how to get HDMI to change resolutions

[jpottsx1]

Hi, I've built the CustoMac Mini 2011 using the Gigabyte GA-H67N-USB3-B3 logic board and the i5-2500k cpu.

When I plug in my hdmi cable in either port 1 or port 2 I only get 1028 x 768. I have installed the Macbook Pro 8,1 also. Am I supposed to install something else to get the video to work properly.

Well I finally got it to work;

Upgrade BIOS to F7 with HDMI Audio
Install DSDT from database
locate and change the "Device (IGD0) with the following code from pippox0 in the post http://www.tonymacx86.com/viewtopic.php?f=15&t=36335

THX a bunch
