  1. Start with the computer off
  2. Plug in all the cables
  3. Turn on the projector.
  4. Once the projector fan starts running, turn on your computer.



  1. Power:  Check that the power for both the projector and computer is turned on. If it is a cart, make sure the entire cart is plugged in.
  2. Cables: Check the cables. Are they all tight? Are they plugged in to the proper place? On a mac, pull the white display adapter out of the side of the computer. Wait 3 seconds. Put the white display back in to the side of the computer.
  3. Source: Press the source button on the projector or the projector remote. For a computer you will typically want the source to be “RGB” or "RGB1"
  4. Mirroring / Cloned Display:
    1. Mirroring / Cloned Display (PC): Hold down the Fn (Function) key while pressing the Display Function key (usually F5, F6 or F8). Wait about 10 seconds to allow the projector to react. You may need to repeat this process to get the correct setting.
    2. Mirroring / Cloned Display (Mac): From the Apple menu, select “System Preferences.” Then click “Display.” Click the “arrangement” tab and then select “mirror displays.”
  5. Display Resolution:
    1. Display Resolution (PC): Check the display resolution. Right-click on the desktop. Look for a video driver software (often called N- Vidia Display Settings). If no special software is present, click “Properties” and then click “Settings.” Set the resolution to 1024 by 768 at 60 Hz.
    2. Display Resolution (Mac): From the Apple menu, select “System Preferences.” Then click “Display.” Set the display resolution to 1024 by 768 at 60 Hz.
  6. Restart: If none of the the other tips have worked, the next option is to restart the computer. When you do this, make sure to keep the projector turned on.
