    I recently just bought an Acer S231HL for my 13" MBA. I have it connected via HDMI (though a mini display port adapter). When I am in clamshell mode, the F1/F2 keys that normally control the brightness, do not work. Any ideas?

    That's the way it is (at least with the monitors I use). You need to adjust the brightness on the monitor itself.
