Panasonic’s CX800 series of ultra high-definition (UHD, or 4K) LED-backlit LCD HDTVs boasts a stylish design, and a very user-friendly interface based on the Firefox OS. It’s certainly a very attractive and functional line of televisions, but performance lags a bit behind the competition. 



  • The CX800 can be coaxed into being remarkably bright and producing very low black levels, but not at the same time. That means the 432.31cd/m2 peak brightness and 0.01cd/m2 black levels we measured separately at different settings and different conditions are not the best indicators of the screen’s general performance. After a basic dark room calibration and using a contrast tunnel to record black level, we measured a peak brightness of 308.35cd/m2 and a black level of 0.29cd/m2, for a disappointing 1,063:1 effective contrast ratio. The HDTV is capable of performing far better at extreme brightness or darkness in isolated cases, but it simply doesn’t perform well in terms of what it can display on the screen at once. In the same test, the much less expensive Sharp LC-55UB30U showed a slightly dimmer peak brightness of 271.15cd/m2, but made up for it with a far superior 0.07cd/m2 black level, for a 3,874:1 contrast ratio.

Design of Panasonic’s CX800 series

  • The 60CX800 looks simple but attractive, with a flat, silver-colored metal bezel that runs around the screen, measuring 0.4 inches on the sides and top, and 0.6 inches on the bottom edge. The screen sits on a large, skeletal U-shaped metal stand that holds the set up securely, but sticks out nearly six inches in front of the screen, which could make Blu-ray player or game system placement on the same surface slightly awkward; you might need to move your media player of choice a bit to the side rather than directly in front of the screen.n HDMI port, three USB ports, and an SD card slot face left on the back of the screen, and two more HDMI ports, an optical audio output, an antenna/cable connection, and an Ethernet port face down. A component/composite video input faces directly back. The presence of only three HDMI ports is underwhelming, when most midrange HDTVs offer four. Power, Volume Up/Down, Channel Up/Down, and Input/Menu buttons sit on the right side of the back of the HDTV, recessed and slightly difficult to reach.
  • Panasonic includes two remotes with the CX800. One is a conventional, button-laden wand with a prominent direction pad and a dedicated Netflix button. The other is a small, cell phone-shaped touchpad. This remote is built around a rectangular, textured rubber touchpad flanked by membrane buttons above and below. Home, On-Screen Remote, Voice Search, Volume Up/Down, and Channel Up/Down buttons sit directly above the touchpad, and a direction pad, Favorite, Return, Guide, and Menu buttons sit below it, along with four conventional color buttons. The Power button, along with a hole for the built-in microphone, sits at the top of the remote. The touchpad felt very sluggish at first, but increasing the sensitivity to Strong made menu navigation and cursor control feel much more responsive.


Firefox OS

  • Panasonic is using Mozilla’s Firefox OS as the core of the CX800’s interface and connected features. It’s a bright, colorful menu system, visually similar to LG’s WebOS HDTV interface. It supports Netflix (including Netflix 4K content), YouTube, Hulu, Vudu, and most other major streaming media services, along with a wide selection of social networking, news, weather, sports, and other apps. A Mozilla-crafted Firefox Web browser is, of course, also built into the system.
  • The Home menu initially only displays three options: Live TV, Apps, and Devices. However, you can pin any channel, app, or source to the menu to keep them at close reach; the Options button lets you pin items to the Home menu and rearrange them. Xumo, a suggestion engine and content guide, is accessible by holding the Home button down. It highlights popular and trending movies and TV shows, and offers suggestions on what to watch through on-demand video services like Vudu and CinemaNow based on what you currently watch. However, it’s much less useful than a guide that includes live TV, and is pretty forgettable.


  • PROS

    Minimalist, attractive design. Firefox OS-based interface is full-featured and easy to use. Good color accuracy.

  • CONS

    Poor effective contrast. Expensive for the performance it offers. Only three HDMI ports.
