Calculation methods for screen dimensions

You can calculate more detailed screen dimension from the screen diagonal. (Unit: m)

Projection size(4:3)		Projection size(16:9)
SH	= SD X 0.0152	SH	= SD X 0.0125
SW	= SD X 0.0203	SW	= SD X 0.0221
LW	= 0.0307 X SD - 0.031	LW	= 0.0335 X SD - 0.0315
LT	= 0.0371 X SD - 0.029	LT	= 0.0405 X SD - 0.0365

* The results above are approximate and may differ slightly from the actual measurements.

NOTE:

• Do not use the projector at a raised or a horizontally tilted position as it may cause malfunction of the projector.

• Make sure the projector lens surface is parallel with the screen. You can tilt the projector body approximately ± 30° vertically. Overtilting may result in shortening the component’s life.

•For the best quality of the projection image, install a screen where sun light or room light does not shine directly onto the screen. Close window shades or curtains to block the lights.
