The controls for most of the EECs are on the top of the podium.
There are three main controls.
Monitor displays black screen
There are several causes of this that can be easily fixed. The most common reason for this is that the Image Source button is incorrect. If someone used a laptop and forgot to press "PC" when done, the screen will be black. Pressing "PC" will fix this immediately.
If the correct source is chosen, then look at the tiny light next to the power switch on the monitor. The color of the light can help track down problems.
Projector won't work
If the projector appears to be operating, but no picture is shown, make sure you have selected the correct source from the console on the top of the podium. The light should be lit. If not, press the button either above or below the name of the item.
If you're using a Macintosh, there may be a problem with the screen refresh rate or resolution. Click on the Apple Menu, then on "System Preferences." Look for "Display Settings." Change the settings; usually if you choose a different refersh rate (listed in Hz), it will fix things. You can also try adjusting the resolution. Different projectors have different settings, so you will have to experiment to find the correct setting.
All EECs are set up for the use of laptops. There are three cables on the podium: a network cable (for Internet only), a video cable, and a sound jack. You will need to plug in the video and sound cables to project them. When you press the Laptop button on the podium control, the laptop image will display on the monitor and on the projector.
If you get a blank screen on the projector when you've pressed the "Laptop" button, make sure you are set to project the image. Laptops usually have a function key that toggles this on and off. The actual key is different depending on the manufacturer; look for a representation of a computer screen or the letters CRT/LCD. Hold down the key marked "Fn" and press the appropriate function key, then release. Wait a moment for the change to take effect.
The video output on a Macintosh is not directly compatible with the projectors. However, every Mac comes with a video adapter. The adapter is required to project from the Mac.
In addition, sometimes the Mac screen resolution is too high for the projector. See "Projector Won't Work" above.
PowerPoint Slow to Display
PowerPoint 2007 searches for the default printer before loading files. This causes a problem if the printer drivers are not on the EEC computer (if you have a different model).
If you have this issue, there is a workaround:
PowerPoint will now display normally. Note: You will need to reverse the process when you get back to your office.
Monitor only shows only shows part of the notebook computer screen.
Make sure you are not set for dual monitors.
Be sure to log off the computer when you're done. Also, if you've used your laptop, set the image source selector to PC so it's ready for the next user.
