Video Setup - IBM Aptiva Hardware Handbook

Parallel Port. This option lets you change the parallel
port address. Your computer has one parallel port with a
special address (identifying location). If you add adapter
cards to your computer that have additional parallel
ports, you must make sure that each parallel port has a
different address assigned to it.
If you change parallel ports on the Devices and I/O Ports
screen, you may also need to make changes to your
software. For instructions on changing your software,
see the user's guide or online information that came
with your software.
Parallel Port Mode. This option lets you choose either
the Standard or Extended mode for a parallel port. You
can increase the efficiency of your parallel port by using
Extended modes with supporting hardware.
If you change the mode of a parallel port, you may need
to make changes to the supported hardware and its
software.
Parallel Port Extended Mode. This option is only
available when you choose Extended as the parallel port
mode. The Extended modes use recent technology and
are only supported by newer hardware (such as a
printer). The available Extended modes are:
•
Bidirectional: This mode is used for data transfer to
other PC systems and supported devices.
•
EPP: The Enhanced Parallel Port (EPP) mode is a
high performance bidirectional mode.
EPP modes are not available when the Parallel
note:
Port address is set to 3BC.
•
ECP: The Extended Capabilities Port mode (ECP)
provides higher speed data transfers than the
Compatible mode. It is used for high-speed printers
and other devices.
•
EPP and ECP: This mode combines the capabilities
of the ECP and EPP modes.
Mouse. This option allows you to enable or disable the
mouse.
Diskette Drive (A: or B:). This option shows you an
entry for each diskette drive on your computer. If you
add or change a diskette drive, you must select the
correct diskette drive type on the Devices and I/O Ports
screen.

Video Setup

Choosing the Video Setup option on the Devices and I/O
Ports screen displays the Video Setup screen. The Video
Setup screen shows the amount of video memory
installed on your computer and allows you to change
your monitor's refresh rates. The refresh rate is the rate
in hertz (Hz) at which the entire image is drawn on the
screen.
You should change the refresh rates only if you attach a
monitor to your computer that is different from the
monitor that came with your computer. The options you
can choose to change the monitor's refresh rates are
Video Display Type, Monitor Horizontal Frequency, and
Refresh Rate.
Super VGA (SVGA) and multifrequency monitors
can refresh the screen faster than other types of
note:
monitors. You must make sure the refresh rate is
set correctly for your monitor.
