Recently changed to a new monitor (LG 34 inch). This is the first monitor I'm feeding over displayport on an Asrock Z68 Pro 3 motherboard with Intel HD 3000 graphics. (prior doual monitors were fed over hdmi and dvi).

When I boot the system from being off, the monitor won't display anything and says "out of range." If I then put the system into standby, then wake it up, the monitor will come to life.

Have tried to change the refresh rate from 60hz to 30hz and it does the same thing. Any ideas of something else to try?

Also, are there difficulties getting bios to display when fed over DP or into a super high res monitor? It doesn't display anything on boot.

Thanks for your guidance. Sean
