- Auto (Default)—The external video connection to the embedded video controller is automatically disabled to save power when a monitor is not attached. It is enabled automatically when a monitor is attached (including when the server is operating).
- Always Disabled—The external video connection to the embedded video controller is disabled and a monitor connected to this port does not display except during system boot.
- Always Enabled (選這個)—The external video connection to the embedded video controller is always enabled. This option is only required if a monitor is attached with a monitor detection that does not function, causing Auto mode not to work properly.
