Basic Troubleshooting

The computer is on but the projector isn’t displaying anything.

Ensure that the cable connection follows our diagram structure.
Make sure the projector’s input is set to “Comp 1” This is the only input that will work correctly. If you are using a laptop or the ELMO, change the inputs on the dial, not on the projector. If the projector is displaying an input other than “Comp 1” (S Video, Comp 2 etc.) Press the “Comp 1” button on the remote to change it back.

The projector is displaying something other than what I want, or I’ve followed the above steps and still don’t see anything.

While holding the Windows key on the keyboard (by the spacebar) press “P” this will bring up the second display settings. Cycle through these settings by pressing the “P” key repeatedly until you’ve reached the setting you want.
- Duplicate displays exactly what is on your computer screen to the other display.
- Extend treats the projector display as a second display. You can use this to drag something like a video or powerpoint onto the project display while keeping your notes on the computer.
Please always change the display back to duplicate when you are finished, this is how most lecturers prefer it.
