Let me first explain my problem. I have a mac mini and I used to hook it up to my TV using Apple's Mini display port to VGA adapter. After a few months it quit working. I assumed at that time that it was just the adapter that was bad. I had an HDMI to VGA adapter laying around and so I have just been using that ever since. I have no thunderbolt devices and so I never noticed anything wrong. Last week I bought a second monitor to use with my mac. I broke out the old adapter (That I thought was broken) and it didn't work, no surprise there. So I then went to amazon.com and bought a cord that is mini display port on one end and VGA on the other. I plugged this into my mac and to my surprise IT DID NOT WORK. I thought what the hell don't tell me this cable is no good. (The brand is cable matters and I have gotten some pretty decent stuff from them before). So I went and got my Dell laptop which has a mini display port. It works just fine with that. So...now I am thinking that it is actually my thunderbolt/ mini display port on my mac mini that is the issue. It is out of warranty (its the 2011 model). Does apple have a flat service fee for out of warranty problems? Any other ideas what could be wrong? Thanks for any help!
