3.4 Display connector
The KTQ45 board family provides onboard Analogue CRT interface. Additionally the KTQ45 boards provides
support for ADD2 cards through the onboard PCI Express x16 connector, with extension capability for
support of DVI, LVDS, VGA, HDMI/UDI, TV-Out, etc.
If a PCI Express x16 Graphics add-in card is used, the onboard Graphics controller (GMA 4500) is disabled.
