Can you help to get my external monitor to display?
I have an Alogic USB-C Travel Dock Essential (sold to me with the HP Spectre Laptop). The dock is plugged into one of the USB-C ports and I wish to connect my external monitor via an HDMI cable. This was working previously and the only thing I remember that may be relevant was a pop-up window relating to NVIDIA display. The external monitor will only work via the HDMI port on the laptop but I need to plug in another display via the dock HDMI port. The sounds are heard when plugging in and out so it is recognised but just nothing on the external screen. I thought of trying to change the setting so it uses the Intel Graphics display adapter instead of the NVIDIA but cannot find a setting to configure this. I have two display adaptors:
1. Intel (R) UHD Graphics 630
2. NVIDIA GeForce GTX 1650 with Max-Q Design
Under Monitors in the Device Manager there are two:
1. Generic PnP Monitor (my laptop screen)
2. SD590_S27D590P (my Samsung external monitor)
When I look at Devices in the Control Panel my external monitor (which is currently plugged into the HDMI port) is named with (NVIDIA High Definition Audio) underneath.
So, to recap... I want to plug my external monitor into the HDMI port of the docking station that connects to my laptop via the USB-C port but when I do this there is no display on the external monitor, despite it being recognised.

Welcome to the HP Support Community.
Is the docking station a type-c or thunderbolt dock?
Let us know 🙂
Thanks!

Let's perform a test here:
- Make sure the power cord and adapter is connected to the system and wall outlet.
- Press and hold the power button until the computer turns off completely.
- Turn on the computer.
- Immediately press the F2 key repeatedly, about once every second, until the UEFI Hardware Diagnostics screen is displayed.
- In the UEFI Main menu, select Component Tests.
- In the Component Tests menu, select USB Port.
Click Run once, or Loop until error.
While the test is running, the time remaining and test result for each component display on the screen.
If a component fails a test, write down the failure ID (24-digit code) for when you respond back to us.
Let us know 🙂
