The Samsung 77-Inch Class OLED S90F 4K Smart TV is down to $2,099.99 from $3,499.99, so you are looking at a $1,400 drop on a very large OLED screen. If you have been thinking about turning your living room into more of a home theater, this is the kind of size and panel type you usually see priced a lot higher. At 77 inches, you are getting a massive picture with 4K resolution (3,840 x 2,160), so movies, sports, and games will look sharp even if you sit a bit closer than you would with a smaller TV. Since it is OLED, each pixel can turn on and off on its own, which gives you the deep blacks and strong contrast people like for dark movies and night scenes.
The S90F uses Samsung’s NQ4 AI Gen3 Processor with 4K AI Upscaling Pro, which helps clean up lower-resolution content. So if you watch older shows, cable channels, or streaming that is not native 4K, the TV works to make it look closer to true 4K instead of soft and blurry on a big 77-inch screen. OLED HDR+ is there to boost bright highlights and detail in both bright and dark parts of the picture, so you can see texture in shadows without washing out the bright areas. The anti-reflection layer also helps if you have windows or lamps in the room, so you are not staring at your own reflection every time the screen goes dark.
If you game, the Motion Xcelerator 144Hz support is one of the stronger reasons to pick this model. You get a 120Hz panel that can go up to 144Hz, which is great if you game on a PC that can push high frame rates, or want smoother motion on next‑gen consoles with high refresh support. Fast sports and action scenes will look smoother with less blur, and input lag is lower than on basic 60Hz sets. That means better control response in shooters, racing games, and anything where timing matters. On a 77-inch screen, that can make the whole setup feel closer to a big gaming display than a basic living room TV.
As a smart TV, the S90F has Samsung’s smart platform plus Alexa built in, so you can use voice to change channels, open apps, or search for stuff to watch without hunting through menus every time. Samsung Vision AI adds more smart features, like better content recognition and smarter settings, which can help you get a better picture without spending a ton of time in menus. With all of that tied into a huge 77-inch OLED panel and a $1,400 discount, this deal makes sense if you want a big upgrade you will keep for years instead of buying another mid-range TV that you will want to replace again soon.
