Using the Stretch mode already fits your remote screen to the local monitor (i.e. it shrinks or stretches the remote monitor). In order to get rid of the borders you can try resizing your Full Control connection window to better fit the remote screen resolution or you can also try using the Fullscreen stretch mode instead and see if it works for you.

In addition, if the above doesn't help, please try resetting the Viewer's settings: 1. Fully exit the Viewer (File→Exit). 2. Go to the C:\Users\[Your_username]\AppData\Roaming\Remote Utilities Files\ folder. Note that the AppData folder may be hidden by default in which case you'll need to turn on Hidden files and folders in Windows Explorer settings. 3. Locate the file config_4.xml and delete it. 4. Run Viewer and register it with your license key once again. 5. Try using the MSI Configuration tool and see if it works for you this time.
Please try enabling the Use legacy capture mode feature in the Host Settings -> Other tab and see if this helps to resolve the issue. After enabling the feature please make sure to restart your Hosts for the changes to be applied.

Could you please answer a couple more questions: 1. Does the same apply to both “admin”/“Johns” accounts when using Full Control connection mode as well? 2. Does this occur for only one specific folder or were you able to reproduce it for multiple directories in the Registry Editor?
Could you please clarify if you’re running Viewer as administrator? Are you able to see this folder if you open the Registry Editor directly on the Host machine (either physically or via Full Control connection mode)?
In this case, can you please export the Windows System Events logs following this guide. Please make sure that the logs include the time period of when you’ve experienced RU Server crashing. You can send the log file to [email protected].
