Dolby Home Theater v4 is, as the name suggests, the fourth-gen implementation of sound enhancement for PCs from Dolby Labs. It incorporates trickle-down technology from Dolby Volume (best known for its use in surround receivers) including volume leveling, dynamic enhancer, and spatial virtualizer. First of two demos at the Central Hall sanctum involved a laptop with and without DHTv4. It was a huge difference: muffled sound versus rather bright sound. In the second demo, another laptop bitstreamed into an Onkyo receiver with Focal sat/sub speakers. This time the benefits were more subtle, though still discernible: a larger soundstage and more solid imaging. The technology will be shipped with laptops including Acer, Lenovo ThinkPads, and more to be announced. In another corner of the Dolby booth a Nokia N8 smartphone with built-in Dolby Digital Plus (a high-quality lossy surround codec) mustered pretty good surround via Harman Kardon receiver and Focal floorstanding speakers.
An intriguing part of Sony's enormous booth in the Central Hall discussed the "Monolithic Design" philosophy, which gives Sony Bravia TVs a commanding "on/off presence" -- in other words, they look cool whether the screen is active or dark. One aspect of the philosophy in action is a six-degree tilt that suits "low, contemporary furniture."
You'll probably read some blogs from our two-channel colleagues about The Sonus Faber, a fridge-size floorstander selling for $200,000/pair in a limited production run of 30 pieces. Playing a solo cello recording, TSF mustered some of the best sound at the show. But there were also brand new home theater worthy models at Sonus Faber's suite in the Venetian, namely the Toy Monitor Grand (center) and Toy Wall (upper righthand corner). They're sold in pairs, for $2,000 in both cases, but you can add the Toy Center for $995/each.
I normally would have enjoyed viewing this 84-inch LG LCD/LED 3D 4K set immensely (though it's not yet an available product). It enables full 2K 3D with passive glasses. But dropping my camera, resulting in serious damage, sent me scrambling to the Canon booth to see if they recommended my having it repaired (not at the show, of course). They did not. I needed a new camera anyway. Fortunately, with three days of the show left, I had brought along a spare.
Here's a way to encourage your kids to write on the wallthat is if the wall is an LG Touch TV which functions like a huge, modern-day, multi-colored Etch-A-Sketch. It's also a 2D plasma HDTV. But it's clear that not all of us are Rembrandt.
While I don't have a great shot of Sharp's XV-Z17000 DLP 3D projector, it looked bright and beautiful on a 100" screen with a stated gain of 1.0. It was clearly one of the best 3D projectors I've seen so far, and also the least expensive at about $5000.
A trip back to the Toshiba booth will be needed to get a look at Toshiba's demo of glasses free (autostereoscopic) 3D. The crowds waiting to see this technology were huge. Still, I think all the hoopla about 3D without glasses is going to leave a lot of people disappointed. I suspect that it will either be years away (if it's ever perfected at all—not all technical challenges have a ready solution) or a serious step backwards in image qualitywhether from Toshiba or anyone else. But I could be surprised. A similar demo from Sony, while hardly flawless, looked better than I expected.
No model number, price, or availability date was given for this Samsung 27-inch PC monitor/3DTV combination. But it can handle all 3D formats (the image on screen shows the side-by-side format in its native form before it's processed into a single, unsqueezed 3D image. The display includes an antenna input (it has a built-in tuner) and an HDMI port. You will need active glasses to watch 3D on it (it is not autostereoscopic).
No price, delivery date, or model number was offered on Samsung's 3D DLP video projector. It didn't look all that good, but possible culprits include the highly variable program material, the fact that the side of the booth opposite the screen was open to the well-lit show floor, the 3.0 gain screen (don't move off-center!), and seriously blown-out whites. But it did look much better than this prize-worthy photo.
