I've been doing research on external monitors and have narrowed it down to Samsung and HP. Right now I'm set on 19inches because I'm unsure of how the Macbook will perform on something like 22inches. Does anyone have any information on monitor choice and also the size? Also when I was researching on the forum someone told a guy he would need a converter to use a certain monitor for his macbook.... do I ned this or do I just hook it up and go?
