Is a projector cheaper than a TV for large screens?

For screens above 85 inches, projectors are significantly cheaper per inch. A 100-inch projected image costs a fraction of a 98-inch TV. Below 75 inches, TVs are more cost-effective and require no maintenance.

Does room brightness matter for projectors?

Yes. Projectors perform best in dark or light-controlled rooms. In bright rooms with ambient light, even high-lumen projectors look washed out compared to a modern TV.
