Yes ... the P2715Q is working great with both the RiMac and my cMacPro at full 4K resolution and 60 Hz.
Thanks! To make it work, exactly what did you do and/or did you need to use any different cable other than the one came with it?
I tried several things including SwitchResX with no "apparent" success. Then I moved the supplied video cable directly to one of the RiMac Thunderbolt Ports and it all started working perfectly. In an attempt to clean up the installation at some point, I had moved the monitor cable down to daisy-chain through a ThunderBay IV disk enclosure.
I wish I had noticed and tried that first ... then I would know for certain if that was really what fixed it, or some combination of things I had tried. I couldn't "undo" all the trials to check for sure.
Are you having a similar problem?
Mst sst?
Hi there,
I've just bought the P2715q to run with my late 2013 Macbook Pro retina with discrete graphics.
Just wondering whether I need to run it at MST to get the 60hz?
Or is that done automatically?
I don't know really know what MST and SST mean, but because I'm using the one monitor, does that mean I don't need to run it at MST?
Cheers

Use the one cable that comes with the monitor and that should be enough.
SST is better, MST is mainly in first gen, where the display is basically divided in half and they are being rendered as two screens.
P2715Q Shared With a PC & Mac
After auditioning a retina iMac late last year, the clarity of the display, text in particular, was the nudge to replace my 26" monitor. It was great in 2007, but at 89 pixels-per-inch (25.5" diagonally), text and image clarity left much to be desired. I would have preferred a bump in physical size (32") but price was a major consideration. The P2715Q has excellent reviews, comments here and elsewhere were very favorable, problems seemed minimal, and with an IPS display, 3 year warranty, real buttons, and a price of $513 after discounts, it was hard to pass up.
Having used Dell gear for over twenty years, the monitor build quality is excellent and better than some of their cheaper business-class monitors I've used. Colors are good, text is sharp, and on my nMP (OSX 10.10.2), it works at native 3840x2160 or scaled to 2560x1440 without a problem using FCPX and Motion. The screen flashes a couple of times when a TV connected to the nMP turns on and off, but otherwise, I haven't had any problems. That said, it works great for me but if you're going to use multiple inputs and a PC on this, or any 4k monitor, keep reading because I had a few surprises.
Since 2008, I've used a KVM switch to share a keyboard, mouse, and monitor with a PC and 2008 Mac Pro. Last year, I upgraded to a nMP with the same setup and never had a problem at 1920x1200. I knew I'd have to abandon the DVI video connections on my KVM and go direct with DisplayPort cables for the P2715Q but didn't anticipate any problems. I was wrong.
My comments below are not pointing out any fault with the P2715Q monitor and I'd probably have the same problems with any 4k monitor or one that use DP connections, all because of Windows 7.
The nMP is on the P2715Q DP port and a Win7 PC is on the mDP port. As mentioned earlier, the nMP works great with the new monitor and I have no complaints. The PC on the other hand, takes all open windows, resizes them to a small size, and places them in the upper left corner of the screen every time the monitor input is switched or when the monitor is turned off. This happens because DisplayPorts are plug-an-play (PNP) and a PC polls for a signal that lets Windows know if a monitor is connected or not. It only took switching the monitor input between my nMP and PC a few times to realize that this was a major problem unless resetting application window sizes and positions was something I wanted to do constantly.
Switching DP inputs on monitors with multiple systems has been known to cause problems for years where Windows is involved but I wasn't aware of it. There are plenty of "fixes" that claim to solve the problem and I tried registry changes, Windows setting changes, and other assorted software hacks that were all guaranteed to work, but none did. A recommended hardware fix was to pull out a DP cable pin (or tape it) but that was something I was hesitant to do. Luckily, I stumbled across Ninjacrab PersistentWindows, which is a small alpha version app that restores window sizes and positions after switching inputs. While not perfect, it works well enough most of the time and hasn't caused other problems.
At 2560x1440, Win7 is relatively stable and I only have have a few problems. In some applications, the mouse doesn't respond right away and images don't always pop up instantly on screen as they should. It's pretty annoying and I'm still uncertain why I'm having the problem. My keyboard and mouse are still on the KVM and nothing has changed at that end. Getting sharp clear text is an issue at this resolution and I've been trying different fonts and tweaking Win7 custom text sizes and the Windows Color and Appearance panel to get sharp text that works for me. HelveticaNeue has been the best font as long as Clear Type is turned on. I have a few problems with my AutoHotKey script but again, I'm not quite sure why.
At 3840x2160, mouse behavior is very sluggish with specific applications and I have the same problems as with the lower resolution. I can easily adjust for clear sharp text that's identical to what I see on my nMP, but have major issues with window instability. As an example, when I grab a side or corner of an open window to resize it, when I release the mouse button, the window usually resizes itself so it's much smaller. This happens with every open window and the only way I've found to get around it is to grab one side, drag it to the edge of the screen and let it go. Then, I can grab the side again and position it to where I really wanted it. This works but is a real pain. Windows also jump around occasionally, changing position on screen as if someone else was moving them.
Photoshop CS2 is unusable at 4k and the tool panels are so small that I can barely identify them. The Move Tool arrow looks like three tiny squiggles and I need binoculars to even see the Marquee selection crosshair. I've read that 4k screen issues been fixed in CC versions, but that's not what I have.
In either resolution, applications that use the Windows fonts and settings generally have a good appearance. Those that depend on their own font settings are hit or miss. In most cases, I can adjust them and get text I can live with, but it's not often the sharpest text possible.
I'm on the fence as to whether to keep the monitor. It works great on my nMP and the Windows issues aren't caused by the monitor. Getting a different monitor, 2560x1440 for instance, probably wouldn't solve anything because if it used DP ports, I'd still have problems. I have an AMD 7950 3Gb video card and while it could potentially be causing a few problems, I see others having problems with Nvidia cards. The Win7 issues have been around for years so the chance of Microsoft fixing it to play nice at 4k is slim to none.
Perhaps some of you have a PC and Mac sharing a 4k monitor without any problems. Any advice or comments about the Windows or DP issues would be most appreciated.

flickering with P2715Q on MacPro
I just got this monitor and it seems to occasionally flicker with a late 2013 mac pro w/ the D300 video cards in SST mode w/ 10.10.2. Just switched to MST to see if it will resolve the issue. This is definitely a driver issue as it doesn't occur in bootcamp

Does it look like this? https://youtu.be/Rj8QwgzogqQ
I had flicker issues with a Samsung U32D970 SST display. I returned it because swapping cables didn't help.
Yep. Looks like its an osx SST bug. I bet if you had switched to MST or bootcamp it would have stopped.

I'd try 10.10.3 beta if you can.
Hmm... I have the same Mac and I have two of the P2715Q's, and no flicker what-so-ever in OS X 10.10.2. The vast majority of the time, I'm using HiDPI 1920x1080.I just got this monitor and it seems to occasionally flicker with a late 2013 mac pro w/ the D300 video cards in SST mode w/ 10.10.2.

I do occasionally see flicker in Boot Camp W8.1, but I figure it's graphic card driver issue... I should check to see if there are any recent updates from AMD.
I'm starting to wonder if it's a specific issue with some D300 systems? I haven't heard many, if any, D500/D700 issues with SST monitors but a few like mine with the D300. Another poster on Apple Discussions has the same system (base model) and the Samsung monitor worked fine. I even took it to the Genius Bar and they said they couldn't find anything wrong.
Unless there's something wrong with the system, almost all the issues I've read about seem to eventually track back to the display cable or the display itself. Have you tried a new cable? That seems to fix a lot of these issues.
I didn't mean to derail the thread but yes two cables. First the one that came with it (DP-DP with a mDP dongle) and a 3rd part Accell DP-mDP cable. Same issue with both and two monitors of the same make/model.
I think a lot of time on the nMP configuration, followed this thread from the beginning and I ordered 2 days ago P2715Q and nMP D300
I hope it will not be any flickering.
After read this thread I'm lost.
Can nMP handle 3x P2715Q @60 Hz or only 2x @60 and 1x @30 Hz?

I haven't been actively participating in this thread as I've got my eyes on the LG 31MU97 4K display which apparently runs at 60Hz under 10.10.3. However, I digress. It's already been suggested that it's worth checking the cables as those seem to be the cause of flickering issues on 4K screens. I've specifically read people saying that using any kind of dongle is a big no-no. If you need to go from mini Display Port to a full sized Display Port use a cable that has the correct sized adapters at each end and avoid a dongle! The aforementioned LG ships with one of those so cables like that do exist!

I also have a D300 nMP and was concerned about how good the cards will be, particularly when using scaled resolutions on a 4K screen. I spoke to an Apple representative about it and after some research he called me back to advise that the D300 will cope absolutely fine with scaled resolutions on a 4K monitor, however Apple recommends we only use displays listed on their support page: https://support.apple.com/en-us/HT202856

https://forums.macrumors.com/posts/20627074/.
The 3rd Uhd/4k monitor is only 30Hz. Great example (with setup image) earlier in this thread (#592). But probably not running the D300/? Upcoming Yosemite 10.03.03 may improve the 4k monitor drivers, but the 60/60/30Hz limitation probably won't change until the nMP(7) eventually arrives.
In OSX yes to 3 as long as they are on different buses
In Win, you could likely support up to 6 at 60hz
It is an OSX driver issue not hardware
Realy? What's wrong with Apple?
Unfortunately I love OS X and I don't want to think about any Windows (wasted too much time on this system - starting from 3.11).
I currently have Eizo EV2736W (native 2560x1440). Now I think about 2x P2715Q. I ordered one to check it out - maybe it will be enough.
I'm thinking of ordering P2415Q or P2715Q from amazon to replace my glitchy U2413, but I will take a big risk as it will be an international order
On amazon there are a lot of bad reviews about the P2715Q quality, what do you guys think about that?
They say there are many color issues with the P2715Q, but since they share the same panel type / manufacturer, I'm not sure whether the P2715Q reviewers are just better at reviews, or the P2415Q is more robust

This doesn't sound right at all. Source?
The P2715Q looks great! If your needs include pulling out color calibration equipment, then you might want to stick with something else. If you're just looking for a generally great looking display, it's hard to beat (of course only time will tell how it holds up). Like any product, especially a new technology, there are defective units.
Yes, good idea. They ship with the Dells as well. And they're available at Amazon, Monoprice, Newegg, etc. - not hard to find, and less than $10.
The D300 works great with 4K displays.
Okay, it's completely understandable now that this thread is nearly a 1,000 posts long, but the last few pages of posts are mostly just rehashing what was already discussed and largely determined hundreds of posts ago. And of course the misinformation is starting to creep in. Beware.
