Processor Graphics Subsystem
The Intel® Compute Card supports graphics through Intel® HD Graphics.
1.9.1
Integrated Graphics
The Intel® Compute Card supports integrated graphics via the processor. Two Digital Display
Interface (DDI) lanes are available from the Compute Card connector. How the DDI lanes are used
is dependent on the device the Compute Card is plugged into and how the lanes are configured.
By default, the DDI lanes are configured as DisplayPort* 1.2. The DDI lane from the extended part
of the connector can be configured as HDMI* 1.4b via DDI_Config.
High-Bandwidth Digital Content Protection support for content protection
o
HDCP 2.2 supported via DisplayPort
o
HDCP 1.4 supported via HDMI
Resolutions and refresh rates supported

Video Memory Allocation
Intel
®
Dynamic Video Memory Technology (DVMT) is a method for dynamically allocating system
memory for use as graphics memory to balance 2D/3D graphics and system performance. If your
computer is configured to use DVMT, graphics memory is allocated based on system
requirements and application demands (up to the configured maximum amount). When memory
is no longer needed by an application, the dynamically allocated portion of memory is returned to
the operating system for other uses.
