Hello,
 
I recently purchased a Macbook Pro and am looking to connect two additional monitors to a single mini display port. I only have 2 ports in total and the ethernet adapter requires one of them. In this instance wireless will not work and I need more speed than a standard USB-Ethernet adapter. Altogether, I have two 1920x1080 monitors that I want to use in conjunction with my retina display and I was wondering a few things specific to the DisplayPort hub. 
 
1. Probably a stupid question, but I'm assuming that this is compatible with a Mac/OS X?
2. I will need to have an odd setup where my Mac is mini display and the monitors are DVI. In terms of setup I'm envisioning something like this:
 
mini display to display cable -> hub -> 2x display to DVI cables -> monitor
 
Hopefully others can share their thoughts or maybe an EVGA team member that is knowledgable about the product. I look forward to your response, thanks!

    Yes, you can connect DVI monitors, but you need to use active DP-to-DVI adapters.

    Hi Erin,
     
    Thanks for that tidbit! It looks like the original monoprice cables I was planning to buy are passive cables. Time to go find something else.
     
    Thanks!

    So... After all is said and done, I cannot get this to do anything but mirror the attached displays (2x Dell 1680x1050 resolution monitors). Here are the associated cables that I purchased, the DP to DVI are active adapters.
     
    1x Mini DisplayPort to DisplayPort, 3 ft cable:
    http://www.monoprice.com/Product?c_id=102&cp_id=10246&cs_id=1024606&p_id=6006&seq=1&format=2
     
    2x DisplayPort to DVI (Active) - $24.99:
    http://www.amazon.com/Cable-Matters-Plated-DisplayPort-Adapter/dp/B00EDT01TO/ref=sr_1_1?ie=UTF8&qid=1404069218&sr=8-1&keywords=displayport+to+dvi+active
     
    When plugging in the DP hub, the the hub ports light up properly where the monitors are plugged in. I've tried both ports 1&2 and 1&3 with no difference in the end. I have a MBP 15" Retina model and the mini display ports are thunderbolt 2, so they should be able to handle whatever resolution.
     
    Any ideas from the EVGA folks why this might not work?
     
    Thanks.

    Strange, the Thunderbolt ports are DP 1.2, and should work just fine. Are you running Mavericks on your MBP? Also, do you have BootCamp installed and can boot into Win 7 or 8?

    Re: DisplayPort Hub Compatibility 2014/06/30 12:41:41 (permalink)
    I am using Mavericks on the MBP and I spoke with a buddy that has a DP hub on his laptop dock and he's running Windows. When we plugged the EVGA hub into this, an Intel window popped displaying all the monitors up so I'm wondering (being that the default graphics chip is Intel), that I need to be running Windows to make this work. Although, this didn't work as well, but I think it was because of the native DP hub that the EVGA DP hub was plugged into. I think with my current setup and Windows, this would work. Unfortunately, this is not going to be feasible because I need to be running OS X or Linux.
     
    I found this article written earlier this month and I'm wondering if it's just that the Linux kernel doesn't support DP Multi-Stream Transport yet. Apparently this is scheduled for the 3.17 kernel.

    This doesn't do me any good now, so I'm hoping that Newegg will accept the return.

    Are you running the 10.9.3 or 10.9.4 update on your MBP? From the notes that I've seen, it should improve displayport support in Mavericks.

    Has there been any traction on this?  I'm just about to do the same thing with a 2014 Macbook Air + EVGA, with two differences:
     
    1. One monitor is a DELL with a displayport jack. So, thankfully, no adapters necessary for this monitor.
    2. I will be getting this ATI-certified active DP->DVI adapter: 
     
    I'll let you know how it goes.
     
    Does EVGA have a DP->DVI adapter recommendation?
     
    Being that the OP has not replied, I would guess that s/he's been successful.  If so please share, or let us know if you've returned it all.
     
    Thanks!

    Bottom line is that it doesn't work on my 2013 MBP or any MBP for that matter (right now at least), all you will receive is mirrored output and the OS will only detect one monitor. It does work on Windows because of the native Intel graphics application and it's ability to support MST (outlined below), when the device is plugged in it pops up and displays all attached monitors properly. I purchased the device and now have a $100 paperweight.. yes I do have proper active adapters and I was able to confirm by testing them in a Windows configuration.
     
    After doing a bit of research, I realized that the Linux kernel does not yet support Multi-Stream Transport (MST) which is what's used to differentiate the signals to different screens. This has been slated for mainstream 3.17 kernel. So until then, it will not work with any Linux/Unix based kernel lower than this version, unless you manually build in MST support. Here's a few articles about MST and the kernel published earlier this year.
     
    http://www.phoronix.com/scan.php?page=news_item&px=MTcxMjI [June 2014]
    http://www.phoronix.com/scan.php?page=news_item&px=MTY1MjI [April 2014]
     
    This line pretty much sums it up:
    "Right now trying to use MST will just yield a single-stream and the same image being broadcast across all displays". 
     
    Sorry for not following up sooner and I hope this helps!

    terrastorm,
     
    Thanks for the quick reply, even if the news is unfortunate. Well, I have the EVGA unit in hand and the other bits are on the way. I suppose my only hope for now is that my Air is 2014.  Are you running OS 10.9.4?

    Sigh.  Mine only mirrors as well.  I guess this box just isn't ready for prime time when it comes to Apple computers.  I would hope that EVGA would advertise this properly.
     
    I have one only monitor, so with the mirroring, if the newer, larger monitor picks up the signal first the smaller, older monitor cannot display as its unable to handle the freq and dimensions.  Meh.  Had I only known to ask my boss for a Pro instead of an Air. Now I'm stuck.  I just hope EVGA lets me return this box.

    To be honest, I would just keep it for the time being because it will work eventually. The Matrox Dual and Triple head devices will work right now with OSX, however, they don't separate the signals for the monitors. You'll simply have one large resolution that stretches between all displays. They also cost a bit more.

    Sorry to bump an old thread, but has their been any updates on this in El Capitan with having the individual monitors, not just mirroring? Looking to purchase this for my 2014 Macbook pro if so. All 3 monitors are display port.

    As far as I can tell this is supposed to be working now, however, DP 1.2 must be supported on the associated monitors. I updated to El Capitan to test the functionality with the same setup of monitors I used when initially creating this post with my DisplayPort Hub, and it still does not function. I assume that the monitors I'm connecting to aren't DP 1.2 compatible as they're not even DP monitors. I'm using active adapters for DP to DVI. See this link for more information.

    Dear community,
     
    I am owning a EVGA Displayport HUB but unfortunately it does not work. My Acer (DVI(HDMI)) and Viewsonic (DVI) shows the same picture, so its cloned and not using extended or mst mode.
     
    Right now I am asking myself if I purchased the wrong adapters, since I read with MST you should use active adapters.
     
    Would you have any hints for my problem? Someone already got it running?
     
    Config:
     
    Macbook Air 11.1" (Early 2015)
     
    1x ViewSonic VP191s (VGA and DVI)
    1x Acer AL2216W (DVI (to HDMI)
     
     
    EVGA 200-DP-1301-L2 Displayport Hub

     
    SAMTECH Displayport DP to VGA Connector Adapter Male to Female Cable Adapter Converter - Black

    If you are able to out put 2 display signals to 2 different monitors from your laptop then the Displayport Hub is in working order. Your issue with the displays not extended but cloning only is going to be with your display settings within your OS.
