I've been really wanting to move over to a 4k display for some time. I started with the LG 31MU97, but with the bugs and lack of proper OS X support, I exchanged that for a 34UC97. The only issue is that this is a larger screen at a lower resolution. While I like the wide ratio, I would like something that is a bit sharper looking. I have the opportunity to do an even exchange for a Dell UP3214Q, which seems like a good deal since it retails for $2500. I've heard many of the sleep issues people had with this display are now fixed since the A01 firmware. Anyone using this 4k display with OS X? Any thoughts on this?
