Is the TCL Q77K good for gaming?

Yes. The 144Hz native refresh rate keeps fast motion smooth, and the HDMI inputs accept high frame-rate console output. It lacks the variable refresh rate and low-latency features of TCL's Mini LED gaming sets, but it covers the basics well.

How does the Q77K compare with TCL's Mini LED TVs?

The Q77K uses a standard backlight with an HVA panel, while TCL's Mini LED models add many more dimming zones for deeper blacks and less blooming. The Q77K costs less and still offers QLED color and 144Hz, so it is the value pick of the two.

Does it support Dolby Vision and HDR10+?

Yes. HDR PRO+ covers Dolby Vision, HDR10+, HDR10 and HLG, so most streaming and disc sources will play in their best available HDR format.

What size is the screen and will it fit my wall?

It is a 75-inch class screen, roughly 65 inches wide before the stand. Measure your wall or media console and check the VESA pattern before mounting, since a set this size needs a sturdy mount.

The TV, a backlit voice remote, a stand and the power cable. A wall mount and HDMI cables are not included.

Is the Q77K worth it over a cheaper 4K TV?

The QLED layer, HVA contrast and 144Hz panel put it above basic 4K sets for color, motion and HDR. If you mainly watch in a bright room at wide angles, a set with an IPS panel may suit you better.
