Some otherPotential Causes of USB C to HDMI Not Working and How to Solve Them

The following are the possible problems noticed when connecting USB C to HDMI as complained by several users across the web and their corresponding fixes.

1. Not Detected, Nothing Displays

So assuming after connecting your USB C to HDMI and you discover the device is not detected, any of these two possibilities must have occurred:

i. There is no supply of video output signal from the host device. This may mean that your USB C port output is not able to give native DisplayPort Signal.
ii. There may be connection error even though the USB C port can supply video out signal.

Case i.

Ensure that your host device has the function of providing DisplayPort ALT Mode
Make sure that the host device protocol you are sending the signal from has the ability for DisplayPort ALT Mode. If it does not have, you may not be able to send Audio /Video output through the port irrespective of the USB C to HDMI adapter quality used.

Case ii.
If you are able to verify that all the 4 ports of the USB C are functioning optimally by being able to supply DP Alt Mode, then check to be sure the HDMI to HDMI cable works fine and if so, then you will have to replace the USB-C to HDMI Adapter.

2. USB C to HDMI Not Working Due to Dedicated Adapter Driver Issues.

Another reason why your USB C to HDMI may not be working is the problem with the Adapter driver.

Update the adapter driver to enable the connection function smoothly without any issues.

  1. To update the driver just go to press a combination of the Windows Key and the letter S and type in Device Manager.
  2. Under the Device Manager, expand Other Devices.
  3. Then right-click USB device and click on Update Driver
    As soon as the driver gets updated, if the driver update was the issue, USB C to HDMI connection will start working immediately.

3. Connection May be Detected But There May be Black Screen

Most of the time if this happens, then we have high probability that the adapter/cable must have been used for long stretch of time between 4 to 12 months duration.
Another reason is there are high chances that you just upgraded the system.
This issue is common with Windows operating system users for example when you upgrade from Windows 10 to Windows 11.


In this case also, it could be adapter driver issue. So you follow the steps earlier indicated above to update your driver accordingly.
Keep in mind that if this step doesn’t address the issue, sometimes it may be due to hardware problems as well.

4. Not 4K60Hz, 144Hz, as then case maybe.

If there is the above complain, it’s most likely the output capacity issue is involved.


Follow the steps below as guides:
 Ensure you have a device with the capacity to output 4k60Hz
 Make sure your adapter/cable will be able to get 4k60Hz
 You must ensure the input external display supports 4k60Hz
 Keep in mind the whole connection requirements are met adequately to avoid most of those issues.

Connection checking Tips:
These quick clues can be handy to assist in checking your proper connectivity.

  • Remember to investigate if the output device supports the standard required.
  • Check if the cable/connector supports this standard.
  • Make sure the input devices also support this standard.

5. Flickering Screen

This problem could be related to the following possible causes:
i. There may be an error on the connection between USB C and the Display.
ii. It could also be that the adapter went off.
iii. Another possibility is that the HDMI to HDMI cable is poor quality or faulty as a whole.
iv. Again, another possibility is that the HDMI cable length is more than 25ft.
v. The display itself may also be faulty.


1. Check to be sure the connection between the USB C and the display has no issues by checking the connecting medium such as the cable.
2. Make sure the adapter is powered On.
3. Ensure the quality of the HDMI to HDMI cable is high and good for the connectivity efficiency.
4. The maximum length of HDMI cable should not be more than 25ft long as it may start dropping off signal if more.
5. Troubleshoot the display itself to be sure it is not faulty.

And one way to confirm that is to test with another compatible display


Thus USB-C to HDMI not functioning is not a big issue. This issue can be solved easily by following the proper steps.

Still, if the problem exists then you need to contact the PC experts to find out about the problem causing this issue.

Also, never attempt solutions told everywhere. Always go for the solutions available on authentic and genuine websites. Further, you do not need to worry a lot as this is a small issue and it can be solved instantly.
