## Customer Reviews

### ⭐⭐⭐⭐⭐ GREAT ON SALE
*by  on Reviewed in the United States July 10, 2026*

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.

### ⭐⭐⭐⭐⭐ Liquid blacks, nice remote. Love this tv.
*by  on Reviewed in the United States July 6, 2026*

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.

### ⭐⭐⭐⭐⭐ Samsung 4K QN65S90F Smart TV
*by  on Reviewed in the United States July 20, 2026*

I’m totally satisfied with my new Samsung QN65S90F. I investigated calibration settings and found that the TV was almost spot-on to my liking. To get the best results you must set both SDR and HDR separately when viewing each format.I was surprised by the “thinness” of the screen in relation to previous Samsung models I’ve owned. Handle with care when moving it around since the screen is not very rigid. There is a small bezel that is not visible when powered off. Everything is flush to the screen.I’ve been impressed by the video quality and flesh tones are very natural looking. The UHD picture really shines whether watching streaming apps or 4K BluRays.I’ve had the TV for five days and I’m delighted with this purchase. Arrived in two days, surprisingly. See photos from YouTube.
