Is the TCL QM7K good for gaming?

Yes. It has a 144Hz native panel, Auto Game Mode with ALLM, AMD FreeSync Premium Pro and a Game Accelerator mode. Input lag is low enough for competitive play.

Does it support Dolby Vision and Dolby Atmos?

Yes. It handles Dolby Vision IQ, HDR10+, HDR10 and HLG, and its speakers support Dolby Atmos. It is also IMAX Enhanced certified.

How is it different from the QM6K?

The QM7K steps up in brightness, dimming zones and refresh rate, and adds Bang & Olufsen audio. The QM6K is the cheaper, dimmer option.

Can I use it with a soundbar or AV receiver?

Yes. One HDMI input supports eARC, and Bluetooth lets you send audio to headphones or speakers. There are four HDMI inputs in total.

Does it work with Alexa and Apple HomeKit?

Yes. It runs Google TV and works with Google Assistant, Amazon Alexa and Apple HomeKit, plus AirPlay 2 and Chromecast built-in.

Is the 65-inch version right for my room?

It suits viewing distances of roughly 8 to 10 feet. The anti-glare coating helps in bright rooms, but the screen is glossy, so avoid direct light on it.
