Ah OK, luckily they're on this article too :D I use two as you see. The lower one usually shows the Mixer, the upper one the arranger part of the DAW (on Pt.3 you see a screenshot taken over both monitors -> last image). When it comes to plug in's at the end of mixing, a third screen would be no mistake :).

The upper monitor is a Touchscreen and can be tilted. This way i can move it 'into' the rehearsing room, to control the DAW while recording.

Btw. i did a post on the rebuild of the room

Thanks for all the engage and pizza token, i will flush it with a beer ;)
Cheers and enjoy your day @steevc!
