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!

GREAT ON SALE
I’ve had the Samsung S90F for about a week now, and it’s easily the best TV I’ve ever owned. The OLED panel is incredible, delivering perfect blacks and amazing contrast that make movies and games look stunning, especially in a dark room. At the same time, it’s surprisingly bright, so colors still pop and the picture stays vibrant even in a fully sunlit room during the day. I paired it with a Samsung soundbar and subwoofer, which definitely enhance the experience, but I was genuinely impressed by the TV’s built-in speakers. They’re clear, full, and more than capable for everyday viewing if you don’t have a separate audio system. Overall, the S90F has exceeded my expectations. Whether you’re watching movies, gaming, or streaming sports, the picture quality is outstanding and the TV performs exceptionally well in both bright and dark environments. I couldn’t be happier with the purchase.

For gaming and moderate to low light rooms, it's unbeatable
I was waiting for this 65-in model to go on sale, I missed the spectacular 4th of July pricing but then it dropped down to a reasonable price and I pulled the trigger. I primarily use this set for gaming, coming from the LG OLED lines, I can clearly confirm the color on the Samsung qd LEDs are spectacular. I burned in the set for 26 hours and it performed flawlessly. My motto also had no issues with panel quality or dirty screen. For gaming it has been terrific, they have a game bar configuration packed full of customization options. The glare off the set is also manageable, since I game in a low light room and I can control the light,. So far it's a high recommendation

Great picture.
Excellent tv. I don't put the tv on pause but apparently OLED tv's can suffer if held on the same frame for too long. To me, the biggest difference I've learned about between OLED and QLED is that OLED tv's can suffer if paused for too long while QLED is almost immune to this problem. I love this tv and that info is from AI not my actual experience. But, I do not pause this OLED tv. If you do stop it, it will throw up a screen saver/ floating image.

Liquid blacks, nice remote. Love this tv.
Great picture. I was concerned that qd-oled might reveal brownish blacks when compared to w-oled, but it doesn't appear to be any different than the LG C4 it replaced. It looks brighter to me but my LG is older now, so check the specs. It's very bright in standard mode though. I will never accept a matte screen again, but reflections are obvious in brighter rooms with darker content. Project Hail Mary might benefit from curtains. Tizen interface operates almost identically to the LG C4 WebOS which I despise. The settings menus are simpler and it doesn't have the gimmicky inertial mouse nonsense, so it's better in those respects. (Roku killed it with theirs and no other OS/remote combo will ever make me happy.) The solar/rechargeable remote is great. I did like having the number buttons on the clunky cheap feeling remote from LG, but the rapid scroll features on tizen make this a non-issue. I cannot imagine what more you could get for double the money. Just a gorgeous picture. Love it.

Beware of buying very fragile expensive items.
I had a very disturbing experience with this purchase. I bought our our Samsung 48” OLED S90F from Amazon. I never saw this tv on a showroom floor so I was very surprised by what I found. When it was delivered no damage was apparent. However I did notice the packing tape used was clear plastic, not paper tape. Once out of the box I noticed the glass panel ended abruptly and without any protective bezel. Just a vulnerable glass edge. “Odd”, I thought. I continued to set up the tv and plugged it in. Nothing happened. I checked the remote. Nothing. After checking everything again I contacted Samsung via their website. I used Chat to walk me through troubleshooting. Sales expert Camille took my info and sent a checklist of possible solutions. Item #3 said, “Test the Screen. Shine a flashlight on the screen while the TV is on. If you see faint images, the backlight may be faulty though with OLED, it could be a panel issue.” I assumed the tv was on so I did as instructed. Guess what? I discovered a faint “star” crack at the left mid center edge of the panel. Then I noticed a very faint crack leaving that star and trailing all the way to the mid center top! I had my daughter corroborate my find. Believe me, we were uber gentle unpacking this tv and placing it on a cushioned ottoman. I messaged Camille back with our find and she responded, “ Thank you for sharing that. Operator message sent at 10:07 PM: Thank you for your patience. While we, as the Pre-Sales Team, primarily handle product orders, I tried to find a resolution for you. Unfortunately, our expertise and tools are limited for this specific concern. No worries! I can assist you in connecting with the appropriate department for your technical inquiry.…..” but not until Monday! This was Friday. Next day, I decided to check Best Buy for the same tv and for only $2 more, they had one left in the whole tri state area. I bought their last one. The box had original paper packing tape sealing the box. The glass panel had a thin but visible bezel all the way around the tv’s glass edge! What’s more, the panel had a thin clear plastic protector covering the tv’s face! I looked at the Amazon tv and sure enough there wasn’t one of those! And there were faint scuff marks across the panel too! There’s no doubt in my mind this was a previously returned and repackaged $1614.83 tv. I do thank Amazon, thank you Jeff, thank you Prime, for refunding my money after a nail-biting few weeks of investigation into my claim. Very disappointing, very disturbing. Beware of buying very fragile expensive items.

Amazing Mid Range TV- Sound Quality, picture quality, great tv size
55 in OLED tv is about as big as I can go for my apartment and this OLED and it was super easy to set up. Could use the smart things app as a remote and set the whole tv up. Kinda heavy for one person to pick up so make sure there is two people to assemble safely.

Great smart TV, using in living room
I now have 2 Samsung TV's and I'm very pleased with both. This particular set has excellent color and sound. Ultra thin and for me, easy to set up based on already having a Samsung account. Amazon was late with the delivery otherwise it would have had 5 stars.
