I am now testing with nothing else connected. Both cables for UP2715K #1 are connected to Bus 0. That works fine.
UP2715K #2 is connected one cable to each of the other 2 Thunderbolt buses. It is better than before, so far, but still a little glitchy. 60Hz testing fails. Sometimes there are graphical anomalies, particularly if you move a window from the primary display. The slight progress is encouraging, though.
 
What are you getting at - was Apple not first out of the gate with a 5K display in their iMac for the consumer? Because someone does something successful, no one else should follow? Good luck with that.

That's like saying "because technology was progressed by someone else no one else should follow." Because of the positive reaction towards Apple's Retina iMac Dell "realized" people appreciate that technology. So what, they shouldn't have done anything with it because Apple did it first? I don't quite get the point of your post.


Sorry if I'm misinterpreting your post, but if not

There are PC forums out there you know...

Just ignore that guy, all he does is spread FUD and negativity on here.

Wait.... You connected 2 UP2715k and both work, the first on 60Hz flawlessly but the second ? What is the frequency there ? No 60Hz but ... ? 30Hz ? 50Hz ?

I theory I would say the nMP should be capable to run 2x 5k / 50Hz each and 1x 5k / 30Hz.
I am running 1x 4k + 1x5k = both at 60Hz flawlessly.

If 1 card is capable to run 5k / 60Hz two cards should be capable to run 2x 5k / 60Hz... right ?

Only one card is running displays. Other one is compute only. Whether this could be changed, I don´t know.

So, you are running UP2715k@4K@60Hz ? MiniDP or HDMI ? SwitchResX or natively ?

Really ? Are you sure ?

Well, I´running 2 displays:
UP2715k@5K@60Hz
PA322UHD@4k@60Hz

Both together running perfectly.
 
I am not interested in plain 5K displays. I will buy a 4K 3D display then.
 
Here's the block diagram for the nMP that shows how the display ports are connected internally...

Perhaps it is a hint for an upcoming update to the nMP itself? :rolleyes:
 
The number of 5K monitors on the nMP with a D700 should be theoretically similar to this chart (which is outdated since we know the nMP does support more than 1 SST 60Hz 4k monitor):

Where is this diagram from ? High-Res of that picture would be appreciated.

Well then... I´m surprised. Doesn´t seem to be the best design possible. Anyway I´m satisfied.

That's all we've got. Source unknown. System Info will also tell you which GPU your displays are connected to. And it's consistent. There's no reason to believe this is not official or at least accurate.

Oh yes, I believe. Just interested in all those details, not just the GPU ports.
 
I think it's pretty obvious that Apple will be building a 4k and 5k stand-alone displays at some point, I cannot think of one reason why they wouldn't. This is interesting, I suppose at 30 Hz it would be possible...not pretty though.

UHD (3840x2160) at 60hz is possible with a single mDP 1.2 cable. Would love an updated UHD 27" thunderbolt display
 
I need some advice: I have the nMP with the D700s, and currently I am running two Apple displays of it. A Thunderbolt Display connected to TB port 1, and a Cinema Display connected to TB port 2. I also have a Lexar Card Reader box on TB port 3, an external Sonnet PCIe housing connected to TB port 5, and an external LaCie SSD to TB port 6.

If I added a Dell UP2715K to the mix, and still wanted to run both Apple displays, how would I hook it up, wanting of course 60Hz on the Dell?

I am thinking:

The Dell on TB ports 1 and 3, the Apple Thunderbolt Display on TB port 2, the LaCie SSD to TB port 4, the Apple Cinema Display on TB port 5, and the Sonnet PCIe box to TB port 6. The Lexar Card Reader box I would have to piggyback of one of the displays...

Hmmm.. Wow...

My personal idea: Bus 1(or 2) for Dell and Bus 2(or 1) for both Apple displays, should work fine.
SSD + Sonnet to 5/6. And yes, the card reader can be placed somewhere else.

What card do you use with your PCIe Box ?

All that stuff might be a bit too demanding in the end.... ??
 
Tanks for your input. If I remember right, TB bus 0 are ports 5 and 6 plus HDMI, TB bus 1 are ports 1 and 3, and TB bus 2 are ports 2 and 4...

In my Sonnet PCIe box I have two cards, a 1TB Accelsior and a Sonnet Tempo Pro (w. 2x500GB Samsung SSDs). I use the fast storage for photography applications, like Photoshop, Lightroom, and scratch storage in general...
