Help! Need to know the best DP to DVI adapter to drive six 27”  1980/1080 monitors - this computer is for data stream only no gaming - bought regular DP to DVI adapters they will not send a signal – looks like I need active adapters. Found Accell Ultra Mini  Display Port to DVI-D Single Link Adapter is this the right active adapter.  Also the two DP to DVI’s that came in the box are they active adapters? thanks
