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

 

z

For 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.

Do 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.

Do not cover the air outlet port and air intake ports or place anything within
