No doubt - well made, beautiful picture, minimal glare, no obvious dead pixels. Instructions are a bit minimal, but not too hard to figure out how to set it up. Internet (not Dell !) is helpful for information. As noted you will get no hand-holding from Dell. Their web site, worse their support techs have no clue! My intention with this monitor was to run it with a late 2013 Mac Pro (AMD FirePro 700 GPU). This has been a long strange trip! Image is fine grained and beautiful, but no 5K. Best I can get is about 4K. (3840x2160@60Hz). Using 2 cables as suggested by Dell to overcome the Display Port 1.2 inability to carry 5K - doesn't work. I'm currently using one cable and for general computing, 1920x1080 is sharp and perfectly adequate for most of my needs. I should note that I called Apple and spoke with 2 techs. One billed himself as the senior tech on duty. Unfortunately, no help here either. The video driver to combine the feeds on this card doesn't exist as yet. Strange that AMD has released an update to one of its PC retail cards that will permit exactly what I want. Maybe Apple will come along? More likely they will wait for DP1.3 (ThunderBolt 3) and then come out with a new MacPro and a new monitor to take advantage of this so as to provide 5K.
Can the Late 2013 Mac Pro drive it?
Still looking, but signs for the older Pro don't look good:

"Waiting for the Dell 5K monitor?
We dont know whether it will work with the current Mac Pro yet. Just like the theoretical Apple external 5K monitor, it will rely on tricks like MST to be treated as one big monitor, which may be unsupported or buggy on the Mac Pro.

From an Ama*on.com review:
I'm starting to think NO is the correct answer right now. Only the 5K Retina iMac can run OSX at 5K right now (Feb 2015) it appears.

My best efforts indicate everyone reporting a fail.
I think DP 1.3 in future Apple products is what will be needed for this monitor.
You CAN however, run it at 4K.

"As a result, no current Mac, including the Mac Pro and Retina MacBook Pro models that do support 4K displays, can currently drive a 5K external display. Technically, Apple could allow another Mac to output video at a lower resolution and have the Retina iMac scale the content up to fit its display, but this would not be ideal and Apple has apparently elected not to support it as an option."
I would have to assume it's on Apple to make it work via drivers? If OS X isn't setup to send two mDP signals to a single display then you'll just get the max UHD resolution one mDP cable can provide.
I think so. But they are worried, I think, about the performance @ 5K on existing hardware, and would probably prefer to wait until DP 1.3 is available on their devices, and maybe even TB 3.

Well, in that case the P2715Q seems to make more sense, no?
Now, on Windows, display is super clear at 5k, but you can only use 1 of these displays, and it has to be plugged into the bottom (horizontal) bus. If you connect more than 1, or if you use another TB bus, you'll either be resolution limited or completely not working.
Anyone know why? I'd love to have 3 of these working under Windows.
Yes to all 3
But why only the horizontal/bottom bus?
For drivers, no, using what boot camp installs but may try omega, assume this is a beta release?
Now it would be great to know if the 10.10.3 beta adds 5k support finally.... It´s time, really...
Time has come, and yes, it works!
yourself tested?
this topic in apple support page (https://discussions.apple.com/thread/6984465) , open today, people are saying q does not work
Feast your eyes.Can you post a screenshot ?
