Problems With The Image Or Sound - Epson EMP-7500 Owner's Manual

Problems with the Image or Sound

An image does not appear on the screen.
Check that the power light is on and the lens cover is off.
Also make sure the cables are installed correctly, as
described in Chapter 1.
The correct image source may not be selected. Press the
Source button on the remote control or the control panel
to choose another image source.
Only part of the computer image is displayed.
If the computer's output resolution setting is higher than
1024 x 768, the projector resizes the image. If the
computer output is not compatible with this resizing,
choose a different display setting on the computer. In
Windows 3.x, use Windows Setup in the Main program
group. For a Macintosh, choose Control Panels under the
Apple menu and then choose Monitors. In the Monitors
screen, choose O ptions and make sure Macintosh H i-Res
D isplay or another 1024 x 768 display is selected. For
supported display settings, see "Supported Monitor
D isplays (EMP-7500)" on page 65 or "Supported Monitor
D isplays (EMP-5500)" on page 66.
You also may need to modify existing presentation files if
you created them for a different resolution. See your
software manual for specific information.
The message N O SIGN AL is displayed.
An image source not connected to the projector is selected,
the signal is not being output from the computer, or the
signal is not reaching the projector. Make sure the
connectors are securely attached to both the projector and
the image source. Then check that the image source is
selected correctly. When N O SIGN AL is displayed, you
cannot access the source (computer/ video) menu.
