Solved!

Connecting two external displays to laptop with single HDMI port

HP Recommended
HP Pavilion Laptop 15-cs3721nd
Microsoft Windows 10 (64-bit)

How can I connect 2 external monitors to the HP Pavilion Laptop 15-cs3721nd?

 

Eventhough this datasheet (https://www8.hp.com/h20195/v2/GetPDF.aspx/c06472706.pdf  (In Dutch)) says it has USB-C  Thunderbolt, it does not. It's just USB-C for data transfer, as it says in the specs.

 

The specs for the external ports say:

1 USB 3.1 Gen 1 Type-C™ (Data Transfer Only, 5 Gb/s signaling rate); 2 USB 3.1 Gen 1 Type-A (Data Transfer Only); 1 AC smart pin; 1 HDMI 1.4b; 1 headphone/microphone combo; 1 RJ-45

 

All the USB port support 'Data Transfer Only'.

 

So (how) can I connect a second display (extent the desktop not duplicate)? The first display is connected to the HDMI port.

 

I've seen a "sollution" on the forum (https://support.hp.com/in-en/document/c04641829) but that only explains how to add screens but I know how to do that, I first need a way for the laptop to recognize the second display.

Thanks in advance for your suggestions.

@Mike_112, Welcome to the HP Support Community!

 

You will have to use a HDMI splitter. USB type-c is used for data transfer. 

For more info on USB type-c, refer to this document - Using USB Type-C to Transfer Power and Data

 

Hope this helps! Keep me posted.

Thank you Kumar for your response.

Wouldn't a HDMI splitter do exectly that, split the signal ergo duplicate the desktop?

I'm looking to extend the desktop....could a HDMI to USB 3.1 adapter be a sollution ?
