Plugging In
Connect the laptop to the VGA connector, which should be in the small cut-out on top of the podium. Some PCs and most Macs use DVI ports instead of VGA ports, and you'll need to use an adapter (see below) to connect the cable. Laptops that need an adaptor usually come with one, but if not, you should be able to find one at a computer or electronics store. Connect the network cable provided if needed.

Turning On
Turn the projector on by hitting "power" on the remote. The "input" button should default to input1, but you may want to make sure this is set correctly.
Tip
Be aware that it sometimes takes the projectors a little while to warm up and turn on. You should see a blue light through the lens almost immediately, but it may take a little longer for the actual projection to begin. Don't succumb to the temptation to keep hammering away at the power button; you'll just turn it back off.
Powering down when you're finished requires you to hit the power button twice. The first press will ask you to confirm your decision; do so by hitting the power button a second time.
Tip
In room 307 or room 214 , use the touch screen interface embedded in the instructor podium to perform the steps above. Press the button in the upper-left of the touchscreen, and then press the button. Proceed to the next steps.
Setting Display Mode - PC
Many laptops have a Fn key set to change display modes and allow for the use of the projector. Holding down the Fn key (usually located at the bottom left of your keyboard) while pressing the appropriate function key ( F5, F7, F8, etc., at the top of your keyboard) should cycle through several projection modes (display on PC screen only, on PC and projector, on projector only, etc.). The appropriate function key varies from one manufacturer to another. The function key assignments of some common manufacturers are listed below.
Tip
The particular F# key to use should have an icon that looks like a computer and a screen separated by an "/",an "|", or in the case of Dell notebooks, it will have the characters "CRT/LCD."
Table 1. Common Fn Keys for Changing Display Modes
| Manufacturer | Key |
|---|---|
| Acer | Fn + F5 |
| Dell | Fn + F8 |
| HP (not all models) | Fn + F5 |
| IBM ThinkPad | Fn + F7 |
| Sony | Fn + F7 |
| Toshiba | Fn + F5 |
Setting Screen Resolution - PC
If you have set the display mode (or if your laptop doesn't have an Fn-F# combo), and it is still not displaying correctly, you may need to manually adjust the laptop's screen resolution to a level the projector can handle. CCI (IBM) laptops allow you to select from multiple display modes by using Fn + F7 (see above). The default resolution for many newer laptops is often higher than 1024 x 768, so you may need to change your computer's resolution.
Set your laptop's resolution to 1024x768 by doing the following:
an empty portion of your desktop background and choose
Click on the tab and make sure the screen resolution is set to 1024x768
Click on if you made any changes and then .
Setting Display Mode and Screen Resolution - Mac
Macs should detect the necessary display and resolution settings and adjust automatically, but if not, go to and select . Select the button, and it will detect the projector and automatically adjust the screen resolution. You may also select a different resolution at this time.
Additional Troubleshooting
More often than not, you can get away with simply popping in the VGA cable and hitting the appropriate Fn key to reset your resolution, but sometimes you may need to have the cable connected at start-up in order for the appropriate drivers to load. If the above still won't get the display up through the projector, try powering down, connecting the VGA or DVI cable and powering back up.
