>> David: David Katzmaier here from CNET. I'm with the Vizio VF552XVT; this is a 55 inch member of Vizio's 2XVT Series. There's also a 47 incher in this series that this review applies to. The 42, however, is not quite the same backlight technology so it is not included in this review. All 3 sizes share Vizio's interactive apps functionality. We'll get to that in a second, but first a little bit about the styling. This 55 incher looks different from the 47. It has this speaker bar along the bottom; this silver kind of bar. We're really not huge fans. It kind of makes the TV look a little bulky. And if you turn it to the side you can see it's actually thicker than a lot of the other LCD's out there at 5 inches. We really don't care about that but we would like to see Vizio include a swivel on the stand. The 47 has a slightly different styling with a little bit more silver on the bottom but all told these really aren't the slickest looking TV's on the market. What is slick, however, is the Vizio interactive apps platform; this is kind of like supercharged Yahoo widgets. So you press the apps button and up comes this bar along the bottom where you can see a whole bunch of different apps which include Netflix, Rhapsody, Facebook, Pandora as well as weather widgets, ways to check eBay and a host of other functions, and, of course, Vizio's adding more. We really like the speed of this interface. It just zips along compared to Yahoo widgets. And Facebook and Rhapsody, for example, are 2 apps you won't find on any other TV, so great content there. But the real killer on this TV is the remote control. You can actually flip it open and you get this full QWERTY keyboard sort of like you see on a smartphone, and that enables you to enter, you know, login information, you can tweet from it, you can update your Facebook status really easily with this thing, so the remote really is a great feature and really helps people who are into this Internet on TV functionality. One other capability on this remote is Bluetooth so it can actually operate without having line of sight to the TV. It can also, perhaps, get some future functionality upgrades maybe controlling the TV with an iPad or whatever else Vizio dreams up. Speaking of wireless this TV has built-in WiFi as well, although in our testing it didn't work quite as well as the wired Ethernet connection. Other features on the Vizio include excellent connectivity. The back panel has 4 HDMI inputs on the 55 incher and just 3 on the 47 as well as a PC input and Ethernet port and 1 component video input. The side panel has 1 HDMI input as well as 3 USB inputs that are currently inactive. Picture settings on this TV are relatively comprehensive. You will find the ability to play around with color temperature and a couple of other settings including the local dimming but all told it doesn't have as many picture tweaks as a lot of the other high-end TV's out there. We mentioned local dimming; this TV does have full array LED local dimming back-light that trumps the performance we've seen on most edge-lit displays as well as standard LCD's. It doesn't quite match these deep, deep blacks we've seen on some other local dimming LED models including Vizio's from last year but all told it's pretty darn good. Vizio's color accuracy is slightly worse, again, than some of the other LCD's we've seen. It does have a slightly greenish tinge to some of the mid tones that we really couldn't get rid of despite the picture settings. There's also a little hiccup with the 1080p 24 capability. It's not, again, quite as good to video file ives [phonetic] as we've seen but all told the picture quality in this TV is very good especially when you consider the price. That's a quick look at the Vizio 2XVT Series and I'm David Katzmaier.
