Q: How do I connect my laptop video to the Geology classroom projectors?
A: The following instructions should assist you in getting your portable/laptop computer's video connected to the Geology classroom projectors.

Quick Procedure

  1. If required, select the appropriate video adapter and attach it to the end of the video cable.
  2. Turn the projector on using the power button on the remote control for the projector.
  3. In classrooms with Casio projectors, press the Input selector button on the remote to select the Computer 1 input.
  4. Attach the video cable/adapter to your computer, then wake your computer if it is asleep.
  5. Wait about 15 seconds to see if the projector begins displaying video from your computer.
  6. If what you see on the projection screen is what you expected, then you succeeded and are done.
  7. If what you see is your desktop or wallpaper pattern but nothing else then turn on Mirroring or dual display clone mode.
  8. Should the projected image be off-color, green or blue or yellow tint, ensure the video cable is firmly connected.

Full Procedure

  1. A VGA video cable should be hanging on or near the video cabinet located at the front of each classroom. Attached near the end of the video cable are a variety of video adapters. If your computer requires a video adapter, select the one for your computer and attach it to the end of the video cable.

  2. Turn the projector on using the power button, generally in the upper right-hand corner of the remote control for the projector, except for the Panasonic projector remote in the iMac Classroom -- upper-left.

  3. On the Casio remotes in the classrooms and in the Moores Room, EPS 1119, press the Input selector button in the upper left-hand corner of the remote to select the Computer 1 input, if it is not already set.

  4. If you have a Mac, wake your computer if it is asleep, and then attach the video cable/adapter to your computer.

    If you have a PC, attach the video cable/adapter to your computer, then wake your computer if it is asleep.

  5. Wait about 15 seconds to see if the projector begins displaying video from your computer.

  6. If what you see on the projection screen is what you expected, then you succeeded and are done.

    If what you see is your desktop or wallpaper pattern but nothing else, then your computer is probably in Extended Desktop mode but you want it to be in Mirroring mode.

    Here's how to get your computer into Mirroring mode:
    On a Mac:

    • Use System PreferencesDisplaysArrangement to enable the Mirror Displays option. If you do not see two display screens in the Arrangement window, click the Detect Displays button in the lower-right corner.

    • If you are using OS X 10.8 Mountain Lion, or later you will need to press the keyboard option key to get the Detect Displays button to appear. Detect Displays will be displayed while the option key is held down.

    • Should the projected image be off-color, green or blue or yellow tint, ensure the video cable is firmly connected.

    On a PC:

    • If you have a Windows 7 or Windows 8 computer: Press and hold the Windows key + P (or click on the start button, type Projector and click on Connect to Projector). In the window that appears select Duplicate.

    • If you have an XP computer: Press and hold Fn+F8 (see the table below for the appropriate function key combination for your hardware). The key labeled Fn is in the lower left corner of the keyboard and the function key labeled F8 is at the top of the keyboard. This will work on most Dell computers (check the following table or your manual for other brands).
      NEC, PanasonicFn+F3
      Acer, HP, Sharp, ToshibaFn+F5
      Lenovo, SonyFn+F7
      Dell, EpsonFn+F8
      FujitsuFn+F10
    • If the projected image is displaying your wallpaper and nothing else, try pressing the Fn+F8 keys again. Each time you press Fn+F8 a different mode is selected. There are normally three display modes available; laptop display only, laptop and projected image, or projected image only. Please be aware that switching between modes can take a few seconds to occur.

    • Should the projected image be off-color, green or blue or yellow tint, ensure the video cable is firmly connected.

    • If the problem persists, right-click on the desktop.
      - If you see an NVidia option, follow the instructions in the NVIDIA Control Panel Settings section below.
      - If you see an Intel option, follow the instructions at Intel Graphics - How to enable Intel dual display clone mode.

    • If the projected image is cut off on the sides or bottom, set the resolution to 1024 x 768.
      - To set your resolution in Vista or Windows 7: Right-click on the desktop and choose Screen Resolution.
      - To set your resolution in XP: Right-click on the desktop, click Properties, click the Settings tab.
      More detailed instructions for changing the resolution are available online for XP and Vista/Windows 7.

    • If this does not correct the problem, be sure the video cable is connected correctly and then reboot.
