I originally started with a USB Powered active adapter. After ati officially started supporting adapters all of a sudden my powered one started having issues. I switched it with the "Officially" supported HIS Mini DisplayPort to Single Link-DVI Eyefinity Adapter and havent had a single issue since. Look on the egg for item #N82E16814999033
