Every time I go to my sisters house I am amazed at how great her 27 inch (non-retina) iMac is. I wish I could get one, but it's a bit expensive at this time. I have a MacBook Air already, so I figure my best option is to just buy a monitor to use with my current laptop. I would love a Thunderbolt display, but that is too expensive as well. I am basically looking for a decent 27 inch monitor with 2560 x 1440 resolution. There are many options out there and I am completely lost. I don't do video games or any type of image or video editing. Basically just web surfing and business stuff. I want a big monitor so I could fit multiple windows on the screen simultaneously. I'd like it to look sharp, but I don't need it to be extraordinary. Is there a best value 27 inch monitor out there?
