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 4500MHD 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 4500MHD graphics controller is disabled.
Dual independent pipe support, Mirror and Dual independent display support.
Dual Display support with combinations of SDVO/TMDS (Serial Digital Video Out/Transition Minimized
Differential Signalling) port devices and on-board CRT/LVDS (Low Voltage Differential Signalling).
2.5.1 Intel® GMA 4500MHD
Features of the Intel GMA (Graphic Media Accelerator) 4500MHD graphics controller includes:
•
High quality graphics engine supporting
o
DirectX10 and OpenGL 2.1 compliant
o
Shader Model 4.0 support
o
Intel ® Clear Video Technology
o
Core frequency of 533 MHz
o
Memory Bandwidth up to 17GB/s
o
10 Execution Units
o
1.6 GP/s and 2.7 GP/S pixel rate (DP output)
o
Hardware Acceleration full MPEG2, full VC-1 and full AVC
o
Full 1080p HD Video playback inclusive Blu-ray
o
Multiple Overlay Functionality
o

SPWG (VESA) colour coding. OpenLDI (JEIDA) colour coding is 18 bit with or without Dithering.
Note that on-board LVDS port is disabled if ADD2-LVDS card is used.
•
(TV-out connector not mounted, Component, S-Video and Composite interfaces, NTSC/PAL and
HDTV Graphics mode. 10-bit DAC. Macrovision not supported).
•
Multiplexed PCIe x16, SDVO and TMDS.
o
PCIe x16 (PCI Express 2.0) supports also PCIe Graphics card. Using PCIe Graphics card in
combination with on-board graphics (VGA or LVDS) is possible if BIOS (from version
KTGM4506) setting
Boots Graphic Adaptor Priority = IGD
. In this case on-board graphic will
be Primary desktop and PCIe Graphics will be extended desktop. Note that PCIe Graphics
driver shall be installed before the Intel Graphics driver.
o
SDVO ports (2 channels) for additional ADD2 (Advanced Digital Display 2) cards supporting
second CRT monitor, LVDS or DVI (Digital Visual Interface) panel(s).
o
TMDS

HDCP (High-bandwidth Digital Content Protection) and HD Audio, DVI support, or DP
(DisplayPort) support with 8/10 bit colours in WQXGA (2560x1600 pixels) and HDCP.
o
DVI, HDMI and DP support Hot-Plug.
