Windows 10: Odd issue with HDMI connection to monitor

I have a HP Spectre x360. This laptop doesn't have a HDMI port. Instead I use a USB-C to HDMI/VGA adapter. No issues until the recent 1903 Feature Update. After this update, my laptop will not recognise the monitor that is connected.


I have troubleshooted in the following ways:


- Connecting a Samsung Galaxy phone to the monitor via the same HDMI and USB-C adapter - Success, the adapter, cable and monitor must be working.


- Connecting my laptop to a different monitor using a VGA connection with the same adapter - Success, the laptop can at least handle a second monitor via VGA.


- Uninstalling and reinstalling laptop graphics drivers - no success. When connecting the monitor via USB-C to HDMI, in Settings>System>Display - the "Rearrange your displays" visual simply doesnt appear.


So it looks like my laptop is struggling with HDMI input - but via a HDMI to USB-C adapter, since there is no HDMI port.


Could not find a way to restore it back to before the update.


Any help appreciated.

Can't connect laptop to monitor via HDMI

Hi Parallax,

Thank you for your response.

We’d like to get more information regarding this issue.

1. Are you trying to connect for the first time?
2. If not, has it worked before?

It seems that the monitor/TV which you are trying to connect does not have setting to change input mode. Kindly refer to suggestion provided by 'Sandeep
Ghatuary' dated July 1st 2011 HDMI - connect desktop computer
to monitor.

Looking forward to your response.

Monitor not receiving signal from pc after using hdmi passthrough

Hi,

Thank you for writing to Microsoft Community Forums.

HDMI Pass-Through does not work with all devices. Before attempting to set up an HDMI Pass-Through connection, you should make sure the source of the signal such as a Blu-ray player or Set Top Box, supports HDMI Pass-Through.

In order to get clarity on this issue and assist you with appropriate troubleshooting steps, please reply with the answers to the questions below.

1. Did you try a different HDMI cable to connect your PC to the monitor?
2. When you say "my pc will not display to my monitor", are you able to see any error message on it? For example: 'No signal'.

Meanwhile, try the below suggestions and check if this helps.

• If your monitor has an option in the Menu Button to switch the
  Input Source to HDMI Port, I would suggest you to try it.
• Try completely disconnecting your Xbox from the computer and just connect your computer to the monitor and check if you are able to see the display on the monitor.
• Make sure your display is plugged in and turned on.
• Unplug the video cable from both your display and PC, and then reconnect them firmly. After you reconnect the video cable, try moving your mouse on your display.
• Try connecting to different video outputs on your PC. Sometimes a change in driver can cause the video to be sent to a different display adapter or output.
• If you have your own display adapter installed and connected to your display,
  try connecting your display to the built-in video on the motherboard.
• Check for damaged HDMI cable, loose connections, or faulty adapters.

Hope it helps.

We're looking forward to your response.
