Is this TV good for dark-room movie watching?

It is a standard LED set without full-array local dimming, so blacks look gray in a dark room. It performs better in a bright room or for daytime viewing.

Does it support Dolby Vision and HDR10?

Yes. TCL lists Dolby Vision HDR support, and the set handles standard HDR10 content from streaming apps and discs.

What smart platform does it run?

Google TV. It includes the major streaming apps, Google Assistant voice control and Google Cast for sending content from a phone.

How does it compare with TCL's QM-series Mini-LED TVs?

The QM series adds Mini-LED backlighting and local dimming for much better contrast and brightness. This model is the larger, simpler LED option.

What is included in the box?

The TV, a stand, a remote and the power cable. A wall mount is not included and must be bought separately for wall installation.

Will an 85-inch TV fit my room?

Measure the wall or stand space first. An 85-inch set is roughly 6 feet wide, so it needs a wide, sturdy surface and a viewing distance of around 8 to 12 feet.
