Daisy chain Dell u2713h

I have two Dell u2713h monitors on my desk at work.
I also have a Macbook Pro10,1 (early 2013) with a grand total of two TB ports
I need to use one of the two TB ports for a TB-to-ethernet adapter because there are well in excess of 30 wireless access points visible to my computer from my desk which means using our company's wifi is a no-go, I'm literally getting disconnected 1-2 times per minute.
So, I can only use one of my TB ports for my two monitors. Both monitors are DP 1.2 compatible and have 1.2 support activated.
I'm running OS X 10.9.4
As far as I know it should be possible to daisy chain the monitors (I am, of course, running my MBP in clamshell mode with external mouse and keyboard) but when I connect them as follows:
MBP mini-DP out -> Monitor #1 DP in -> Monitor #1 DP out -> Monitor #2 mini-DP in
I just get mirroring.
So, what am I doing wrong? This should work, right?

I cannot get my out of the box one new Dell monitor, model u2415 to work with my MacBook Pro (MBP). I have a MacBook Pro (15-inch, Early 2011). I have no other external monitor.
After working with Dell Tech Support, they tell me it is "Plug-n-Play" and incompatible with Apple. However, I find on YouTube and here, people using this new Dell monitor.
I told Dell, I cannot get any Menu or what have you, to come up on the Dell. Only the "Inputs" selection. I think that's where the problem is.
Frankly, after two nights and four hours or so (also with Apple). I'm about to give up.
Am I missing something? Ideas???

  • Daisy-chaining Dell MST and non-MST display

    Hi,
    I wanted to connect two screens to my MBP:
    1 DELL U2713H (daisy chainable)
    1 DELL U2713HM
    so I connected the U2713H to my MBP via miniDP and daisychained the U2713HM via DP on the U2713H. I activated DP 1.2 on the U2713H. The whole system started flickering on Win 7 and then crashed Windows so bad that I had to reboot a couple of times before everything worked with only the U2713H connected.
    I also tried it on MacOS and here both screens showed a halfway ok picture, but the same one, i.e. MacOS did not recognize the U2713HM only the U2713H
    If I understand the specs correctly, everything should work properly. Any idea why it does not work?

    Hi, thanks for the answer.
    Does that apply to MacOS only or also to Win 7?

  • DisplayPort 1.2 MST (Daisy Chaining) on 2013 MacBook Pros

    Hi,
    If I am not wrong, 2013 MacBook Pros support DisplayPort 1.2, and according to Wikipedia one of the features added in 1.2 is daisy chaining (emphasis mine):
    DisplayPort version 1.2 was approved on December 22, 2009. The most significant improvement of the new version is the doubling of the effective bandwidth to 17.28 Gbit/s in High Bit Rate 2 (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth. Other improvements include multiple independent video streams (daisy-chain connection with multiple monitors) called Multi-Stream Transport, facilities for stereoscopic 3D, increased AUX channel bandwidth (from 1 Mbit/s to 720 Mbit/s), more color spaces including xvYCC, scRGB and Adobe RGB 1998, and Global Time Code (GTC) for sub 1 µs audio/video synchronisation. Also Apple Inc.'s Mini DisplayPort connector, which is much smaller and designed for laptop computers and other small devices, is compatible with the new standard.
    However, on OS X Mavericks, daisy chaining is only supported for Thunderbolt displays and not displays that support DisplayPort 1.2, such as Dell U2713H.
    Is this a limitation of the hardware, or is this a feature that's not supported by Mavericks's DisplayPort drivers and could potentially be supported by Yosemite?
    Thanks.

    Daisy chain Dell u2713h
    Covered in another thread. Short version, Apple hasn't enabled support for it. If you run Windows it works great!. No support in Yosemite either.

  • Black Screen (~10sec) on login/logoff on daisy chained monitors

    Hey guys
    In my setup, I have 2 daisy chained Dell U2414H monitors on the DisplayPort output of my nVidia GTX 760 . They work mostly fine, but I'm getting a roughly 10 seconds delay (black screen) at login and logout. This seems to be an issue with the Intel iGPU, as described on the wiki here. However, the strange thing is, that the black screen only occurs when using both monitors in the daisy chain config (regardless of DP1.2 setting on second monitor). Using one monitor on either HDMI or DisplayPort and even using both, one on HDMI and one on DP, works perfectly fine.
    Any ideas? I might just end up buying an HDMI cable and be done with it, but I'd like to have as few cables going to my monitors as possible
    Thanks!
    This is my /etc/modprobe.d/blacklist.conf

    The computer itself is really old so I have an onboard intel graphics chipset, I also read on the forum about a person who had problems with nvidia but when he installed the nvidia package everything was solved.
    I don't think there is something like this for intel?
    EDIT: Ow nice! I installed the package: xf86-video-intel    2.10.0-1 for X.org Intel i810/i830/i915/945G/G965+ video drivers and everything works like a charm, so it was a driver problem after all, never expected it.

  • Daisy chain two display port monitors (Dell U2913WM) to new Mac mini Thunderbolt?

    Everything I read said that I could hook up a display port monitor to a Thunderbolt port on the mac mini.  I purchased two display port monitors (Dell U2913WM) that can be daisy chained, and hooked them up.  All I get is mirroring.  Does anyone know how to turn off mirroring with this setup?  I did not get the "uncheck mirroring" option in preferences until I hooked up the second via the HDMI port instead of a daisy chain.  The problem with that is, I cannot take advantage of the full resolution through the HDMI.  It seems I have wasted my money on two monitors.
    Looking for advice on:
    1) How to daisy chain these two Dell monitors to the mac mini and turn off mirroring and use an extended desktop, or
    2) How to take advantage of the full resolution through HDMI port?
    Any help would be greatly appreciated.
    Thanks!

    So re-reading this thread, I now realize you did exactly what I wanted to do but your issue was having a cloned vs. extended desktop. Oops!
    I believe your "nothing plugged in" issue is the cable. I'm not sure that TB cables are backwards compatible with DP - I think it's only the ports. Do you see multiple monitors in "System Preferences > Displays" if you hook the monitors up like you described in your OP?
    My Dell U2713H arrived today and it works like a charm with the supplied Mini-DP to DP cable. The built-in display on my 13" mid 2009 MBP still works if not in clamshell mode, although I will mostly use mine in my HengeDock. In the OSD of the monitor, you can access "Display Settings > Display Info" and it will show you the DP capability. Mine is only DP 1.1a and I believe to run 2 of these at full resolution you will need the bandwidth in DP 1.2 which includes MST (daisy-chaining). This could be your problem.
    Can you access the same menu in your OSD and report back what your DP compatability is?
    Thanks!

  • Daisy chain Display Port (U2713H)

    Hi Forum,
    I have a rmbp 15 and 2 Dell U2713H screens that I usually connect to my macbook using both TB/DP ports.
    Now I need to connect another TB device and looked into using the Daisy Chain option on the screens. Although I get image, it seems to be cloned and MacOS doesn't seem to know that the second screen is there.
    My question is, how can I enable Daisy Chain on MacOS?
    According to the specifications this should Work.

    In theory this should work. Can anyone help me with this?
    Thanks in advance,
    Tiago

    I am the OP.
    Please see what I found on another thread that answered my question.
    I just finished researching this for myself, as I was considering adding to my MacBook Pro (2012) a pair of new Dell U2713H 27" monitors that support DisplayPort-based daisy-chaining.
    It looks like Thunderbolt-enabled Macs only support DisplayPort 1.1a which will not allow the kind of MST that you are looking for nor will it enable me to use multiple monitors as I desired. New Thunderbolt chips supporting DisplayPort 1.2 with MST are supposed to be available this year, and so would possibly make it into late-2013 or 2014 Macs.
    It seems the only present ways to connect more than one external monitor to a MacBook are:
    a) using a USB video adapter
      b) purchasing two Apple Thunderbolt Displays
    If someone releases a Thunderbolt docking station with multiple monitor outputs there might be hope, otherwise I think this won't ever be possible with current model MacBooks.

  • Thunderbolt Daisy Chain to a DisplayPort Monitor (Dell 2713HM)?

    I have a Mac mini (2011) that supports my Dell monitor (2713HM 27'') at its maximum reslution of 2560x1440 only through a Thunderbolt to Mini-Displayport cable. As this Mac has only Thunderbolt as a fast connection for backup drives I have to add a Thunderbolt chain with the backup device in the middle and the Dell monitor at the end of the chain if I want bakcups faster than Firewire 800 or USB 2.0 (the other possible connections with this Mac). My first attempt with such a setup was the LaCie eSATA Hub. But this does not feed the display signals through, the monitor stays black. Checked in the store with a genuin Thunderbolt monitor from Apple the daisy chain worked.
    Can my chain work at all? Is only the Lacie the wrong drive hub? Would it work with a Seagate Desktop Hub, for instance STAE122 or STAE 127?
    Can I trick the Mac under Bootcamp as OS to use HDMI for the monitor? Dell officially says that the monitor can only accept 1900x1080 over HDMI, but some have fiddled wth different computers with custom settings that worked with some Monitors but mostly under Linux and to Dell 2711.

    FWIW, STAE129 is the current version TB adapter
    that is self powered and has TB daisy chain port.
    STAE122 and STAE127 are older versions and
    not the current model, though there may be stock of
    these around.  As to whether this will solve your issue,
    I don't know.

    The MacMini HDMI port is hardware limited to 1980x1200.

  • Daisy Chain DP 1.2 Monitor

    I am looking to purchase a Dell Ultrasharp U2913WM 29" Ultra-Wide Monitor and I noticed that it has Display Port 1.2 capabilities through a displayport out and therefore has the ability to daisy chain multiple displays over displayport.
    I was wondering if the Thunderbolt connector would allow me to take advantage of the Dell Ultrasharp U2913WM dasiy chain capablities considering it is compatable with Display Port.

    Thanks, I have already ordered the Caldigit Thunderbolt station, but this DOES NOT solve the dp1.2 issue at all.  In summary, I can hook up both my Dell U2713H monitors today and will also be able to do it via the Caldigit Thunderbolt station, HOWEVER but both require using two ports, MDP for maximum resolution versus HDMI.   I would like to use dp 1.2, which is supported by Intel on TB2, to eliminate using both my TB ports.    However, for some reason TB2 on Apple products are preventing utilization of dp 1.2,     

  • Can The MacBook Pro Retina (2013) daisy chain display?

    I have a 2013 MacBook Pro Retina 15" and a Dell U2713H, I would like to use the video-out via Display Port on my monitor to run another monitor. I know that Display port 1.2 supports daisy chain, as does my monitor, but I do not know what versions the MacBook Pro is using or fi this would work. I'm aware of all of my current options of connecting displays via HDMI & TB I'm getting by with those options now, but would really like to save a TB for a hub and or Drive.

  • Daisy chain monitor from cinema display MacBook Air 5,2

    I know the Mid-2012 MacBook Air is capable of 2 external displays as described here.
    The monitor works when plugged directly into the MBA, but not when daisy chained from the back of the cinema display.
    It's a dell monitor, and I'm using an Apple Thunderbolt-VGA adaptor.
    Is there something I'm missing? Thanks!

    As far as my question itself -- why does this happen? Has anybody had this issue on Lion and had it resolved on Mountain Lion?

  • Can I daisy chain two Thunderbolt displays to the new MacBook Airs (July 2011)?

    I have last year's MacBook Air -- probably the best Mac I've ever had and I've had a few. I looked at using multiple displays last year, but the reviews for the major 3rd-party solutions really demonstrate how little is possible.
    I see Apple says you can double up on displays for the MacBook Pro (I have a pre-Thunderbolt one unfortunately), what about the new (July 2011) MacBook Airs?
    Anyone tried? Anyone know?
    (I have a 30" Dell display, but it is, and always has been, very flakey when it comes to connecting to a Mac laptop).

    You can thank Intel for that.
    The sandy bridge chips all have integrated graphics, and before they were released -- they took nvidia to court claiming they didn't have a "license" to make GPU chipsets for the sandy bridge line.  Intel won, and consumers lost.
    The solution most manufacturers are using for notebooks is graphics switching (nvidia optimus like technology) -- which basically uses a discreet GPU along side the intel integrated GPU, and switches between the two instantaenously based on the workload and \ or battery life -- this is how the macbook pro's with the ATI gpus work.
    Since there isn't enough space physically inside a macbook air for a discreet GPU, and since no company in the world is allowed to make a shared GPU for intel's sandy bridge chipsets -- the only solution is to use the integrated graphics that is in the processors -- Intel HD 3000.  Intel basically has the monopoly here...there is no legal solution in the world another company can provide thanks to our wonderful court system
    Wanna know the really sad part about the Intel HD 3000 GPU?  The Nvidia 320M (the GPU used in the previous model 2010 macbook air -- chip was released to the market in April of last year) actually out performs it in some benchmarks -- that's right, a 1+ year old shared gpu from nvidia outperforms Intel's 2011 integrated graphics.
    Intel ***** at graphics, period.
    The only other solution I can think of is for you to get the "Echo Express" product from Sonnet:
    http://www.sonnettech.com/product/thunderbolt/index.html
    It's basically an external bay that will allow you to put a PCIe GPU inside it, and it would then connect via thunderbolt to the macbook air.
    You would then use the minidisplayport connectors on the PCIe GPU to connect to the apple displays -- I believe any modern ATI or Nvidia GPU can support up to 3 or 4 external displays.
    Unfortunately, sonnet's bay is not released yet, and you'd also have to make sure the PCIe GPU you get supports both thunderbolt AND os x....so yeah, kind of slim pickens right now
    EDIT:
    So apparently the macbook pros can daisy chain two thunderbolt displays -- Apple has a picture of it on their site:
    http://storeimages.apple.com/1867/as-images.apple.com/is/image/AppleInc/MC914_AV 7?wid=1200&hei=1200&fmt=jpeg&qlt=95&op_sharpen=0&resMode=bicub&op_usm=0.5,0.5,0, 0&iccEmbed=0&layer=comp
    I just bought a new mac air too...I was gonna get a mbpro but they are just too expensive -- the one I configured was at around 3000$
    Wanna know what's lame about using the thunderbolt display with the mac air?  So the new mac air has the magsafe connector on one side and the thunderbolt connector on the other -- they're not on the same side like the macbook pro is (see picture) -- so basically the cable is going to have to slack around the back of the macbook air -- who designed that?  Must have been smoking some good meth ;p

  • Daisy chain 2 monitors Mac Mini

    Hello,
    Im currently running a Mac Mini (Late 2014). I'm currently using 2, Dell S2240M monitors, but am in the market for new displays. Currently I have each monitor connected to their own individual thunderbolt port using a thunderbolt to VGA adaptor (as the monitors themselves only support VGA & DVI-D connections). In my research I've come across others dasiychaining monitors together through a single Thunderbolt port, connecting the first monitor to the second via another Thunderbolt cable. Does anyone know the requirements to do this? Am I able to do just as well using DVI-D /VGA to receive the same outcome? Does anyone have another workaround for doing this?
    Ultimately I would rather not pay a thousand dollars twice for two Thunderbolt displays so as you can imagine, Im open to trying other workarounds if anyone has one.

    That daisy-chaining only works with Thunderbolt monitors and App is the only one making them.
    The Thunderbolt port on a Mac, except with a Thunderbolt monitor, uses the Mac's Thunderbolt port as a mini displayport and that does not support daisy-chaining

  • Daisy Chain a second Monitor to Thunderbolt Monitor

    I purchased a new Dell S2040L HDMI Monitor and I would like to Daisy Chain to my Thunderbolt. I plugged the Dell Monitor into the back of the Thunderbolt monitor and my Mac Book Pro (OX Version 10.9.4) will not reconize the Dell monitor as a second monitor. Is there a display setting that needs to be changed?

  • Daisy Chain 24" Monitor to 27" Thunderbolt Display

    Hi everybody,
    I have the 2011 MBP with the 6750m and I want to buy the new 27" Thunderbolt Display. Currently, I'm using a Samsung 24" DVI Display with the Display Port to DVI adapter that I bought with the MBP.
    I was wondering if I can continue to use the 24" and daisy chain it to the Thunderbolt Display?
    Best,
    Luka

    Kevin can you confirm this? Do you have a Thunderbolt Display, with a MiniDisplayport to DVI hooked up to your Dell laptop? I presume this works, but that you only have the monitor and speakers working, without the USB/Ethernet/TB port that are on the back of the display?
    I am waiting for somebody to test this so I can decide to buy the display yes or no so please let me know asap : )
