This is a great TV. Awesome picture sharpness and brightness. However, the sound is unpredictable. There is an option to auto adjust the sound, but you can't figure out how it works. Sometimes the sound is too low, so you turn it up, but a next minute it jumps to loud. Next minute it's too low. There is no rhyme or reason. So I turned it off but again you never know if you need to turn it down to 10 or up to 50. I love how thin it is with a small stand. You could easily put it in your fireplace mantle without needing a bracket.

[This review was collected as part of a promotion.] This is a fantastic TV! It installed and started up immediately, meshed perfectly with my other products and the updates installed seamlessly. The picture quality is outstanding, so glad I didn't choose a cheaper unit. The sound is great, I will be installing a Sonos bar next. We will definitely purchase more of this class, I hope it comes in 100" for the next room. The TV is amazingly thin, it looks like a floating sheet of glass on the wall.

The UI is horrific. Clunky and slow, but worst of all, the TV automatically turns itself on activates its "music wall" when you walk by with a phone or when a Bluetooth device within range broadcasts a pairing request, which some cheap Bluetooth transmitters do, without an option to shut them off. Even a nearby neighbor's device could trigger it. Google it, you'll find lots of complaints about this, which Samsung considers a "feature" and which cannot be deactivated. Good picture quality, which is why I give it 2 stars But I'm probably going to return it. I can't have Samsung deciding when my TV will turn by itself.

The picture quality is great. Also, being able to add Bluetooth earbuds while leaving on the main sound is a nice touch since I am hard of hearing. The only issue that drives me crazy is that the HDMI port is not defaulting to my FireStick HDMI (1) port. Keeps going to HDMI 3. Tries several solutions with no luck. I also wish there was one document that discussed all the setting you can set. Flipping through multiple web sites is a pain with many times not getting a clear understanding of the setting. Overall is a nice upgrade.

AI makes it easy if you don't want to adjust anything out of the box, but it gets in the way when you want to make manual changes. So, instead of feeling better for upgrading from a 17-year-old non-smart TV to an AI-powered OLED, I feel like I have entered a Greek tragedy where a mortal fights against the Fates. Since I don't have the hubris of Odysseus, I am content to accept what Samsung has decided I need and leave setting AI optimized. The positive part is that I got exactly what I saw in the store, but the weakness is that if you don't like it at home, you may have to take it back to the store.

[This review was collected as part of a promotion.] Honestly, I've been through a ridiculous number of TVs over the years—flagship LEDs, fancy QLEDs, you name it—and the 77-inch Samsung OLED is hands down the best one I've ever owned. The contrast is insane: blacks are truly black, highlights pop, and everything just looks three-dimensional. The uniformity is perfect too—no weird blotches, no banding, no dirty screen effect, just a clean picture from edge to edge. And the brightness? It's bright. Like, actually bright, even in a room with windows, and it still keeps that punchy, vibrant look. The upscaling is crazy good as well—older 1080p stuff and even 720p looks sharp and detailed, almost like 4K, without that noisy, artificial look. Game Mode is where it really shocked me: the responsiveness is nuts, input lag is basically nonexistent, and fast shooters feel so smooth and immediate that it genuinely gives you an edge. If you're on the fence, just get it—this is the one.

I like the larger size tv I am about twelve feet away from tv. Picture quality is very good. Setting up to WiFi was easy and setting up streaming services was also very easy. After learning the Remote control it is easy especially with speaker button

[This review was collected as part of a promotion.] The picture is amazing. This tv sits adjacent to a window and there is never a glare. The brightness, infinite contrast, and absolute black gives top notch 4k quality. The Samsung Hub is very responsive and the uniformity across Samsung makes usability intuitive.

[This review was collected as part of a promotion.] Picture is pretty good but getting “preparing try again later” when I'm just trying to set a sleep timer or change screen brightness is super annoying since it happens every time. Not gonna lie I likely won't ever buy another or recommend it

Simply amazed at the picture! Was concerned about reflection while off and on, those concerns vanished once the set was installed. Looks very classy on the wall, and while reflections when off are visible, this is not an issue, happy I did not go with the non-reflective screen the S90H has. Very happy with purchase!
