FAQ and Troubleshooting Projection with UP
The projector flickers when I project UP and doesn't when I project normal PowerPoint or the like.
With some older projectors we have occasionally seen a "flicker" problem -- sometimes it seems like lines
are flickering in the display. This can be resolved by getting a "line booster". Most AV or media services
departments have them -- sometimes Mac users need them. Or ask to be moved to a room with a newer projector.
The screen rotates to portrait view when I flip the Tablet down -- and so does the projection!
This issue varies with each Tablet and we may not know the exact solution for your Tablet -- but rest assured -- there IS a solution. You may simply be able to rotate the screen correctly and have the projection work (use either your
built in Tablet screen rotation button, (in XP) control panel Tablet and Pen Settings, or (in Vista) right click on the background and click or unclick rotation in Graphical Properties. Another option is to rotate the screen BEFORE you connect to the projector.
I want to be able to switch to other applications and demo them. How do I do this?
You have options.
- You can turn off the second monitor mode and "re-connect" to the projector
using the usual method (Fn-F5 or whatever your machine uses). This can take some time if you don't use
your Tablet brand specific method for switching between monitor modes. Additionally some brands have
been known to freeze (requiring a re-boot) in multiple usages of these. Test yours out.
- You can put your other apps "on" the second monitor (I do it before class begins) and minimize presenter
to allow them to be "viewed".
- Be default, you can't control things on the second monitor with the Tablet pen (there's no way to "point"
there). So you will need to flip your Tablet up and use the keyboard/mouse to control these. Also, if you are in a
large classroom, you may have to loop behind you (awkwardly) to view the applications on the projected screen.
- Recommended The new application
Extended Desktop for Tablet PCs (a Microsoft PowerToy for Windows XP Tablet edition) can be downloaded for free
to solve this problem.
This puts up a window on your primary display (which you can control with the Tablet pen) and anything you drag onto
it is shown on the secondary display (the projected screen). You can select whether it displays that application
for you on your primary display or not. There is some scaling issue, since you can have that "window" sized
smaller on your primary display, but it displays full screen on the extended one. I found I just had to play for a
few minutes to get the trick.
