Depending on what you want to project from your PC to the WAVE, there are a few options.
For displaying PDF files or slideshows (like PowerPoint), we recommend using the Touchjet Present app which comes pre-installed on every WAVE.
To remotely access a laptop or desktop computer the WAVE, we recommend a screen-sharing software such as Splashtop or TeamViewer. This will allow you to mirror your PC to the WAVE via Wi-Fi (via the Splashtop software) and be able to control your PC directly on the WAVE using touch.
We are happy to schedule a video call to demonstrate the above options and answer any other questions you may have. Please email support at firstname.lastname@example.org.
