For best results (i.e., to not have tiny, unreadable buttons and text) when running EpicTable 1.x on a 4K display, you need to customize the way Windows launches it. 

1. Right click the EpicTable shortcut on your desktop or in the Windows start menu.

2. Select "Properties".

3. Select the "Compatibility" tab.

4. Click the "Change high DPI settings" button.

4. Make sure both the Program DPI checkbox and the "High DPI scaling override" checkbox are checked, and that "System" is selected for "Scaling performed by:".

That should make EpicTable go back to looking like EpicTable on your 4K display. I suspect this would also work for the pre-4K, high-resolution screens as well. If you find some other combination works better for you, please let me know. Thanks!
