The majority of the global workforce is now working remotely, and this trend is expected to continue well into the future. You may have handled a remote team before, or this may be your first time.

  • The tight encoding mechanism helps optimize picture quality in case of slow or intermittent connections.
  • Windows and Java viewers can resize their remote desktop for smaller screens. They can also zoom into any area of the remote screen for a better view.

3. UltraVNC

UltraVNC is an open source remote desktop app that uses virtual network computing (VNC), an RFB protocol, to set up remote desktop sessions. For remote PC access, the system sharing its desktop must run a VNC server, while the system accessing the shared desktop must run a VNC client. Screen sharing, file transfer, and remote support are some key features of the tool.
