I run a Macbook Pro with a 15.4 screen running at 2880x1800 and find that OK. I also use external 27inch monitors running 3840x2160 when not on the move and that is great.
The latest version of Mendix 9 also lets you undock windows out of Studio Pro so you can run them across multiple monitors.
Hope this helps.
Thanks Robert for your input. With this I am confident that the 17” screen should work out for me.
