Try Fn-F7 on the Vaio laptop to switch to external VGA.

The technical explanation is that there is a pin on the plug that
signals to the display that there is a computer connected to it.
Sometimes this pin is intelligently (software) driven, as I suspect is
the case with the laptop, but is simply grounded on the desktop (many
electronics signals a "yes I am here" condition when it's a ground
potential). -- U asked for an explanation! ---

All I can suggest is, look at the male plug and be sure all the pins
that are there is not bent or pushed down. If there are pins that are
totally missing, that's normal. Other than that, find another display
and test that out to see if problem with laptop or display.
