How to override a Projector control out of synch with the Classroom projector
2011/12/10
Leave a comment
- When the projector control system is “out of synch”with the projector.
- Symptom: “System off” does not turn the projector off, but also “System on” does not turn.
- Workaround: From the control panel Home screen, access soft button “system tools”
- Here you can manually turn the projector on/off (and the close the screens)

Screencasts for Fall 2011 Workshop: Computer classroom management in the LRC using Sanako Study 1200

- The workshop stayed “this side of the digital audio lab”, i.e. focused on those generic teaching tasks that the Sanako Study 1200 can facilitate which have the widest teaching application (including in, but also beyond language-skill-courses):
- remote controlling student computers,
- screen sharing, collaborating with students,
- launching applications on students computers,
- sending students to webpages,
- launching handout files to students and collecting their input back
- locking their computers, screens or keyboards,
- “clicker” classroom polls, for which I have written a PowerPoint Template you can base your own clicker-like face-to-face class exercises on.
- and more…
- Here are two screencasts of my presentation:
- one for the right screen/participant screen (using the Study1200 teacher to student screen casting). Requires Windows Media Player on PC, like in the LRC: download from MS-SkyDrive.
- one for the left screen/projector, where I displayed mostly a PowerPoint. You can watch this in parallel using another player, e.g. the VLC player, like in the LRC. However, it can also stream from MS-SkyDrive.

PowerPoint 2010 upgrade from 2007 disables setup show display on secondary screen
2011/12/06

- Symptom: Without hardware changes (a visualizer that seemed to enter into the equation as an AV source seems to have been ruled out as culprit), PowerPoint cannot display show from primary right screen to secondary left screen.
- Cause: Upgrade to PowerPoint 2010 from 2007, but seems really an underlying video driver limitation that has given us grieve in our – admittedly uncommon: 1024*768 on secondary, projector-connected screen, dictated by the projector – setup before.
- Workaround: Make the 1024*768 left screen the primary screen.
- Upside: this allows to project the show to the class, but teacher can still move the underlying PowerPoint presentation onto the right screen (for previewing answers. The PowerPoint 2010 upgrade did fix the PowerPoint 2007 bug that interactive animations from PowerPoint 2003 where briefly revealed on slide load before they went into the default hidden state).
- Downsides:
- Presenter view is still not possible, complains about seeing only one screen connected, even though “Check” button brings up the windows screen properties dual screen.
- The Windows taskbar displays on the left screen, so teacher staging is visible to the class when projector is on (as it always was with a single screen. Only the secondary right screen added a staging area for the teacher).
- Presenter view is still not possible, complains about seeing only one screen connected, even though “Check” button brings up the windows screen properties dual screen.
- Upside: this allows to project the show to the class, but teacher can still move the underlying PowerPoint presentation onto the right screen (for previewing answers.
