Our take on the TCL 65Q51K Q Series 4K Ultra HDR Smart QLED Google TV
The TCL 65Q51K is a 65-inch 4K QLED TV running Google TV. Quantum dot film widens color over a standard LED set, and HDR support covers the major formats. It suits buyers who want a big-screen smart TV with Google's app and voice interface without stepping up to mini-LED. Against mini-LED rivals it gives up brightness and contrast in dark scenes, and its 60Hz panel is not built for fast gaming.

What reviewers say
Owners of TCL's Q-series QLED sets generally praise the color and the Google TV interface for the money. Complaints center on black-level uniformity, brightness in bright rooms, and sound from the built-in speakers.
- Picture colorPraisedOwners say the QLED panel gives strong, saturated color for the class.
- Black levelsCriticisedViewers report blooming and gray blacks in dark scenes compared with mini-LED sets.
- BrightnessMixedIt holds up in dim rooms but washes out somewhat in very bright ones.
Questions and answers
- Is this a mini-LED TV?
- No. It is a QLED set with standard LED backlighting, not mini-LED. Mini-LED models in TCL's line offer higher brightness and better contrast.
- Does it support Dolby Vision and HDR10+?
- It supports HDR playback across the common formats. Check the set's spec sheet for the exact list before buying if a specific format matters to you.
- Is it good for gaming?
- It has a 60Hz panel, so it suits casual console play but not high-frame-rate gaming. Serious gamers should look at 120Hz models.
- What is in the box?
- The TV, a stand, a voice remote, and power and documentation. A wall mount and cables are not included.
- Do I need a soundbar?
- Most owners pair one. The built-in speakers are serviceable for news but thin for movies.
- How does it compare with the QM series?
- The QM series uses mini-LED for higher brightness and deeper blacks. This Q-series set trades some of that performance for a simpler backlight.
