Our verdict
The Samsung S90H is an OLED TV: each pixel makes its own light and can switch fully off, so dark scenes look properly black and colours stand out. Its Glare-Free screen stops windows and lamps showing up as mirror-like reflections, which is the main reason to choose it for a bright living room. It also has stronger speakers than its cheaper sibling, the S85H (40W 2.1-channel against 20W 2.0-channel), plus four HDMI 2.1 ports and a 165Hz refresh rate for smooth gaming. Tom's Guide found the S85H's picture surprisingly close in ordinary viewing; the S90H pulls ahead in very bright scenes, in sunny rooms and on sound. At our 24 September check the 65-inch S90H was £70 cheaper than the 65-inch S85H, which makes it the better buy at those prices. The gap changes, so compare both exact models before you buy.
Buy it if
- Reflections from windows or lamps make your current TV hard to watch
- You want better sound than a typical thin TV without buying a soundbar straight away
- You play on a PS5, Xbox Series X or gaming PC and want smooth, responsive games
Skip it if
- The S85H is much cheaper on the day you buy
- You mostly watch in a dark room, where the Glare-Free screen matters less
- You need Dolby Vision support
How it would fit your home
A sunny living room
The Glare-Free screen is the feature most likely to make everyday viewing more comfortable when you cannot draw the curtains.
Watching without a soundbar
The 40W 2.1-channel speakers are clearer and fuller than most thin TVs, with twice the power of the S85H's 20W.
Buying for value
Compare the exact 65-inch prices first. The S90H's reflection control and sound are easiest to justify when the gap to the S85H is small.
The details, in plain English
Picture quality
On an OLED screen each pixel lights itself and can switch fully off, so night scenes look properly dark while bright details stay crisp. Tom's Guide measured about 1,500 nits of HDR brightness on the 55-inch model in Filmmaker Mode, enough to give sunlight, explosions and stadium lights real punch. In their side-by-side test the S85H looked close much of the time; the S90H's extra brightness showed most in very bright scenes and in making shadow detail easier to see. Filmmaker Mode gives the most accurate picture, but it can look a little dim in the darkest programmes, so try the brighter film setting if you need to.
Watching during the day
Samsung's Glare-Free screen is designed to stop windows and lamps appearing as sharp, mirror-like reflections. In a moderately lit room you may barely notice it. In a room with a big window you cannot cover, it is the feature most likely to change how comfortable the TV is to watch, and the main practical reason to choose the S90H over the S85H.
HDR formats and picture settings
HDR (high dynamic range) lets bright and dark parts of a scene keep their detail at the same time. The S90H supports HDR10+, HDR10 and HLG, the format used for some live broadcasts, but not Dolby Vision. Films mastered in Dolby Vision still play in HDR, just not that version of it. At first setup Samsung turns on an automatic picture enhancement. Tom's Guide found it often made the picture too bright and slightly blue, so switch to Filmmaker Mode or Movie mode for a more natural look.
Sound
Most thin TVs have small, weak speakers. The S90H has a 40W 2.1-channel system (the ".1" is a dedicated bass speaker) with Dolby Atmos, against 20W and 2.0 channels on the S85H. Tom's Guide found it had enough punch for a respectable experience, so you can put off buying a soundbar. When you do add one, the eARC HDMI port sends full-quality sound to it, and Q-Symphony lets a compatible Samsung soundbar play alongside the TV's own speakers.
Gaming
The screen can refresh up to 165 times a second (165Hz). A PS5 or Xbox Series X runs games at up to 120Hz, so consoles get their smoothest mode, and a gaming PC can go further. All four HDMI ports are HDMI 2.1, so you do not have to choose which console gets the best socket. Tom's Guide measured 9.3 milliseconds of input lag in Filmmaker Mode, meaning the delay between pressing a button and seeing the result is too short to notice. Variable refresh rate (VRR), with AMD FreeSync Premium Pro and NVIDIA G-Sync, stops the picture tearing when a game's frame rate dips.
Strengths and drawbacks
What it does well
- OLED picture: deep blacks, rich colour and fine detail in films
- Glare-Free screen stops windows and lamps reflecting like a mirror
- 40W 2.1-channel speakers with Dolby Atmos: fuller sound than most thin TVs
- Four HDMI 2.1 ports and up to 165Hz: smooth, responsive gaming on every input
- A very slim screen that looks discreet on a wall or stand
What to watch out for
- The cheaper S85H looks very similar in everyday viewing, especially on offer
- No Dolby Vision: films in that format play in HDR10+ or standard HDR instead
- The automatic picture mode Samsung turns on at setup can look too bright and blue
- The very thin screen needs careful handling during setup
The S95H is Samsung's brighter flagship. The S85H gives you much of the same OLED picture for less when it is discounted, but with weaker 20W speakers. The S90H makes most sense when its Glare-Free screen and stronger sound solve a real problem in your room, and the price gap to the S85H is small or in the S90H's favour.
