using a large monitor with macbook

um it'd be helpful to actually mention the model of macbook you have. but yes it should support external display. since you mention absolutely nothing relevant, you probably have mini-dvi out or mini displayport. the resolution that can be shown will be dependent on your model and the monitor.

 

Don't worry, you definitely provided us with enough relevant information to help you. As far as I know, (and correct me if I'm wrong), all of the old white MacBooks that came before last month's revision had the same ports, and all used mini DVI. Simple enough to figure out!

As far as what types of screens are out there...it's really up to you, and what you like! People here tend to like the Cinema Displays, and while I do too, I found that they were wayyy too expensive for me. Shop around and see what deals are out there, and also do a few forum searches, there are lots and lots and lots of discussions on the topic! There is really no general consensus of the best third-party monitor, since everyone has different needs and different tastes. That being said, I definitely like my HP monitor (model w2338h), it was in the right price range for me and has a really great display. It also just generally looks nice unlike some of the other third-party displays. What will you be using yours for - photo editing, writing, movie watching, etc??

Going from a 13" MacBook display to a 24" display was a real treat, so considering your current space issues, you should probably try to look for something in that size range.
