Sony KDF-55XS955 55-Inch HD-Ready LCD Projection Television Review

I've had this TV for about 2 months now. I've connected an HDTV cable box via HDMI, progressive DVD player via component input and TIVO through S-video. So far the TV has performed extremely well, no problems to report. I've also been very impressed with the sound this TV produces. It's so good that I don't normally bother to run normal TV through my AV receiver.
Standard definition looks better than I expected for both straight cable broadcasts and through the TIVO recorded on medium quality. DVD look very good, but the true HDTV sources really shine with this TV - the Olympics were amazing!
The display is bright enough that I actually watch it with the bulb in "reduced" mode (even in the day) to extend the bulb life.
I've had no problems, and as suggested for anything projection systems I've got the TV hooked up to a UPS in case of power failure, and I did spring for an extended warrantee with bulb replacement.

Go for gold with Sony's stellar, 55-inch KDF-55XS955 rear-projection LCD television. The big-screen, flat-panel set delivers standard and full-fledged HDTV reception right out of the box through its integrated NTSC and ATSC (HDTV) tuners. It also offers digital cable readiness with a CableCARD slot and the latest digital-video interface, HDMI. Weighing a mere 105 pounds and standing just 19 inches deep, the set also offers maximum image with minimal space investment.The set's 1,366 x 788 liquid-crystal display frees you from having to make convergence adjustments or having to worry about image burn-in. Instead you get incredible detail (more than 3 million pixels), high contrast, and even, corner-to-corner brightness from the set's user-replaceable 132-watt UHP (ultra high pressure) lamp.The screen features a wide, 16:9 aspect ratio to match the dimension of most movies and HDTV broadcasts, and the KDF-55XS955 offers compatibility with standard-definition 480i, enhanced-definition 480p, and high-definition 720p and 1080i signals.Sony's CineMotion 3:2 pulldown detection and reversal is a handy feature for watching progressive-scan movie programs in their native 24-frame format. Digital video mastering introduces a common distortion when adjusting 24 frames-per-second movies to 30 fps video; 3:2 pulldown digitally corrects this distortion, removing the redundant information to display a film-frame-accurate picture.The set's WEGA Engine system maximizes picture performance from any video source by minimizing the number of digital-to-analog conversion processes. This full digital processing engine includes Sony's MID-X (Multi Image Driver), which maintains the integrity of a converted signal by minimizing image loss in the scaling process; and a proprietary optical engine, which employs a trio of Sony's wide-XGA, high-resolution LCD panels, 1 for each of the RGB signals (resulting in a total of 3.28 million dots of resolution).The optical engine also features a special 11-element lens system responsible for the lightweight, ultra-slim cabinet. The lens system bends the light path, creating an ultra-short focal point while maintaining high brightness. This proprietary system delivers vivid images from the center of the screen all the way to the edges.This XS Series Grand WEGA television offers advanced menu functions that are typically found only in service menus: gamma correction (bright and dark balancing), black correction (enhances contrast), white balance (fine-tunes white intensity), detail enhancement (sharpens the picture), and clear white (emphasizes whites).The set includes numerous other features.
TwinView PIP (picture-in-picture) lets you view any 2 sources simultaneously, even at different image resolutions, while the built-in Memory Stick media slot offers ready display of both JPEG images and MPEG-1 video.
A Memory Stick media slot (compatible with Memory Stick Pro and Memory Stick Duo media) grants convenient viewing of JPEG and MPEG-1 files. It can also display customized slide shows using MP3 files for background music.
Authorized CableCARD ability means the set will receive digital cable television systems services directly from the cable operator without requiring a bulky, external cable box.
Live Color is an innovative circuit that emphasizes blues and greens without affecting reds for a more natural, vivid picture. Choose from 3 enhancement levels (high, medium, low) or "off."
Sony's exclusive S-Master 1-bit digital amplifier produces 5 watts per channel (x 2), pumping an additional 20 watts into a built-in subwoofer for rich, full-bodied sound from movies and music.
HDMI (High-Definition Multimedia Interface) is a lossless, uncompressed, all-digital audio/video interface to link the set with any audio/video source (such as a set-top box, DVD player, or AV receiver).What's in the Box TV, remote control, remote batteries, a user's manual, and warranty/registration information.

I nearly pulled the trigger on a Samsung 55" model but while chasing the cheapest price, ran across this LG at Best Buy for $1799. Detailed info is hard to find, but it was available for store pickup so I took a chance without seeing it first since I could return it easily. I am glad I did. I cannot imagine a better picture. Observations:
Container is 56-1/2" x 40" x 21" with 2 hand holds on each end. Two adult males handled it without much difficulty. Comes with stand attached. Clip the bands, lift the bottomless box up and put it where you want it. I did not, but plan on 3 people to wall mount it.
You are not going to get home theater audio out of any unit without a subwoofer. It is simple physics. This one sounds pretty good for what it is. You can easily connect it to a home theater system with the Digital Audio Out or RCA ports. It has no separate Subwoofer Out port.
I read an article that expounded on the limitations of the human eye to distinguish contrast at any one light level. Think of waiting for your eyes to adjust to bright or dark conditions. The point made is that contrast specs are BS. Test eqpt might measure another TV as having more range than this one, but I don't think your eyes would detect a difference. This TV has good black levels and maintains them as you crank up the brightness. I still think plasma has the best picture but can't live with its shortcomings. I question the benefit of LCD LED backlight beyond reduced energy consumption and a skinnier unit. Maybe it improves black levels?
If you have digital cable as a primary source, don't blame muddy dark areas on a TV. It is just excessive compression they use to save bandwidth. Sat TV is generally better. OTA broadcast is beautiful. Everything falls short of 1080P DVD. A gamma adjustment can help tweak this problem. This TV has some "expert adjustments" including gamma and black level. I haven't played with them, yet.
One of the imaging engineers I work with gave me a chart that shows the limitations of the human eye with respect to HD. Per the chart, you have to get a lot closer than normal viewing distances to see the difference between 480, 720, or 1080 resolution. This TV is big enough that it might matter to some folks and it looks great up close. I start to see the screen door effect at about a 24" viewing distance. Even with eagle eyes you would not see it at a comfortable viewing distance.
SD content looks very good but you can't make it HD. The interpolation algorithms work well. NTSC (the old analog standard, what you get from a VCR) is 320 x 240. Standard DVD is 480P. This is an area where you could see big differences between products.
TV's are moving toward becoming personal computers. I can see future units having a PDA for a remote and full capabilities. That will be cool. I can't wait. This one doesn't have any of that except a USB port for displaying pictures and playing music. It appears that computer capability is what makes a big difference in price. In my opinion, the most capable units are still pretty lame. This is the bottom of the line model but the only difference is the computer features. This TV has a PC port. Online streaming content is 480P, at best, and extremely compressed. I don't think it looks good on a big screen.
Menus are well designed. This TV makes it easy to optimize to your preferences. I did not like the "Auto" setting for picture brightness. I wanted it brighter. Otherwise, the initial setup wizard did the job.
No S-video. Seems like it is being dropped by the manufacturers.
I would like to have 2 antenna inputs but the only TV I found that has two is Mitsubishi.
Since broadcast frame rates are around 30 fps and interlaced only refreshes half of the lines, I think the effectiveness of 120hz (240hz)refresh rate is pretty subjective and content specific. Same goes for the 24 fps movie source stuff on DVD. This TV has settings for these features. If I find them useful, I will update this review.
I could gush awhile, but I think I will watch the TV instead. When you read other reviews that gush, apply them to this one.
Thanks to all of you who share your opinions and experiences with us. It helps a lot. For TV, even visiting a store will not help much because they do not optimize the picture and the store lighting is usually green. So the brightest one tends to draw your eye.
