Panasonic 65” Class (64.5" Diag.) Pro 4K Ultra HD Smart TV 240hz-CX850 Series- TC-65CX850U

  • Studio Master Drive- Helps 4K TV’s reproduce more detail and richer, more natural colors during dark scenes
  • An advanced LED Backlight Design, DCI 90-98% Color Space, which produces a wider color range
  • Firefox© OS to ensure ease for you to access smart apps and content
  • Voice Assistant Pro allowing to operate your TV just by talking to it with a remote control
  • Netflix© Recommended TV


The Spectrum of Colors Using a special LED LCD panel capable of producing a wider color range, more than 98% of DCI standards, allows the Studio Master drive to deliver a more subtle, naturally toned color palette which, unlike most LCD TVs, still looks authentic in any scene.
Light is The Source LCD TVs aren’t usually very bright and this is due to the types of light they use. Super Bright Panels solve this problem via the new panel-driving system plus a panel structure that lets light through more easily resulting in a highly efficient backlight system.
The Contrast of Darkness LCD TVs usually create pictures with just a few lights all running at the same brightness, making it hard to deliver convincing black colors and sufficient detail in dark areas. Local Dimming Pro provides individual control over a large array of LED lights behind the screen, greatly enhancing contrast.
Detailed, Crisp Images from Any Source Dealing with the advanced smart features and 4K picture technologies we now expect our 4K TV’s to require enormous processing power. Cue the Quad Core Pro engine. This cleverly separates the smart TV processing from the picture processing, so the smart elements run faster and smoother while pictures look cleaner, crisper and more refined – regardless of whether the content is streamed, cable broadcasts, DVD Blu-Ray, or 4K video.
Vivid Colors Even in Dazzling Scenes Dynamic Range Remaster ensures brightness data that is compressed while shooting is restored during playback without losing color data and the images continue to be brilliant and vivid.
Seamless, Automatic Content Recommendations XUMO Discovery, intuitive interface seamlessly and automatically recommends a wide variety of VOD content, such as NETFLIX©, Amazon and Instant Video, to the user.
Quick, Intuitive Access to Just the Content You Want Thanks to Firefox©, "my Home Screen" will be renewed, as a single gateway to all the broadcasting channels, apps and connected devices. A new Firefox© OS-based home screen makes it easy to access the content you want with intuitive operation.

TC-65CX850U is rated 4.9 out of 5 by 9.
Rated 5 out of 5 by from This TV is phenomenal and Love it. I got this TV for Christmas gift a week ago. Only my disappointment is that; there is no built-in Camera to use Skype. May be I have a Panasonic TV with Camera Built-In and loving it. Except Camera, I totally like this TV. Picture Quality and the contents are best fit for me.

Rated 5 out of 5 by from Best Telivision I have ever used! I genuinely enjoyed this TV, This is the first 4k television I have ever bought and of course I was skeptical of how much better this would be than my older TVs but WOW!!!!! I can not go back to using a regular old HD TV of the past I am loving the future!! The difference is vast I have recommended this to a couple of my friends and I am even thinking about buying another one and giving it to my girlfriend as a gift. Everything was extremely easy to setup and looked good on all my systems (xbox, direct tv box, and PS4). thank you so much!! Extremely satisfied and would certainly buy another!

Rated 5 out of 5 by from TC-65CX850U You get what you pay for- HIGH QUALITY I currently own 5 PANASONIC TVs; this being my newest and largest. I replaced a 61" DLP projection TV that still works like new, but consumes 120W vs. 40W on this new set. The 4K picture quality is very noticeable over the 1080P of the replaced set. I watch MLB via an app, so this TV has everything I could ask for and more. Even better was the reduced price on that made me pull the trigger on buying this quality TV for Christmas, but enjoying it a little early!!! A MUST BUY IF YOU WANT A QUALITY TV AT A REASONABLE PRICE.

Rated 5 out of 5 by from so far so good It was shipped from california and delivered to my apartment in New York. The 4K quality is amazing. Smart TV works extremely good and the internet browser is operated under FireFox. Two thumbs up. My wife loves it, so do I. Works good with PS4. Apps are great. Highly recommended.

Rated 4 out of 5 by from What a Shocker I recently purchased the Panasonic TC65CX850U 4K- 3D television after much research and other brand comparisons. I was excited about the latest technology the company had to offer. But then my excitement turned to bitterness when I soon realized that this previously priced at 4,449.00, marked down to 2,799.00, doesn't even come with a couple pair of 3D glasses much less one. My Sony 65in 3D LED tv I just bought middle of last year came with 4 pair of glasses. A friend of mine who just bought Samsung 65in curved 3D 4k, came with 4 pair of glasses. COME ON PANASONIC!!!...You have this Amazing tv and I can't even enjoy all it's awesome features right out the box. Buyer accessories category carefully. BUMMER.

Rated 5 out of 5 by from Early Review I have had my TC-65CX850U for about 3 days and to date the product is superb. I have been working steadily through the picture options and will update with my settings when thats complete. So far i am running on Vivid and made some slight adjustments. But overall i couldnt be happier with the picture. 4K upscale excellent and when running 4K through Amazon. I am just watching over and over again its that good. The firefox OS is ok, had a couple of hiccups i run 2 DLNA servers so im testing it to the limits and had to do a reset with MP4's not playing properly but seems ok now.

Rated 5 out of 5 by from Straight from the director's mind! I was initially skeptical of this tv since I was unable to see it in a store setting. But being familiar with Panasonic's attention to the smallest of details I knew they wouldn't release a tv unless they poured their hearts into it. This tv goes miles beyond my expectations! Straight out of the box the THX setting was superb. Entering into the professional modes you find that you have a plethora of tools at your control. Not that much tinkering is needed, but having options for custom gamma control as well as a platform for HD gamma BT. 1886 makes shadow detail shine! On top of that the color management system is the best that I've ever encountered. On top of that, if you aren't in to the in-depth calibration scene, the on screen options detail what each setting does, and in some cases clicking on a setting will allow the display to use its own processing to improve the picture quality whether its color or dynamic range.
