Does the HP Laptop 15s-du1xxx support DP alt mode

HP Recommended
System Model HP Laptop 15s-du1xxx
Microsoft Windows 10 (64-bit)

We are trying to run dual screen off a System Model HP Laptop 15s-du1xxx using a usb-c to HDMI splitter. The splitter requires DP alt mode. I am guessing this may be an issue (the splitter works fine with other laptops in the house so not an issue). The splitter is a ALOGIC splitter (if that helps).

 

After trying multiple different approaches, have not been able to get it to work.

 

For this laptop for which there is a single HMDI and usb-c, is there an alternative (false safe) way of running dual screens? (e.g., one of the HP docks).

Thank you for posting on HP Support Community.

 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

  1. Select a connection type based on your second monitor.High Definition TV: DVI  or HDMI  cable

  2. Connect the TV or monitor to the computer using the cable you chose.

  3. Connect a power cable to the TV or monitor, and then turn it on.

  4. TV connections only: Change the TV video input source to match the video source connection from the computer (Line-1, Video-1, HDMI, etc.). Refer to documents that came with the TV for instructions.

    Depending on the TV, the image quality might not be as good as that of a monitor.

  5. Turn on the computer.

And, also you need to check the USB-C port compatibility most of the USB-C ports does not support video output. 

You can check the USB port details in product specification page: https://support.hp.com/in-en/document/c01961011

 

Hope this helps! Keep me posted for further assistance.
