It did not work on your Dell 2715Q because the monitor does not support 4K 60Hz on its HDMI input, that only support 4K up to 30Hz.

Hi mblataric,

Please try first without the Denon receiever in between.
FW version is mentioned on the label of the Adapter should be someting like “V7.55”.

In general

• Setup

Setups with TV’s normally work best by making a custom resolution, 3840*2160 at 60 Hz with Timing Standard set to CVT-RB (Reduced Blanking).

(For setups with Monitors Timing Standard can remain on “auto”.)

On most TV’s you will need to do some settings like “Enhanced Mode”/ “PC-Mode” and/or “UHD Color” for the HDMI 2.0 port in use. 

Please make sure the HDMI port of the Screen/TV supports 4K 60 Hz, often not all HDMI inputs support that.

 Pleas make sure to use a Premium HDMI 2.0 cable capable of doing 4K 60Hz / 18Gbps

 

• Custom Resolution

To be able to generate such a Custom Resolution you will need an app like SwitchResX since MAC OS does not provide such settings.

Should be something like this, please do make sure to have it set to “CVT-RB”

You might need to make a new user, certainly if you already had it installed before.

Hi anon,
Sure you can always ask.
Just don’t have a date for you yet 🙁 
We know DisplayLink is really doing all they can to get Apple to cooperate, because all products from all brands with DisplayLink Chips stopped working after MAC OS update. Normally Apple will fix similar issues cause by OS Updates in about 1 month. But again this is just an edjucated guess.

Hi FunkyMst,
I will aks for that to be tested too
Will get back to you soon.

[MST1407]

thanks for the feedback

Hi anon,
Yes of course, this is a high priority and very important to us to get such functionality back working again for our customers. We are doing all we can together with Displaylink to fix this. Unfortunately the only thing that changed was the MAC OS update, so we most probably will need cooperation from Apple on this one. “Unfortunately” because that might take more time to solve the issue.

This sounds like the either the source system does not support MST or the Graphics does not support DIsplayPort 1.2.
The MST Hub should be recognized by the system (or the screen connected to the hub). Then in WIndows Display Settings you can check if the resolution/frequency is correct and choose mirro/extended mode.
Outputs of the MST HUb are DP++ so when converting DP ouput of the MST Hub to HDMI or DVI please use passive adapters, like CAC-1000 / CAC-1001

Hi Anon, thats it CSV-1474.
Just got word of that issue, unfortunately Apple updte 10.13.4 was quite intrusive…
DisplayLink (maker of the Video Chip and Driver software) also recently posted these topics …

https://support.displaylink.com/knowledgebase/articles/1849327

Iw ould advise to roll back to 13.13.3

Good day FunkyMst,

CSV-5200 and CSV-6200 have the same chip inside so are very similar.
The build is a bit different though,
CSV-5200 the USB cable for power integrated (cannot be disconneted) where hte CSV-6200 has a separate USB Cable.
CSV-5200 has a reaset button on the back which will cause the video signal to be build up form scratch again, CSV-6200 does not have this.
Thats it.
Let me dubble check that Adaptive Sync Support, because I kind of doubt that. I mean these MST HUbs were already here before adaptive sync was …
Will let you know shortly.

Good day Srikanth,

What graphics chip is used on the source system?
For MST to function the source need to support it, meaning it needs to support DisplayPort  1.2 and the OS should also support MST, like WIN 7 / 8.31 / 10. MAC OS for instance does not support MST.
With regards to power, i am quite sure all DP connections should offer power, but with regards to the MST Hub that gets enough power from the Power Adapter.

[MST1407]

I saw Displaylink posted some items on this as well …

Indeed it seems that Apple did it again :-S
I would advise you to roll back to 10.13.3.

Hello Toby8787,

That is a new one for me, but indeed does not sound good.
PC is working OK Still ? (i mean wihtout the adapter).

[MST1407]

Hello Anon,

Which product do you have? 
Itmecode shoudl be something iike “CAC-1504 or CSV-2300H” ….
What system you have?

[MST1407]

For the HDR feature to work, you would need a Graphics Card with DisplayPort 1.4 Output, WIN 10 Fall Creators Edition RS3 (build or newer) and Nvidia driver 390 (or newer).

I will ask [email protected] to send you by email the latest firmware for the adapter that became available yesterday.

ah ok, i get your point now, was not aware of that.
Well if your notebook is nto abel to output 4K at 60Hz over its TB2 output, the CAC-1170 or CAC-2170 or any aother adapter like it, will not help you.
They just convert from DP to HDMI, they do not increase frequency or resolution.
They only work around for that would be to use an External USB Graphics Adapter like
CSV-1474
http://www.club-3d.com/en/detail/2412/sensevision_usb_a_to_hdmit_2.0_dual_monitor_4k_60hz/
or CSV-1477
http://www.club-3d.com/en/detail/2413/sensevision_usb_a_to_displayportt_1.2_dual_monitor_4k_60hz/

Those will use a free USB 3.0 port and will aloow you to feed 2 x Screen at 4K 60Hz resolution for sure!
