12. Graphic Interfaces
12.1 Video Controller
The coolMONSTER/PM uses the graphics accelerator integrated in
the Intel® 855GM/GME chipset, which delivers high-performance
2D,
3D
and
video
capabilities.
(Unified Memory Architecture) up to 32MB of system memory are
used as video memory.
The controller can drive four interfaces with its two graphic
engines on the coolMONSTER/PM:
†
Cathode Ray Tube (CRT) interface
†
Low Voltage Differential Signaling (LVDS) interface
†
2 Digital Video Output (DVO) ports
12.2 CRT Connector
The CRT (Cathode Ray Tube) interface is available through a
standard
DSUB15
connector
X9,
which
connector.
The following table shows the pin-out of the CRT connector.
