I just got the ASRock Z87 Extreme4 and the onboard DVI does not work, no signal during POST, no signal in Windows, nada. My monitor is one of those Korean 27" IPS with only dual-link DVI, nothing else. Does this motherboard support my monitor even if I change the resolution to below the single-link DVI maximum of 1920 x 1200 @ 60 Hz? The onboard HDMI outputs to my HDTV with no problems.

Thanks.
