Serial CPU Board
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 SC4-CONCERTO offers two DisplayPort interfaces with latching receptacle in the front panel. The
latching feature prevents DisplayPort cables from detaching in vibrating or harsh environments.
A 3
rd
DisplayPort is fed to the on-board connector P-HSE2. EKF expansion boards like S40-NVME
feature the possibility to gain access to the 3
rd
DisplayPort interface via Type-C receptacle.
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.
Graphics drivers can be downloaded from the Intel web site.
