I've been looking into monitors and it's getting confusing. I'm ordering a new macbook pro retina. I want a monitor to hook it up to when at home. Was thinking Apple Thunderbolt, but I want an update. Is it worth getting a 4k monitor? Can I even take advantage of it using a mbp retina? I get confused by the different resolutions and how they pair up together. Basically, will I get a sharper image connecting my mbp retina up to it while web browsing, reading, watching movies/shows, and gaming?
