Hello,

I am planning to buy a NUC8I7BEH in the future, my only question would be that, how can I connect three Full HD displays to that?

I have a DELL U2211H, a P2214H and a P2217H.

For the P2214H the manual says:

“*Support DP1.2 (CORE) specification. Excludes High Bit Rate 2 (HBR2), Fast AUX
transaction, Multi-stream transport (MST), 3D stereo transport, HBR Audio (or high data
rate audio)”

For the P2217H it does not say anything about the exclusion of MST, only that it has a DP1.2 port.

I do not ha DP Out on any of these displays, therefore daisy chaining is not possible.

Can I use an MST Hub in this case?

The “Excludes […] Multi-stream transport (MST)” does not really fill my heart with warmth and I am afraid because of the DP1.1a on the U2211H there will only be mirrored image for one of my displays.

What would you recommend?

Thanks!

Hello Bozsikarmand,

Thank you for your question.

currently there are only two solutions available. the CSV-1477 this is an adapter that works via the USB-A connection on your NUC device. you would need two of this product to connect all 3 displays.

the other solution is the CSV-3242HDA which would not utilize your display-ports but will use your VGA, DVI and HDMI all three of these ports are supported on your displays. on Club3D instagram “@Club_3d” account you can see a video how this Dockingstation is used for multiple displays

unfortunately MST is not supported by your Dell U2211H. so a conventional MST will not work

Kind regards

I don’t understand what you mean by “MST is not supported by your Dell U2211H”. An MST hub does not output MST. It outputs SST so it doesn’t matter what the display supports. Even if there is a problem with the DisplayPort input of the display, the display can use DVI input instead. DVI displays work with MST hubs with a DisplayPort to DVI adapter.

So get a real MST Hub.

CSV-1477 and CSV-3242HDA use DisplayLink (video over USB). Avoid them if an MST hub works.

Hello joevt,

Dp 1.1 does not support mst hence the question of this gentleman.

You might want to read into that for more information I would like to direct you to.

Driving Multiple Displays from a Single DisplayPort Output

For all devices it is clear the source needs to give the ability to output that signal. Dp1.1 what this person is using does not have the bandwidth to put out mst.

Hello joevt,

The output on the pc is Dp1.1 this version of dp output does not support mst. So a real mst does not work.

You are able to find additional information about dp in the link below

Driving Multiple Displays from a Single DisplayPort Output

If the source does not put out mst over DP there is no way it will support it. In this case DP 1.1 does not have support for mst output. By the lack of bandwidth.

The MST signal is provided by the NUC8I7BEH which contains Intel integrated graphics supporting DisplayPort 1.2.

The MST Hub knows the capabilities of the display, and will output an appropriate SST signal.

my appologies, yes your options is valid however, the owner of this question does not prefer mst.

but many thanks for your input it is appreaciated

The thread is titled “Recommend an MST HUB”. He asks the question “Can I use an MST Hub?”. I think he wants an MST hub.

His problem with MST (as he described) is that his monitors don’t support chaining. The article you linked talks about chaining but in the last paragraph mentions the hub option.

you are right joevt, do accept an appologie when one is made, my appologies 🙂

you are very well informt a true addition to this forum.

No apology necessary, but accepted. 🙂

Anyway, while an MST hub should work for 3 Full HD displays (even 4 should work, since DisplayPort 1.2 supports 4K which is four 1080p displays), I don’t think Intel graphics supports more than 3 displays, even if some of them are connected by an MST Hub.

The NUC should allow connecting 3 displays without an MST hub. This way, they can all be 4K. One display connects to the HDMI 2.0a port. Two displays can be connected to the Thunderbolt 3 port using a Thunderbolt 3 to Dual DisplayPort adapter or similar device. Strangely, their documentation doesn’t mention this feature of Thunderbolt 3, only implying that only one display is supported from USB-C (which is true for DisplayPort alt mode but Thunderbolt 3 is different). I don’t see any reason why two displays via Thunderbolt 3 wouldn’t be supported, as only supporting one would be a waste of a DisplayPort output from the Intel graphics.

HI I have the same NUC unit as you. To get two DP port from the USB-C port I used this device and work fine. I was initially worried about he word SPLITTER, but with MST get two independent display. I have older DVI Displays and used ACTIVE DP to DVI adapters on each output.

Club3D MST HUB USB Type C to Display Port 1.2 Dual Monitor Splitter CSV-1545, Black

With MST you are splitting the bandwidth. CSV-1545 allows two 4K 30Hz displays. With a CAC-1507 USB-C to DisplayPort adapter and a CSV-5300A triple DisplayPort hub, you can connect 3 Full HD displays.

With Thunderbolt, you get two full bandwidth DisplayPort 1.2 SST signals which allows two 4K 60Hz displays.
