I've been using my MacbookAir 11inch (2011) for school exclusively, pretty mild use over the years (I use my desktop at home). Last week I could no longer connect to my external BenQ display I sometimes use when I need more display width. Same on book camp. Visited the apple store now, same on their displays. They told me I'd need a new motherboard, would cost over €500 Any idea if there could be some quick dirty fix? I've never heard of someone's displayport to stop working honestly. Some bad luck.
