Consistently connecting to an external monitor

Is there a correct sequence for turning on, and plugging in, my MacBook Air, to make it play nicely with a generic HP external display?

My Setup: 2011 MacBook Air, with an HP L1910 external monitor, connected via the thunderbolt port with a mini-dvi to VGA adapter. I like the external display as an extension of the MacBook screen, not a mirror.
The Problem: When I plug the mini-dvi adapter in, the MacBook display fades blue and fades back again as it changes screen resolution, but the external display does not consistently "turn on". I end up in a frustrating roundabout of unplugging and replugging the mini-dvi adapter, repeatedly hitting "Detect Displays", trying to adjust the screen resolution, and turning the external display on and off. Some or all of these things are usually eventually effective, but I am not clear what it is that eventually makes the external display spring to life.
The Question: Is this a screen resolution problem, or something about the sequence of switching on / unsleeping the laptop or the display, or related to the timing of plugging in the connector? Or are these connections just flaky?
