3.5 KTUS15 Graphics Subsystem
The KTUS15 boards use the Intel ® US15W chipset for graphical control by the embedded Intel® Graphics
Media Accelerator 500.
The Intel Graphics Media Adapter includes LVDS and Serial DVO display ports permitting simultaneous
independent operation of two displays.
If more independent displays are required then PCI Graphic Card can be added.
Using PEG (PCI Express Graphics) card will make the internal graphics device, LVDS and SDVO ports not
function.
The KTUS15 board supports a Low-Voltage Differential Signaling interface that allows the Intel Graphics
Media Adapter to communicate directly to an on-board flat-panel display. The LVDS interface supports pixel
color depths of 18 and 24 bits, one-pixel per clock displays.
The Intel ® US15W chipset Serial DVO port either connects to a Serial DVO Digital DVI (DVI-D) or a
Serial DVO Analogue DVI (DVI-A) controller depending on the board configuration (refer to KTUS15/mITX
Board configurations section).
