Samsung M80H Mini LED 4K TV vs Roku Plus Series 55" QLED Mini-LED TV

The Samsung M80H is the better pick for gamers and for anyone who wants a bright, punchy Mini-LED picture with a 144 Hz panel and three HDMI inputs. The Roku Plus Series is the easier TV to live with: QLED color, Dolby Vision and Dolby Atmos, four HDMI ports and the simplest smart interface on the market. Both are rated 4.7 out of 5 by owners, so the choice comes down to motion and brightness versus format support and ease of use.

  • Choose the Samsung M80H if you play console or PC games and want 144 Hz motion, Samsung's AI upscaling of older SDR content, and Tizen with its free channels and game hub.
  • Choose the Roku Plus Series if you want Dolby Vision and Dolby Atmos support, four HDMI ports, and the Roku home screen that anyone in the house can pick up in minutes.

Questions and answers

Which is better for gaming, the Samsung M80H or the Roku Plus Series?
The Samsung M80H. Its 144 Hz panel and low latency mode handle 120 fps console output, while the Roku Plus Series tops out at 60 Hz. The Roku still plays games fine, but fast shooters and racing games look smoother on the Samsung.
Does the Roku Plus Series have Dolby Vision that the Samsung lacks?
Yes. The Roku supports Dolby Vision, HDR10+ and HLG, and adds Dolby Atmos audio. The Samsung supports HDR10+ and HLG but not Dolby Vision, so Dolby Vision movies play in standard HDR10 on it.
Which TV is brighter?
Both use Mini-LED backlights and reach similar peak brightness in the 55-inch class. The Samsung's processor pushes highlights harder in bright rooms, while the Roku favors more accurate color in darker rooms with Dolby Vision content.
Is the Samsung worth stepping up to over the Roku?
Step up to the Samsung if you game or watch a lot of sports and want the 144 Hz motion. Stay with the Roku if you mainly stream movies and want Dolby Vision, Dolby Atmos and four HDMI ports.
Which has the easier smart interface?
Roku OS is simpler. The home screen is a plain grid of apps and the voice remote works hands-free. Tizen has more built-in content and gaming features but more menus to learn.
Do either of these need a soundbar?
Both have 2-channel speakers around 20 W, so a soundbar improves either one. The Roku is the better base for one because it has eARC and Dolby Atmos passthrough.
