Warning: It is not recommended to use any PCIe Riser card in combination with PCIe
Graphics card. Such combination does not comply with PCI Express 2.0 standard with the risk
of generating instability.

2.5 KTQ45 Graphics Subsystem
The KTQ45 boards use the Intel Q45 chipset for the graphical control. This chipset contains two separate,
mutually exclusive graphics options. Either the GMA 4500 graphics controller (contained within the AC82Q45
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 4500 graphics controller is disabled.
2.5.1 Intel® GMA 4500
Features of the Intel GMA (Graphic Media Accelerator) 4500 graphics controller includes:
• High quality graphics engine supporting
o DX10* and OpenGL* 2.0 compliant
o Core frequency of 400 MHz
o 1.6 GP/s pixel rate
o High-Quality 3D Setup and Render Engine
o High-Quality Texture Engine
o 3D Graphics Rendering Enhancements
o 2D Graphics
o Video Overlay
o Multiple Overlay Functionality
• Analogue Display (CRT)
o 350 MHz Integrated 24-bit RAMDAC
o Up to 2048x1536 @ 75 Hz refresh
o Hardware Colour Cursor Support
o DDC2B Compliant Interface
• Multiplexed PCIe x16, SDVO and TMDS.
o PCIe x16 supports also PCIe Graphics card. Using PCIe Graphics card in combination with
onboard graphics (VGA) is possible if BIOS setting Initial Graphics Adaptor = IGD. In this
case onboard 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 (Serial Digital Video Out) ports (2 channels single mode) for additional ADD2
(Advanced Digital Display 2) cards supporting second CRT monitor or Dual LVDS (Low
Voltage Differential Signalling) panels or DVI (Digital Visual Interface) panels.
o TMDS (Transition Minimized Differential Signalling) (2 channels) for additional, HDMI (High-
Definition Multimedia Interface) support with 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.
o 200 MHz dot clock on each 12-bit interface
o Dual independent display options with digital display
• Dynamic Video Memory Technology (DVMT 5.0) support up to 352 MB
