but for blu ray this feature rocks. And like ALL lcds standard non hd tv looks ok but they don't put standard tv on in showrooms. so people take these tv's home and expect it to look like HD content. this is true for all lcds, plasmas , lcos , dlp's and the rest. But this tv shines with hd content and blu ray. However, I will miss the extra four inches of screen. but this tv is in many ways future proof for a while. the 120hz feature for motion and other features make it one of the best tv's made so far. The toshiba 540 and 550 series are comparible but this tv is the clearest of the new tv's. xbr 7's will come soon but they will be much more expensive. the jump in size from 46" to 52" is also a substantial jump in price. So I can live with a 46" tv with this quality. This tv took 2 days to get to denver. which is great! I picked it up myself as the box and tv are not too large and this means I don't have to hang around waiting for a delivery.
