Well, mine is DL1000 2018 but if it helps, from the highest point of the dash to the top of the screen 19 cm. That is, using lowest mounting holes for the base screen and adjustable screen fully closed to its lowest settings.
In my case, as I use mid holes it is 2 cm more.
However, I'm 6'2.5 and I use the base screen on mid holes and adjustable screen half way extended. I have a lot of space looking over the screen.
