Motherboard: No Display Signal - GPU: Displays Fine but only DVI-I, I the need DVI-D on the mobo.

I've got a Z97pro Mobo and a GTX970 GPU. I'm trying to hook up a new monitor but I'm getting no output from the motherboards hdmi or DVI ports. The GPU displays fine from both the hdmi and dvi-i, but in order to get the 144hz out of my new monitor I need to use a dvi-d port, which only my mobo has. I know there's a setting in the bios, just not sure how to go about it, just need some specifics.

On another note, could I simply use my gpu's dvi-i port with my dvi-d cable? would that work for the 144hz?

I'm also curious, is there's any differince in function or quality when using the mobo display vs the gpu?

    Some boards will disable the iGPU ports when there's a gfx card populating the PCIe x16 slot. Check if that is the case with your board.

    The DVI-D and DVI-I should both produce the same digital signal. The only difference being the DVI-I (I=integrated) also contains pins for the analog signal needed for older VGA monitors.

    Thanks clutchc, in that case I'll just use the dvi on my gpu.

    UPDATE: yep, 144hz works perfect. The reason for all this was because I thought I had a bad dvi port on my gpu. When I first built my rig I was using a VGA to DVI adapter on an older monitor and was getting some bad atifacts, scanlines ect, but hdmi worked fine. I guess it was just the old adapter and vga cord not jiving with the 970s dvi port. Thanks again.
