More anecdata: Same monitor. I use the cable that came in the box. I've had it fail to detect the monitor approximately 1% of the time I plug it in -- it seems to happen once every 3 months or so. This is fixed by pulling the cable out and plugging it back in. Other than that, I habitually unplug the monitor before putting the laptop away in the evening because the built-in charger makes the fans spin up on my macbook pro.
