Positioning your projector Choosing a location Before choosing an installation location for your projector, take the following factors into consideration: • Size and position of your screen • Electrical outlet location • Location and distance between the projector and the rest of your equipment You can install your projector in the following ways. 1. Front Table 2. Rear Table Select this location with the projector placed on the table in front of the screen.
Obtaining a preferred projected image size The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size. Projection dimensions 16:9 Screen diagonal Screen Center of lens H W Vertical Offset Projection distance • The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio Screen size Distance from screen (mm) Diagonal Min length H (mm) W (mm) 664 Max length (max. zoom) Average (min.
If your measured projection distance is 5000 mm, the closest match in the "Distance from screen (mm)" column is 4893 mm. Looking across this row shows that a 170'' (about 4.3 m) screen is required. • All measurements are approximate and may vary from the actual sizes.
• Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater is used, the temperature around the ceiling/wall may be higher than expected. • Read the user manual for the mounting kit about the range of torque. Tightening with torque exceeding the recommended range may cause damage to the projector and subsequently falling off. • Make sure the power outlet is at an accessible height so that you can easily shut down the projector.
Adjusting the projected image Adjusting the projection angle If the projector is not placed on a flat surface or the screen and the projector are not perpendicular to each other, the projected image becomes trapezoidal.
