Is the Samsung MU6070 a good TV for a living room?

Yes for everyday streaming and cable in a bright room. Its 65-inch 4K panel is the main draw, but dark-room contrast and wide-angle viewing are weaker than on step-up models.

It accepts HDR signals, but the panel can't produce the brightness or color range of better HDR sets. Expect a modest improvement, not a dramatic one.

What is the refresh rate?

The panel is 60Hz. That is fine for most shows and movies, but fast sports and games can show motion blur.

What inputs does it have?

It has three HDMI inputs, plus USB and an antenna/cable connection. That covers a cable box, a console and a streaming stick with one port to spare.

How does it compare with newer Samsung 4K TVs?

Newer models add better HDR, improved backlights and updated smart features. The MU6070 remains a basic 4K set, so choose it for the screen size rather than for advanced picture technology.
