Windows 10: USB C to HDMI not working

I want to connect an external monitor to a laptop with no HDMI port, but it is not getting a signal via HDMI through a USB c hub. I can get VGA connection with the adapter/hub, but the HDMI connection does not work. I have tried two different adapters and two different HDMi cables, but neither work with HDMI.

USB-c to hdmi adapter doesn’t work

It should if you have USB-C, but even then these adapters are not that reliable - nowhere near as good as using an HDMI or Display Port cable.

Did you try the troubleshooting steps I gave you? This will let you know if it can be made to work and remain stable.

This is an interactive process. I give steps to perform, you do each one and then report back results until something works, so I know what to suggest next. If you need help performing any step, just ask back. But please do not skip any steps. We often find out the skipped step is the fix.

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:

USB C to HDMI/VGA adapter no longer working

1. What are the hardware specifications of the current USB-C to HDMI/VGA adapter? If it is convenient, please try to share the hardware information, including the speed of the cable and the specifications that the adapter itself can support. COMSOL CMHV02
   
2. Given that you have already tried to replace multiple USB-Cs, this may not be a problem with Firmware and Intel(R) UHD Graphics drivers. You can try to unplug these USB-C to HDMI/VGA adapters on other computers and observe whether the video output signal is good. I don't have another computer to try it on but this was working, as I used it for work then I took time off and it's now no longer working. so I purchased new ones because I thought it was due to an old one and none are working. so it's the slot, not the adapters.
   
3. At the same time, please check the usage of your USB-C output port. If you use a USB-C that does not have a video output, it may cause problems. Please refer to the ASUS official description of the USBC of the device: [Notebook] How to determine the function of USB Type-C ? | Official Support | ASUS Global This originally worked so this can't be the case.
   
4. In the meantime, try connecting an external monitor via the HDMI port on the device itself and see if the output is good. the monitor is fine - no issues with the monitor.
   

As this was previously working I believe it was due to some type of update. how do I go about rectifying this? I called ASUS and they told me they cant help me. lol
