How to optimize image size and distance
• SVGA series
Consult the table below to find the optimal image sizes achievable when the
projector is positioned at a desired distance from the screen.
If the projector is 2.0 m from the screen, good image quality is possible for
image sizes between 42" and 50".
Note: Remind as below figure, the space of 87 cm height is
required when located at 2.0 m distance.
