We're getting no video signal out of an ASUS Crosshair IV Formula with various graphics cards. There is no onboard graphics unfortunately.

Situation (darkest Africa) dictates that we only have a VGA monitor (which works) so we have tried DV-I to VGA and HDMI to VGI adapters from all ports of both graphics cards.

Both cards are powered and their fans are spinning.

The motherboard does not beep or flash or indicate any other error.

We can connect to the motherboard with a ROG Connect cable and query temperatures, reset, switch off etc.

Tried resetting CMOS, swapping RAM, different power source and connectors to GPU, different PCI slots, no picture nothing.

One pin on the DVI to VGA connector was bent and shorted to another but we bent it back.

PSU is a GX1050W

What should we be checking?

Is there any software (possibly via ROG Cable) to diagnose issues?
