Pro Tips
Short-throw projectors (ratio < 1.0) allow for large images in small rooms.
Always check if the project has 'Lens Shift' which allows moving the image without tilting the projector.
Keystone correction should be avoided if possible, as it degrades image quality and brightness.
Ambient Light Rejecting (ALR) screens are essential if you plan to use a projector in a room with windows.
