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.

 

HDMI port suddenly no longer sending signal to 2nd monitor?

Oh wait, forgot to list what I have tried already.

- Changed HDMI cords to see if the cord was broken (not the issue)

- Uninstalled and disabled graphics driver (not the issue)

- Ran the Troubleshooter for Devices and Hardware (not the issue)

- Reboot (not the issue)

- Virus Scan (not the issue)

- Check for updates (not the issue)

- Check hitting Windows Key plus P (currently set to Extend and working fine with VGA cord - not the issue)

Note: When in the Display Settings and pressing on the Detect button, nothing happens. Looks like page tries refreshing to find the 2nd monitor but nothing happens.

I'll need some more advanced hardware advice for this one.

When plugging into the HDMI port, the HP monitor lights up signaling that the power is detected but quickly flashes no signal and goes dark. Seems like the port does work but doesn't want to send the video signal.

Is there a default setting somewhere that forces the HDMI port to send a signal no matter what?

Come on fellow Windows Users! I need some real know how on this one!

 

Monitor not working - HDMI has no signal

Yesterday, my ASUS monitor was working fine connected to my HP spectrum using Windows 10. Today, the monitor delivers a no HDMI signal message. I have restarted both laptop and monitor, replaced the HDMI cable, updated display driver and still no luck.
Suggestions welcome.
