Wireless Presentations from Tablet PC to the Big Screen

I do presentations and need to connect to a projector.

Rotation Confusion

When you rotate the screen to switch from laptop mode to slate mode, the image that is sent to the VGA port on the back of the machine inverts. The image on the projector comes out upside down.

My pet peeve about this is that if you want to work in slate mode for doing sketches during a presentation (I do this all the time), you have to turn the machine around so you are still in primary landscape mode. This puts all the connectors facing you. The alternative is to invert the image on the projector.

The real issue for me is that I often switch back and forth from laptop to slate mode several times in the course of a presentation so changing the settings on the projector is difficult to do on the fly.

Solution?

If you have access to two machines you can use one as a "viewer" for products like MaxiVista or VNC (or one of its many variants). I have successfully used UltraVNC.

You connect over a network connection so that this viewer mirrors what is on the Tablet PC.

Connect the projector to the viewer machine and you are off and running, literally. I use a wireless connection between the Tablet PC and the viewing machine, so I can wander about while doing the presentation.

And here is how I do it with MaxiVista

If you have access to a wireless network, you don't need the wireless router shown in the pictures above. There is a minor wrinkle. With MaxiVista, both computers must be on the same subnet. This is not a restriction with VNC.

I prefer MaxiVista because I find it more stable and because it does double duty for me when I want to work in desktop mode, back at the office. Then I use MaxiVista to control one or more of my Tablet PCs acting as virtual monitors. But that's a whole other discussion, and you would do well to go to the MaxiVista site for more information about that.

None of this discussion precludes using a true Wireless Presentation Gateway or a Projector that has built in support for video over 802.11x wireless. It just turns out that I can do what I have described above without any major capital outlay.

If I were in a position to buy new gear today, I would probably investigate some of the newer technology (previous paragraph). But for a relatively portable ad hoc solution, what I have been doing has worked well.
