Is Mini LED worth it over a regular LED TV?

Mini LED uses many smaller LEDs in more dimming zones, so dark scenes keep deeper blacks and bright highlights pop more than on edge-lit sets. The gap is visible in movies and HDR content, less so in bright daytime TV.

Does it really run at 120Hz for gaming?

The panel is 60Hz natively. Motion Xcelerator adds a 120Hz DLG mode, which doubles the refresh rate at reduced resolution, so it helps motion smoothness but is not a true 120Hz panel.

What is Wi-Fi 6E good for here?

Wi-Fi 6E adds the 6GHz band, which is less crowded than 2.4GHz and 5GHz. You need a compatible router or access point to benefit; otherwise the TV falls back to older Wi-Fi.

What sound features does it have?

It has Adaptive Sound, which adjusts audio to the content, and Object Tracking Sound Lite, which follows on-screen action with the speakers. It is an improvement over basic TV audio but no substitute for a soundbar.

How does it compare with Samsung's Neo QLED models?

Neo QLED sets have more dimming zones, higher brightness and true high refresh panels. The M70H gives you Mini LED contrast and the same smart platform at a lower tier, with fewer zones and a 60Hz native panel.
