I have 2010 Macbook Air 11", which is connected via DisplayPort to HP LP2475w LCD monitor. Unfortunately the text displayed on the external monitor has rough edges and as far as I can tell, it is not anti-aliased at all.

I searched for a solution and the one most commonly offered, such as here, did not work for me. For the record, it says to run this command in the terminal:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

Any other options?
