Using the HP Spectre x360 Convertible 15-ch0xx with 4 monitors.

[madcowtricks]

I have a Spectre x360 Convertible 15-ch0xx and a Plugable USB-C Triple 4K Display docking Station with DisplayLing USB Graphics, Alt Mode Video Output and PD Charging.  There is one HDMI 1.4 connector, and two DisplayPort++ outputs in the back.  It works great using the Thunderbolt 3/USB-C output connecting to the laptop.  So I still have the HDMI port on the laptop that is not being used.  However when I use the HDMI port on the laptop, it doesn't seem to recognize it. Only the docking station connections work.  How do I get the three docking station monitors a the build in hdmi port to display at the same time? 

How many displays will this laptop drive.

I'll be glad to assist you with this to provide you with an accurate solution, I'll need a few more details:

To identify if it is a port or the cable issue, please try the below.

Could you please check if the HDMI cable works fine with the other monitor? 

Try with a different HDMI cable and check if it works.

Keep me posted.

Thank you for joining the HP Community.

Have a great day!

Cheers 🙂

I am very embarrassed that I didn't try that first.  But for anyone looking around, the configuration I used above, with good hdmi 2.0 cables, does in fact push 4 external monitors (5 if you count the laptop screen).

@madcowtricks That's alright, no need for embarrassment, sometimes brilliant minds overlook the obvious, it happens to me too 😛 😉 jokes apart, I appreciate you letting the community know that 4 external displays work with the laptop, thank you & have a good day.
