1.) My projector is not getting a signal or displaying a picture. Why? When setting up your equipment, it is very important that you turn on the projector first. You will see a blank projection image, now turn on the computer. When using a laptop computer you may need to disable your computer's display screen. To do this, locate the "function" key at the top of your keypad that reads "LCD," "CRT," or it may have an icon that resembles a computer monitor. By pressing the "FN" key and the corresponding "function" key you will be able to display the image from the projector only. This is known as "toggling" the image.     2.) My computer's projected image is either missing information from the top/bottom, compressed from left/right, or doesn't appear at all. What's wrong? In most cases, to get a matching image, the computer's resolution must match the projector's native resolution. To configure the computer's external video signal resolution, follow these steps: Connect the projector to the computer using the appropriate cable and power the projector on before the computer. In Windows 95/98/NT, select "Control Panel", "Display Icon", "Settings", "Desktop Area" to adjust the resolution to 1024 x 768 (XGA) or 800x600 (SVGA). In Windows 3.1, select "Windows Setup" from the "Main" program group, and change the display driver, eg. SVGA (800 x 600). Configure the computer/laptop to display video only on the external video port. This is usually done through a combination of keystrokes (such as FN+F4) or a hardware setup program (consult your computer documentation for details). You may have to restart Windows for the changes to take affect. Also note compatible refresh rates, for example 56Hz or 60Hz for SVGA signals, between your computer and projector. Most projectors can manage a wide range of refresh rates.   3.) I have a new Compaq laptop and the projected image is too big for the screen -- how do I fit it? Your laptop may have a separate control for external display. In Windows, go to Control Panel, Display and click on Compaq, Advanced, CRT. In the CRT settings, change the display to either 800x600 or 1024x768 to match the projector.     4.) With the Mac PowerBook, how can I display both internal and external video at the same time? The method of controlling whether the internal screen works in addition to the projector is called "video mirroring." To control video mirroring, in Control Panel, PowerBook Display, set Video Mirroring to ON for both internal and external -OR- OFF for image on external panel only or internal only, depending on monitor selection in Monitors. If running Mac OS 8.0 or higher, set your Powerbook display at 800x600 or 1024x768 at 60 hz.   5.) How do I set up the remote mouse? Most projectors can emulate a mouse when connected to a computer using one of the remote mouse cables (serial, PS/2 or Mac ADB). Refer to the projector user guide too see if remote mouse is available. Connect the mouse cable between the projector and the computer/laptop. Note: If using a PC laptop, the best choice is the PS/2 style connection. On a Mac, use the ADB cable. Check the mouse driver in Windows: Windows 95/98: In Control Panel, click on Mouse and check the driver. The driver should be set on either Standard PS/2 or Standard Serial depending on which cable is used. Windows 3.1: In Windows Setup, the mouse driver should be set to Microsoft or IBM PS/2 mouse (when using either the serial or PS/2 remote cable). Turn on equipment. With the Mouse Cable and Mouse Driver setup, turn on the projector and restart the computer. If the steps above do not activate the remote mouse, follow the troubleshooting steps below: Verify an external mouse works in the same port that is used for the projector's mouse. (Example, if using the serial port on your PC, test the port with a 9-pin serial mouse, etc.). Verify that the non-computer control functions on the remote work. (eg: Can it bring up the projector menus?) If not, try replacing the batteries. If unable to operate the remote mouse, power down the projector and wait one minute (leave PC/MAC powered on). Turn the projector back on. The remote mouse should now work. Macintosh: Try loading the Macintosh without any extensions loading. Verify that AppleTalk is disabled. If necessary, disable any modems.     Source code:
