Which is better for gaming, the M7 or the U7?

The U7. Its 165Hz panel, VRR from 48Hz to 165Hz, HDMI 2.1 and Game Booster 330 cut lag and keep fast motion smooth. The M7 tops out at 60Hz.

Is the U7 worth about $223 more than the M7?

Yes for sports, gaming or a bright room. The U7 gives 3000 nits against 1000, 165Hz against 60Hz, and 50W Devialet-tuned sound. If you mostly watch movies at night, the M7 covers the basics for less.

Which has better sound without a soundbar?

The U7. It has a 50W 2.1.2 system with a built-in subwoofer tuned by Devialet. The M7 has 10W x 2 plus a 20W subwoofer with Dolby Atmos, which is adequate but smaller.

Which is brighter in a sunny room?

The U7, at up to 3000 nits versus 1000 nits on the M7. The U7 also has up to 3000 local dimming zones, which helps contrast when light hits the screen.

Do both run Google TV?

Yes. Both use Google TV with voice control. The U7 adds Gemini AI for content discovery; the M7 uses Google Assistant.

Neither maker publishes a lifespan figure, so there is no clear winner. Both are 2026 models with the same 4K resolution. The U7's HDMI 2.1 ports are more future-proof for newer consoles.
