After realizing the Recipient Settings, you can have a look at Controller Settings.  Go to Settings > Controller and you can see the three items: Image Quality, Hide the desktop wallpaper, Save the security code

Controller Settings


Click the inverted triangle under "Image Quality" and you can set the image quality of the remote desktop window that will present to high quality or low quality. Or you can leave it alone and change the image quality during the remote session. 

Enable "Hide the desktop wallpaper" can make the wallpaper of the Recipient hidden during the remote session for a smoother display. 

The "Save the security code" is enabled by default. Once you have entered the security code, the software will save it for the next automatic connection. If you disabled the option, you need to input the security code again even you have connected the Recipient.
