Hello all. I just got a displayport to HDMI adapter for the MBA. Here is the link to the one on ebay I bought. http://www.ebay.com/itm/310407826582?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 I got the first one home and could not get it to work at all. I contacted the seller and he replied that I might have gotten a bad one and he just sent me another one (kudos to the seller). Well, this one didn't work either. I'm wondering if the Thunderbolt port is bad or if there is some setting somewhere. Any thoughts? Thanks.
