Configuring video adapters

Understanding multi-monitor configuration

SCO systems provide limited support for ``multi-monitor'' configuration, also known as ``multi-headed'' configuration. Multi-monitor support means you can display one graphical environment on two (or more) monitors, thus increasing your graphical work space.

To determine if your adapter will support multi-monitor configuration:

Ensure that your graphics adapters support multi-monitor configuration and have no hardware conflicts. They must not use the same I/O ports or base addresses. Your graphics adapter documentation may indicate if your adapter supports multi-monitor (or ``multi-headed'') configuration. Install each adapter individually to verify that the graphical environment functions properly.
Consult your adapter documentation to ensure that VGA can be disabled.

NOTE: UnixWare 7 systems support up to 32 monitors on one system, but for the purposes of this procedure we will assume the user is installing only two. You must complete the configuration process for each installed adapter, monitor, and resolution.

To set up a multi-monitor configuration:

Once you have verified that both adapters work, and you have ensured that there are no hardware conflicts, install the adapters in the system and proceed with multi-monitor configuration.
Install the monitors.
Configure the first adapter, using the normal procedure.
While configuring the second adapter, select Multi-monitor configuration -- specify function keys from the Function Key Setup window.
From the Specify Function Keys window, select the function key(s) that you want to control the multi-monitor environment.
Finish the normal configuration procedure for the second adapter.
After you finish configuring the last installed adapter, you must configure your graphical environment to use the added screens. See your graphical environment documentation for more information.

NOTE: If you configure a second video adapter in multi-monitor mode on some function keys and as the primary adapter on other function keys, configure the primary function keys first. If you configure the multi-monitor function keys first and then configure the remaining function keys for the primary video adapter, the multi-monitor configuration will be changed to be the primary adapter.
