●
If you have installed an operating system other than the factory-installed operating system, check to be
sure that it is supported on the system.
●
If the system has multiple video sources (embedded, PCI, or PCI-Express adapters) installed (embedded
video on some models only) and a single monitor, the monitor must be plugged into the monitor
connector on the source selected as the primary VGA adapter. During boot, the other monitor connectors
are disabled and if the monitor is connected into these ports, the monitor will not function. You can
select which source will be the default VGA source in Computer Setup.
