I don't know if everybody except me has known this for years, but ... I have my MacBook rigged to a Dell display through DVI, and I mostly run it in clamshell mode. The annoying thing has been that when I reconnect my MacBook after having used it on the road, I have a hard time getting anything to appear on the external display.

I used to wiggle my Bluetooth mouse, and press the space bar on my Bluetooth keyboard for some time, and keep on doing this until (eventually) the display would light up. There is, however, a far simpler solution to this problem: after reconnecting your MacBook, just switch the display off and on again and presto -- instant image!
