2.5 KTGM45 Graphics Subsystem
The KTGM45 use the Intel GM45 chipset for the graphical control. This chipset contains two separate,
mutually exclusive graphics options. Either the Intel® GMA X4500HD graphics engine (contained within the
GM45 GMCH) is used, or a PCI Express x16 add-in card can be used. When a PCI Expressx16 add-in card
is installed, the GMA X4500HD graphics controller is disabled.
Dual independent pipe support, Mirror and Dual independent display support
Dual Display support with combinations of SDVO/TMDS port devices and onboard CRT/LVDS/TV

2.5.2 DVMT 5.0 support
DVMT (Dynamic Video Memory Technology) enables enhanced graphics and memory performance through
highly efficient memory utilization. DVMT ensures the most efficient use of available system memory for
maximum 2-D/3-D graphics performance. More than 512 MB of system memory can be allocated to DVMT
on systems that have 1GB or more of total system memory installed. DVMT returns system memory back to
the operating system when the additional system memory is no longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup) for
compatibility with legacy applications. An example of this would be when using VGA graphics under DOS.
Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics
buffer as needed for performing graphics functions.
Note
: The use of DVMT requires driver support by the operating system.
