2.5.2 DVMT 5.0 support
DVMT (Dynamic Video Memory Technology driven by OS driver) 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. Up to 352 MB of system memory can be
allocated to DVMT on systems that have 512 MB 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.
2.5.3 ADD2 card support
The KTQ45 board routes two multiplexed SDVO ports that are each capable of driving up to a 200 MHz
pixel clock to the PCI Express x16 connector. The SDVO ports can be paired for a dual channel
configuration to support up to a 400 MHz pixel clock. When an ADD2 (Advanced Digital Display) card is
detected, the Intel GMA 4500 graphics controller is enabled and the PCI Express x16 connector is
configured for SDVO mode. SDVO mode enables the SDVO ports to be accessed by the ADD2 card. An
ADD2 card can either be configured to support simultaneous display with the primary VGA display or can be
configured to support dual independent display as an extended desktop configuration with different colour
depths and resolutions.
ADD2 cards can be designed to support the following configurations:
•
TV-Out (composite video)
•
TMDS for DVI 1.0
•
LVDS
•
Single device operating in dual channel mode
•
VGA output
•
HDTV output
•
HDMI support (when used with the HD Audio Link)

2.5.4 PCIe Passive Graphic card support
The KTQ45 board routes two TMDS ports that are each capable of driving up to a 200 MHz pixel clock to the
PCI Express x16 connector. When a TMDS card is detected, the Intel GMA 4500 graphics controller is
enabled and the PCI Express x16 connector is configured for TMDS mode. A TMDS card can either be
configured to support simultaneous display with the primary VGA display or can be configured to support
dual independent display as an extended desktop configuration with different colour depths and resolutions.
PCIe Passive Graphic cards can be designed to support the following configurations:
•
TMDS for DVI 1.0
•
Display Port
•
HDMI support
