Does my laptop support a second external displays through USB-C or the USB3 ports?

First external display is through the HDMI port of course.

According to the product specs, it does not:

USB 3.2 Gen 1.0 Type-C port; 5 Gbps signaling rate (data transfer only; charging or external monitors not supported)

Thanks for your answer, Paul.

 I need to extend the desktop over three displays (internal plus 2 external), not duplicate the two external displays.

Do you think using an HDMI splitter on the laptop's HDMI port could be a workaround ? I've read the capability of a single HDMI port to support 2 external displays with different content depends on the graphic card, not the port itself.

You're very welcome.

I use a HDMI splitter because I don't have enough HDMI ports on my TV.

However, with the splitter I use (and maybe all of them?) I have to press a button to select the HDMI source.

I recommend you start a new post because I don't know what your options are, if any.
