Frequently asked questions
- How dark does the room need to be?
- Projectors look best in controlled lighting. Brighter models cope with some ambient light, but a darker room always improves contrast and perceived image quality.
- What is throw ratio and why does it matter?
- Throw ratio relates projector-to-screen distance to image width. It determines how far back you mount the unit, so check it against your room before buying.
- Do I need a dedicated screen?
- A screen improves brightness and uniformity over a painted wall, but a smooth, light wall can work. A proper screen yields the most consistent results.
