Prime Emulator on Surface Pro 4

[ThomasA]

Hello,
I have just installed the emulator on a surface Pro 4 (Windows 10).
The emulator is running well, but it is so small that it is nearly impossble to work with.
I tried to magnifiy the skin using Windows's on board tools (adjusting the display, factor 200%) but that is not enough. (I am not an experienced user of Win!)
Does anybody know a solution to this? Or is it just the Surface display specs of 2736x1824 pixels which causes the problem here?
