I'm using ADV7441ABSTZ-5P to interface with DVI-D single link input. Since VGA input is not used, can the VGA input pins such as HSYNC, VSYNC be left unconnected? Or should they be connected to VCC or GND? Can I float FB (pin 74), VS_IN (pin 62), HS_IN (pin62), HS (pin 17), and VS (pin 18)? If not, can you advise their terminations?
