Bought this for my up and coming Mac Pro which won't be here for another couple months. Works on my late 2013 13" rMBP at 3840x21 Bought this for my up and coming Mac Pro which won't be here for another couple months. Works on my late 2013 13" rMBP at 3840x2160x30Hz as advertised, but also shocked that my Mid 2011 27-inch iMac, not advertised as able, is actually driving it at this same full resolution & refresh rate (with AMD Radeon HD 6970M 1024 MB) using the DisplayPort cable that came with the display. Slightly slow and jumpy, but the resolution is full and legit. Text looks better when display installed upside down as the subpixel text rendering expects the pixels to be divided R-G-B and this monitor has it reversed, B-G-R. Until OS X supports B-G-R natively, the included stand allows upside down mounting and then simply rotate it 180 degrees in system preferences. …

Absolutely the best overpriced item I have ever bought. The colors are brilliant and come as close to my prints on my Epson photo Absolutely the best overpriced item I have ever bought. The colors are brilliant and come as close to my prints on my Epson photo printer as no other display I've used before. It definitively beats any Apple display (including "Retinas"). Mounting and setup was a breeze. This is an absolute must have for anyone willing to spend the extra buck as an early adopter of new technology. I have also found the price Apple sells this item at to be decently competitive. …

2 X 4K on Haswell/Nvidia rMBP!!!
Just installed TWO Dell UP3214Q on a late 15" 2013 rMBP with discrete Nvidia GeForce 650m. Let's remember the Dell 4K, which has t Just installed TWO Dell UP3214Q on a late 15" 2013 rMBP with discrete Nvidia GeForce 650m. Let's remember the Dell 4K, which has the same IZGO screen.
DisplayPort 1.2 can be enabled on the Dell OSD.
On MacOS X Mavericks, the rMBP runs it's screen at full res @ 60Hz, the 2 4K monitors at full res but only @ 30Hz.
In Windows 8.1 in bootcamp, the rMBP runs it's screen at full res @ 60Hz, the 2 4K monitors at full res @ 30Hz refresh if DisplayPort 1.2 is disabled, but can only run it's screen and ONE of the 4k at full res AND 60Hz with DP1.2 enabled.
INTERRESTINGLY, if you "SOFT disconnect" the rMBP own screen it will then drive both 4K monitors at full res AND 60 Hz, WOW!!!
There you have it. The late 2013 runs 2x 4k screens at full res. …

Like most people writing a review WOW!.... this monitor is stunning. But on the other hand the resolution is so high that the men Like most people writing a review WOW!.... this monitor is stunning. But on the other hand the resolution is so high that the menu icons and text are soooooo small. I've tried to research a way to make the fonts and icons larger, but no luck. If anyone has a trick or answer I would appreciate knowing. I run Mac Maverick system software. When viewing a web page you can increase the size by pressing "command" and then the "+" sign, but when youre not on the web you are constantly squinting to see the small fonts. …

Amazing screen, pretty bad build quality. I want to love it. I really do.
I just received this for use with a mac pro 2013, which has yet to arrive. I'm using it with a macbook pro retina, which works ext I just received this for use with a mac pro 2013, which has yet to arrive. I'm using it with a macbook pro retina, which works extremely well (and if you're considering using one with this monitor, it's epic good). Being awesome, the monitor actually comes with a thunderbolt adapter cable which fits perfectly, and all I had to do was plug it into one of the thunderbolt ports on my MBPR and it worked perfectly! It worked with no fuss. Good stuff.
This monitor looks good. It's bezel isn't overly wide (kind of reminds me of a thin version of the old Dell 30" monitors, the 3008WFP beasts). It has a black on black finish with silver plastic highlights on the legs and the top, which looks a little cheap honestly (very 2008 Dell). The picture is bright, and refresh is acceptable for the graphics work (Adobe Suite for video and graphics) for which it is intended (there is a perceptible delay moving it around, but that's what you get with a huge monitor... apparently this thing is running at 60 Hz since 10.9.3, but it's very hard to tell honestly).
Here's what's wrong with it. The thing has buttons that are hidden on the right side of the screen, which is forgivable. But they completely lack any marking that can be seen from the front (including power), and feel like some cheap Walmart television rather than a multi-thousand dollar monitor. And you better hope that you don't type hard, because the stand is so cheap that just typing on my keyboard causes the monitor to wiggle visibly. You can tell that the attention to detail extends to the firmware, where brightness is labelled "Bright" and adjusting settings has a considerable delay. To boot, the menu feels like a tv in a cheap hotel room, with chunk text and setting defaults that would please nobody but the idiot product manager that approved the design.
Once you get past all of this ghastly product design and find yourself firing up FCPX to look at footage from a GH4 or other 4k camera, you realize that it is not worth returning the monitor due to it's myriad of stupid product decisions, and that you're going to learn to live with it, because this screen is absolutely stunning, and editing 4k footage on a 4k monitor is beyond pleasant: it's gorgeous. But it also identifies itself as a television in System Information, which is decidedly telling.
I am currently shopping for 200 mm pitch VESA mounts to eliminate the movement that's giving me a headache, but I love this monitor. It won't be hard to unseat it as a champion however, because it's off like a herd of turtles and needs a firmware update so bad it's like a pogo stick in quicksand.
Buy it, you'll love it. But be prepared to pay the price of early adoption. In other words, this is a "cautious buy": you should only buy this if you need it. Otherwise, wait for it's successor. …
