ORDERED the P2715Q from Dell

I just bit the bullet and paid ~$539 out the door at dell.com for the P2715Q, to match it up with my LG 34UM95 3440x1440 monitor.

Going to be interesting to see if it can drive both monitors at 60Hz.....

Should be an interesting combo. :) :D:cool::apple:

Have anyone tried using a standard 1080p or 1440p input and let the display upscale it to 4K. How would the quality of this be compared to using a 1440p monitor?

The issue is that i need a monitor now. I dont expect my current setup (late11 macbook air) being able to handle 4K. Hence, it would make sense for me to just buy the U2515H (1440p) which is about half the price of P2715Q. However, as I will properly udgrade my setup within the next 6-12 months. I'm thinking it would be stupid of me not to buy a 4K display.

if thats the case just buy a 4k now, unless you want to buy another monitor down the road.

depends on which 1440p monitor you referring to, on paper it matches or exceeds all monitors in terms of picture quality with exception of 10 bit professional monitor and 1ms tn gaming monitors for input lag and response time.
 
I may have a lemon. I just got the P2715Q, plugged it into a late 2013 Mac Pro with the included cable and... nothing. Darkness. None of the display buttons work.

Eventually the display will try to go into power saving mode, whereupon it will respond to the menu button--but only to give a choice of inputs. The manual indicated a shortcut to force the display to secondary MST mode by holding down the selection button for 8 seconds. When I did this the display started working, but only at 30Hz.

The panel is gorgeous, but the firmware / sleep / SST MST issues are a showstopper.

I'm running Yosemite. The Dell is connected to the only Thunderbolt port in use. I've tried switching ports. I cannot get this monitor to run at 60Hz.

Anyone have any theories? I will try an SMC reset and hard power cycling everything.

Edit: The included Dell DisplayPort cable was bad.

I have a nMP running Mavericks. Just got the P2715 yesterday and had similar problem.

The display cable should be connected to the socket right behind the mount post, not the one offset (at least this is where I connected the cable and got the monitor to work). The input needs to be set to DP. I replugged the display cable into the nMB and the P2715 was recognized and runs at 60Hz.

I must say this monitor is a step up over the Apple Thunderbolt monitor. They are both side by side and the P2715 is significantly sharper and easier on the eyes, text is outstanding!!
 
Im wondering too if I should just get the new BenQ SW2401PT with 99% AdobeRGB for my photo editing or the Dell P2415Q/P2715Q. Which of these monitor will offer the sharpest fonts for reading long documents as well as editing photos?

The monitor will be connected to a late 2013 retina macbook pro in clamshell mode.

thank you
 
Ordered a second for home, and thought I'd get the same deal of $175 off, but it ended before the web sale ad deadline of 8am EST. Complained by chat to customer service and got a quote for a sale price of $449! Something to try, YMMV.

That's a good point, but I already had it in the correct port. After your comment I decided to try it in the wrong port just for variety's sake. Same behavior. (Also, it's really nice of Dell to label the ports on the monitor. /s)

I also did an SMC reset.

Given that others say they plug it into the Mac Pro and it "just works," I think I may have to RMA this monitor. I may try buying a high-quality DP-to-mini-DP cable locally to see if it's just the included cable.

Despite the quality of the screen, if it's not the cable, I hesitate to exchange the monitor. I may just refund it. The DP issues and craptacular menu system scare me. The monitor should never leave the user wondering if it's dead, even if it isn't connected to a computer. I think this is just shoddy firmware on Dell's part.

I did this on one of mine too, plugged it into the wrong Display Port connector, and it was blank. Freaked me out a bit :)

You should also read up on the way the TB ports are layed out on the new mac pro, and ensure you have your displays on different busses. There's an Apple page showing the layout. Basically, the left top 2 ports are one one bus, the right top 2 ports are on another bus, and the 2 bottom ports are on the third bus, which shares the HDMI port.

Sounds like you might have a problem with your unit. The included cables are working great for me.

After a week with mine I have yet to have any issues waking from sleep and just working.
 
Hooked up my P2715Q today to my rMBP 15", working very well, looks 'retina' to me!

Can't seem to get the USB hub to work though, it will work with the laptop open, but my mouse is rather jerky. Doesn't work at all when laptop lid is closed, USB on monitor menu is greyed out. Getting another one of these monitors next week, so I will check that one out and see what gives. May have to just get an external USB 3.0 hub...

I think it's a universal issue with Dell monitors and Apple products. I've read reports elsewhere that other Dell screens USB hub function flat out didn't work or has issues like you've described.

usb on my monitor is greyed out as well, but the ports all work just fine. i do have the occasional sleep/wake issue though. using this with a mac mini as well as a 13"macbook pro.
 
It concerns me that people are buying these monitors and they are not fully compatible with the Mac. No boot screen, wake/sleep issues and OSX does not fully support full 4k.

Why do you continue to say this? I have FOUR Macs, two desktop Pros and two laptops. I can run any of them on these monitors, the desktops full rez and the laptops nicely scaled. Drivers are still in dev...for OS X anyway, but are largely there. They are already flawless in Win via BC, by the way, except for scaling the options (not many at all). Not everyone experiences a wake/sleep issue, which is not confined to this monitor, or any other component for that matter, e.g., some external drives. I've had the issue only twice, and it is easily remedied by turning the monitor off, i/o long (overnight) sleep. Many have had success by disabling a setting in the monitor to get rid wake from sleep issue as well.

What do you mean by "full" 4K? The monitor and TV makers have latched onto 4K as a marketing term when it actually is only accurately applied to DCI 4K (4096x2160) which is a video ACQUISITION format found only in pro/prosumer video cams, and, as of now TWO displays. It is always intended to be cropped, sometimes severely so, prior to delivery of the output. DCI 4K is not intended for anyone on this board unless they are pros shooting 4K and planning to crop to 2.39 or 1.85 aspect for projection.

These Dell monitors are UHD (3840x2160), which is every bit as valid a rez as DCI 4K. But, I give up - unless otherwise stated, I'll use them interchangeably below. 4K (UHD) is a quadrupling of "full HD 1080p," another marketing moniker and is the broadcast standard for "4K" content now on Netflix, Amazon, etc., and forthcoming 4K BR. These Dells, assuming you have the GPU and updated OS/drivers for them, push out pristine UHD SST at 60 Hz, and a multitude of scaled refs yielding razor sharp text like you've never seen before.

People complaining about about not getting 60 Hz. simply are trying to get it with outdated or underpowered equipment, the wrong cable, an outdated OS or drivers, or operator error, or a combo thereof. As I said, there are a few quirks on occasion, but this comes with early adoption. I've had numerous conversations with Apple about current support, and what they are doing to iron out any remaining bugs, which are few.

Meanwhile many of us are quite happily enjoying four times the resolution of 1080p and some of us, including me, are wowing clients with the results and making good money at it. The transition to high def 12 years ago was far more painful now that I've had time to think about it, than this move to 4K/UHD. Contrary to my first impression, I now recall it took three years to get a hardware/software workflow that worked. This transition took, oh, two weeks tops, and I'm running over 95% problem free - maybe better than that.
 
Why do you continue to say this?

Well said xav8tor.

The P2715Q works really well here with my nMP and a very worthwhile update from my Apple 30" Cinema Display.

No problems whatsoever and a second one is on it's way.

Rather silly of you to be "concerned" Michaelgtrusa, get some perspective here. Sheesh.
 
Just picked up my 3rd P2715Q on this last promo! Everything works great!

I no longer have the issue with the login screen not showing up now that I am required to have one of my monitors plugged via HDMI. The login screen comes in fine because the OS recognizes the HDMI monitor prior to loading the OS.

Haven't had a single wake issue once I switch the DDC/CI to disabled!

DP monitors are left and right running at 60Hz. Center monitor HDMI at 30Hz.

WHY!? My money is being asked for by these companies for a monitors that OSX full support for seems half baked, perhaps you should reread the whole thread and my last post and then maybe, you comprehend by concerns as best you can.

You don't understand what full 4k is? Google search it. If the drivers are still in dev the why sell it for Mac users?! Since this is an open forum anyone has the right to keep asking a basic question, that some are more than happy to answer with out being bothered to much. Why is that a problem for you that I as others are concerned?? I'm doing that same research as others here and don't want the same issue others are have encountered.

Wouldn't anyone be concerned if looking for a gull 4k monitor?! I express my concern over the problems that people are having here and this is your reply. Perhaps never reply to me on this thread again. I certainly have the right "attitude toward or way of regarding something"

The problems are minor and can be fixed with software. They aren't a fault of this panel.

It's a great looking display at an amazing price. I'm pleased.

My usb hub is working fine with my nMP.

I'll reply if I want to, I don't need your approval to do so, thanks though.

Your attitude is rather overblown and silly.

Me, I saw there was nothing to be "concerned" about and just bought two.

Anyone with a nMP will be fine running these, image quality is well worth the price.

My reading comprehension is fine. With two related grad degrees with a 4.0, at least I hope so. I've read the entire thread since inception, some of it three or four times, and have participated heavily in it. No, I am not concerned because I am not looking for a "gull" or a full 4K monitor and no one, including Dell, despite the intermittent use of "4K" is, in the fine print anyway, claiming this is anything other than a UHD (3840x2160) display. Google 4K? LOL! Since part of my biz involves shooting video, now 4K, I assure you, after over three decades in various audiovisual fields, I have intimate knowledge of what 4K is and isn't. The vast majority of the public hasn't a clue, and quite apparently, neither do the manufacturers, not to mention many people buying them. Alternatively, they (both TV and monitor sellers) are taking advantage of you by deceptive marketing (e.g., "true 4K"). There's a surprise.

As I said, 4K is a misnomer and should only be used in reference to a DCI standard, which I seriously doubt anyone here uses. Half-baked? Uh, how about well aged, nicely trimmed, but ever so slightly underdone. Flawless? What is? It sure ain't the new Mac Pro or Yosemite. Pick any 100 new high tech components and find 95 that work absolutely perfectly when mated to other components. You can't. It doesn't happen with airplanes, medical devices, or home appliances etc. either. These particular displays, especially for the $$$, are great, all things considered.

I initially complained about scaling (operator error on my part), warm tint on part of the screen (fixed with a bit of calibration), and the sleep issue (remedied with two or three presses of a menu button). Other than an occasional and brief flicker lasting a nanosecond (new driver to fix that coming), it's now perfect. Just got my first check for a 4K project using this monitor for grading and preview. It paid for itself about thirty times over. Now I am using it for free...pure profit except for a few bucks a month for power.

When you actually get one of these and use it professionally after weeks of testing and months of research, come back and argue with some substance instead of conjecture, if not paranoia. Until then, negatively opine on while the rest of us ride the wave of the cutting edge, doing things others cannot fathom until they actually see it.

PS- If you want a "full 4K" monitor, try LG or Eizo. They make the only two on the market, but like I said, they are not intended for general consumption. Read THEIR adverts, and you'll see both are aimed at pro video users of 4K footage. With Dell's return policy, why not try one out instead of flaming a product you don't own, use, and probably have never laid eyes on? People post on these forums often to resolve perceived, or real, problems. For every one of those, there are probably a hundred happy users who do not post and/or have never even heard of MR. Check out some pro vid forums and see what is being said about these products. Are they as good as a newer 2,500 USD reference monitor? No. Do they give 97% of the performance for 20 to 25% of the cost? Yes.

PS - As for those Apple "approved" displays, do you have a clue how many of those are full of far worse problems than you've read here? Pretty much all of them.

TLDR: Whatever.

Ok, that's officially ridiculous! :p

What resolution is your desktop? Do you notice a big difference at 30Hz? How would you characterize it?

It concerns me that people are buying these monitors and they are not fully compatible with the Mac. No boot screen, wake/sleep issues and OSX does not fully support full 4k.


Thanks for your concern, but living on the bleeding edge of tech is a conscious decision that I've made that often comes with a few compromises and some nice rewards. As long as you know what the trade-offs are (which this thread dutifully provides), there's no need for concern. Don't stress too much over what we're doing here, most of us are having a blast ;)
 
I may have a lemon. I just got the P2715Q, plugged it into a late 2013 Mac Pro with the included cable and... nothing. Darkness. None of the display buttons work.

Eventually the display will try to go into power saving mode, whereupon it will respond to the menu button--but only to give a choice of inputs. The manual indicated a shortcut to force the display to secondary MST mode by holding down the selection button for 8 seconds. When I did this the display started working, but only at 30Hz.

The panel is gorgeous, but the firmware / sleep / SST MST issues are a showstopper.

I'm running Yosemite. The Dell is connected to the only Thunderbolt port in use. I've tried switching ports. I cannot get this monitor to run at 60Hz.

Anyone have any theories? I will try an SMC reset and hard power cycling everything.
It happened EXACTLY THE SAME to me with the p2415q and my brand new mac mini, using the provided cable.
Works fine with HDMI and, right now, is working at 4k 52hz via dp (with a mDP to mDP cable that I bought, and after getting nuts trying and trying). It is everything strange...looks like if the drivers were not completely checked for some setups...If you read my previous posts you will notice. Right now, the mac only starts the screen via dp if the hdmi is plugged in too...otherwise, after the login, my screen keeps black forever...Not sure if it is something with the mac drivers (I think so) or with the screen, will try to check in the future the screen with another computer.
Appart from that, I am really happy with this screen, amazing image quality! The only issue right now, appart from having one unused hdmi cable there, is that sometimes the screen doesn't wake up after sleeping...
On the other hand, I've just tried the provided cable in another monitor and computer and it works perfectly...

I took some photos of the new monitors.

These were taken with the system running at full resolution, 60Hz, scaled to "look like" 2550x1440.

The images were shot with a Canon 5D3 with a 24-70 II F2.8L lens and a 100mm F2.8 L Macro lens . The macro shots show you what things look like up close, and you can compare with the shots further out to see what sort of scale we are talking about here.

There's a couple of dust specs in the macro shots, they are not dead pixels :)

These are mounted on Human Scale M8 arms.

A wonderful dream set up. Did you resolve the boot screen issues?
 
A wonderful dream set up. Did you resolve the boot screen issues?

The workaround for now is to use the HDMI port of the Mac Pro, and switch to that input. And, honestly, I don't even do that. I reboot my Mac Pro infrequently (every few weeks), so I just wait 30 seconds after the "bong!" sound, then type my password in blindly.

The long term solution is an EFI update from Apple. This doesn't affect just the Dell display, it's any 4K SST display. From what I gather, even the LG display listed on Apple's website as "supported" has this issue as well.
