I have an Acer TC-780-ACKI3 PC I want to hook it up to a Acer S271HL Monitor using a HDMI cable but when I do I get a Black screen saying "Input not Supported" !  I thought the Problem was the Monitor but when I hook it up to another PC using the same cable it worked fine and I got the desktop! The problem lies in the Acer PC, something needs to be reset in the PC but I have no idea what ! Has anybody had this problem, any and all help would be appreciated !
