    I'm looking to buy 2 Dell U2718Q 4K monitors for my MB Pro 2017 15" 560, a brand new and gorgeous (very thin bezel) 4K monitor (this one). Anyone has already bought it and running on a new 2017 (or late 2016) MBP?

    I've read there were some problems with a 2015 MBP (see http://en.community.dell.com/support-forums/peripherals/f/3529/t/20017931) so I'm very curious if someone has it already running without problems. TIA for your response!!

    I would wait for a few weeks before buying. I am closely watching this monitor as well for the price-performance ratio seems rather high, like most Dell monitors they can usually be got at much lower than MSRP, and the U2718Q is available as low as ~$472 US where I am. But over at our local tech forums, at least 4 or 5 owners of this monitor have reported dead/bright pixels right in the middle, back bleed, uniformity, IPS glow, permanent blue lines etc, and theirs are all from the June batch. Looks like pretty poor QC was in place, probably why a pseudo-HDR 4K 27" monitor can be priced this cheaply.

    Thank you VERY much for this information, didn't knew that, checking stock here (Belgium, Europe) every day and it should be available next week (cheapest here will be around €800 initially, almost double of US!), but now I'm waiting a few weeks more, thanks again for the heads up!

    Three bits, from a longtime Dell/Mac owner. First, about that post it reads to me that the OP may not have the correct setup in the OSM - and it'll need to be set up for each interface. Second, the OP likely hasn't binned the cable that shipped with the Dell - none of their displays that I've purchased over the years are VESA-compliant; the correct DisplayID isn't negotiated between the PC/Mac and the display - it's not a "Mac thing" - and can be resolved by swapping out for a VESA-compliant cable from Accell/Belkin/StarTech/Eizo. Last, never buy a Dell display after it hits the market - the P2715Q display went through five revisions before they had decent build quality, and that includes the hardware in the display (sleep and freezing issues abound in early builds of Dell displays…).

    There's no way I'll buy a Dell until it's been updated a couple of times, just like I'll never buy a Mac until the kinks have been worked out…

    Any updates on this? I'm looking at this monitor myself but the color issues cause concern for me as a buyer. Wirecutter reported that Dell is working on a firmware fix for the color inaccuracies on Apple devices. Also I gather that the issues seem to be around displayport, correct? I *think* users connecting over HDMI are not having this color issue. Is this about right? Anyone using this monitor now with failure/success?

    I have been using it with a 2015 MacBook Pro with Iris Pro via HDMI. No problems, looks great.

    Thanks for the heads up, I was a bit afraid to buy after reading a few negative reviews and went for 2 Eizo 4K's, different price tag though but in 1 word perfect.

    maybe a little bit late, but I have this monitor and I'm using it with MBP 13" Early 2015 (mini display port to display port cable). What I can say is DON'T BUY, unless you don't care about colors also I have to use native 4k resolution because my MBP can't handle scaling, it becomes really laggy when I try to scale resolution. I've read about people using it with HDMI cable and reproducing good colors, but I haven't tryed it.

    If I had to make my decision now, I would not buy it.


    EDIT: colour problem is now fixed with firmware update (need windows pc to update monitor firmware or Parallels Desktop)

    Dear Miric, sorry to ask for clarification, but I do not fully understand what you wrote. Do you mean to say that Dell fixed the drivers, and that the colors now display correctly using the display port connection? Thanks in advance!

    Dear rulo. Recently Dell released a firmware update (m2b101 to m2b102, .exe file, though I run it in Win 7 on my Parallels Desktop without a problem) which is about that green color issue on Dell U2718Q through mDP/DP port. Now I find colors more accurate.

    The HDR option has always been disabled, even before the firmware update. Dell advertised this monitor with its HDR ability only available through HDMI.

    But yeah glad that they did fix the green color issue. Though with the new HDR400/600 standards coming along, this monitor, along with those few that were also released as pseudo-HDR (not reaching 1000nits) will probably be phased out.

    Glad to know one more happy user of this display. Though I'm still waiting for my Plugable USB-C to HDMI 2.0 cable to decide: DP or HDMI.

    By the way. Did anybody have success to get HiDPI on resolutions lower than 3840x2160 (besides 1920x1080). I was playing with two Mac minis (MD388 and MGEN2), via DP and HDMI. Tested El Capitan, Sierra and High Sierra. No result. I don't have scaling option buttons as well as I saw '(low resolution)' near each resolution line below 4K. It seem both Intel HD 4000 and Iris 5100 are not capable of rendering HiDPI image larger than 1920x1080 meanwhile Intel Iris 6100 on MBP 13" Early 2015 is.

    A family member who does editing all day is considering one of their ColorEdge models because of the insanely positive reviews. Obviously, they are insanely more expensive than most other 4k offerings. Looking back on your purchase, do you feel it was a good value for what you got and how you intend to use it?

    Hey guys,

    so I actually just got the Dell instead of the LG because 500 EUR vs 1.4k and better reviews/build quality seems like the way to go.

    I connected it via USB-C to DispayPort. Is there any better way to connect it in order to have better picture quality? Also, what are the optimal settings for the Dell in combination with my iMac 2017 5k model?

    Other than that, is there an option to let the Dell auto shut down whenever the iMac goes into sleep mode and auto turn on whenever it wakes up?

    Normally, DisplayPort is the best connection when the concurrent generation of HDMI version on devices is usually slightly inferior. But for this U2718Q in particular it does not matter, its maximum specs are covered by both DP and HDMI capabilities of the 2017 iMac (or more specifically, the TB3 standard).

    However, as noted, this monitor suffers some issues with green color via DisplayPort but not via HDMI. And then the HDR feature is only possible via HDMI as well. macOS and some apps do support HDR and it will be more commonplace, if you for instance view HDR videos on the iMac then the HDR is disabled when outputting through to DP monitors, but it supported on HDMI and the internal display as well.

    I don't own this monitor but I got other Dells, on both my UP2716D and U2414H, the default power saving settings already put the display to sleep whenever the host Macs themselves are slept. I believe there is a 30 seconds or a few minute timeout count down.

    I already noticed that the left part of the monitor is much more "yellow" then the rest. Perhaps because it's a used one for a discounted price. I read somewhere that I should check for "A00" through A03", as that indicated when the monitor was build and it's quality. Do you know what exactly that means?

    By using HDMI instead of DisplayPort, should I pay attention to specs of that USB-C to HDMI cable or is any with decent reviews from amazon good to go?

    As for the sleep mode of the Dell, it does go into it, but the white light is still on, at the bottom right. That seems like standard stand-by mode, right? In that case I should turn it off manually, just to save the energy the monitor would waste if I am away for a few days for example. Doesn't the LG 5k completely shut down if the iMac/MCB goes into sleep mode?

    I am receiving Spyder 5 tomorrow and will calibrate both, the iMac and the Dell and let you guys know how I like it. So far, the Dell is fine, but obviously I much rather prefer to work on the iMac and therefore really need to think twice about keeping it.

    The factory condition should already got a calibration for uniformity, and by default the "uniformity compensation" feature should already be on, unless you switch to CAL or ICC profile modes I believe. You should go into the Dell's on-screen-display menu to locate this option and confirm. This in theory should root out partially tinted and/or darkened areas of the panel by a large amount. If you are still seeing locally yellowed areas no matter what setting, then it is a lemon (probably why it is discounted I guess). It all depends on how you use the display and if you accept the amount of tint, for instance if you color correct photos/videos which frequent have grey / white scenes then it is definitely not acceptable, but if it is just a media consumption display then you may let it pass.

    I haven't followed which specific batch number of the "make" is better than the rest, since I don't own one (I only considered). AFAIK, the earliest June-August batches had obvious issues, where the Nov batch had some issues resolved or have better QA. But these are just what I gathered from all over other display forums on the internet.

    I think for 4k 60Hz, the USB-C has to specifically states it supports HDMI 2.0 version, if it is ver. 1.4 or lower then the output is limited to 30Hz on the U2718Q. I myself didn't buy any such dedicated display dongles, as my OWC TB3 dock has mDP port, and then a G-RAID has HDMI 2.0 on it, so I am covered even for a tri-monitor setup for my iMac 2017. But I think 4k through to HDMI is now such a frequently requested feature, and the USB-C situation is better now than say a year ago, most of the newer dongles should serve this well.

    Stand-by mode is exactly what (I thought) you looked for, backlight panel + LCD screen is off, but the mainboard of the display stays on always waiting for the computer to wake it up. I don't think the energy savings by totally powering it off is significant enough to warrant the hassle, but if you are offsite for a long time then powering off is probably for the best in terms of household safety. I don't think any monitors out there would shut itself completely whilst in standby mode nowadays, otherwise it would take an unacceptably long time to wake/re-sync from the source, by today's standard.

    The Spyder will help if color is a concern in your workflow. But you may already know it, then the U2718Q doesn't cover as much color gamut as the iMac's P3. So if you got a wide color image such as a DSLR RAW, using software that supports wide gamut ICC like Lightroom, then you definitely are going to see more colors on the iMac screen than the Dell. I believe even the Dell HDR or whatever they call it won't beat the iMac screen either, since it has lesser peak cd/m2 on paper.

    Can anyone here confirm that with U2718Q Macos Sierra uses the tiniest-scaled resolution as `Default for display`? I also have a U2414Q, and it defaults to a sane DPI. Is there a particular reason for that?

    I have USB-C to DP from j5 create cable with updated monitor firmware but decided to buy Plugable USB-C to HDMI 2.0 to compare and make a decision to stick with. Need one for coding in an office and another for converting photos at home. So the second use case is more demanding in terms of image quality. Can't make any conclusions for the moment because still didn't get Plugable cable.

    Which Mac do you use to connect Dell? Maybe you mentioned it but I'm lazy to read. I had some experiments with Mac minis 2012 and 2014 with 10.11/12/13 and yes all the time U2718Q was at 3840x2160 with tiny elements/symbols as default for the display. No way to get HiDPI picture unless 1920x1080. Rest of upper resolutions are fuzzy. :(
