TIP: Autodetecting New Display Hardware
If you change your display hardware after installation, use sax2 -r on the
command line to cause SaX2 to detect your hardware. You must be root to
run SaX2 from the command line.
Graphics Card
It is not possible to change the graphics card because only known models are supported
and these are detected automatically. However, you can change many options that affect
the behavior of the card. Normally, this should not be necessary because the system
already has set them up appropriately during installation. If you are an expert and want
to tweak some of the options, click Options next to the graphics card and select the
option to change. To assign a value needed to a certain option, enter this value in the
dialog that appears after selecting that option. Click OK to close the options dialog.
Monitor
To change the current settings for the monitor, click Change next to the monitor. A
new dialog opens in which to adjust various monitor-specific settings. This dialog has
several tabs for various aspects of monitor operation. Select the first tab to manually
select the vendor and model of the display device in two lists. If your monitor is not
listed, you can choose one of the VESA or LCD modes that suit your needs or, if you
have a vendor driver disk or CD, click Utility Disk and follow the instructions on the
screen to use it. Check Activate DPMS to use display power management signaling.
Display Size, with the geometrical properties of the monitor, and Sync Frequencies,
with the ranges for the horizontal and vertical sync frequencies of your monitor, are
normally set up correctly by the system, but you can modify these values manually.
After making all adjustments, click OK to close this dialog.
WARNING: Changing Monitor Frequencies
Although there are safety mechanisms, you should still be very careful when
changing the allowed monitor frequencies manually. Incorrect values might
destroy your monitor. You should always refer to the monitor's manual before
changing frequencies.
