As per the documentation - ui_resolution is a comma-separated list of up to three strings that identify the UI resolutions the application has been designed to support.

But for any public channel, we have to support enough devices which include all resolutions. Does it mean we have to make this setting always like ?
ui_resolutions=sd,hd,fhd
Also if we support all resolutions how to define the sizes and position for renderable nodes, so that we can have the same UI across the devices and resolutions?
