You can calculate detailed screen dimensions from the “Screen diagonal”. The unit of all the calculation results is
m. (The results below 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) SH (m) = SD (m) × 0.6 SH (m) = SD (m) × 0.490
Screen width (SW) SW (m) = SD (m) × 0.8 SW (m) = SD (m) × 0.872
Minimum distance (LW)
PT-LB3/PT-LB2 = 1.1496 × SD (m)
-
0.025 = 1.2520 × SD (m)
-
0.011
PT-LB1 = 1.1890 × SD (m)
-
0.035 = 1.2992 × SD (m)
-
0.041
Maximum distance (LT)
PT-LB3/PT-LB2 = 1.3819 × SD (m)
-
0.033 = 1.5079 × SD (m)
-
0.035
PT-LB1 = 1.4094 × SD (m)
-

NOTE:
For best projection image quality, install a screen where sunlight or room lightings do not
shine directly onto the screen. Close window shades or curtains to block the light and turn
off the lightings.
Do not use the projector at a raised or horizontally tilted position. It may cause the
projector to malfunction.
However, you can tilt the projector’s body approximately ±30 ° vertically and ±10 °
horizontally.
Over tilting may result in shortening the component’s life.
Do not cover the air outlet port and air intake ports or place anything within 50 cm (20") near them as this may cause damage
or injury.
