So the 2011 iMac has a thunderbolt port only for hooking stuff in, and the cintiq needs either dvi or vga to work. But I wanted the opinion of people more knowledgeable than me on the matter on which adapter I should get, and which will give me a better picture. I was also eyeing this off-brand dvi to mini display port adapter which is super cheap! Almost too cheap vs. the apple brand one, making me wary of it functioning, even though the reviews are pretty good. http://www.amazon.com/DisplayPort-F...Laptop/dp/B003BHHIA4/ref=cm_cr_pr_product_top Anyway, any advice on the matter is welcome, thank you!
