Inconsistent Video Signal on SEDK1001A

    I have a strange behaviour with the model SEDK1001A.

    When I connect it to the USB-C Port on my desktop computers GPU, I get the BIOS screen and after that no video signal anymore (on both HDMIs + the DP). When I log in (connected to screen directly), put the computer in sleep mode and wake it up again, the display connected to the dock appears and works as expected. 


    With my laptop, everything works as it should.

    I tried a different usb-c cable, hdmi-cable and updated the drivers. 

    Any recommendations how to troubleshoot that issue? 

    Edit: With or without video signal, the other connected USB peripherals work.

    Hi,

    Thanks for your purchase and for taking the time to contact us.

     

    Can you please tell us if your desktop computer's C port supports video output? Before using the docking station, it's essential to consider the compatibility issue.

     

    Apologies for the product issue, and thank you for giving us the chance to help!

     

    Best regards,

    Judy

    Hi! Thanks a lot for your response!
    Yes, the port supports video output. It is the USB-C port of my GPU (Gigabyte RTX 2080 Super Gaming OC Rev 1.0). 
    When i did the "workaround" as mentioned in my initial post, it works.

    Hi,

    Generally, when the computer is set to sleep mode and wakes up the computer, you need to unplug the docking station and plug it in again. But it looks like you have to put to sleep mode and wake it up, and the docking station works.

    Can you please take a video showing the BIOS screen, put the computer in sleep mode, wake it up again, and send it to Support01@seloretech.com?

    We'll help you through email.

    Thanks for your support and understanding.
