How does it work?
If you're viewing or editing a dashboard, you can increase or decrease the dashboard text size by adjusting the zoom level on your computer screen.
Go to Visualization > Dashboards and open a dashboard.
To zoom in, press together Command and + (Mac) or Ctrl and + (Windows).
To zoom out, press Command and – (Mac) and Ctrl and – (Windows).
Dashboards vs. TV screens
The dashboard size on TV depends on the TV's screen resolution. Changing the zoom level on dashboards allows you to test and approximate how it looks on a TV so that you can see how many KPIs you can add and what size best matches your dashboard layout.
