By selecting the screen type in the menus, Aspect Ratio control is reconfigured for that screen type. · For a 4:3 screen; select "4:3" in the "Screen" menu for proper aspect ratio control of 4:3 and 16:9 sources. · For a 16:9 screen; select "16:9" in the "Screen" menu for proper aspect ratio control of 4:3 and 16:9 sources. *Factory default "Screen" setting is "4:3". Notes For screen sizes not indicated on the projection charts, use the formulas below. The ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes. Distances are in inches, for millimeters multiply by 25.4. Distances may vary ±5%. Formulas The Projection Formulas use the image width for calculation. Image width is the same for all aspect ratios, only vertical image size varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to calculate all screen dimensions. Plug in the image width for "W" in the Projection Formulas. Refer to the diagrams and charts for popular screen sizes on page 2 and 3. Definitions: W = Image Width H = Image Height (Size) B = Vertical distance between lens center and screen center C = Throw distance D = Vertical distance between lens center and screen top (screen bottom for desktop application). = Projection angle Projection Formulas: B = 0.5248W - 0.053 C (wide) = 1.5692W ­ 1.978 C (tele) = 1.8836W ­ 1.9 D(4:3) = 0.1498W - 0.053 D(16:9) = 0.24355W - 0.053 (wide) = tan-1 (B/C(wide)) -1 (tele) = tan (B/C(tele)) 4:3 Screen Formulas: W = H x 4/3 H = W x 3/4 Screen Diagonal = W x 5/4 16:9 Screen Formulas: W = H x 16/9 H = W x 9/16 Screen Diagonal = W x 18.35756/16 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. www.necvisualsystems.com LT245 Page 1 of 7 Diagrams and Distance Charts for 4:3 Screens The following diagrams show the relationship between projector position and the screen.
