I have been having problems running two monitors for over a year now, and I can't understand what is going on. I have not seen this before and I need an answer before I lose my mind
To start, I am running a 2011 mac mini w/ amd 6630m. I bumped the ram to 8gb as soon as I got it. I ran it using one 24' 1920x1080 monitor from the start via HDMI. After a few months, I bought a 46" 1080p TV. I ran the TV through HDMI, and the monitor through mini-dvi using a converter (mini dvi>dvi). This ran without problems for months. Later I installed a 128gb ocz vertex 4, and had no problems for months.
One day, my monitor suddenly stopped detecting my monitor via dvi. I can't explain why. For the last 12+ months, the monitor will work on and off. I can be watching netflix at night on my 46" through HDMI, and out of nowhere, my 24" turns on, and is working fine again. I wake up the next morning, and can't detect my monitor again. I cannot explain the randomness in which it will detect the monitor. Nothing I do in particular causes it to turn on or off, and it often happens when not even using the computer.
I am wondering if my use of a 3tb external drive via usb could be the problem. Sometimes even opening system preferences, I get a few seconds of lag while the HDD starts up. I have OSX on my vertex 4, so it seems strange.
Has anyone experienced anything like this? I am starting to think i need to reinstall the whole OS, but I have always worried about doing so. I have also thought it could be the mini dvi cord, but it doesn't seem like moving the cord or re-plugging it in causes any change.
Sorry for the lengthy read, but this is something I have never seen before, and can't explain what is going on. Any advice would be greatly appreciated!
