The Vizio XVT423SV 42-inch LCD offers 1080p high-definition resolution, a 240Hz refresh rate, 5 millisecond response time, built-in Wi-Fi, and many connectivity options. Good picture quality gives this TV a leg up against the competition, but audio quality is only average at best.
The Vizio XTV423SV's design is fairly standard, with a shiny black bezel on a non-adjustable stand. In total, the TV measures 40.6 x 3 x 27.7-inches (wdh) and weighs just under 38 pounds.
The remote control for the unit is quite wide, but has small-sized buttons, which we didn't like. The four-way navigation pad is in the form of a sleek-looking diamond shape, while the numeric keypad looks smashed together and is too small for people with large fingers. It also, however, has a slideout keyboard which is also plagued by small, uncomfortable keys.
This TV is well-connected, meaning it has a large selection of ports. The side has three USB ports and 1 HDMI in. The back ports that face downward include 4 HDMI ports, VGA-in and a cable/antenna. The back ports that face outward include composite in, audio out, digital optical audio, component video, Ethernet in, and a PC audio in port too. The ports are rather comically labeled "Best, Better, and Good", where HDMI is labeled "Best" and the component video ports are labeled "Better."
When first turned on, you'll be asked to setup the TV by first allowing it to "connect" to the remote by a rather strange press of seemingly random buttons, but you only have to do this once. The wizard then moves through setting up your cable signal, any connected devices, and then Internet connectivity. Setup worked well and was a breeze. The on-screen menus throughout the TV are well-designed and look pleasing to the eye. Vizio allows you to adjust all of the possible video settings on all other TVs as well as allowing you to adjust the quality of streaming media, which is a rarity. You can also choose from preset picture modes, which include Standard, Game, Football, Golf, Movie, and a few others. Some advanced features are also included which gives added image customization, like noise reduction.
Some of the specifications of this TV include a display resolution of 1920 x 1080 (1080p) with HDCP support, a native aspect ratio of 16:9, a pixel response time of 5 milliseconds, brightness of 500cd/m2 and a viewing angle of 178 degrees.
Vizio calls this TV "fully connected" and it is connected by either Ethernet on the back or by its built-in Wi-Fi, which is a plus because some TV's require you to use a USB adapter for wireless connectivity. Vizio pre-installs several Web applications, including Netflix, Flickr, Facebook, Twitter, Yahoo News/Weather/Widgets, TV guide, and more.
The viewing angles on the Vizio XVT423SV are excellent and are rated at 178 degrees, which is almost 100%. In subjective testing, the TV displayed good to very good-rated image quality, with only slight blurring across fast-moving image elements. Color accuracy and brightness were very good, even in darker scenes where some other TVs lose detail.
Audio quality, on the other hand, was only mediocre. The quality seemed a little "tinny" and a little unbalanced in terms of tone levels. You can turn on TruSurround sound for added depth, but it didn't seem to do much in the end. The speakers are mounted right under the display on the front and are 15 watts each.
