Is the TCL 75Q681F good for movies?

Yes. Full-array local dimming and quantum-dot color give it strong contrast and saturated color for its class. At up to 600 nits it handles HDR, but highlights won't be as bright as on mini-LED sets.

Does it run Google TV or Fire TV?

It runs Fire TV, with the Amazon interface and Alexa voice remote. Most other TCL QLED models use Google TV, so this is the set to pick if you're already in Amazon's ecosystem.

What HDR formats does it support?

TCL lists support for all the major HDR formats, including Dolby Vision and HDR10. That covers most streaming and disc content.

How does it compare with TCL's mini-LED TVs?

Mini-LED models like the QM series have many more dimming zones and higher brightness, so they show less blooming and punchier highlights. The Q681F costs less and still offers local dimming and QLED color.

Is a 75-inch TV too big for my room?

For a typical sofa distance of 8 to 10 feet, 75 inches is a good cinematic size. Measure your wall and stand width first, since the panel is wide and heavy.
