  • Good TV, Terrible Remote
    Reviewed by AAAA - April 18, 2021

    the tv is good for the most part. 4k and color is pretty much the same as last year's models, little darker maybe. when the screen is on but all black there are random grey areas, uneven panel possibly. 120htz functions. the remote is horrendous. this solar charged remote is junk, i've had the tv for about 3 weeks and had to charge the remote 5 times, it's not much but still 2 batteries would last way longer. buttons suck,wanna watch tv? it's up to the remote to decide if it will let you (power button works nothing else will). overall the only reason i got this thing is for 4k 120htz gaming and half the time i can't use it. not worth the money.

  • Good TV, not great. Definitely could be better.
    Reviewed by Saub - October 6, 2021

    [This review was collected as part of a promotion.] I bought this TV 3 months back. Overall it does the job, but I won’t rate it to be the best. Specially from usability perspective. UI can definitely be improved. Using arrow keys in the UI is premitive. Typing a YouTube search keyword is so cumbersome. LG does lot better job in terms of UI. Plus the remote - solar powered remote runs out of juice so often. We gotta keep charging it every week almost. Plus wall mounting it was also a pain. Just don’t use Samsung’s wall mount ever! So overall it does the job, but it’s definitely not a great product. And am sure these problems persist in other models as well- the UI is Same across all models.

    No, I would not recommend this to a friend.

  • Awesome TV for the Price
    Reviewed by TyFighter1 - September 14, 2021

    [This review was collected as part of a promotion.] I bought my Samsung tv for gaming mainly but I use it for streaming and movie nights as well, the picture is wonderful and it starts up super fast!! The best part is thanks to it's smart features it automatically detects what devices I have hooked up, be it an Xbox or Playstation or even my PC. The 4K screen is crystal clear and makes watching Netflix so much better. Even lower resolution shows are upscaled to look even better. And when I'm not using my TV for anything the ambient mode makes it match the rest of my room decor and it looks like a picture I've hung up. All in all it's an awesome TV and I don't see myself using another brand.

  • Life-like, Vivid Crisp Clean Picture
    Reviewed by DGolfSun - April 7, 2021

    [This review was collected as part of a promotion.] I have the huge TV mounted to the wall on an adjustable pull-out arm that can swivel 90° to the left & to the right. My guests that haven't seen !y setup are amazed at the picture quality. Example if I have a PGA Golf Tournament on I get comments that people feel like they are actually there and they feel like they could step onto the grass by how crystal clear and plush the screen picture quality is. All the comments are to where how life like and the feeling like your are there at the event on the screen. I'm looking forward to getting the 8k at least 80+ inch screen soon to go with my new Home Theater 11.3.6 Channel Klipsch Surround Soumd System

  • The upgrade we needed!
    Reviewed by Anonymous reviewer - June 23, 2021

    [This review was collected as part of a promotion.] This TV is definitely a game-changer compared to our last TV. Installation was quick. The updates Samsung has made since we last bought a TV are noticeable and very much appreciated. Picture quality is much better (with the exception of one dead pixel). TV actually lets us make the most of HD shows and higher pixelated console games. The controller has a voice command option which we found pretty cool and straightforward. TV also has a split-screen feature which we're still playing around with but we like the fact it's even an option. Like most newer Samsung TVs, our TV allows us to easily pair our Samsung phones through smart view.
