Our take on the Samsung QN77S90D 4K Ultra HDR Smart OLED Tizen TV (2024)
The Samsung S90D is a 77-inch 4K OLED TV using QD-OLED panel technology, which combines OLED's per-pixel contrast with quantum dots for brighter, more saturated color than older OLED panels. It runs Tizen with the full Samsung app and gaming hub, and it has four HDMI 2.1 ports at 4K 144Hz for consoles and PCs. It suits movie and sports viewers who want deep blacks in a bright room and gamers who want high refresh without a separate monitor. Against the LG C-series it is generally brighter in color and similar in black level, while the LG adds Dolby Vision, which the S90D lacks.
- QD-OLED panel gives strong color brightness and near-perfect blacks
- Four HDMI 2.1 ports, all supporting 4K 144Hz
- Slim design with very thin bezels
- Tizen is fast and carries the major streaming apps and gaming hub
- Anti-glare coating handles daylight viewing well

Questions and answers
- Is the S90D better than the LG C4?
- The S90D is generally brighter in color and has four full 144Hz HDMI 2.1 ports. The C4 adds Dolby Vision, which the S90D lacks. Choose by whether Dolby Vision or extra color brightness matters more to you.
- Does the S90D support Dolby Vision?
- No. It supports HDR10, HLG and HDR10+, but not Dolby Vision. Dolby Vision content plays as HDR10.
- Is 77 inches too big for a normal living room?
- At 77 inches it suits viewing distances of roughly 8 to 10 feet for mixed TV and movies. Closer seating makes the picture more immersive but can reveal lower-resolution sources.
- Can it run games at 4K 120Hz or 144Hz?
- Yes. All four HDMI ports are HDMI 2.1 and support 4K at up to 144Hz, with VRR and ALLM for consoles and PCs.
- Do I need a soundbar with it?
- Most reviewers recommend one. The built-in speakers handle everyday TV but lack bass and scale for movies.
- Is OLED burn-in a real risk?
- It is lower than on early OLEDs but still possible with constant static logos or tickers. The TV dims static elements automatically, and varied content reduces the risk.
