If you only want to show "Public" meetings on your Q-Cal SignangeViews/Screen, follow this guide that shows how you set it up.
Part 1: Turn on "Mark meetings as public if subject starts with *".
1. Log in to 
Q-Cal in your browser, and click on 
Main menu.2. Hereafter choose 
Calender Integrations.3. Click on the small 
Gear icon next to the desired calender integration.
4. Choose the 
Advanced tab under the inegrated calenders configuration. Hereunder turn on 
Public on "*". 
This mean that you need to put a "*" before the meeting subject, to have the meeting shown on a SignageView.
 If there is no "*" before the meeting subject, the meeting will not be marked as public, and will not be shown on the SignageView
A example could be: You head your own calender and in the subject field, you write: "*Meeting with Mark". That would be a public meeting.
When done press 
Save & Close in the top right corner.
