Small update for volumio3 - there is whole plugin prepared and working with volumio3
It allow you configure (click by click) various looks also for 1920x480 screen - but you need volumio subscription. All you need is only use my userconfig file (which give you propper size and scale settings for this kind of display).
Good news is there is also peppymeter (which works and looks awesome) plugin which is working with 1920x480 resolution (this one is available whithout volumio subscription)
