If the local computer you want to display the desktop on is Linux based then there are plenty of native Linux VNC clients - the default one for Ubuntu is called Remmina. I'd only suggest using TightVNC as the viewer (client) if you're on Windows.
BTW you REALLY should tunnel the connection over SSH - raw VNC is *not*secure and your VPS will likely be flooded with connection attempts if you leave the default VNC port open
