I recently welcomed the SAMSUNG 55-Inch Class QLED Q70A Series into my living room, and let me tell you, it's been nothing short of a visual masterpiece. This TV is like the Picasso of home entertainment - a true work of art! ⭐⭐⭐⭐⭐ Love, Love, Love! From the moment I turned it on, I felt like I was in a quantum leap into TV excellence. The Quantum Processor 4K is like having a personal AI assistant for your eyes. It magically elevates every pixel to 4K perfection, making my old shows look like they've undergone a Hollywood makeover. And the Motion Xcelerator Turbo plus? It's not just a feature; it's a rollercoaster for your eyeballs. Exceptional motion enhancements up to 4K 120Hz - it's like my TV is doing CrossFit for its pixels. Now, let's talk about the Dual LED Backlight - because warm and cool are not just for weather forecasts. They're the dynamic duo of contrast, creating a visual symphony that's both cozy and cool at the same time. But wait, there's more! 100% Color Volume with Quantum Dot – a billion shades of breathtaking color? It's like having a TV that can paint with all the colors of the wind. My eyes have never been so grateful for this burst of color that makes everything pop like a confetti cannon. Quantum HDR? Yes, please! Going beyond regular HDTV is so last season. Now my living room is a visual wonderland, and I'm the proud mayor of Color Town. And then there's the star of the show - Alexa. She's not just built-in; she's practically hosting the party. I now command my TV like a boss. "Alexa, play my favorite show." Boom, it's on. "Alexa, dim the lights." Consider it done. My TV has become the ultimate wingman for my lazy Sunday afternoons. In conclusion, the SAMSUNG 55-Inch Class QLED Q70A Series is not just a TV; it's a visual love affair waiting to happen. The quality is top-notch, the features are out of this world, and Alexa is the cherry on top. If you're serious about upgrading your home entertainment, this TV is your one-way ticket to a visual paradise. Trust me, your eyes will thank you later!

I just moved to a new city and in setting up my new place to live, I decided that I was going to indulge myself and set up a serious home theatre. This screen is, obviously the centerpiece. I did a lot of research and it felt like this QLED television would hit the right balance of quality, size and price and it most definitely has. It's a gorgeous screen and the set up has it about 12 feet from my sofa so it literally feels cinematic! One thing I would suggest is that, if you're wanting to set it up for hardcore movie watching, dig through the settings and set picture mode to "Filmmaker Mode". It's stunning! I opted not to get a cable TV package here because I was planning on doing everything via streaming, so far, so good. My set up is an AppleTV 4K to handle all of the streaming with a stereo pair of Dolby Atmos capable HomePod 2 speakers which work perfectly for the room size. Now as to why I say "almost perfect" in the headline: What I really wanted (and, sadly, I'll never be able to get) is not a "smart TV". Since I want to be able to handle the streaming through an external device and have the sound running through external speakers, what I wish I could've bought was a stripped down version of this panel with no speakers and no "smart" features. Basically a very very high end large monitor. The TV is enabled with Alexa (which I don't use) and its own App Store (which I also don't use) and some decent speakers (which have never been used since I set up the system). I really wish TV manufacturers would make simple, high quality stripped down televisions with advanced picture settings but none of the rest of it. Now I'm going to go watch something 4K and loud!

We needed a new TV for our bedroom and this is just what we were looking for. We have a Samsung in our living room and wanted to stay with the brand as I like the channel line up and we are a strictly streaming household. The only part of setup that threw me for a loop was the remote. I had never had one that was rechargeable and had to be paired to the TV. So after a few minutes of not being able to get it to work I put it on a charger for an hour and came back to it well dummy me still hadn't read the instructions and didn't know it needed to be paired. Once I finally read the directions I was setup in no time. Love this tv

I purchased this to replace an excellent Toshiba 50" LED. I now have a Roku useable on my main screen so I wanted to go with a nice TV because I have started to watch more. Unboxing and setup took an hour or so. Be sure you use internet connectivity and get that whole process out of the way. One note; Amazon's specs say this screen weighs 36 pounds; product literature says 42. It is the bigger number. Two people will make things easier as you put the TV in place. After completing all of this I decided I would not wait to watch. That night I put in a movie for 90 minutes. I was suitably impressed. Picture needs more fine-tuning, but I did 2 things out of the box; set the picture mode to Movie, as even Standard seemed too bright. Then, set your color temp to Warm 2. Before I bought this, I consulted with my brother, who has 3 of these Q70 series TV's, including the 75" I watched. I wanted to understand what I was buying before I just jumped in, and 2.5 hours of experiencing his screen sold me. My space is smaller than his, so the 65" I bought is plenty large. We will see how things go as time goes on. I did purchase a 4-year protection plan. I also had a little time to adjust to Samsung's minimalist remote; it's not terrible. But I am a Logitech Harmony user, so I took the model info and had it all set before the TV arrived. It works flawlessly. I did note that the TV is smart enough that as soon as I power it on, it defaults to HDMI 1 where my Roku is connected, and powers it on. Cool. I also have a Polk soundbar. It isn't top of the line, but it is damn impressive for $100. I chose to connect via digital optical cable and am pleased. Right here on Amazon as well. The TV speakers are not bad, all things considered. But I was looking for more range and depth to my sound, and this delivers. I looked hard at a Yamaha too, who also make good stuff. Time will tell, and tonight I will run another movie. Lastly, I think Ambient mode is neat. It's like a screensaver for the TV, which I like to use as a safeguard against burn-in. Be away for 20 minutes or half hour, and the screen does power off. No problem with that.

I'm so glad I jumped on this deal and got the last one. I've had it for about a month now, and this television is perfect for my bedroom wall. Of course when you get a samsung Smart TV, you're getting the best! Easy setup and all the free Samsung TV Plus free streaming channels. I've only paid for cable/satellite for a few years of my life, and with this television and its app capabilities I don't plan to ever pay for television again. I have Roku and Amazon Prime, and those are enough to waste the rest of my life away watching television and movies, if that's what I wanted to do (which I really don't). It mounted right to my previous wall mount after I transferred the brackets from my 65" television, so install was easy-peazy. What a beautiful picture. Don't settle for cheaper televisions with terrible refresh rates from the bargain superstores, get minimum 120Hz refresh rate. The only thing this television doesn't have is the optical sound output that my previous television had to interface with my Samsung sound bar, but there are just enough HDMI inputs to handle that with an UltraHD Blu-ray player.

The TV was delivered sooner than expected. It was packaged well for shipment, and everything was received with it that should have been. When I set up the TV it had a small group of black pixels that were located in the center of the screen. This made it look like there was a fly on everyone’s face. I called Amazon and explained what the issue was. They were very helpful and arranged to have the TV picked up while they ordered a replacement. Great customer service, Amazon! The replacement also came ahead of schedule, and it’s incredible! It was easy to set up, and pair to a sound bar. Adding apps was also quick and easy. I ordered the 55” which is the perfect size for our living room. The picture quality is amazing. The TV has a thin frame (about half an inch wide) so you see almost all picture when watching. Colors are vivid and true to real life. The QLED is a bright picture and it’s almost like being there. The remote control is easy to use, and is solar charged, so no batteries. I would like to point out the problems with this TV, but so far, I can’t name any. If you’re on the fence about this purchase, go for it. You won’t be sorry.

I bought this tv about 3 years ago. I love it. Easy to setup and a great picture. It's the q70a. Never a problem. A great thing about samsung TVs is the matching soundbar. I bought the q700a, with the surround speaks. The whole thing is perfect. The samsung tv and soundboard are designed to work together, sharing sound processing features.. Together the sound is better than I could have imagined. It would be a mistake to get the samsung tv without a matching samsung soundbar.

I will literally never purchase a Samsung product again because of the abhorrent customer service I received, but lets start with the TV itself. This TV is terrible. The "smart features" make it nearly impossible to get the actual picture you want, trying to do everything automatically, when really it just messes with your devices. The specs boast 120hz 4k, but trying to get a playstation to actually output 4k was a nightmare, which took a lot of researching which led to really just disabling all the "smart features" you can find and tricking it into accepting the right resolution, but you can forget about the refresh rate. A note for the skeptical: I'm using all hdcp 2.1 compliant cables and everything you need to make sure of, I know what I'm doing, the TV does not. The apps frequently crash, probably because there are inherent memory issues with the TV's software. It will disconnect from the wifi and log out of services randomly, forcing you to do a hard restart of the tv (not just turning it off and back on again) then log back into everything using this cumbersome remote with no buttons you would expect from a standard remote. Very tedious. If the TV itself hadn't wasted enough of my time, Samsung support definitely doubled down. A spider somehow managed to crawl inside the TV and get between the backlight and the LCD, where it died, and there is now a permanent spider blocking my image. THIS SHOULD NEVER HAPPEN. A decent manufacturer would have this sealed, and this would not be possible. Of course, the only way to remove said spider would be to take it apart. Anyone online (it has happened to other people) will tell you that the manufacturer should cover this if it is still under warranty, which mine is, because again proper construction would never allow this type of thing to happen. When I contacted samsung was when the real pain began. First, I couldn't register the TV. The website kept telling me the serial number I entered in was invalid, despite it being perfectly valid and verified by multiple support people afterwards. I checked the entry meticulously, so much like the TV software, website broken. Then support people wasted my time for hours while I got transferred around to different departments, because apparently none of them thought it was their responsibility. A couple of line transfers, given a different number to call, told that this was something specifically to be handled by chat support (which of course didn't work until being told by additional support that I needed to use a different browser [than chrome?!?!]), only for chat support to give me yet another phone number, and so on... To add insult to injury, every one of these people were rude, all the while I was calm, polite, and patient, while they audibly just dgaf. I finally was able to get to a form where I could schedule a technician to come to my house. I picked one of the available dates, got an email 30 minutes later saying that date was no good and they moved it to a different day, with not even a vague suggestion of what time. Still, I was patient. After 300 reminder emails and texts about my appointment finally the day came and I got a call where the support person just says "Calling from samsung to let you know that your service window is between 4 and 6:30". All that I could get in was "4 to 6:30?" before they said "Thank you" and HUNG UP. With no point of contact I waited around, and a couple of guys showed up late, and when I opened the door they said "samsung?" and walked in right past me... I had to insert myself to show them what the problem was, which was the only interaction I had with them. They basically ignored me while they talked to each other and waited on hold, then sent a couple pictures, and then turned around and said "sorry, we can't do anything" and just started walking away...WTF I am appalled at the conduct of every samsung representative I delt with throughout this experience. Seriously, unbelievable. If you have any self-respect, don't subject yourself to their BS.
