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. With its interface to UMA (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
