how to find out if my older laptop supports multiple displays using docking station

[melv2012]

I have researched multiple websites and cannot confirm if my HP Laptop can support multiple external monitors using a docking station. Currently my laptop only has 1 HDMI port to plug into 1 external monitor. So I have a docking station also plugged into the laptop which goes to a 2nd external monitor. However, that 2nd external monitor is not detected. How do I get it detected or how do I confirm I cannot use 2 monitors?

Hi @melv2012 

The laptop's USB-C port is not compatible with DisplayPort, which is why you cannot use a second monitor. You can only do so if you purchase a dock with DisplayLink technology, which uses software and hardware to transmit images through the USB ports. Here is a link where you can find out more about these docks.
