Is the TCL 65S551G good for gaming?

Only casually. It has no VRR and no 120Hz mode, so fast-paced PS5 and Xbox Series X games will not look as smooth as on a gaming-focused TV. It is fine for slower games and cloud streaming.

Does it support Dolby Vision and Dolby Atmos?

It supports Dolby Vision, HDR10+, HDR10 and HLG for picture. Dolby Atmos can be passed through eARC to a compatible soundbar or receiver, but the built-in 20W speakers will not produce a real Atmos effect.

The TV, its two legs, a remote, batteries and a power cable. A wall mount and HDMI cables are not included.

Can I mount it on a wall?

Yes. It is VESA compatible and weighs 35.7 lb without the legs, so a standard 65-inch wall mount rated for that weight works. Get a second person to help lift it.

Is $655.99 a good price?

It is the only new price listed as of November 7, 2026, and it sits at the high end of the model's recent range. With one store listing it, there is no competing price to compare against, so waiting for a sale is reasonable if you are not in a hurry.

Does it work with Apple AirPlay and HomeKit?

Yes. It supports AirPlay 2 and Apple HomeKit, along with Chromecast, Amazon Alexa and Google Home.

Our take on the TCL 65S551G

The TCL 65S551G is a 65-inch 4K LCD TV in TCL's S Class line, running Google TV with Chromecast built in and support for AirPlay 2, Alexa, Google Home and Apple HomeKit. It covers all four major HDR formats (Dolby Vision, HDR10+, HDR10, HLG) and has eARC on HDMI, but it is a 60Hz-class panel with no local dimming, no VRR and no 120Hz support. At $655.99 at Staples as of November 7, 2026, it sits at the top of its recent range; only one store currently lists it new, so there is little price competition to pull it down.
