I have a late Mac Mini 2012, 2.5 GHz Intel Core i5, 16gb RAM. I currently am using the HDMI and and the display port with HDMI adapter and then HDMI into the two Lenovo 23" monitors. I made the mistake of buying directional HDMI cables from AMAZON (mono price) and sometimes when I reboot my monitors clink off and on for a while before booting up. I think its due to the directional HDMI cables. Has anyone else had this issue? Can anyone recommend some slim HDMI cables that you are happy with on a dual monitor/mac-mini setup?
