Primavera not playing nice with high resolution screen

Having tried to buy the newest version of Primavera (15.1 - not sure if it's released yet) they have sort of confirmed that even 15.1 does not work with resolutions over 1900x<whatever>

So if you've got a 3800 screen or higher, you'll need to reduce the screen resolution entirely to have it useable.

Funnily enough, Asta Power Project does 'sort of' work with high resolution screens - though the menu bars are a bit mucked up - not as bad as Primavera.

I've told them to give me a call when they patch the problem.

I realize this thread is almost a couple of years old but I'm wordering if you have any more experience with trying to run P6 with a 4k monitor.  My laptop is dying (6 years old) and I'm thinking about upgrading to a machine with a 4k monitor but I don't want to waste my time if it can't drive it properly.  FYI I regularly run P6 on a 2560 x 1600 30" monitor and it works great.  Thanks for any help you can provide.

Might be a few years too late but, have you tried changing the scaling of the display? Sometimes even if you have 4K, with zooming 3x or 4x, it still shows big font and unpractical layout sizes.

lower the scaling until it's readable and not crammed.
