Is the TCL 98QM850G good for movies?

Yes. The large screen, mini-LED brightness and HDR10 support give movies a cinematic look. A separate sound system helps because the built-in speakers are modest for Atmos.

How does it compare with TCL's smaller QM8 models?

It shares the QLED and mini-LED approach but at a much larger size. The bigger panel gives more immersion, while smaller models are easier to place and mount.

Does it support Dolby Atmos?

Yes, Dolby Atmos is supported. The built-in speakers can only approximate the effect, so a soundbar or AV receiver gets closer to real overhead sound.

What smart platform does it use?

It runs Google TV, with hands-free voice control and access to major streaming apps. The interface is the same family used across TCL's Google TV sets.

Will a 98-inch TV fit my room?

Measure the wall or stand first. A 98-inch set is roughly seven feet wide, so it needs a wide space and a viewing distance of several feet to feel comfortable.

Is it worth it over a projector?

For everyday viewing in a room with normal light, the bright QLED panel is simpler and sharper than most projectors. A projector still wins for screens well beyond 100 inches.
