  Hello,

  I purchased the Selore 13-in-1 USB-C Docking Station (SKU: DK1407) on December 8, 2024. The device was working fine untill today. I started experiencing a serious issue with the video outputs.

  • Both HDMI ports and the DisplayPort are completely non-functional.

  • I tested with multiple HDMI and DP cables (all confirmed working).

  • Other devices tested on the same cables and monitors work fine.

  • All other ports on the dock (USB, USB-C, SD card reader, etc.) function normally.

  • The issue is isolated only to the video outputs.

  This makes the main advertised feature of the docking station (multi-monitor support) unusable.

  Could you please advise on:

  1. Troubleshooting steps I may have missed.

  2. Whether this unit is defective and needs replacement.

  Thank you in advance for your assistance.

  Additional details for context:

  • I’m using a Windows laptop with this docking station.

  • The Display Settings in Windows do not recognize any external monitor when connected through the dock’s HDMI or DP ports. However, the external monitor is recognized immediately when connected directly to the laptop, so the issue is specific to the dock.

  • The docking station does successfully charge the laptop when plugged in, so power delivery is working.

  • I ordered the device from Amazon. The order number is #112-3718108-0099466.

  • To reconfirm: all other dock functions (USB, USB-C, SD reader, etc.) are working fine—the issue is only with video output.

  Please let me know if further information (e.g., system specs, driver versions) would help in diagnosing the issue.

  Hi @Gaston Perez,

  To better solve the problem, please provide the following information:  

  1. Please provide the specific model of your laptop.  
  2. Has there been any change in your usage environment, such as switching computers, monitors, or upgrading the system?  
  3. Please try connecting the device to another computer that supports video output and check if it functions properly.  
  4. Please provide detailed connection diagrams or a video (including the computer, monitor, and the product).

  Best regards
