Problem 1: I have 12 core 2.4, ATi 5770. I can not get the dual displays to work. I have a 30in ACD and 23in ACD. Tried running the Dual link to the 23in and the regular connector (from MiniDP) doesn't work. I also tried the 23in to the DVI which works. So the 23in is fine. Tried the 30in ACD to the MiniDP doesn't work. I do not no whats going on here, possible a bad video card? Problem 2: I installed a Caldigit usb3/esata card into the 5,1. If I leave the Esata G-drive hooked up to the computer during boot up, my keyboard does not work. Any help on these issues would be appreciated.
