Epson Powerlite 74c Multimedia Projector Users Guide

							Setting Up the Projector21
Connecting to a High-End Workstation
Your PowerLite projector is capable of remapping input resolutions 
up to 1600
×1200 pixels (on the PowerLite 74c) or up to 
1280
×1024 pixels (on the PowerLite 54c). Since 1280×1024 pixels 
is the default resolution for most leading workstations, your projector 
is ideal for displaying workstation video output.
There is no standard for workstation video output. Workstations that 
follow the SXGA standard and use the HD15 (standard VGA) 
connector won’t need an adapter cable or any special connection 
device. However, your system may vary; contact your computer dealer 
if you need help connecting your workstation.

Connecting to Video Sources
You can connect a DVD player, VCR, camcorder, laser disc player, 
digital camera, gaming console—such as Microsoft Xbox, Sony 
PlayStation 2, or Nintendo GameCube—or any other compatible 
video source to your projector. You can connect up to two video 
devices at time (or one computer and one video device). 
The projector supports HDTV, NTSC, PAL, and SECAM, and 
automatically detects the video format. It can receive composite video, 
S-Video, and component video. The type of cable you need depends 
on the video source: 
■For composite video, use the RCA A/V cable included with the 
projector. See below. 
■For S-Video, use the S-Video cable supplied with your video 
device or order one from EPSON (ELPSV01). See page 24.
■For RGB video, use the VGA computer cable included with the 
projector. See page 25.
■For component video, you’ll need the optional EPSON 
component video cable (ELPKC19). See page 26.
Connecting a Composite Video Source
Before starting, make sure the projector and your DVD player or 
other video source are turned off.
1. Locate the RCA A/V cable that came with 
your projector.

Using the Projector
Once you’ve set up the projector, you’re ready to turn it on, adjust 
the image, and give your presentation. 
Although you can operate the projector without it, the remote control 
lets you use additional features. See Chapter 3 for instructions on 
using the remote. This chapter covers the following:
■Turning on the projector and other equipment
■Adjusting the image
■Shutting down the projector 
						

							28Using the Projector
Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1. Then turn on your 
projector, as described below.
If you turn on your connected computer or video equipment before 
starting the projector, the projector automatically detects and displays 
the image source. If you turn on the projector first, or have multiple 
pieces of connected equipment, you may have to select the image 
source manually. See page 30.
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Remove the lens cap.
2. Connect one end of the power cord to the projector’s power inlet. 
3. Connect the other end to an electrical outlet. 
The power light on top of the projector turns orange, indicating 
that the projector is receiving power but not yet turned on. Wait 
until the light stops flashing but stays lit orange.
caution
Do not use the projector with 
the lens cap in place. The 
heat generated by the lamp 
can damage it.
