I recently started having a problem with my monitor going black and the message "#2 analog input" shows up. I was advised to replace my adaptor (I am using a mac mini) so I did... I replaced my monitor because I suspected my monitor was going bad, got a new monitor and now the problem is constant, can't keep a screen for more than a couple of minutes, Sometimes shutdown/restart gives me a screen for a bit, but once it starts, I am toast for the day usually. Do I need a video card as Applecare suggests? I hate to do it and then find out it isn't that, and I have not found anything online to confirm that. Thoughts anyone?
