What is UltraVNC?

UltraVNC It's an open-source remote desktop program that uses VNC and the Remote Frame Buffer (RFB) protocol to display the screen of another computer over a network or the internet, allowing control with a mouse and keyboard from your own computer as if you were sitting in front of the other computer. The program divides the work into a Server for the computer needing access and a Viewer for the connected computer, making it suitable for troubleshooting, maintaining, or accessing computers located in different locations. If you're familiar with... Anydesk The workflow is similar, but UltraVNC offers more detailed customization options for connection and server-side elements.

The Viewer side offers a fairly comprehensive set of practical options, such as View Only for viewing the screen without mouse or keyboard input, Auto Scaling for scaling the image to fit the window, Full Screen, and the ability to select a single window or the entire desktop. Additionally, it allows you to use Ctrl+Alt+Del to refresh the screen and adjust connection settings from the Viewer menu during a session. The Tabbed Viewer allows you to open multiple connections in a single window, making it easier to switch between managed machines without opening separate full-screen windows.

UltraVNC also features File Transfer for sending files or folders between two machines, with data compression during transfer, and Quick Chat for communicating with the recipient without needing to open an additional chat app. The connection supports the DSM plugin for data encryption and is compatible with RealVNC, TightVNC, and several other VNC applications that use the same standard. This is very useful when the environment doesn't use the same program on every machine. These functions make UltraVNC more than just for viewing screens; it's quite versatile for remote assistance, file transfer, and managing multiple machines from a single point.
