Depending on what you want to project from your PC to the WAVE, there are a few options.
If you're trying to present a PDF or Powerpoint from your PC, you can actually access those files directly on the WAVE using the app Touchjet Present that's pre-installed on the WAVE.
If you'd like to share your PC desktop to the WAVE, you can use a sharing software such as Splashtop (www.splashtop.com). This will allow you to mirror your PC to the WAVE via wifi (via the Splashtop software) and be able to control your PC directly on the WAVE (using touch).
We'd be happy to schedule a video call to demo the above options and answer any other questions you may have. Please email support at firstname.lastname@example.org.
