Issue using a second monitor
Just recently purchased a new LG LED cinema display to use as a second monitor. Unfortunately have a major issue in doing so. The monitor is not seeing a signal coming from my Mac Pro, which I believe is a late 2011 or early 2012 model. I have mini HDMI convertor which is then connected directly to the HDMI cable attached to the monitor.
My main monitor is the Apple display. Not sure what is going on but any help at this point is greatly appreciated.
