Has anyone else tried the Dell UP2715K 5K monitor?
I have a 2016 Macbook Pro 15" with the AMD 460, and I can't seem to get it to work. I ordered a couple of USB-C to displayport adapters and it works fine in single stream and I can show 4K without issue. However it will not give me an option or even recognize the second adapter/cable so there is no way to get 5K to work.
Any ideas?
Thank you!
I’m a bit late to the party, but the following information might still be useful for some people:
I had the chance to connect a Dell UP2715K and an HP Z27q to my 13″ MacBook Pro with Touch Bar (running macOS 10.12.4) today. Both worked without any problems at the full resolution of 5,120 × 2,880 pixels at 60 Hz, using two USB-C to (Mini) DisplayPort adapters. (Admittedly, my test lasted only several minutes.) No issues, no need to fiddle with SwitchResX, no matter whether I used the ports on the MacBook Pro’s left or right side.

The Dell UP2715K comes equipped with three ports: two full-size DisplayPorts and one Mini DisplayPort. For 5K, you need to use both full-size DisplayPorts, while for 4K you need to use the single Mini DisplayPort. (See the user manual, p. 11.)I was going to just run in 4K off one USB-C to DP cable into the first DP port on the Dell that is marked blue (assuming that works? I haven't yet tested)
So I'm very curious if it works with the Dell in 4K with only one cable (and how it looks), as well as now the two cables which you say works. Thanks for this info!

Using only one of the full-size DisplayPorts will work, too, but the resolution will max out at 2,560 × 1,440 pixels, in my experience.
4K looks fine, I would say, but—due to the interpolation involved—nowhere as razor-sharp as 5K.
In addition, you have to tell the screen via the on-screen menu which input(s) to use. The screen is “too dumb” to detect by itself which input(s) is (are) are being used.
Regarding the USB-C to (Mini) DisplayPort adapters or cables, make sure that they support 4K at 60 Hz. Some support 4K only at 30 Hz.

...PS I am on macOS Sierra 10.12.4, and the fans run somewhat hard even while doing nothing. Not sure if that is because of monitor or something else...
Hi all in the thread... I'm especially interested in Holger G. and Anticipate's posts because...
I have a Dell UP2715K.
I'm considering buying a brand new 13″ MacBook Pro (2017) with Touch Bar (top end spec). I need to run the monitor at the full resolution of 5,120 × 2,880 pixels at 60 Hz.
According to Holger's post, he achieved this using two USB-C to (Mini) DisplayPort adapters.
So....
(1) Could it be confirmed this config is sustainable and works well for the 13" Macbook Pro?
(2) If so, which specific USB-C to DP cables / adaptors were used?
I'd rather buy a 13" Macbook Pro if possible, but might need to upgrade to a 15" if necessary?
Thanks for your help - its my first post here!

(1) Yes. That’s why I posted the image in my post.
I also tested my (late-2016) 13″ MacBook Pro with an HP Z27q display, and it worked equally well.
On my MBP, the two Thunderbolt 3 ports closer to the front have a noticeably tighter fit than the two closer to the back. This is why I use the ones closer to the back almost exclusively for power supply. When using the ports closer to the back, I could produce a flickering image with the adapters mentioned below by moving them slightly inside the ports—which didn’t happen with the two ports closer to the front. This means, of course, that you have to use ports on both sides of your MBP simultaneously.
(2) I bought one USB-C–to–DisplayPort adapter (from Club 3D) and one USB-C–to–Mini-DisplayPort adapter (from Benfei). I used these adapters with one of the DP-DP cables and one of the mDP-DP cables that were included with the UP2715K. In your case, I would probably go with two black USB-C–to–DisplayPort adapters (from Club 3D) for aesthetic reasons.
As I mentioned previously, you have to make sure that the adapters support 4K at 60 Hz. If you keep that in mind, I’m sure that also a direct USB-C–to–DisplayPort cable (like https://store.google.com/product/usb_type_c_to_displayport_cable) would work.
By the way, if you’d like to occupy only one of your MBP’s Thunderbolt 3 ports instead of two, have a look at https://www.sonnettech.com/product/thunderbolt3-dual-displayport-adapter.html and https://www.startech.com/AV/Converters/Video/thunderbolt-3-to-dual-displayport~TB32DP2T (for a Mac, it has to be the TB32DP2T model—not TB32DP2).
Some great information there Holger. Thank you for taking your valuable time and consideration to respond to me on here.
I have been able to get the Dell UP2715K monitor working well at full 5K resolution / 60Hz with my newMacBook Pro 15 2017

HOWEVER... IMPORTANT CABLE SELECTION:
I originally bought the USB-C <> DisplayPort adapters suggested (The Club 3D ones, model CAC-1507). When I attempted to use these, I got NO RESPONSE from the Dell monitor except it reporting "Entering Powersave mode", and reporting there was no signal coming from my computer... Then entering powersave mode... I tried different variations of ports (including one cable only) but could achieve nothing![]()
.
I wondered if it was a cable issue, as I have read there is variation with the 2017 models of the MacBook Pro, and most cables will not work. Therefore, I decided to take a chance and buy two of the following USB-C <> DisplayPort cables (not adapters) from ChoeTech:
https://www.amazon.co.uk/gp/product/B0744GWJ8X/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
They arrived Today. I plugged them in (both in rear USB-C ports). Straight away, they were detected and I am able to use the monitor as an external Retina display at 5K / 60Hz. No other config or SwitchResX required. The cables are well built, and in the UK (Amazon) are currently reduced from £29.99 to £11.99!
The UP2715K has been working seamlessly for hours now, and looks fantastic. I am using it now. Fingers crossed, this continues!
Also, I deselected the system preferences > Energy Saver > Automatic graphics switching option. This is because I read on another post that this may help. N.B. I had done this with the original cables too, but it had no effect.
For reference, MacBook pro 2017 is the touchbar version, with Radeon Pro 560 4GB graphics card (16GB RAM).
I hope this helps others who are trying to get their MacBook Pros working...
Many thanks for keeping us in the picture on this Anticipate... It's a bit worrying if High Sierra has broken things!
It would be great if you could you keep us updated with any further info on this if possible? Probably best not to upgrade until it get fixed!
...EDIT! ---- Just seen your update that it is working in High Sierra beta... Phew!
Thank you again for the updates
Thanks! Good to know. Much appreciated. Very helpful!!
I have two "Plugable" USB-C to DP cables that I will try tonight. They explicitly state they support 4K at 60Hz. I will update after the test.
Hi all --
Wanted to throw in my $.02. I purchased the monitor today and was able to run full 5k on the display with my 2017 MBP 15". I connected two DP cables from the monitor to a Sonnet Thunderbolt 3 to Dual DisplayPort Adapter, then wired that to a single Thunderbolt 3 port on the laptop. The display is gorgeous and works flawlessly. You'll need to have the power adapter plugged in to the laptop to get the monitor to stay on while the computer is in "closed-lid" mode.
Cheers.
Hi timo, I am not running a MBP 2016 or later, so I can not provide detailed answers for your specific setup. Although I have a Dell UP 2715k connected to a Mac Pro 6,1 and sometimes a MBP Mid 2015 (Radeon M370X) - When connected via Dual cable I get native 5120*2880 resolution on both machines. Scaled HiDPI Resolutions (for bigger text) are always available. This is even, when monitor would be running in 3840*2160 only. So there is no direct relation between full resolution support and text scaling in the first plays. Anyhow both should be provided und supported with your combination.Hello arijon and others, who have tried to solve the 5k-problem with the Sonnet Thunderbolt 3 to Dual DisplayPort Adapter!
I think about buying this adapter, because I have already tried the solution of wodge with the ChoeTech cables. I only get 4k (60 Hz) with one cable. The second cable has no effect, no matter which port I use (MacBook 15" 2017, Radeon Pro 560 4GB graphics card (16GB RAM)).
My question: Is it possible to scale to larger text, like in the screenshot of Holger with his solution? If it's not possible, the Sonnet isn't a choice for me, because it's too hard to read the letters. I already have some problems with the size of the letters in 4K and can't scale it.
Who have tried the Sonnet Thunderbolt 3 to Dual DisplayPort Adapter on a new MacBook and is able to scale the text?
Thanks for your help.

Hi timo_k82,
Yes you can absolutely scale up and down with this arrangement. And an important point to note though is that on a Retina 5K screen you will have a 5120x2880 native resolution, but by default run "pixel doubled" at a setting that looks like 2560x1440, it just has four times the detail of a "traditional" display.
Cheers~
That's normal and fine!Hello arijon, wodge, Halbertus and the others!
Maybe anyone can help me to find out, if it's normal that the resolution in the System report is smaller than the native resolution of the monitor.
I can not think of a reasoning why this should not work by specifications. Thunderbolt 3 chipset of the MBP is capable of Dual DP 1.2 on each Port.Hi everyone,
Do you think that the 15" MBP will run DUAL 5k Dell UP2715K Monitors at the same time, using 2 Sonnet Thunderbolt 3 to Dual DisplayPort Adapter plugged in two TB3 ports?
