I have a MacBook Pro Retina, 15-inch, Mid 2015. I am looking for a good monitor to hook up to it. I don't need a 4-5 hundred dollar monitor. Just something that will have enough real estate on it to have Xcode open and maybe one other window as well, but at the same time not not have any lack in good graphics. Would like to go with a 27" and be no more than around $350. What would you recommend?
