Configure VNC Server Start the server with `vncserver` and set a password when prompted. Then configure display resolution.
Port Forwarding Forward port 5900 + [display number] (e.g., 5901 for display :1) to your Raspberry Pi's local IP address.
Connect via VNC Client Use a VNC client (e.g., RealVNC Viewer, TightVNC Viewer) and connect to your public IP address:[display number] (e.g., 192.168.1.100:1).
Security Choose a strong VNC password. Consider using SSH tunneling to encrypt the VNC connection.


3. Exploring XRDP for Remote Desktop Access

XRDP offers an alternative to VNC for remote desktop access, using the Remote Desktop Protocol (RDP). XRDP is compatible with Windows RDP clients, which makes it easy to connect from Windows machines. It provides a similar functionality to VNC, allowing access to the Raspberry Pi's full graphical desktop.
