Intel® NUC Pro Chassis Element Product Specification

2.6 Display Emulation

The Intel® NUC Pro Chassis Element supports emulation of displays 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 Intel® NUC Compute

Element BIOS Setup (Advanced → Video → “Display Emulation” drop down menu) with the

following options:

• “No display emulation” (default selection): the system operates normally.

• “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 display are attached to the system 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, and S5 power states until the feature is disabled

or a power cycle event (G3 global state) occurs.

• When “Persistent display emulation” is enabled another drop-down menu

(“Inconsistent Display Warning”) 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

“Persistent display emulation” is not compatible with HDCP 2.2 displays.

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. A power cycle

(AC power loss) is required to retrain the system with a different display configuration.
