Windows 10: HDMI monitor loses connection in Windows 10

I have a dual monitor setup on a Radeon RX 580 8GB graphics card. Randomly, after I unplugged my secondary monitor through HDMI then plugged it in again it stopped working. I have tried everything from checking hardware to updating my bios and everything in between (installed newest driver from manufacturer site, windows button p, settings menu, unplugging computer for a set time, fresh install on windows 10 without updates). If I boot the computer with only the second HDMI monitor connected the bios will pick it up but when Windows takes over it loses it's connection. My primary is connected through Display Port. If anyone has suggestions please let me know.

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 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.

 

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.
