VGA & Serial Connectors

The serial and VGA connectors are shown here in the left photo, and their respective receptacles are shown in the right.
They are trapezoidal in shape, being wider at the top and more narrow at the bottom.
These connectors fit nearly effortlessly and should never require any kind of excessive force to install.
Note that the serial cable is male on one end and female on the other, while the VGA cable is the same on both ends.
It is possible from time to time for the threaded nuts on both sides of the VGA and serial receptacles to loosen or not be completely tight out of the box.
A 5mm nut driver is used in this case to secure them.
