Dashboards refresh automatically

We would like to make our own dashobards available on a screen for everyone. But we have the problem that they do not refresh automatically.
On the “Views” there is the “Automatic page reload” but not on the dashboards.
what have i overlooked or how can we implement this without 3 party browser refreshers?

In your Dashboard click on the Top-Menu Dashborad > Enter Layout mode.

Then you can click on the gear for every view in the dashboiard and set the “Automatic page reload” individually.

Not all views have the “Auto reload page” option, e.g. the barplot, service statistics, combined chart etc. do not have the “Auto reload page” option.
There must be an option for a dashboard, otherwise it makes no sense to me.
