Sabertooth z77: no signal from HDMI if graphic card is plugged

post #1 of 4
Thread Starter 
Hello there,
recently I bought an Asus Z77 Sabertooth.

I installed my GTX 560 on it, and I'm experiencing a problem. My primary monitor is linked with the graphic card with the DVI plug, and works fine. If I try to connect my 2nd monitor with the motherboard HDMI output, the 2nd monitor isn't recognized at all.

I also tried to unplug the GTX and just use the HDMI output port, to check if it's broken or something. It is not, without the GTX onboard it works correctly.

Is there anything I can do?

I'd imagine your board is disabling onboard graphics when it recognizes a dedicated graphics... I'd probably look in the BIOS for an option like that.

But that's not the case because the Nvidia card loads fine, with it's drivers and everything. This is driving me nuts. :_(

Exactly, when you have a dedicated card in it works fine on the card but not on the dedicated mobo outputs? Yes?
