@sdetweil Thanks Sam. I’ll give that a shot soon as I get a chance. I suspect I’ll mess it up… and make new questions… (as a newbie on this!!)

I make changes to my installation on a 27in monitor but run MM on a different monitor (located elsewhere in house) that uses a 14in (prior laptop) screen.

Been looking around for a module (or some code) to let MM determine which monitor (runtime env) is being used - as the font sizes and module placements need to change to due the screen size differences. Note: Rpi 3 is being moved back and forth from one location to the other such that the only variable is the monitor.

Anybody have a similar situation? How’d you handle i? (Don’t really want to use custom.css if don’t have to - as I would still need to know which monitor is being used!)
