How to connect HP Pro Mini 400 G9 to monitor with only USB-C ports?

[williamchan]

I have a HP Pro Mini 400 G9 Desktop PC (Serial # :[Personal Information Removed]), which has an HDMI port and USB-C ports *without* Thunderbolt. My monitor only has USB-C ports. (My monitor is an LG, https://www.lg.com/us/support/products/documents/22MD4KA-B%20Spec%20Sheet.pdf.)

What is the best way to connect my HP computer to my LG monitor? I have tried using a HDMI-to-USB-C cable, which did not work. My HP computer does connect successfully by HDMI-to-HDMI to a different monitor that I borrowed for testing.

I am looking at HP USB-C Dock G5 (https://www.hp.com/us-en/shop/pdp/hp-usb-c-dock-g5-p-26d32aa-abl-1) and I am wondering if that will work. I am also wondering whether an HDMI converter or some other option would work.

The specs of your machine is

Do you have  (1) Flexible Port 1 (rear) ? If yes you should be able to use this port to connect to a USB-C monitor. The HP USB-C G5 dock won't help.

Regards.

I do not have a flexible rear port. These are my rear ports. I think this means I have to get a monitor with an HDMI port and connect with an HDMI-to-HDMI cable. Thanks for letting me know that a HP USB-C G5 dock won't help.
