EDIT: Aha! Yes, if I edit the manifest in Vegas and tell it dpiAware is FALSE, everything scales correctly
Hi - I have the same issue - had it in Win 8 and now in Win 10. Sony said "Vegas Pro 13 is not optimized for display on very high-DPI monitors..."
I'd like to try your solution, but I have no idea how to edit a manifest. I did some research but could not find anything "simple" - maybe I'm missing something.
Please let me know, or direct me to where I can find out how to do this.
