I have a macbook pro, and an imac. I want a larger display for my macbook. So i was thinking of selling my imac and getting a 30 ACD. Then i started looking at dells. I noticed they have newer models with a higher contrast ratio. Then i started looking at the lower priced dells and they have a higher contrast ratio than apple's. (how is that possible?) anyway. I started looking at the low end 24"dell because it has a nice price, and I could hook it up to the macbook pro and the the imac, when the macbook pro is attached. Just wanted some advice on what the best thing to do is. I don't mind the way the dells look, and i like that they rotate vertically, but i did actually by on once about a year ago, and there was so much banding i returned it instantly. But maybe they've changed it since then.
