Which has the better picture, the QM6K or the QM7K?

The QM7K sits higher in TCL's lineup and adds Dolby Vision IQ, HDR10+ and an anti-glare screen. The QM6K is still a strong QD-Mini LED set, but expect the QM7K to handle bright rooms and HDR content better.

Is the QM7K worth the extra money?

At $599.00 at eBay versus $477.99 at Amazon as of November 7, 2026, the gap is about $121. It is worth it if you watch a lot of Dolby Vision content or have a bright room; otherwise the QM6K saves money.

Which is better for gaming?

The QM6K lists a 144 Hz native panel and Game Accelerator 288, while the QM7K lists 120 Hz. Both have four HDMI ports and auto game mode, so the QM6K has the edge on paper for high frame rates.

Which has better sound?

The QM6K lists an ONKYO 2.1 system with a subwoofer at 40W plus Dolby Atmos. The QM7K lists DTS:X but no subwoofer. A soundbar is still a good idea for either.

Do both run Google TV?

Yes. Both use Google TV and support Google Assistant and Alexa. The QM7K also lists Apple HomeKit.

Which sizes can I get?

The QM6K comes in 50, 55, 65, 75 and 85 inches. The QM7K comes in 55, 65, 75, 98 and 115 inches, so it is the only one of the two with very large sizes.
