The projected image is cropped or the text quality is poor.The projected image is cropped or the text quality is poor.
If the entire computer image is not projected onto the screen or if the text appears choppy, try the following:
Adjust screen area For optimal image quality, adjust the screen area of the computerÆs display settings to match the projectorÆs native resolution. The Projector Wizard will help you set this up correctly.
Disable laptop display With certain laptops, you might need to disable the laptop display to obtain the best image, especially when the native resolution of the laptop exceeds the native resolution of the projector.
Get font smoothing Install Windows 98 with font smoothing or get Microsoft Plus! for Windows. Font smoothing will automatically generate a cleaner font outline on your laptop and on the projector.
Refer to your projector documentation for the optimum or native resolution setting for your projector model. If you cannot find this information or are uncertain, most projectors support a maximum of 800 x 600 pixels (SVGA resolution).
The projected image goes blank during periods of computer inactivity.
This might be caused by a power-saving utility on the computer that disables the video output signal after a specified period of inactivity.
Disable all power-saving utility programs and screen savers on the computer to prevent signal interruption. These can sometimes be disabled by using the Power and Display icons in Control Panel (Windows Start menu, Settings submenu). On some computers, it might be necessary to check the system BIOS settings. See your computer documentation if necessary.
The projected image is dimmer than it used to be.
Some projectors use a metal halide lamp, the brightness of which will fade over time. Check your projector documentation for information regarding lamp timers. If the lamp life is expired, replace the lamp for maximum brightness.
The projected image is not rectangular.
To fix this, try one or both of the following:
Check the projector Make sure the projector is perpendicular to the viewing screen.
Adjust elevator mechanism Raise or lower the elevating mechanism on the projector to obtain a rectangular image. You might need to place the projector on a higher or lower surface to completely eliminate the distortion.
The projected image displays vertical lines, "bleeding," or spots.
Try one or more of the following:
No sound is emitted from the projector.
Try one or more of the following:
Volume adjustments Adjust the volume on the projector and the laptop. The volume must be turned up and the mute turned off on both the video source and the projector.
Audio input connections Make sure your audio input connectors are working.
No image or light is projected onto the screen.
Try one or more of the following:
Power source Make sure the projector has an active power source.
Projector lamp If you have power to the projector but the lamp still isn't working, try the following:
Video connection cable Check for bent pins on the video connection cable between the video source and the projector.
Lens cap Make sure you have removed the lens cap on the lens in the front of the projector.
The computer desktop image isn't projected onto the screen.
This is usually caused by a lack of signal transmission between the computer and the projector.
If you are using a laptop, you might need to manually activate or deactivate the laptop video port in order for your laptop to send a signal to the projector.
State 1: Activation of laptop display only
State 2: Activation of external video port only
State 3: Activation of both the laptop display and the external video port simultaneously
The command for activating the video port will toggle through these three options. If activation of the video port does not cause an image to be projected, wait 45 seconds and then press the function keys again.
