Deleted original suggestion as it was unnecessarily cumbersome.
Changing the properties --> Compatibility --> Change High DPI --> High DPI Scaling Override to System on '
URCFrame.exe' (noted in a post above by DJ Garcia), has solved my CCP scaling problems.
This does not fix the issue of having to resize the window once CCP is opened.
