Hello,
I’m trying to have the title barchar font bigger so everyone can read it better.
I’m using grafana on a TV in kiosk mode.I can’t find the options to have bigger font sizes.
Grafana v 9.0.5

I don’t we have a way to increase titles across the board. You would have to fiddle with the code and then build Grafana from source
