CHAPTER 9: Troubleshooting
Type of connection used—You can connect the notebook
video output to a TV. However, the connection type has
an affect on the video quality. The notebook has two
video outputs:
•
HDMI—If your TV includes an HDMI port, connect the
HDMI cable from the notebook's HDMI Out port to the
TV's HDMI In port. HDMI display quality is usually
superior for TV images. HDMI also transmits audio to
your television. Many older TVs do not have an HDMI
port.
•
VGA—If your TV does not include and HDMI port, but
does include a VGA port, connect the VGA cable from
the notebook's VGA (monitor) port to the TV's VGA In
port. Many older TVs do not have a VGA port. VGA
only transmits video. You should use the built-in
speakers, a set of headphones or external powered
speakers, or connect your notebook to a stereo
system to hear sound.
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 Gateway.
Important
Cable connections must be made correctly for optimal video
quality. A poor cable connection can lower video quality.
Screen resolution—By default, the notebook uses a
screen resolution optimized for the LCD screen. Many
older TVs cannot display this high of a resolution and
may shift, scramble, or scroll the picture. For a better
picture on a TV display, you may need to lower the screen
resolution to 800 × 600 or 640 × 480. For more
information about changing the screen resolution, see
"Changing color depth and screen resolution" in your
online User Guide.
