and yes that should work just fine on the USB 3.0 port of a Lenovo S540.

Hi FlorianHCF,
I will have that checked/fixed by the webmaster.
Meanwhile I will have [email protected] send you an email with active link to the driver.

Sorry for the inconvenience.

Hi jefftv,
That is most certainly possible, but if anyone should know it would be LG … i have no access to such info unfortunately. If you are lukcy it is mentioned in the manual, but often you would have to contact the Manufacturer.

Hi jefftv,

You already have the latest available firmware, so from the adapters standpoint it should all be good and working.
Sorry for the inconvenience,

Hi jefftv,
It sounds like the system does not recognise the screen and chooses to send out a signal the screen does not “like” at boot up. After you change settings all is fine, until next boot.
Normally an app like SwitchResX would solve that becuase it overwrites the normal system setting and “forces” the sytem to output whatever you want. That his does not function after boot, it a new one for me.
What firmware is on the adapter (should be mentioned on the label on the cable).?

[MST1407]

HDR mode is not supported.

Only think I can think of is the Pixel Clock,
Please check in the SwitchResX setting what frequency the Pixel Clock is at.

Please note that it depends on the screen if the what pixel clock is supported,  however often automatically is set between 533 and 539MHz.

You have “UHD Color” en-abled in the menu of the TV ?
(or something like “PC-Mode” or “Game-Mode”)

Good day Patt52,

Please check if the Adpater / Cables you are using to connect the Screens are Passive.

An MST HUb has Displayport ++ (Dual Mode) Support. This means when converting the DP output into DVI you need to use Passive adapters. Like our CAC-1000 Adapter (plus of course a normal DVI cable to conenct to the monitor).

Hi jefftv

What build year is the Mac MIni ?
Which OS version do you have installed?

[MST1407]

then i am sorry, but your Notebook is not able to output a 4K 60Hz Signal, since it does not have an HDMI2.0 or DP 1.2 output.
The only solution i can think of is using a product like CSV-1477. 
That porduct you cannot to a USB3.0 output, the driver/software picks up te video signal compresses and packs it, send sit like data over USB3.0 and the GPU inside the CSV-1477 converts tha into max 2 x 4K 60Hz signal.
The CSV-1477 is USB 3.0 to 2 x DP 1.2
The CSV-1474 is USB 3.0 to 2 x HDMI 2.0

Hi Paulius,
ad 6) Are you saying you are using the HDMI output on the Notebook to go to the DP input on the monitor ?
If yes than we found the problem. The CAC-1070 / CAC-1073 is are DP-to-HDMI converters and not bi-directional, so you cannot use them to convert HDMI signals coming from your notebook, inot a DP signal.
Is there a USB Type C output on the Notebook that has Displayport Alternate Mode support?

[MST1407]

Hello Paulius,
Your notebook is capable of outputiing 3840×2160 at 60Hz over the Mini DP 1.2 output.
The adapte is abel to convert taht into HDMI 2.0 signal. Your Monitor has 2 HDMI inputs out of which 1 is HDMI 2.0 or 4K 60Hz capable.   This should work !

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.

Please make sure the HDMI Cable is capable of 4K 60 Hz or 18Gbps.

Please make sure the Software of the Screen/ TV is updated

Just to stisfy my own curiosity, why dont you just use a CAC-1163 Mini-DP to DP cable to connect your screen ?

[MST1407]

Ok, good to hear the cable is doing a good job 🙂

[MST1407]

Hi rms,

A CAC-1066 cable is indeed capcble of doing DP1.4 spec but is fully downwards compatible.
Furthermore a passive Cable like the CAC-1066 does not do anything with the signal other then allowing it to go form source system to screen. 
Perhaps the card is sending out a DP 1.4 signal which the cable can do, but the Screen does not recognise ? Please check setting in the menu of the screen, normally you can set the DP input to “1.2” and then the Screen should send this data at start up to system so it knows what it can send out.

Hi nabostoli,

This CSV-1560 Docking Station uses Multi SteamTransport (MST) feature to distribute a second video signal if it is coming form teh source systems USB C output. Don’t think your MacBook / OS supports that …
