Sony Bravia KDL-46HX820


Sony HX820 series information: Our review of the Sony KDL46HX820 is based on our time spent evaluating the 55-inch KDL55HX820. According to Sony, the two sets differ only in dimension and weight and offer identical features and performance.

Excellent black level and contrast ; Very bright white levels ; Slick, flat panel with darkened, anti-glare glass ; Built-in Wi-Fi, plenty of Internet apps ; Quick network media access

3D glasses not included ; Remote not backlit ; Unnecessary processing adds expense

Is the added cost of the non-XBR HX series TVs worth it? There may be isolated cases where it is.

Sony Bravia KDL-55HX820


The Sony KDL-55HX820 is a notch below Sony's top-of-the-line HX929, but it boasts many of the high-end features. The KDL-55HX820 boasts 3D and WiFi, the latter of which offers Sony's new premium suite of content, Qriocity. Top off that package with...

With built-in WiFi, 3D, and 480Hz, the KDL-55HX820 has all the trappings of a high-end set. The problem we have, however, is the TV is almost indistinguishable from other units in Sony’s line-up. Almost all their series feature WiFi and 3D. The only...

A scientific, in-depth analysis with side-by-side comparisons

The Sony Bravia KDL-55HX820 is a high-end 3D LCD TV with a price tag to boot, but is it worth it? It has all the streaming features you could ever want in the year 2011, but who knows what the future holds; today’s Qriocity might be tomorrow’s...

Sony BRAVIA HX820 review: A 3D LED TV with excellent picture quality and a built-in Web browser


Sony's high-end HX820 BRAVIA LCD TV uses a great LCD panel and can look excellent after adjusting the picture to suit the room it's in. Some of its Web features fall flat, like the Web browser -- which isn't as easy to use as Samsung's -- but the...

Great picture quality once adjusted, Deep black levels, Video-on-demand selection is diverse

Requires some picture adjustment to look its best, Some Internet features aren’t easy to use, Front glass is very reflective

highly recommended over the NX720 Design is main comparison to the HX820. Very short brightness setting from dim to bright on the NX720. XR pro works well with 240hz & HD for youtube.

Sony Bravia KDL-55HX820


I have the KDL-55NX720 hanging on my bedroom wall and I just love it. Of course the sound quality is very low. That is why I have it hooked up to a Dennon reciever and 4 front Kplish speakers 2 surround speakers and a 10 inch bass cabinet.
