Mac Pro :: No Signal From Mini DisplayPortMay 29, 2012
I just recieved my Mini DP to DVI adapter so that I can use my second 23" Apple display.† I just upgraded to ATI Radeon HD 5770 so now I have 1 DVI and 2 mini DP.† I want to run 1 display off of the DVI and 1 off of the Mini DP. Both displays work with the DVI port but neither of them work on the Mini DP with the adapter.†
I know that I need to upgrade to Snow Leopard for the ATI Radeon HD 5770 to fully function.† I am waiting for the upgrade to arrive in the mail. Do I need to be running Snow Leopard for the Mini DisplayPorts to work at all or is there something I can fix before the upgrade?
