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.
