Enter the connection details provided
- Server
- Use the host address shown in the portal, not the portal's web address.
- Port
- Enter the external VNC port provided. Port 5900 is common, but the mapped port may be different—don't assume it's the same.
- Authentication
- Use the VNC or system credentials specified in your instructions, depending on how the service is configured.
- Address format
- If the client has separate address and port fields, fill them in separately. If it asks for a URI, follow its documentation and use a format such as
vnc://HOST:PORT.
Clients can interpret single colons, double colons, and display numbers differently. Prefer a separate port field, and don't mistake a display number for a port.
Keep text readable before improving image quality
- Start with automatic or medium image quality and turn off unnecessary desktop animations. Increase image quality once the display is stable.
- When debugging code, check font edges and keyboard input. Heavy image compression can blur small text, making long commands hard to verify.
- If the pointer lags noticeably, lower the remote resolution and avoid windows that refresh frequently. Simply shrinking the client window locally won't help.
- Test symbol and modifier key mappings in a text editor before pasting long commands into the terminal. This helps prevent keyboard layout issues from changing paths or arguments.
A VNC client can't eliminate network round-trip time. GUI work across networks is still affected by latency and bandwidth. For read-only inference output, SSH may be a better fit.
