I was wondering if there is any encryption for keystrokes and/or clipboard put into RDP connection. If someone is monitoring your traffic, would they be able to see what is input? Is there a way to change the encryption settings?

Yes it is encrypted.

RDP is based on, and an extension of, the ITU T.120 family of protocols. RDP is a multiple-channel capable protocol that allows for separate virtual channels for carrying device communication and presentation data from the server, as well as encrypted client mouse and keyboard data. Source

By default, the encryption is set at a default level setting of Client Compatible (medium)

To increase the encryption level used by RDP through Group Policy. To do so:

  • Open Group Policy (run command is gpedit.msc)
  • Open Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security.
  • Select the Set client connection encryption level
  • Enable the setting and then choose the encryption level, located under the Options section
