Hi all. The Mac Pro people seem to have trouble with their computers hooked up to monitors using a MiniDisplayPort to DisplayPort connection. There might be issues both with cables and adapters: http://forums.macrumors.com/showthread.php?t=1011799 http://forums.macrumors.com/showthread.php?t=1017977 I'm trying to figure out if it's a problem specific to the Mac Pro video card or if it's a general issue that affects MacBook Air users as well. If you're connecting your MacBook Air to a monitor using a MiniDisplayPort to DisplayPort connection, could you please post which adapter+cable or cable (brands, links if possible) you are using with which monitor? Thanks!
