I have this posted in the peripherals section but nobody goes there. 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?
Hi,
Well, you can hook your rMBP to the monitor using DP 1.2a in the Thunderbolt port. Theoretically, that should provide you with 4k resolution at 60Hz. However, all evidence up far claims that the frame rate will be limited to 24Hz (or maybe 30Hz). Unfortunately, I don't think anyone here has actually purchased a 4k monitor yet and tested it out over thunderbolt (DP 1.2). Some members might have 4k monitors, but those usually don't have miniDP connectivity that the Dell monitors offer.
If you're planning on getting the 24" monitor, it'll run great in HiDPI mode; it'll be like a 1920*1080 retina display. The 30" will work like that too, but 1920*1080 on a 30" display is quite unappealing.
As for your question regarding sharpness, it'll be somewhat like the difference between the display of a cMBP and that of an rMBP. However, with external monitors, the difference isn't that great. Personally, I would rather have the screen real estate of a 1440p 24" monitor than the sharpness of a 4k monitor running on HiDPI mode.
Finally, watching movies will be great, but you don't really have much 4k content available. If you do find some 4k movies, you'll love the sharpness and clarity. I don't think you would want to read a book on such a big screen, but the text will be a tad sharper if you do. Forget about gaming; the resolution is too high for your rMBP to handle in proper gaming. Furthermore, if the refresh rate is limited to 24Hz, your game will be far too choppy anyway.
If you end up getting the 4k monitor, do test it out over DP and report your result here.

UPDATE: Just to clarify, DP 1.2a is only available in Thunderbolt 2, so you won't be able to use an older rMBP for potential 4k 60Hz output.
