Hi, I just want to ask something very specific. I did a search in these forums for an answer, but as you can imagine, the words "MacBook" and "external monitor" appear quite often. Anyway, I'd like to use my MacBook hooked up to a 20" Dell 2007 WFP (got one with an S-IPS panel as well!!). I'd like to do so without using my MB in clamshell mode because I like my MacBook's keyboard, although I'll still use an external mouse. I just don't want the MacBook display on because it's still using 32 MB of total RAM, leaving only 32 MB to run my external Dell display. So is there a way to only use my external 20" display, turn off my MacBook display, and do so without putting it in clamshell mode so that I can still use the keyboard?
