WARNING:
******* 
If you are going to connect a TV or Overhead-Projector to
your computer, it is best to connect the TV to the VGA/HDMI
port on the computer **BEFORE** booting up the computer.

Otherwise, when you connect the TV or Overhead-Projector to
the computer, your computer screen may be suddenly reset to
an inappropriate resolution. Some (older) Linux distros may
not return to the original resolution after powering down
and rebooting the computer. You may need to do web searches
to find a way to reset to the proper desktop resolution.
