Hi Lucy. I'm Greg here to help.
I see a lot of reported issues with USB-C to HDMI adapters, in fact any adapters for monitors in Windows are very likely not to work for many reasons because the native method is always much, much better.
But you can troubleshoot USB-C to HDMI monitor connections not working to see if one of these fixes work - I've collected them all:

Feel free to ask back any questions. If you'll post back detailed results then I may know what to suggest next, if necessary.

How can i get my computer to recognize my HDMI port?
How can I enable the HDMI port on my computer?
I have been using an HDMI cable + HDMI to USB-C adapter to connect two monitors to my laptop. My main monitor is directly plugged in to the HDMI-socket, and the USB-C adapter to the only USB-C socket on the laptop. It's been working flawlessly until yesterday. Now the second monitor just displays "No HDMI signal" and goes to sleep mode. It does not even recognize me plugging in the USB-C cable. Take note that I've done zero (0, nil, no) changes to my setup.
Naturally I thought that the adapter was faulty since I did some testing with the USB-C socket (it charged my iPhone), and the HDMI-cable was working. Purchased a new HDMI to USB-C cable but to no avail.
On my laptop the device manager shows my monitor as a "BillBoard Service".
Has anyone run into this problem? Google is not my friend in this matter, even though I am a man of lurking the internet. Can someone point me in the right direction here?
Many thanks.
Edit: Okay so it got solved by turing the laptop off, then holding the on button for 30 seconds and letting go. What this triggered I have no idea but it might help someone out.
You probably bricked it. Some devices don't have appropriate safeguards in their firmware update procedures, so if you unplug it in the middle of a firmware update, the new firmware may have only been written partway, leaving the overall firmware image corrupted and unusable. Check with the vendor for recovery procedures, but it might be irrecoverably bricked.
Sounds like the driver did not get installed properly.
If the only thing you changed prior to it stopping to work;
- Open Device Manager (Windows+X).
- Find the Firmware tab and open it.
- Open the one you recently updated (double click).
- Driver Tab.
- Roll Back Driver (middle option).
Then reboot and it should work. Then re-do the installation of the firmware.
Windows version: 10.0.19044 Build 19044
Hardware: Lenovo laptop with 1650ti Nvidia & AMD Ryzen 5 4600H (AMD Radeon Graphics)
Recent softwares: I have used "SpaceDesk" a software used to share your pc screen to you apple device. (I have deleted it)
The problem: I'm trying to connect a WORKING(checked) screen with WORKING(checked) hdmi cable to my laptop. But the pc won't even see it being connected. It has worked in the past many times, before i had downloaded the "spacedesk" software.
What have i tried: I have look at almost every single video/posts/forums i could find, tried everything in order, tried to connect with another hdmi cable, tried to use another screen, software updates, command lines for fixing broken windows softwares, checking for driver updates (all graphics are up to date), i suspect the "spacedesk" is my problem, but i don't know why it doesn't still work after deleting it.
Last thing i want to do is recovery, i don't have the energy or the time to find & collect & store all of my personal files just to fix a problem that shouldn't be here. Any help is appreciated, thank you in advence.
EDIT: Nothing worked, i guess the port is broken. Going to send it for repair. I don't know how a hdmi port just stops working while not using it.
