When running Windows 8.1 with the actual Nvidia drivers, daisychaining multiple displays through one Thunderbolt port is possible. I installed Windows 8.1 on my MacBook via Bootcamp. I tried to find open source drivers for my graphic card and my MacBook which would enable this function, or maybe some hacked drivers, but had no luck yet.Īfter Googling again for some hours, I decided to test the statement (link above) that a MacBook running Windows is able to daisychain.

So I think that Apple is intentionally restricting the usage of Display Port 1.2 with non-Apple screens by limiting this function within the drivers.ĭoes anybody have a solution for this problem, or know what to do? However, I learned that Apple provides the drivers, not Nvidia (“ Nvidia drivers are provided by Apple and they are updated with every OS X maintenance update.”). I tried to download the newest drivers for my graphic card form Nvidia. So, as Windows machines and a MacBook running Windows support this setup, I concluded that it has something to do with OS X running. While Googling I found some articles which say that 'a Mac running Windows will daisy chain monitors'.īoth screens support DisplayPort 1.2 as well as MST (' DisplayPort 1.2 added support for Multi-Stream Transport (MST), enabling multiple monitors to be used via a single DisplayPort connector.') and I enabled Display Port 1.2 on both screens within the menu.

If I connect the same setup to a Windows machine, it is working fine. However, whenever I connect the cables like this, I only receive the same image on both screens, i.e. So the setup I'm trying to run looks like the following: MacBook -(from mDP to DP)-> Screen 1 -(from DP to mDP)-> Screen 2 But I need to use one Thunderbolt/DisplayPort for my Ethernet adapter, so I only have one left.) (I know that I could easily plug each screen into its own Thunderbolt/DisplayPort. I want to use one of my two Thunderbolt/DisplayPort ports from my MacBook to connect both screens via a daisy chain. I just bought a new MacBook Pro Retina 2015 2.5GHz i7, 16GB RAM, NVIDIA GeForce 750M running OS X Yosemite 10.10.3. I think that daisy chaining DisplayPort screens under OS X 10.10.4 is not possible, due to software limitations defined by Apple.Īfter Googling for some hours, spending 1.5 hours talking to the Apple Support and another hour talking to the Dell support, I don't know where else to find a solution than here. Marking this question as an already existing question is wrong as the other question refers to a Mid 2012 NONretina Macbook running 10.10.1 instead of 10.10.3/4
