Hisense M7 Mini-LED QLED 4K Google TV vs Hisense M7 Mini-LED 4K Google TV

Both are Hisense M7 Mini-LED Google TVs with the same platform and 60 Hz panel, so the real choice is size. The 55-inch 55M7SG is the better-documented set: 1,000 nits, QLED color, Dolby Vision IQ and Gaming, a 20 W subwoofer and Bluetooth 5.4, and it holds 4.4 out of 5 from about 1,400 ratings. The 65-inch M7 gives you a much larger picture for a big room, but it lists a full-array backlight rather than Mini-LED, two speakers with no stated subwoofer, and no published brightness or rating. Buy the 55-inch for a normal living room or a bright room where punch matters; buy the 65-inch only if screen size outweighs the extra picture and sound hardware.

• Choose the Hisense 55M7SG if you sit about 6 to 9 feet away and want the brighter, better-equipped Mini-LED set with a subwoofer and full Dolby Vision support.
• Choose the Hisense 65-inch M7 if your room is large enough that a 65-inch screen matters more than peak brightness and built-in bass.
