Getting StartedENGLISH - 17Setting upYou can adjust the projection size with 1.2x zoom lens. Calculate and define the throw distance as follows.* All measurements above are approximate and may differ slightly from the actual measurements.J Calculation methods for screen dimensionsYou can calculate more detailed screen dimension from the screen diagonal.Screen width (SW) and screen height (SH)SW (m) = SD (") x 0.0203 SH (m) = SD (") x 0.0152Minimum distance (LW) and maximum distance (LT)PT-LB80NTE: LW (m) = 0.0296 x SD (") - 0.039 LT (m) = 0.0358 x SD (") - 0.047PT-LB75NTE: LW (m) = 0.0292 x SD (") - 0.036 LT (m) = 0.0351 x SD (") - 0.044* The results above are approximate and may differ slightly from the actual measurements.Screen size and throw distanceProjection size(4 : 3)Throw distance (L)PT-LB80NTE / LB80EThrow distance (L)PT-LB78E / LB75NTE / LB75EScreen diagonal(SD)Minimum distance(LW)Maximum distance(LT)Minimum distance(LW)Maximum distance(LT)33" (0.84 m) 1.1 m (3'7") 1.1 m (3'7")40" (1.02 m) 1.1 m (3'7") 1.4 m (4'7") 1.1 m (3'7") 1.4 m (4'7")50" (1.27 m) 1.4 m (4'7") 1.7 m (5'6") 1.4 m (4'7") 1.7 m (5'6")60" (1.52 m) 1.7 m (5'6") 2.1 m (6'10") 1.7 m (5'6") 2.1 m (6'10")70" (1.78 m) 2.0 m (6'6") 2.5 m (8'2") 2.0 m (6'6") 2.4 m (7'10")80" (2.03 m) 2.3 m (7'6") 2.8 m (9'2") 2.3 m (7'6") 2.8 m (9'2")90" (2.29 m) 2.6 m (8'6") 3.2 m (10'5") 2.6 m (8'6") 3.1 m (10'2")100" (2.54 m) 2.9 m (9'6") 3.5 m (11'5") 2.9 m (9'6") 3.5 m (11'5")120" (3.05 m) 3.5 m (11'5") 4.2 m (13'9") 3.5 m (11'5") 4.2 m (13'9")150" (3.81 m) 4.4 m (14'5") 5.3 m (17'4") 4.3 m (14'1") 5.2 m (17')200" (5.08 m) 5.9 m (19'4") 7.1 m (23'3") 5.8 m (19') 7.0 m (22'11")250" (6.35 m) 7.4 m (24'3") 8.9 m (29'2") 7.3 m (23'11") 8.7 m (28'6")300" (7.62 m) 8.8 m (28'10") 10.7 m (35'1") 8.7 m (28'6") 10.5 m (34'5")NOTE:• See “Screen size and throw distance for 16:9 aspect ratio” on page 49.• Do not use the projector at a raised or a horizontally tilted position as it may causemalfunction of the projector.• You can tilt the projector body approximately ± 30° vertically. Overtilting may result inshortening the component’s life.• For the best quality of the projection image, install a screen where sun light or room lightdoes not shine directly onto the screen. Close window shades or curtains to block the lights.88.6SDSWSHScreenProjected image
