Not sure what the problem is. I have two Mars 760's on my Maximus V-E and the main card is connected to the monitor through the miniDP. There's no signal when I boot from off state. I have to reboot to activate the port. This doesn't happen when using the DVI ports. I'd like to use the DP cable because my DVI cable is bulky and short. Should I just return the cards or is there something that can be done?
