Review: As Always, Samsung TVs Are Top Notch! - Holy smokes, this TV looks FANTASTIC! Our 55" Samsung that was 12 or so years old finally bit the dust by way of the HDMI connection constantly blinking out. So, I sprung for the 77" that we've been wanting for awhile. The colors are brilliant and very sharp, while the 120Hz refresh rate for 4K makes viewing easier on the eyes than a slower refresh rate. There is overwhelming evidence that going from 60Hz to 120Hz reduces eye strain, headaches, fatigue and the likes. I've also been reading that going all the way up to a 240Hz refresh rate yields diminishing returns, unless you're into prolonged stretches of intense gaming on that TV/Monitor. Since we don't use this TV for long, intense gaming sessions, I decided not to go with a 240Hz model. I'm very pleased with everything about this TV. There is absolutely nothing that I can complain about. There are plenty of HDMI ports available, and the remote control is simple and easy to navigate. Also, the Samsung TV menu navigation has been greatly improved from our old Samsung. I am very pleased with this. Also, there are dozens (perhaps hundreds?!) of FREE channels that Samsung has built into their TV menu. While navigating these free Samsung channels, I suddenly discovered that I had watched a full episode of a show I hadn't seen in years. Although I utilize a separate amp and 7.2 sound, I will say that the built-in speakers are decent quality. I would have no problem using these built-in speakers, if it were all I had. The sound is not tinny, nor obviously under-powered, as so many other large TVs are. The built-in speakers are not bad at all. Also worth mentioning is that this TV is very thin, but also very rigid and stiff, relieving my worries that it would accidentally twist during wall-installation, causing irreparable damage. Quite on the contrary--this TV is tough! I had no issues whatsoever, lifting it with one other person of small stature, and hanging it onto the wall-mount. I never once felt like it was going to flex or twist itself into oblivion. I have no fears when needing to pull it away from the wall and service the wiring or anything behind the TV. I will recommend this line of Samsung TVs to anyone who asks. As always, Samsung is a top-notch choice for TVs!

### ⭐⭐⭐⭐⭐ Almost Perfect
*by A***. on March 5, 2026*

As a quantum dot OLED, not many TVs beat this in terms of color and deep blacks. Just know that it isn’t designed for extremely bright rooms and will be unable to create perfect blacks in one. Samsung’s Q-Symphony lets you sync the TV speakers with a Samsung soundbar, which sounds impressive. It’s a big upgrade from my QLED TV, which didn’t offer this. If you like minimalist remotes, this one is perfect. It has a textured surface on the back to help you grip it and it feels sturdy. The main cons are that the design isn’t ideal and the anti-reflective coating comes off easily. The mounting holes are low given its bottom-heavy design and the screen seems fragile on the top and sides where it’s thinnest. Not a big issue if you plan accordingly. The other more serious con is it’s extremely easy to permanently remove the anti-reflective coating on the screen if you don’t clean it carefully. Merely rubbing too hard with water can damage it, so be careful. Despite these flaws, it’s still a truly phenomenal TV, especially at current prices.
