Should I buy a projector instead of a TV for movies?

Yes—buy a projector instead of a TV if your main goal is a big, theater-like movie image and you can control the room lighting. For most people, a TV is still the better everyday screen because it is brighter, simpler, and better for daytime viewing.

Best rule of thumb:

1. Choose a projector if you want a 100–120 inch movie experience, mostly watch at night, have space for a screen or blank wall, and don’t mind setup.
2. Choose a TV if you watch in a bright room, use it for sports/news/gaming/daytime viewing, or want the easiest, most consistent picture.
3. Consider both if you can: a TV for casual viewing and a projector for movie nights is often the best setup.

If movies are the priority, I’d only replace the TV with a projector if you have a darker room and are genuinely aiming for a much larger image than a 65–85 inch TV.
