So I just hooked up a new Dell u2713hm to my 2011 Mac mini Server 2 days ago via the StarTech 6-Feet Mini DisplayPort to DisplayPort Adapter Cable - M/M (MDP2DPMM6) that I purchased from Amazon. Today the monitor is giving random black screen every few minutes or so. Anyone know what I can do to address this issue? Also, any other advice on how best to use this monitor with a 2011 Mac mini would be appreciated. Thanks!
