Here is a similar discussion: I have put some of my problems up there as well. Hi everybody The MacBook Pro folks have the same issues. I also tried the Intel Graphics control panel in Windows which kept telling me that I didn't have an external monitor connected.There would seem to be a problem with the Windows driver for the Thunderbolt port. I tried a number of projectors under Win 7 OS without any sign of life. That would pretty much eliminate any hardware issues. I have tried the VGA adapter under the Lion OS to project a Keynote slide show - works like a dream. Looks like we're all having the same issue of getting a VGA adapter to work when ruuning from a Win 7 partition.
Optoma ep721 projector adapter cable for macbook air for mac#
Any ideas what I could try? Optoma Projector Driver For Mac The graphics card driver seems to be the newest available. Manually setting resolution as well as using Win plus P shortcut did not help. Connecting the adapter before/after beamer was ready did not help. Putting the baby to sleep and waking up did not help. The third did everything automatically with the correct resolution. 2 out of 3 projectors tested refused to recognize the signal from the Macbook. Booting into Windows 7 (Bootcamp installation) gives different issues. This can then be adjusted manually and works. However, sometimes the Macbook would not recognize the beamer resolution and switch to 648x480. I got the adapter to VGA and everything seems to work fine most of the times when booting MacOS Lion. Hi everybody I am having some issues with the new Macbook air (mid-2011) and connecting a data projector. Although it has the same lumens spec as the “BenQ projectors,” the Epson can obtain brighter.
