HP ef2030ca - No display when connecting a 3rd monitor

[adri338]

Greetings,

I am trying to setup my brand new HP laptop (model : ef2030ca) to work with two external monitors. I plugged the first monitor in the HDMI output of the laptop and it runs fine.

For the second monitor, I want to use a Dell DA200 USB-C adapter (which provides an additional HDMI port, as well as RJ-45, USB 3 and VGA ports). However, the second monitor, plugged in the HDMI port of the DA200 adapter, displays nothing. I know the adapter works because the HDMI port works with another PC. Also, when using the DA200 on my new PC, the adapter's RJ-45 and USB 3 both work fine.

Is there a setting that I missed, that would allow me to use a second external monitor on my laptop ? If I can't get it to work, it might be a deal-breaker. I would hate to have to return it, I love the laptop otherwise...

Regards,

Adrien
