yes it will work – but it will not support VRR also – please note that for this GPU is best to use 4K60Hz as 120Hz might be unstable for this GPU

Hi yes – you can send a mail to [email protected] – the adapter will require a firmware update – its not a driver

[MST1407]

The coating on the connection is indeed silver – please note that the color of this coating does not affect the performance of the cable. This is a VESA certified cable – which means that the Cable performs as it should be.

Hi It does not support VRR – What GPU are yo using? 

 

[MST1407]

Hi Joevt, based on the specifications of Thunderbolt4 it will support 2x4k60Hz or 1x8K30Hz. Club3D tested this setup with Intel NUC with Iris XE and with a similar Lenovo Iris XE Thunderbolt 4 based solution. The actual image should show one or the other and not make it look like one and the other. While typing this – this image will be adjust to correct this. 

There are a few points you mentioned in regards to DSC, while we have not been able to detect a DSC 1.1 solution that can convert HBR 2 to HBR 3 without DSC, theoretically this is correct. We have only been able to detect DSC 1.2 compression on latest Nvidia RTX2X series where Decoding takes place. However as you know for DSC to work, Decode, Encode and Bypass needs to take place. We think that Iris xE should be able to do this as we have tested it with the CAC-1085/CAC-1586 adapters but not able to find DSC working on the Thunderbolt 4 hub. with the integrated chip. 

the CSV-1580 is more a hub than a dock – note that some streams go to the video output support x2 and the rest is going for data. 

Suggestion when you want to have three displays will be best to go for DisplayLink solution. Adding an MST to the Thunderbolt 4Hub does not work. its still limited to two displays. DisplayLink solution that adds the third display from the source that support HBR3 would be the best scenario. This is a work in progress within Club3D

Hi individually thats possible but not when you want to connect dual. The display bandwidth allocated via this dock does not allow for both to run at 2K but a max of 1080p for dual display

you should ask directly to Club3D – send a mail to [email protected]

will check the AGDC Diagnose asap – about the specs, I am wondering on the HDR function of the display – its 350-400nits at its peak. the monitor is 8Bits + FRC , not native 10Bits which has given in the past some troubleshooting issues for the correct HDR ecosystem. Its always best to test on a display that can handle 10bits and above 400 nits. will be best to follow vesa standards on this. could you contact [email protected] to make sure you have latest firmware of the adapter 

[MST1407]

Hi just tested the CAC-1586 which is USB C to the M1 and 3840*2160 at 60Hz with HDR is no issue – how did you test the CAC-1080 / CAC-1085 ? I think the CAC-2504 is also ok with HDR 

 

[MST1407]

The CAC-1080 is backwards compatible yes, but it will be limited in performance by the Source device. So when you are connecting it to a DP1.2 device then it will not support HDR.

[MST1407]

Hi perhaps you can specify which splitter 🙂 

[MST1407]

you might consider the CAC-1080 +

Hi so the HDMI cable that was able to do 4K60Hz on the TI2080 gives you the same problem with RTX3080TI? That seems an issue with the GPU – what is the PSU that you are using? 

 

[MST1407]

When connecting the MST Hub for the first time – could you please try to connect one display at a time so that the system recognizes the displays and resolutions via the MST Hub and then restart the PC? Do you have the same issue?
