Morning
Following on from @Robert_LeClair answer there might be something else you can try also.
In ArcGIS Pro if you go to the Project tab > Options > User Interface (it's close to the bottom of the dialog).
There is a section entitled Ease of access > User interface scaling. Possibly try 130%?
You will need to restart the application for this setting to take effect.
As you can imagine it is pretty easy to change it back.
I hope this helps. Many thanks ed
