Our take on the Samsung QN77S90F 77-inch

The Samsung S90F is a 77-inch 4K OLED TV with a 120Hz panel that reaches 144Hz for PC gaming, run by Samsung's NQ4 AI Gen3 processor. It uses QD-OLED, which gives it strong color brightness and wide viewing angles, and it carries four HDMI inputs, Tizen with built-in streaming apps, and a 2.1-channel 40W speaker system. It suits movie watchers and console or PC gamers who want deep blacks in a bright room. Against the LG C-series it trades a little peak brightness in small highlights for punchier color, and it lacks the anti-glare coating and four full-bandwidth HDMI 2.1 ports of the step-up S95F.

Best forMovie and streaming fans in a bright living roomConsole and PC gamers wanting 144HzBuyers who want a big OLED without the top-tier priceWide seating layouts
Pros
  • QD-OLED panel gives deep blacks and vivid, bright color
  • 120Hz native, up to 144Hz for PC input
  • Four HDMI inputs, enough for a console, soundbar and streaming box
  • Tizen is fast and has all major apps built in
  • Slim design with a near-borderless picture
Cons
  • Only 40W of built-in sound; a soundbar is worth adding
  • No anti-glare coating like the S95F, so reflections show in bright rooms
  • Not all four HDMI ports are full-bandwidth HDMI 2.1
  • OLED panels can dim static logos and scoreboards over time
  • Stand is basic and the set needs a wide, sturdy surface

Questions and answers

Is the S90F good for gaming?
Yes. It has a 120Hz panel that reaches 144Hz on PC, low input lag and four HDMI inputs. Check which ports carry full HDMI 2.1 bandwidth for 4K at high frame rates.
How does it compare with the Samsung S95F?
The S95F is brighter and has an anti-glare coating and more full-bandwidth HDMI 2.1 ports. The S90F keeps the QD-OLED picture for less.
Do I need a soundbar?
Most owners say yes. The 2.1-channel 40W system is fine for news but thin for movies, so a soundbar or AV receiver improves it noticeably.
Is 77 inches too big for my room?
For a typical sofa distance of 8 to 10 feet, 77 inches fills the view without feeling overwhelming. Measure the wall and stand footprint first; the set is wide and needs a sturdy surface.
Does it support Dolby Vision?
No. Samsung TVs use HDR10+ and do not support Dolby Vision, so Dolby Vision content plays in HDR10 instead.
What is in the box?
The TV, its stand, the SolarCell remote, a power cable and paperwork. HDMI cables and a wall mount are not included.
