Diagrams and Distance Charts for 16:9 Screens The following diagram shows the relationship between projector position and the screen. Refer to the chart below for data. Distances are in inches. For millimeters multiply by 25.4. Ceiling Mounted Lens Ctr C Throw Distance 6.5" 5.8" α D Screen Top B Screen Ctr Desktop Screen Ctr C Throw Distance Lens offset from mount center 2.5" B Screen Bottom D Lens Ctr α 3.3" Distance chart for popular 16:9 screens Vertical Position for a 16:9 screen The Vertical Position adjustment moves the 16:9 image up and down in the unused portion of the 4:3 panel. This adjustment is only available when the projector is set for '16:9' in the 'Screen' menu. The range of Vertical Position is dependent on aspect ratio and 3D Reform used. If 3D Reform is not used, the approximate range of Vertical Position is +/-0.167H (H=Screen Height) when using a 16:9 screen. Note: For screen sizes not indicated on the chart, use the formulas on page 1. www.necvisualsystems.com Screen Size (16:9) B Diag W H inches inches inches inches 28 24 13.5 12.6 55 48 27 25.2 60 53 29.5 27.6 73 64 36 33.6 82.6 72 40.5 37.8 92 80 45 42.0 100 87 49 45.7 106 92 52 48.3 110 96 54 50.4 119 104 58.5 54.6 123 107 60 56.2 133 116 65 60.9 135 118 66 62.0 159.5 139 78 73.0 161 140 79 73.5 459 400 225 210.1 C wide - tele inches 45.6 - 56.0 93.5 - 114.1 102.5 - 125.0 125.5 - 152.9 141.5 - 172.2 157.4 - 191.6 171.4 - 208.5 181.4 - 220.7 189.4 - 230.3 205.4 - 249.7 211.4 - 257.0 229.3 - 278.8 233.3 - 283.6 275.3 - 334.4 277.3 - 336.9 796.7 - 966.4 D inches 5.8 11.7 12.8 15.6 17.5 19.5 21.2 22.4 23.4 25.4 26.1 28.3 28.8 33.9 34.2 97.6 α wide - tele degrees 15.4 - 12.7 15.1 - 12.4 15.0 - 12.4 15.0 - 12.4 15.0 - 12.4 14.9 - 12.4 14.9 - 12.4 14.9 - 12.3 14.9 - 12.3 14.9 - 12.3 14.9 - 12.3 14.9 - 12.3 14.9 - 12.3 14.9 - 12.3 14.9 - 12.3 14.8 - 12.3 LT265 Page 3 of 7
