Our verdict
Samsung gives the M80H a 65-inch screen, built-in streaming apps and support for games at up to 144Hz, meaning the screen can update up to 144 times a second with compatible equipment. Those features help only if the picture keeps up. Samsung calls it a Mini LED TV, a type that uses many small backlight LEDs, but RTINGS found its 65-inch US test unit had no local dimming, the feature that dims parts of the backlight for darker blacks. RTINGS also found blurry motion, weak dark-scene contrast and distracting reflections, though input lag was low. We have not tested the UK UE65M80HAUXXU, so this is a cautious buying assessment rather than a claim of identical UK measurements.
Buy it if
- You want Samsung's menus and connections and can compare the picture in a shop first
- Your room has moderate, controlled light and you mainly watch ordinary programmes
- The exact 65-inch UK model is priced convincingly below a better-tested alternative
Skip it if
- You expect 144Hz to guarantee crisp movement in fast games
- You watch a lot of dark films or TV beside bright windows
- A cheaper rival gives a visibly better picture at the same screen size
How it would fit your home
Playing a fast game
The 144Hz figure tells you which signals the TV can accept from compatible equipment. It does not tell you how clearly a moving player or car appears. RTINGS found obvious blur on its 65-inch US test unit despite low input lag and gaming options.
Watching films at night
Samsung calls this a Mini LED TV. RTINGS found no local dimming on its tested variant, and dark scenes looked washed out. If film nights matter most, compare an OLED or a TV with proven local dimming.
Putting it in the family room
The built-in apps let you start watching without another box. Check the exact UK catch-up apps you need, where your lamps and windows are, and how the picture looks from the seats your family uses.
The details, in plain English
The gaming number needs context
A 144Hz refresh rate means the screen can show up to 144 frames a second. It helps only when a console or PC, the game and the connection all send a matching signal; a PS5 or Xbox Series X tops out at 120Hz. RTINGS measured low input lag, the delay between pressing a button and seeing the result, but the tested screen still smeared fast movement. Judge moving game footage, not just the 144Hz badge.
Contrast and dark scenes
Mini LED TVs use many small LEDs behind the screen. Better models add local dimming, which darkens the backlight behind dark parts of the picture, so blacks look deeper. RTINGS found no local dimming on its 65-inch US test unit, and dark scenes looked washed out. It also found reflections from lamps and windows distracting. Regional versions can differ, but do not assume the Mini LED label brings OLED-like blacks.
What to compare at checkout
Samsung UK listed the exact 65-inch model at £849 on 20 September 2026. The Amazon buying route is still a search, not a verified exact-model offer. Confirm UE65M80HAUXXU, the seller, the current delivered total and whether a rival at the same price offers a better picture in moving sport and dark film scenes.
Strengths and drawbacks
What it does well
- A 65-inch screen gives films and games plenty of space
- Samsung lists up to 144Hz and gaming features for compatible consoles and PCs
- RTINGS measured low input lag on its US test unit, so controls feel responsive
- Built-in apps and several inputs can simplify a family setup
What to watch out for
- RTINGS's test of the US variant found fast games and sport visibly blurry
- No local dimming on the tested variant: dark scenes lacked the contrast the Mini LED label may suggest
- Bright windows or lamps opposite the screen can remain distracting
Compare a real moving sport or game scene and a dark film scene with another 65-inch TV at the same current price. Features alone are not a reason to pay more.

Solves: bright windows or lamps opposite the screen can remain distracting
SANUS VLF728-B2, full-motion mount for 42–90-inch TVs Not yet reviewed by us
Changing the screen angle may move a visible window or lamp reflection out of the main seat’s view; it cannot improve brightness or panel contrast.
Check first: No fit claim until exact TV weight, VESA hole spacing and wall structure are confirmed. Qualified installation may add cost; cannot improve the TV’s intrinsic off-angle picture.

Where our findings come from
Research-based assessment, updated 20 September 2026. Samsung's UK page establishes the UK model and advertised features; RTINGS bought and tested a 65-inch US variant. We have not measured the UK unit and regional differences are possible. We have excluded this TV from automatic recommendations until its UK picture performance is better verified.
