Samsung M70HB Mini LED 4K TV vs Roku Plus Series 55" QLED Mini-LED TV

The Samsung M70HB is the bigger, brighter set: 65 inches of Mini LED with strong dimming, a 120Hz-class motion rate and Samsung's Gaming Hub, backed by a large base of owner ratings. The Roku Plus Series is the better value in picture quality per inch of screen: QLED with Mini-LED backlight and Dolby Vision, plus Dolby Atmos and a hands-free voice remote, in a smaller 55-inch size. Pick Samsung for a large, bright living-room TV with gaming features; pick Roku for a simpler, film-friendly set with better HDR format support.

  • Choose the Samsung M70HB if you want a 65-inch Mini LED set for a bright room, gaming and a big built-in free channel lineup.
  • Choose the Roku Plus Series if you want Dolby Vision and Dolby Atmos with the simplest smart TV interface in a 55-inch size.

Questions and answers

Which is better for gaming?
The Samsung. It has Motion Xcelerator with DLG 120Hz and Samsung Gaming Hub, while the Roku is a 60Hz set. For a console at 60 frames per second the Roku is fine, but fast games look smoother on the Samsung.
Which has the better picture?
The Roku supports Dolby Vision and HDR10+, which helps with film and streaming content mastered in those formats. The Samsung's Mini LED dimming and larger screen give it more punch in a bright room. It depends on whether you value format support or size and brightness.
Is the Samsung worth stepping up to over the Roku?
Step up if you want a 65-inch screen, 120Hz-class motion and gaming features. Stay with the Roku if Dolby Vision, Dolby Atmos and a simpler interface matter more and 55 inches fits your room.
Which is easier to use?
The Roku. Roku OS is one of the simplest TV interfaces, and the enhanced voice remote works hands-free. Tizen is also well organized but has more layers and settings to learn.
Do either support a soundbar?
The Roku has eARC, so it passes high-quality audio to a soundbar cleanly. The Samsung has HDMI and Bluetooth for soundbars and speakers but no eARC listed.
Which lasts longer?
Neither maker publishes a lifespan figure. Both are LED-backlit sets with similar panel life. The Roku's higher owner rating comes from far fewer reviews, so treat it as a weaker signal than the Samsung's larger sample.
