HiDPI on Inventor 2015

[Anonymous]

 Hi everyone, 

     I didn't know where to post this so I thought customization was the best.

     I recently got a new Dell Inspiron 15 with a 4K as a gift, but when I booted Inventor 2015 to pick up with my work from where I left off, I was met with very tiny icons, rendering it almost unusable. I've tried changing the registry to prefer an external manifest, but it just made the program fuzzy and spontaneously crash. I've also tried scaling the display and changing the resolution from the native 3840x2160, but it just makes everything that was tiny normal and everything normal massive. 

      Is there a change I can make in the application settings in order to fix this? I can't upgrade to 2017 where this issue is fixed because the others I work with use 2015.

      Thanks, Neil
