Hello, We are trying to hook up our TV as a secondary monitor (for hulu, netflix, etc) but it defaults as the primary monitor. We would like to keep the iMac as the primary monitor, and have the TV as a secondary, but cannot figure out how to do it! The only way we can get the imac back to primary status is if we use mirror mode. Once we take it off mirror mode, the TV becomes the primary monitor again, and there appears to be no way of switching it in OSX display preferences. I've done similar hookups with my laptop, and the TV defaults as the secondary monitor. Why isn't this happening with our iMac? Any ideas? Thank you very much for your help!
