5 IO-Area Connectors
5.1 Display connectors (IO Area)
The KTQ77 family provides one on-board Analogue VGA port, two on-board DP’s (DisplayPort) and
optionally one on-board LVDS panel interface. Two graphic pipes are supported; meaning that up to two
independent displays can be implemented using any two of the above mentioned graphic ports.
