Our take on the Samsung UE55M70H

The Samsung UE55M70H is a 55-inch 4K Smart TV with a Mini LED backlight and Samsung's Mini LED Processor 4K. It targets everyday film, series and broadcast viewing, with HDR support and upscaling of lower-resolution sources. Against standard LED 4K sets it offers finer backlight control and better contrast, though it sits below Samsung's Neo QLED lines in peak brightness and local dimming. It is a sensible pick for a bright living room where a mid-range Mini LED set is enough.

Questions and answers

Is the Samsung UE55M70H worth it over a standard LED 4K TV?

If you want deeper blacks and better contrast for films and series, the Mini LED backlight is a real step up from edge-lit LED sets. If you mostly watch bright daytime TV, a cheaper standard LED model may be enough.

How does it compare with Samsung Neo QLED TVs?

Neo QLED sets use more dimming zones and reach higher brightness, so they handle HDR highlights and dark scenes better. The UE55M70H is the more affordable Mini LED option and covers everyday viewing well.

What size is the screen and what resolution does it have?

It is a 55-inch (138 cm) screen with 4K UHD resolution of 3840 x 2160 pixels. That is four times the pixels of Full HD.

Does it upscale older HD broadcasts?

Yes. The Mini LED Processor 4K upscales lower-resolution sources, though results depend on the quality of the broadcast or stream and your connection.

What can I connect to it?

It has multiple connections for external devices such as consoles, players and set-top boxes, plus access to online entertainment apps through the Smart TV platform.

What is in the box?
