EPSON PowerLite 7800p Projector

Connecting the Projector

You can connect the projector to three computer sources or four video sources—up to a total of four sources altogether. You can include an independent sound channel for each source. (See the Quick Setup poster or the User’s Guide for complete setup instructions.)

Note: The preview feature lets you see all the sources at a glance, so you can easily switch among them. See page 5.

Playing Sound Through the Projector

You can play sound through the projector’s speaker system or you can attach an external speaker system.

Two types of audio cables are included with the projector:

❏If your computer or video equipment is connected to the Computer or DVI port, use the stereo mini-jack cable.

❏If your equipment is connected to the Video or S-Videoport, or to the BNC ports, use the RCA-style audio cable.

Note that the projector’s Computer and BNC ports accept a variety of input signals. If you’re connecting to one of these ports, you’ll need to make sure that the correct input signal setting is selected, or your image won’t display properly.

To change the input signal setting, do the following:

1.After turning on the projector, press the Menu button. The menu screen appears.

2.Select the Setting menu.

3.Change the Computer Input or BNC Input setting as needed to match the signal generated by your computer or video equipment. (See the User’s Guide for more information.)

You can also cycle through the settings by repeatedly pressing the source button for your device on the remote control.

Using the Remote Control as a Wireless Mouse

If you’ve connected a computer to the projector, you can use the projector’s remote control as a wireless mouse by connecting the USB cable that came with the projector. The wireless mouse function is supported on systems with a USB port running Windows XP, 98, 2000, or Me; or Macintosh OS 8.6 to OS X 10.2. See the User’s Guide for more information.

Viewing Images on an External Monitor

You can use an external monitor to display images from any connected computer source. This lets you view your presentation close-up, as well as on the projection screen.

Note: Some LCD monitors may not be able to display the image correctly. If you have trouble displaying the image, connect a multiscan monitor. If you’re projecting computer images, make sure the computer’s refresh rate is set to 65 Hz or greater.

To use an external monitor, connect it to the projector’s Monitor Out port, as shown:
