Does my Intel 520 on my Surface Book support 3 monitors via a Startech MSTMDP123DP Hub?


Hello Intel Community,

Would appreciate it if you could answer the following question :

I have a Surface Book from Microsoft (not the Performance Base model, but the previous one) . Information from my system in the notes below . The question is : can I use 3 monitors (1-built in, 2 - external, 3- external ) , provided i am using a Startech MSTMDP123DP 3-Port multi monitor min displayport to Display Port MST Hub ?

At the moment I have all three connected, but my system doesnt pick-up the 3rd monitor.

1st Monitor is the Surface Book built-in display.

2nd Monitor is my external Display (connected via HDMI cable)

3rd Monitor is my 2nd external Display ( connected via HDMI cable to DVI adapter, because the Monitor only has DVI port , hence cannot use HDMI with it ) .


For more details i am including the output of my dxdiag.

Hello JRadk, By using Multi-Stream Transport (MST) capabilities, you should be able to distribute one DisplayPort* signal across multiple monitors (DisplayPort* or HDMI* monitors). However, video resolutions will be limited. Since Intel® HD Graphics supports DisplayPort* 1.2, you can configure three displays (built-in monitor + 2 external monitors). If you have any further questions, please let us know. Wanner G. Intel Customer Support Technician Under Contract to Intel Corporation

Thank you for the confirmation. This takes care of one little piggy. If the card indeed supports this, then i will proceed with additional troubleshooting via:

1) resolution

2) dongles ( as suggested by n.scott.pearson below ) and BIOS

Let me make sure I understand correctly: You are connecting this MST Hub to the laptop. You then have a DP-to-HDMI adapter between the MST Hub and the first monitor and a DP-to-HDMI adapter plus a HDMI-to-DVI adapter between the MST Hub and the second monitor.


In theory, this should have worked. I do, however, see a couple of possibilities for why it is failing:


  • The presence of the paired dongles on the second monitor is causing the monitor to not be detected. Check for this using another HDMI monitor (surely you have a TV that could be temporarily repurposed for this test).


  • The BIOS is not simply prepared to handle the MST Hub being there and is thus nor checking for a second monitor. If this is the case, you are simply out of luck.


Hope this helps,






Thanks for the advice. I will try to add the TV temporarily to see if it will be detected and update the thread.


Again, thanks for the advice, but unfortunately i am not progressing.

Here is what i did :

Instead of the 2nd external monitor ( which was connected via HDMI and then DVI adapter to the monitor's DVI port ) I connected my TV. My TV has HDMI , so I no longer needed the DVI adapter.

In essence the setup became:

1)Laptop built-in display

2)MST Hub connected to laptop mini displayport

3) 1st external monitor ,connected via MST Hub HDMI to Monitor's HDMI

4) 2nd external monitor - TV, connected via MST Hub HDMI to TV's HDMI


Pressing the MST Hub's rescan button doesnt detect the TV in 4) and Windows doesnt see additional screens.

The laptop's display and the 1st external monitor work just fine.


I then tried plugging in the cables in the MST hub in a different order , but that also doesnt work. The TV ( under 4) is still not detected.

I then set things up the following way and my surface book still didnt recognize the TV:


1)Laptop built-in display

2)MST Hub connected to laptop mini displayport

3) 2nd external monitor - TV, connected via MST Hub HDMI to TV's HDMI


So the question remains : Does the surface book graphics card i have (listed above) support the laptop built in display and 2 additional external monitors ?

Thanks Intel


P.S. I also tried disabling my Nvidia Card dGPU from the BIOS to see if this will bring any changes. No.

Hello JRadk, Were you able to test the steps provided on this thread? Wanner G. Intel Customer Support Technician Under Contract to Intel Corporation
Hello JRadk, Thank you for your response. Your processor graphics supports three displays (built-in monitor + 2 external monitors). However, Original Equipment Manufacturers (OEMs) usually modify how many displays you can connect at the same time. This also depends on the video connections your system supports. In this scenario, we recommend following these recommendations: 1. Use another adapter. 2. Change the supported resolutions and refresh rates for your device. 3. Make sure the monitors are using the latest firmware or driver versions. 4. If available, check the list of supported monitor configuration and monitors supported by your system. 5. If your product uses a Surface Dock, your OEM may also have a list of validated peripherals. 6. Make sure you are running the latest updates for Windows* and OEM drivers. Wanner G.

And if you have problems, call Microsoft. The Surface Book is *their* design with *their* BIOS. There are all sorts of things that they could do that would block the monitor configuration.
