3.1.3 Display Emulation
Display emulation is supported using the HDMI ports so that the system may be remotely accessed
in a headless configuration or be capable of tolerating display connectivity interruptions without
the operating system redetecting and rearranging the overall display layout. The display emulation
feature may be enabled in BIOS Setup with the following checkboxes:
“Virtual display emulation”: provides a 1280x1024 virtual display when no displays
are connected to the system and provides an additional 1280x1024 virtual display if
one display is attached to the system. If two displays are attached to the HDMI
ports these displays will be enabled and no virtual displays will be provided.
“Persistent display emulation”: emulates that both displays are always connected
to the system no matter their actual connection status. The EDID information from
each display will remain programmed through S3, S4, S5 and G3 power states until
the feature is disabled.
When “Persistent display emulation” is enabled another drop-down menu
(“Inconsistent Display Device”) will become visible that allows the user to
select the behavior of the system when the display device EDID is
inconsistent with the EDID stored by the system.
“Block boot” (default selection): the BIOS will display a warning
message with options and will wait indefinitely for a user selection.
“Countdown”: the BIOS will display a warning message with options
and will wait 10 seconds before booting.
NOTE
When using “Persistent display emulation” it would be expected behavior for the system not to
properly drive displays different than those connected when the feature was enabled, as the EDID
parameters of the initially connected displays are still being driven by the system. In order to retrain
the system for different displays, the persistent display emulation feature must be disabled in the
BIOS, the system rebooted, and then the persistent display emulation feature must be reenabled.
