To resolve these issues, we will elaborate on two methods. One in Remote Desktop Manager, and another using a built-in Windows functionality.
First, in Remote Desktop Manager, go in File - Options - User Interface and please uncheck “Disable display scaling on high DPI settings.”
If you cannot see the setting because of display issues, you can add the line in your config files directly. To locate your config file please refer to Configuration File Location. Once you have found the right folder, please open RemoteDesktopManager.cfg with your preferred text editor. Under the line “<CreationDate>2016-11-14T00:00:00-05:00</CreationDate> please add, “
Restart Remote Desktop Manager and the problem should be resolved.
The second is directly with windows options.
Right-click on your Remote Desktop Manager icon. Go to Properties and in the Compatibility tab check Disable display scaling on high DPI settings.
When applying this change, you must log off and log back in with your user for changes to take effect.
