CHAPTER 7: Troubleshooting

• Type of connection used—You can connect the
computer video output to a TV. However, the
connection type has an affect on the video quality. The
Media Center has two video outputs:
• VGA—If your TV includes a VGA port, connect the
VGA cable from the computer’s VGA (monitor) port
to the TV’s VGA In port for the best quality. Many
TVs do not have a VGA port.
• S-Video—If your TV does not have a VGA port, but
includes an S-Video port, connect the S-Video cable
from the computer’s S-Video Out port to the TV’s
S-Video In port. S-Video display quality is usually
good for TV images. The display quality for the
computer functions, however, is not as good as VGA
output. S-Video display output is not optimized for
computer video display.
• Quality of video cables—Poor quality or the incorrect
type of video cables can cause problems and affect the
video quality. Gateway recommends using high-quality
video cables that can be purchased from
www.gateway.com
.
• Screen resolution—Many TVs cannot display the high
resolution that your computer’s video signal uses, and
may shift, scramble, or scroll the picture. For a better
picture on a TV display, you may need to lower the
computer’s screen resolution to 800 × 600 or 640 × 480.
For more information about changing the screen
resolution, see the “Customizing Windows” chapter in
the online User Guide.
• Size of display device—Small computer displays for
standard computer applications are generally not
optimized for motion video playback. Although they
offer excellent resolutions and refresh rates, they are
designed to make static white backgrounds with black
text look readable. Some small display devices do not
make colorful motion video look its best. Generally,
video will look better on a larger display device.
• Age of the TV—Newer TVs usually have more
advanced features, produce a better quality picture,
and support higher screen resolutions. The Media
Center video display will likely be better on a newer
model TV.
Important
Cable connections must be made correctly for
optimal video quality. A loose cable connection can
lower video quality.
