How does one fix the resolution of EPPM?

We're using P6 8.2 EPPM.

The resolution for P6 EPPM on one of my users computers makes the program so small it's hard to read.  The strange thing is, the user opened P6 EPPM with an older computer and the resolution is fine. This would lead one to believe the problem is with the user's new Windows 10 computer and the way it is working with the server. My IT Department has tried re-setting resolutions and other things, but they can't figure out what is causing this. See the screen shot below.

Any idea what could be causing this?

The P6 login screen should be four times larger than the one shown in this screen shot. When the program is opened, it is just as small and almost impossible to read.
