You can drive 4k with a recent macbook, but it's laggy as sin. My Amazon review: http://www.amazon.com/review/R4OJ5D5RPILCH/ http://www.amazon.com/review/R4OJ5

- mturmon 13y agoThanks for that note. I was at the Apple store in Pasadena this week checking out a new rMPB (OS 10.9.1) and the Sharp 4K monitor. They connect by HDMI, not DP, at the moment. This limits refresh to 30Hz. I did not notice the lag on text input that you did (but, I did not enter much text; I didn't think of this as a possible issue). I also did not notice any significant lag with the mouse. This may be user-dependent. The thing I did notice is poor rendering of some fonts. There were colored fringes around the system font that both the Apple rep and I noticed. Other common fonts were affected as well, but not all of them. It seemed like a problem with subpixel rendering to me. Changing the display mode to mirroring did not help. The Mac Pro did not have these problems. It's quite smooth (60Hz) from the Mac Pro. It was bad enough that it disqualified the monitor for me. I assume it's an artifact of the HDMI driver they're using, and "probably" fixable with a better driver. But you never know.
