However, there was one very disappointed issue: the presentation view on project screen was not in full screen mode. During the break, several people from audience want to the front to offer help. I was there. I thought I could help, but I have never used PPT for Mac before. My initial thought was the settings in the projector. But it was find when I changed to desktop and there was no problem to present a pdf file in full screen mode. However, I could not figure it out. Since the time was short, Marco told us to give it up and restore it back the its original status. I told Marco that he should get his PPT file in PDF instead of PPT for Mac app.
After I got back home, the issue is still in my mind. I googled this issue and found some information about it (I don't have PPT so I cannot test it out).
One thing I did not gave it a try is to use Mac's zoom feature for the screen. In many of WWDC shows, Apple presenters uses the zoom feature (control+scroll up) to enlarge a portion of screen. The interface of PPT is too crowded. The ribbon area take too much spaces, which makes the slide show too small. May be there is a way to disable ribbon show and to make the window cleaner.
The following are some information I found from web:
- This forum discussion looks like the same issue as we had today. There two toolbar buttons in ribbon: Presenter View and Mirror Show. It looks like PPT uses 2 screens for presentation.
- Apple support communities forum has one topic about similar issue. A solution is about to configure screen from Apple system preferences: Displays.
