i have an asrock motherboard 880gm-le that has an onboard hd 4250 that has supposedly advertised 2560x1600 dual-dvi support but i am only getting 1280x800. i used a older computer with 8600gt graphics card that works in that mode.
i did verify my monitor and dual link cable is working with another dual-dvi computer compatible computer getting 2560x1600 resolution. I have all the latest drivers installed. i wonder if this integrated graphics chip is capable of outputting dual link resolution at all. has anyone with this motherboard amd 880g ever gotten 2560x1600 to work?
guys, my issue has been resolved!!!
i was able to self-diagnose the problem.
the answer to this problem in case anyone ever has this problem.
if you have an AMI BIOS, you have to disable the HDMI audio under the advanced chipset configuration.
and now i have native resolution on my 30" monitor!
