You can calculate more detailed screen dimensions from the screen diagonal.

 

 

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

 

 

If the projection size is SD,

 

 

 

 

 

 

 

 

 

For 4:3 aspect ratio

 

For 16:9 aspect ratio

Screen height (SH)

 

= SD (m) × 0.0152

 

= SD (m) × 0.0125

 

Screen width (SW)

 

= SD (m) × 0.0203

 

= SD (m) × 0.0221

 

Minimum distance (LW)

 

= 0.0292 × SD (m) - 0.036

 

= 0.0318 × SD (m) - 0.022

Maximum distance (LT)

 

= 0.0351 × SD (m) - 0.044

 

= 0.0383 × SD (m) - 0.046

Note

zzFor the best quality of the projection image, install a screen where sunlight or room light does not shine directly onto the screen. Close window shades or curtains to block the light and turn off the lamps.

zzDo not use the projector at a raised or a horizontally tilted position. Doing so may cause malfunction of the projector.

You can tilt the projector body approximately ±30 ° vertically and ±10 °

horizontally. Overtilting may result in shortening the component’s life.

zzDo not cover the air outlet port and air intake ports or place anything within 50 cm (20") of them as this may cause damage or injury.
