Consult the table below to find the optimal image sizes achievable when the projector is positioned at a desired distance from the screen.
•X111/X1140/X1140A/X1240
If the projector is 3 m from the screen, good image quality is possible for image sizes between 72" and 79".
Note: Remind as below figure, the space of 126 cm height is required when the projector is located at 3 m distance.
