::where <i><b>:xx</b></i> is the new port number. This port number corresponds to whatever port was chosen while making the PuTTY connection (L59xx, gluey.phys.uconn.edu:59xx). In the example above the user created a port at 5992. The options <i><b>-depth 24</b></i> and <i><b>-geometry 1280x720</b></i> are not required and the geometry can be any resolution. After creating a VNC session the only way to change the geometry is to kill the session and make it again.
