Graphics Subsystem
The graphics subsystems main interfaces like DisplayPort and DVI are part of the processor. Only
a few sideband signals (DDC channel, hot plug detection) are located within the PCH CM238.
The PC7-FESTIVAL offers two DisplayPort interfaces with latching receptacle in the front panel.
The latching feature prevents DisplayPort cables from detaching in vibrating or harsh
environments.
When alternate display interfaces like DVI-I or VGA are required, a variety of converters are
available in active or passive form, as adapters or cables.
Independent from the video standard actually in use, DisplayPort, DVI-I or VGA, the VESA DDC
standard is supported. This allows to read out important parameters, e.g. the maximum allowable
resolution, from the attached monitor. DDC power, +3.3V on DisplayPort connectors, is delivered
via electronic switches to protect the board from an external short-circuit condition (1.5A) and to
prevent back current flows.
Due to the popular Intel CPU are graphics drivers incorporated within any common operating
system.
