(Actual projection distances and screen sizes may vary)
The image should be projected onto a flat surface screen with high
reflectivity to get a bright and undistorted image.
The best viewing results are obtained in a dimmed room with no direct
sunlight shining in. Try to ensure also that the projected image is visible
to the whole audience by placing source equipment where it will not
obscure viewing. The LCD projector is provided with extra long cables
for this purpose.
