Hi, just bought a Macbook Air recently (2010 edition) and at the same time I bought a mini displayport-HDMI adapter and have been using that to display things on both an external screen and movies on my TV- similar to this: http://cgi.ebay.com/Mini-DisplayPor...292?pt=LH_DefaultDomain_0&hash=item27b9d5e8e4 Now the other day, I took out the converter from the mini displayport on my mac while I could see my mac homescreen picture on my TV, and after putting it back it seems it cannot connect any more to either TV or external monitors. When I insert the above converter the screen on my MBA turns blue for a second, just at it used to once it detected an external screen, but then nothing happens??? I am very new to the mac world, but can I accidently have turned some setting off or any clues on how to determine what is wrong here? Unfortunately I dont knwo anyone with a mac I could just try my cable with. Thanks in advance!
