How to optimize image size and distance

Consult the table below to find the optimal image sizes achievable when the

projector is positioned at a desired distance from the screen.

• SVGA/XGA series

If the projector is 2.0 m from the screen, good image quality is possible for

image sizes between 45" and 50".

Note: Remind as below figure, the space of 99 cm height is

required when located at 2.0 m distance.
