Many are having issues with font smoothing not working correctly on external displays with SL 10.6.
I researched this issue and found this blog posting:
http://blog.jjgod.org/2009/08/18/snow-leopard-vs-dell-lcd-displays/
the blog itself discusses the issue, and the fix is found in the comments.
Basically, for now the fix is to open Terminal App and enter:
“defaults -currentHost write -globalDomain AppleFontSmoothing -int 2″
without the quotes, and hit return.
a log out or restart might be required.
this fix seems to stick even after re-boots and shut-downs.
