SunBriteTV Signature Series SB-4670HD All-Weather Outdoor HDTV

Design and Features
Thanks to the use of LED backlighting, the SB-4670HD is much thinner (3.7 inches) and lighter (47 pounds) than the 4660HD (6.7 inches and 65 pounds). The powder-coated aluminum cabinet is available with a black, white, or silver finish, and is designed to prevent rain, dust, salt air, and humidity from compromising the interior components. Thin 1-inch bezels frame the 1080p panel, which has a non-reflective, anti-glare coating. This TV has the usual VESA mounting holes, but it doesn't come with a stand or a mounting kit. SunBriteTV charges an additional $75 for a tabletop stand and a whopping $465 for an articulating wall mount kit.

The SB-4670HD's ports are encased in a compartment at the rear of the cabinet, protected by a weatherproof door that can be sealed with two large thumbscrews. Here you'll find two sets of HDMI, component, composite and S-Video inputs, as well as a VGA input. While it's nice to have such a variety of legacy video ports, I'd gladly trade a couple of them for a few more HDMI ports. The compartment also holds a PC audio input, analog and digital audio outputs, a coaxial cable/antenna jack, and a pair of service ports including a single USB port only meant for technicians to access to repair or update the HDTV. The SB-4670HD doesn't offer any Web services or any networking options whatsoever, which is unusual considering its lofty price. The built-in 20-watt stereo speakers are quite loud and can be maxed out without distortion, but if you like booming bass, you'll have to add a separate (and hopefully similarly weatherproofed) speaker system.
Seven buttons on the left side of the cabinet control power, volume, channels, sources, and allow navigation of the on-screen menus. The SB-4670HD has four picture presets: Standard, Dynamic, Theater, and Personal (user defined). You can adjust Brightness, Contrast, Sharpness, Tint, and Color Temperature levels and tweak RGB saturation settings, but there aren't any advanced calibration settings that allow you to adjust white point or six-axis color levels.
The SB-4670HD comes with a slim, 7.5-inch weather-resistant remote with 50 small, round buttons that offer all of the standard HDTV controls. It also has dedicated Aspect Ratio and Favorite Channels buttons.

Performance
We measure peak brightness, black level, and color accuracy using a Klein K10-A colorimeter, DisplayMate test patterns, and SpectraCal's CalMAN 5 software. The SB-4670HD turned in a very respectable peak brightness of 403.65 cd/m² and a not-so-impressive black level of 0.078 cd/m^2. The bright panel is ideal for outdoor viewing, but direct sunlight will still make the picture hard to see. If you want to use your outdoor HDTV when the sun is high and shining right on it, you'll have to upgrade to the SunBriteTV Pro Series.

The chart above shows measured colors as dots and ideal colors as squares. As it shows, red, green, and blue were all consistently oversaturated, and white ran very cool. These aren't necessarily bad levels for an outdoor HDTV; just like with the 4660HD, the oversaturated colors helped punch up the picture for outdoor viewing, and didn't result in tinting or skewed skin tones.
I watched the Giants-Cardinals football game on a sunny Sunday afternoon, and it looked excellent. The turf at Giants Stadium was sharp, and the player uniforms were bright and well-balanced. Viewing angles were ideal, and the picture looked just as good from the sides as it did when sitting directly in front of the set.
The SB-4670HD turned in an input lag time of 37.8 milliseconds, which, like the Panasonic TC-65AX800U (37.5 ms), is very solid performance. Video input lag measures the lag between a connected video source and the screen refreshing, so it's more important for fast-paced video games than watching television. The HDTV's 120Hz refresh rate and 6.5-millisecond pixel response delivered smooth fast action video with no apparent blurring or ghosting.
Under normal viewing conditions, the 4670HD consumed an average of 92 watts. This is on par with other similarly sized HDTVs including the Samsung UN46F8000BF (88 watts) and the TCL 48FS4690 (90 watts). Most notably, it's significantly more energy efficient than the CCFL-based 4660HD, which used 215 watts.
Conclusion
The SunBriteTV SB-4670HD is a premium-priced 46-inch HDTV that doesn't offer much in the way of features. It only has two HDMI ports, lacks networking functionality and USB connectivity, and you'll have to pay extra for a stand. Still, it can do something that most HDTVs can't: endure the rigors of the great outdoors. Despite some color accuracy and black level issues, the SB-4670HD delivers a sharp, well-balanced picture that looks as good in the light of day as it does at night, and you can leave it outside all year.
