I am wanting to buy an LCD display. I'm not sure what makes a good one. What makes one better than another. For instance what should I look for, high contrast ratio? For instance this http://www.macmall.com/macmall/shop/detail~dpno~372518.asp one is cheap, but is it good? What would be a good resolution for the size? How is DVI better than VGA? I need education on the subject. Is there an article on how to tell a good LCD from a crappy one? Thanks for any help you can give.
