Applies to ElumTools on Windows 10 operating systems.
1. On the desktop icon for Revit right-click and select Properties.
2. Under the Compatibility tab, click on Change high DPI settings.
3. Check the box in High DPI scaling override. In the drop-down menu change it to System (Enhanced).
This will force the program to scale to your computer's scaling settings. This may cause some blurriness of the text but it might look better than the default settings. If it doesn't look quite right you could also change the High DPI scaling override setting to Application or System to see if it gets better results.
Important Note: This will fix ElumTools issues but may result in unknown behavior within the rest of Autodesk Revit.
