Chapter 2 Getting Started — Setting upENGLISH - 35Projection distance by Projection LensA ±5 % error in listed projection distances may occur.In addition, when [KEYSTONE] is used, distance is corrected to become smaller than the specified screen size.For PT-EZ770Zr When the screen aspect ratio is 16:10(Unit: m)Lens type Standardzoom lensOptional lensHeight position (H)*2Fixed-focuslensShort focuszoom lensLong focuszoom lensUltra longfocus zoomlensProjection Lens Model No. — ET-ELW21 ET-ELW20 ET-ELT20 ET-ELT21 Standard zoomlens/ET-ELW20/ET-ELT20/ET-ELT21ET-ELW21(Fixed)Throw ratio*1 1.7-2.8:1 0.8:1 1.3-1.7:1 2.8-4.6:1 4.6-7.2:1Projected image size Projection distance (L)Diagonal (SD) Height(SH)Width(SW)Min.(LW)Max.(LT) Fixed Min.(LW)Max.(LT)Min.(LW)Max.(LT)Min.(LW)Max.(LT)1.02 (40") 0.538 0.862 1.36 2.35 0.63 1.02 1.41 2.29 3.81 3.72 6.03 -0.05 - 0.59 0.271.27 (50") 0.673 1.077 1.71 2.95 0.80 1.29 1.77 2.89 4.79 4.70 7.59 - 0.07 - 0.74 0.341.52 (60") 0.808 1.292 2.06 3.55 0.97 1.55 2.14 3.49 5.77 5.68 9.15 -0.08 - 0.89 0.401.78 (70") 0.942 1.506 2.42 4.15 1.14 1.82 2.50 4.09 6.75 6.66 10.71 -0.09 - 1.04 0.472.03 (80") 1.077 1.723 2.77 4.76 1.32 2.09 2.87 4.69 7.73 7.64 12.27 -0.11 - 1.18 0.542.29 (90") 1.212 1.939 3.12 5.36 1.49 2.36 3.23 5.30 8.71 8.63 13.83 - 0.12 - 1.33 0.612.54 (100") 1.346 2.154 3.48 5.96 1.66 2.63 3.60 5.90 9.69 9.61 15.39 -0.13 - 1.48 0.673.05 (120") 1.615 2.585 4.18 7.16 2.00 3.16 4.32 7.10 11.65 11.57 18.51 -0.16 - 1.78 0.813.81 (150") 2.019 3.231 5.24 8.96 2.52 3.96 5.42 8.90 14.59 14.52 23.19 - 0.20 - 2.22 1.015.08 (200") 2.692 4.308 7.01 11.96 3.38 5.31 7.25 11.91 19.49 19.43 30.99 -0.27 - 2.96 1.356.35 (250") 3.365 5.385 8.77 14.96 4.24 6.65 9.07 14.91 24.39 24.34 38.79 - 0.34 - 3.70 1.687.62 (300") 4.039 6.462 10.54 17.97 5.10 7.99 10.9 17.92 29.29 29.25 46.59 - 0.40 - 4.44 2.028.89 (350") 4.712 7.539 12.30 20.97 5.95 9.33 12.73 20.92 34.19 34.16 54.39 -0.47 - 5.18 2.3610.16 (400") 5.385 8.616 14.07 23.97 6.81 10.67 14.55 23.93 39.09 39.07 62.19 -0.54 - 5.92 2.69*1 The throw ratio is based on the value during projection with the projected image size of 2.03 m (80").*2 When the fixed-focus lens (Model No.: ET-ELW21) is attached, the lens shift is not possible.
