Over a billion colors in motion

Equipped with Quantum Dot Technology, this TV unleashes a massive spectrum of a billion shades of color. It even looks great when you're not watching at all, thanks to Ambient Mode +.

A smarter, faster processor

Samsung's powerful 4K Quantum processor automatically optimizes the picture to deliver a more immersive experience.

Adjust to the mood of your content

Dual LED backlighting technology adjusts the color tone so you can watch it the way it was meant to be seen.

Catch every word without distractions

Background noise from your home can disrupt your viewing experience. Active Voice Amplifier analyzes the ambient noise and enhances the voices in the scene so you can hear the dialogue clearly.

Experience a full range of detail

Quantum HDR brings out the detail and contrast by expanding the range of color and detail beyond what's possible on HDTVs. The dynamic tone mapping of HDR10+ creates deeper blacks, more vibrant imagery, and picture that pops.*

Bring more than a billion colors to life

With 100% Color Volume*, Quantum Dot Technology delivers over a billion shades of color that stay true-to-life without washing out at any level of brightness.

Win more games, have more control

Experience enhanced gaming without having to make manual adjustments. With Real Game Enhancer+, extra motion clarity automatically reduces halo and blur in fast moving game scenes and AMD FreeSync reduces tearing and stuttering.*

See the picture, not the TV

A sleek, elegant, and minimalistic design from any angle draws you into the screen.

Beyond the black screen

Watch your TV virtually disappear into the walls of your home. Ambient Mode+ mimics the wall behind it and elevates your space by turning the screen into décor, artwork, pictures, or other visuals.*

OneRemote for total control

The sleek and slim OneRemote automatically detects and controls all compatible connected devices and content.

Spend time watching, not searching

Universal Guide provides a list of curated content from broadcast and streaming channels, personalized just for you. Easily find your favorite content, all in one place.

Second screen on your big screen

Multi View splits your TV screen in two, putting the content you're watching on one side, and mirroring your mobile screen on the other. Watch workout videos, check sports stats, and more while watching your favorite show or game.*

Choose your voice assistant

Quickly access favorite content, get answers, and even control your TV and other connected devices around your home.

Control your home with SmartThings

QLED works with SmartThings to put you in control of your smart home. QLED links with IoT devices and sensors so you can turn on the lights, check what's inside your fridge, and even run the robot vacuum cleaner right from the comfort of your couch.*

Huge upgrade!

Submitted by mimartin2013 - 11/19/2020

I upgraded from an LG SUHD 65' and it's a massive upgrade. The tv is amazingly smart and always keeps the best picture possible with the intelligent mode. Game Mode is a little meh, but only because it ALWAYS blacks the screen when going from game mode on to off back to on when going from game to game on Xbox Series X. The app selection is larger and greater than the WebOS LG app store. Connecting my Samsung TV to my Google assistant was extremely easy and made voice controls a breeze. Ambient Mode is the greatest thing ever. I leave it on during the night as a light source for midnight snacks and I love the soft background music it plays. Such a great deal and worth every penny.

Has obvious lack of black color in bright scenes

Submitted by Mikle - 11/9/2020

If you have any bright object in the screen and black area then the black will have neither uniform color nor it will be black - it has greyish areas and they are obvious on 85 inch screen Other than that it's good but it's very obvious drawback for such an expensive TV. Buy Q80 at least to avoid it

So worth waiting to buy!

Submitted by Evilriva - 11/7/2020

Been using old hand me downs from friends and family forever, and finally dove into getting a new TV. I spent a lot of time researching what I wanted and needed and eventually found this amazing TV. It greatly surprised me on every aspect of tech it has. The screen is amazing, it covers like every app possible for tv/video games/or channel navigation. My last TV needed either used a giant old channel changer, or one from my TV companies old clunky changers. Add in a sound board or other objects requiring a changer, you end up with a ton. This tv changer is tiny, with few to no buttons, but controls everything with ease. Attached to my internet ethernet, or wifi if wanted, it is able to deal with all downloaded videos with ease and look amazing. I can't say enough about this amazing TV.

Submitted by Nate - 10/21/2020

I bought the Q70 4K 85 inch and the Q80 4K 65 inch tv and they have been fantastic! The set up is simple and very easy to use. The picture quality is supreme. I've only owned Samsung TV's for years now because I never have any problems with them. I really like how easy I can air drop anything to both TV's. I'd recommend Samsung to anyone looking for something new. Still have my 55 inch smart tv from 6 years ago working like the day I got it. Keep up the great work!

Great TV! Samsung Does it Again!

Submitted by Luminary2015 - 10/11/2020

This is my 5th Samsung TV and needless to say I get impressed with every new TV I have purchased. The ease of use, features, picture quality and of course the size has made me a very satisfied Customer. It's a great addition to my home and an upgrade in my home theater room. The remote is very user friendly and having Alexa built in is a plus!

Great TV

Submitted by Paks - 10/5/2020

I bought a 65" Samsung a couple of years ago and was very happy with it so wanted to purchase another Samsung after I moved. I wanted the Q80T but the store didn't have one available. I went with the Q70T and really think I made the right choice. It was easy to set up right out of the box. The picture is amazing and the sound is surprisingly good. The available apps are easy to find and download and there are a lot of choices. I like that the remote as a Netflix button added. You can still put the Netflix app on the Home bar but I like having the option of it being on the remote as well. Having access to Alexa through the TV is a huge plus. Lastly, I love the relaxation app with the sounds and visual effects! It's a welcome feature. I plan to have this TV for a while but I will always look at Samsung products before considering anything else because the quality and advancements never disappoint.

The TV is great!

Submitted by Daisy - 10/2/2020

We love the TV and have figured out how to work it. The only problem is that the Hulu app has to be rebooted sometimes or it doesn't work. We depend on the Hulu to watch this TV because of where it's located. It isn't on cable. Why does this happen? Otherwise it's great!

Great tv but has issues.

Submitted by 19DeltaVET - 9/18/2020

My Tv has a really nice picture but the edge lighting issues. The tv has a lot of visibly gray more so than what I saw in the store. I think I may have a defective tv. I study TVs and understand that tv isn't going to be perfectly black but this is visually annoying and very noticeable. I think the tv needs to be calibrated @ least or replaced @ best. The remote has more lag than my other 3 Samsung MU90004K TVs. Also my QLED tv turns on the my PlayStation for no reason. I'm not even in the source menu and it activates the PLayStation. I love my tv but these issues need to be fixed. I take great care of my tech and really like Samsung products and this large purchase is one I was hoping to have a great experience with especially since it's my "Theater Room" tv.

This product has problems with MLB app

Submitted by BigSandyDan - 9/17/2020

I purchased this large screen tv to watch sports mainly MLB. The MLB app does not work with this model, it starts buffering after about 3 innings and continues to get worse until it finally stops and shows an error message. I am hardwired with Cat5 wire and have fast internet. I own about 5 other Samsung tv's and have never had this problem.

Submitted by Jojot9 - 9/15/2020

We were expecting what the picture as advertised, but it only shows the clarity when you use 4k. Also the 240 motion is still blurry when it comes to fast scenes.Some of the programs I watch still creates pixel motions. sound is acceptable but not as great. you would need an external speakers for good sound. overall, it is acceptable.

Submitted by JoelB - 9/15/2020

From day 1 we have been extremely happy with our new Samsung. The picture quality is excellent, especially when streaming 4k content. I especially appreciate the ease of use of the built in smart features. The user interface is very intuitive. Many of the apps I use came pre-installed, but the fact that I can easily download additional apps is huge. I'm a huge football fan and was able to quickly find and download the streaming app and watch games in 4k. This is an intelligently designed quality product we have enjoyed greatly!

Great TV

Submitted by Samsungfan - 9/15/2020

Very happy with my 85" TV. I upgraded from my 5 year old 75" this summer and it's a world of difference. The built it apps work flawlessly, I have HBO Max, Disney+, of course Netflix and Amazon Video. Video quality is great and there are no artifacts in high action scenes like with my old TV. The TV is actually a few lbs lighter than my 75", I was able to use the same mounting brackets. The newer remote took a bit to get used to, but it is a true universal remote, it connected to my stereo and my cable box at the first attempt. My old TV was never able to control my stereo system.

I wanted to buy a projector but changed my mind and went with the TV and have no regrets. The sound quality is great. I am also thrilled with all the Apps which come with the TV. You dont need any thing else just the tv and an internet connection and you are ready to go.

Submitted by Drude - 9/15/2020

The picture quality is stunning. Worth the cost vs the Q6. The 85" is a good size. Impressed with sound out of tv speakers. Normally sound is the worst. It is not as good as a full surround sound system but for what it is it is excellent. The features are great. It also has bar far the best apps available from a smart tv. I evaluated all manufacturers with apps and Samsung leads the pack. Well worth every penny spent. Wish they had a 100" available.

Submitted by Eamora - 9/15/2020

3 top things I compared it to other Brand TV's - Remote is very convenient to navigate as compared to other controller with many buttons and too complicated to go through apps and channels - Linking to other apps and downloading them is very straight through with ease - Crystal Clear with high resolution on many if not all of the high definition that you can not see your reflection or what's behind you when watching anything worth no distraction

The 85 inch tv is crystal clear and makes it seem as if the people are standing in the room. The color is realistic and vibrant. I have a large room with a wall of windows that sheds tons of light into the room. The picture is visible from all angles at all times of the day.
