Cannot connect an external monitor by USB-C

[franz_krystian]

My HP laptop is Envy 13-ah1125nd, which has a USB-C port. Although i have checked the manual and stated that it supports Display port output, i don't see the display port icon next to the USB-C port. Unfortunately, my external monitor cannot receive any signal when the laptop was connected with a USB-C - to - Display port adapter, and a Display port to HDMI cable connected to the monitor.

My question is, if this laptop is capable to connect an external monitor (standard 1920 x 1080)? Furthermore, do i need any drivers for display output? This laptop is equipped with nVIDIA GeForce MX150, but i could not install any drivers (which is downloaded from HP) and thus i only use the internal Intel display.

The specs of your machine is

It USB-C port supports Power Delivery, DisplayPort™ 1.2 it also has 65 W AC power adapter therefore you can use USB-C Gen 5 port to connect to more than 2 monitors (depending on resolution). The USB-C to Display port with DisplayLink certified should work.

I have this laptop. The screen got broken off, but it still worked. so, I got a new pc screen and hooked it up. It worked. Randomly, the laptop screen stopped working. Then  somehow, on the computer, the screen got disconnected in settings. Because the laptop screen doesn't work, I can't reconnect it in settings. So now I can't use my computer.😔

I completely understand your frustration. I had the same. 

I bought a connector and it supposes to work as I had checked the manual before i bought it . Just as @Banhien had mentioned it should be compatible. And when I digged into the computer, I found that the laptop was not set as using GeForce graphics but only Intel graphics (this laptop is not used by me but I just gave my hand to solve the problem). What a stupid settings from the factory that a laptop with external graphics was set to use internal graphics as the factory default. And I'm sure the user did not change much about the settings/drivers etc. And when I wanted to update the drivers, most of them which i could download are not working, since the Windows has been updated for a few versions already, and this laptop is only roughly two years old.
