VGA is not as capable of driving certain display resolution/refresh rates so it is being rolled out as an outdated technology. I personally am liking the move forward to Digital connections, HDMI is a favorite because it will transport audio as well and a tone less annoying than VGA and DVI to use.
However if you have DVI there are simple adapters that will turn your DVI port into VGA and they are rather cheap. so if you don't feel like updating your monitor yet (especially on a server) you can get something with a DVI port on it, and then reconnect to a VGA connection.
The adapter is pretty dang cheap, and i have several leftover from graphcis card purchases in case you do not want to wait:
