Our take on the TCL 43Q51BG 43" 4K Ultra HDR Smart QLED Google TV (2024)

The TCL Q51BG is a 43-inch 4K QLED TV running Google TV, with HDR support and the Google Assistant built in. QLED's quantum-dot layer gives it wider color and higher brightness than the plain LED panels most budget 43-inch sets use, and Google TV pulls streaming apps, live TV and voice search into one interface. It suits a bedroom, small living room or secondary set where size and price matter more than deep blacks. Against rivals like the Amazon Fire TV Omni QLED and Hisense QLED sets, it trades some peak brightness and gaming features for the Google TV platform and TCL's familiar value positioning.

Questions and answers

Is this TV good for gaming?

It handles 4K gaming at 60Hz from a console, which is fine for casual play. It lacks a 120Hz panel, variable refresh rate and other features serious gamers look for.

Does it have Google TV or Android TV?

It runs Google TV, the newer interface built on Android TV. That means the Google Play store, Chromecast built in and Google Assistant voice search from the remote.

How many HDMI ports does it have?

It has three HDMI inputs, enough for a console, a streaming stick and a soundbar or receiver. There are also USB ports for drives and accessories.

Is QLED worth it on a 43-inch TV?

QLED adds a quantum-dot layer for wider color and more brightness than standard LED. On a 43-inch set the gain is real but modest, and it still can't match OLED or mini-LED contrast.

Can I mount it on a wall?

Yes, it uses a standard VESA wall mount pattern. Check the bracket size against the set's mounting holes before buying.

Does it support HDR formats like Dolby Vision?

It supports HDR playback, including HDR10 content. Dolby Vision support varies by model and region, so confirm the spec sheet for your version.
