    [This review was collected as part of a promotion.] In the world of network broadcasting, there is only one brand which I’m not allowed to mention in this review on the site. Supposed to say that I’ve only had monitors and television sets by that Japanese brand, since it’s what we used at HBO and NBC.
    On a whim I decided to buy a Samsung Smart TV a bit more than a year ago. My regular professional brand didn’t have anything on the market that met my needs, which turned out good for Samsung: the color quality, temperatures, resolution, motion and everything are just extraordinary on the Samsung.
    I appreciate the additional capabilities of having a television that connects to my Galaxy phones, but really it’s just a heck of a display.

    The built in controls to set up the various functions was Great.
    The ability to set up the remote access the varying degrees of colors and sounds are nice.
    My family is amazed and in wonderment as to this
    The details are unbelievable
    I have folks who have asked where I purchased the TV.

    [This review was collected as part of a promotion.] Debated between this and the new LG oled tv. I could not be happier with my decision. We have a very bright room and this tv lights up in any condition of the room. Great picture, easy to use, looks great with the new PS5. 10/10

    [This review was collected as part of a promotion.] After approximately 100 hours of use, here are my current thoughts regarding this product;
    1. Picture Quality
    The picture quality of this product incredible. Whether it be streaming movies or playing video games, the quality is the best I have ever seen
    . Being a long time video gamer, I have watched the development of graphics and CGI develop over time. This television has unlocked the greater image quality that I have ever seen. The picture quality and brightness of this product is easily the most standout feature.
    2. Smart Features
    I have no complaints in regard to the content provided among the smart features. I have been able to access every streaming service I use with ease. From the start, I found the organization of these features to be relatively easy to work with and well formatted.
    3. Design
    This product is beautifully crafted. I was very surprised by how light the television was despite its very large size. The sleek finish and low profile fit great in any modern home. I was also very pleased with the heavy duty stand that came with the television. I feel that it provides a nice design with maximum security to prevent the television from falling forward or backward.
    4. My experience with this product
    From day one, I have been playing PlayStation 5 video games on this television. The picture quality is breathtaking, especially when combined with the latest generation of video game consoles. I am also a huge Star Wars fan and frequently re watch the series on a variety of platforms. After watching Star Wars: A New Hope (1977), I was shocked at the picture quality I was getting from a movie that is 44 years old.
    Overall, I am very grateful for this opportunity and am still amazed at how beautiful this product is, both in design and functionality. Without a doubt, the best television I have ever used or owned.

    i was very excited about this tv. i am 100% in the samsung ecosphere, samsung phones, 2 frame tvs and i love the ease of the samsung setup, and how my phones interact with the tv.
    this tv when running is ok. it’s incredibly harsh with bloom on almost any setting, but that isn’t the biggest issue. the biggest issue is that the tv appears like a giant prism in my living room during the day while running dark scenes. you can tell by the reflections the panel is distorted is some way and there is a large light wavy distortion running diagonally across the screen. i have never seen a panel this bad.
    i’d give this panel 0 stars if i could. i have been really happy with my frame tvs, so i will probably downgrade to the 65″ frame.

    [This review was collected as part of a promotion.] This TV has one of the viewing and sound experiences. The images are bright and crisp, while the sound is impacting. There is no need for a sound bar in my opinion. My family and I love watching 4K movies on it and playing on our PS5. There isn’t any lag and all the apps run smoothly.

    i previously owned the un55js8500 and the it is worth the upgrade to the newest qled tv. it took a few hours of my eyes to adjust to the picture quality and the brightness and how clear this tv performs. i’m really happy i made the purchase and it is going to be a good summer chilling in the air conditioned room. gaming on this tv are amazing, everything came in details which the old “js” model could not compare.
    if your cable box has no sound, try the hdmi (earc) port.

    i’m looking at getting my 3rd replacement tv because of panel defects such as stuck pixels and vertical banding. samsung’s only response so far is return, wait 2-3 weeks for a refund, order again, repeat. i would love to rate this tv higher, because with the exception of only having one hdmi 2.1 port, it checks all of the right boxes for my use case and is a decent step up from my old q8fn. however, i can’t recommend this tv knowing others might have to go through the same amount of hassle that i have gone through so far trying to get an acceptable unit.

    pockets for inserting power cable, usb, hdmi etc are shallow making it difficult to insert stiff cabled plugs in to sockets. the port labels are indented in black – difficult to read. tthe power cable socket gets coverd with mounting bracket and is at blind spot to insert power cable. very bad arrangements.
