Question: MacBook air and projector connection.
I am having some issues with the new Macbook air (mid-2011) and connecting a data projector. I got the adapter to VGA and everything seems to work fine most of the times when booting MacOS Lion. However, sometimes the Macbook would not recognize the beamer resolution and switch to 648x480. This can then be adjusted manually and works.
Booting into Windows 7 (Bootcamp installation) gives different issues. 2 out of 3 projectors tested refused to recognize the signal from the Macbook. The third did everything automatically with the correct resolution. Putting the baby to sleep and waking up did not help. Connecting the adapter before/after beamer was ready did not help. Manually setting resolution as well as using Win plus P shortcut did not help. The graphics card driver seems to be the newest available.
Any ideas what I could try?
MacBook Air, Mac OS X (10.7)
