Just trying now with a 1920x1200 monitor (HP Compaq LA2405x) and I'm still seeing the same problem.

On the left most part of the monitor, I can see 1 column of pixels that belong to the content that is in the right most part of the laptop. Strangely, it does not show up when I try to do a screenshot, but is quite evident when watching a fullscreen movie in the monitor, for example.
