Setting up Screen size and throw distance You can adjust the projection size with 2.0x zoom lens. Calculate and define the throw distance as follows. SH SD Projected image (Shown as 16:9 size) SW Screen Getting Started All measurements and the calculation results bellow are approximate and may differ from the actual measurements. Throw distance (16 : 9) Throw distance (2.35 : 1) Screen Diagonal Minimum distance Maximum distance Minimum distance Maximum distance (SD) (LW) (LT) (LW) (LT) 1.02 m 1.27 m 1.52 m 1.78 m 2.03 m 2.29 m 2.54 m 3.05 m 3.81 m 5.08 m (40") (50") (60") (70") (80") (90") (100") (120") (150") (200") 1.2 m 1.5 m 1.8 m 2.1 m 2.4 m 2.7 m 3.0 m 3.6 m 4.5 m 6.0 m (3'11'') (4'11'') (5'10'') (6'10'') (7'10'') (8'10'') (9'10'') (11'9'') (14'9'') (19'8'') 2.3 m 2.9 m 3.5 m 4.1 m 4.7 m 5.3 m 5.9 m 7.2 m 9.0 m 12.0 m (7'6'') (9'6'') (11'5'') (13'5'') (15'5'') (17'4'') (19'4'') (23'7'') (29'6'') (39'4'') 1.3 m 1.6 m 1.9 m 2.2 m 2.6 m 2.9 m 3.2 m 3.8 m 4.8 m 6.4 m (4'3'') (5'2'') (6'2'') (7'2'') (8'6'') (9'6'') (10'5'') (12'5'') (15'8'') (20'11'') 2.3 m 2.8 m 3.3 m 3.8 m 4.2 m 4.7 m 5.7 m 7.1 m 9.6 m (7'6'') (9'2'') (10'9'') (12'5'') (13'9'') (15'5'') (18'8'') (23'3'') (31'5'') J Calculation methods for screen dimensions You can calculate more detailed screen dimension from the screen diagonal. 16 : 9 size Screen width (SW) and screen height (SH) SW (m)= SD (m) x 0.872 SH (m) = SD (m) x 0.490 Minimum distance (LW) and maximum distance (LT) LW (m) = SD (m) x 1.189 - 0.04 LT (m) = SD (m) x 2.378 - 0.05 2.35 : 1 size Screen width (SW) and screen height (SH) SW (m)= SD (m) x 0.920 SH (m) = SD (m) x 0.392 Minimum distance (LW) and maximum distance (LT) LW (m) = SD (m) x 1.256 - 0.04 LT (m) = SD (m) x 1.899 - 0.05 NOTE: • Do not use the projector at a raised or a horizontally tilted position as it may cause +30° malfunction of the projector. • Make sure the projector lens surface is parallel with the screen. You can tilt the projector -30° body less than 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. 14 - ENGLISH
