Hi madbrain,

Sounds like a compatibility issue to me between the Docking Station and the Active adapter. It is not uncommon that Active Adapters like the CAC-1080 do not work well together with other active devices like Docking Sations / Switches (etc.) in the same signal line. 
Indeed, most LG screens need to have UHD Color manullay set to “enable” to support 4K 60Hz. And please make sure to have HDR disbaled.
Did you try making a custom resolution in the Intel Graphics Driver? SOmtimes it helps to overwrite what Intel Driver thinks  is a good setting …

Shoudl be something liek this … 

–          Custom Resolution Intel Graphics Software

Making that Custom resolution in the Intel Graphics Driver should be something like this …

Open Intel Graphics Control Panel, choose “Custom Resolutions” (left bottom option) It will ask you if you wish to continue; YES
Standard the “Basic” setting is shown, click on “Advanced”, make sure you make this custom resolution for the correct screen (left bottom)
Fill in; Width 3840; Height 2160; Refresh Rate 60 ; Set Timing Standard to CVT-RB for use with TV (and for use with Monitor you can leave that on “Auto”). 

If possible please set Color Depth BPC to 8 Bit. and click on “ADD” on the right bottom of the window. Now this resolution I added to the system and can be chosen. 
Go back to “General Settings” (left top), it will show the basic options and here you can now choose the 3840×2160 resolution at 60Hz. 
(You might need to so a reboot first)

Good day madbrain,

Which Lenovo laptop do you have?
If it has a DP output, did you try connecting it direct, without the docking in between?

[MST1407]

I am thinking the screen could be having a compatibility issue, Please check with Dell for a firmware update for the Screens.

To make sure the Docking Station is ok, is it possible to connect another screen then Dell U2212HM to it ?

Hello jun1us,
Ok, the adapter is fine, so it must be software.
Problem is that software is in all the hardware. Please update all also TV.
Then my guess would be that the problem comes from the Intel Graphics Driver.
Great CPU’s but not the most “advanced driver software in the world”.
Is there any particular reason why you needed to update driver 21.20.16.4542 that was working ok ?

Good day HAW,

What screens are you using (Brand / Type)?
What Cables are you using to connect them to the Docking Station?

When connecting the screens and turning them on, does you MacBook see/recognise them ?
If not please do this.

Disconnect Docking Station.
Uninstall all DisplayLink Software.
Reboot.
Download and install latest Software for MAC OS
you can find that here:
http://www.club-3d.com/en/openpdfz/2423_2/zip/displaylink_sw_mac_osx_10.13_12_11_version_4.1.zip/
Reboot.
Now connect CSV-1460 and it should work in proper manner.

Hi jun1us,
Did you try making a custom resolution in the Intel Graphics Driver ?

In general

• Setup

Setups with TV’s normally work best by making a custom resolution, in this case for: 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.

Hell Jun1us,
For Kaby Lake it is better to update the firmware fro the adapter to “0.55” version.
Iw ill have [email protected] send you an email on that.

[MST1407]

Hi Graviton, yes that would mean you would need another adater like CAC-1080 but then with USB C / Thunderbold connector.

[MST1407]

Hi Graviton,
There is indeed a newer firmware version than V7.2b, i will have [email protected] send you that by email.
However, the CAC-1504 adapter does not support HDR if that is waht you are looking for. As far as i know there is no DisplayPort 1.4 Alternate Mode, which is needed for HDR support, in the market yet.

Good day AmlmA,

Sorry to hear this.
Club3D does not have any spare parts anymore for 7870XT Cards unfortunately.
The card is build on a reference HD 7950 PCB so any 3rd party cooler (like Arctic or Gelid or something like that) made for HD7950 should fit on the card.

[MST1407]

glad to hear you got it working 🙂
Thanks for the feedback.

[MST1407]

could also be a driver issue … perhaps try a driver version from before RX400 / 500 series came out. 
Not sure if your card will accept it but 16.8.3 was a really good driver and 17.2.1 was also quite ok.

Hello hadog,

That indeed does not sound good, which is very odd.
To make Eyefinity work, you need WIN Vista or newer and use the DP1.2 ouput on the Graphics Card. MultiStreamTransport (MST) feature is supported by DisplayPort 1.2 spec and WIN, meaning grpahcis cards with DP1.2 ouput are able to output multiple video streams over a single DP1.2 output. An MST Hub is able to recognize and distribute those video stream (with sound even) to connected screens.
Some screens need to be set to DP1.2 for the DP input in the menue of the screen (factory default would be DP 1.1).
MST Hubs are active devices and do not work well together with other active devices like Active adapters / Cables/ Switches / CrossFire / SLI setups.
Thats it, shoul dbe like “nothing more to it” …

I was asking becuase it sounds like the adapter is working ok and your system is working fine, so the chance it is a software issue is quite large. Biggest influence in htis case would be the Intel Graphics Driver Pack whcih also contains UHD sound driver. Please check if you can find latest version for your OS for that one.

[MST1407]

Teh UHD sound driver is integrated in the Graphics Driver. which Graphics Driver do you have installed ?
