Monitor not detected over hdmi

[DB210]

Hi, when I try to connect a monitor via the hdmi port, Windows cannot detect the monitor (by clicking Detect in Multiple display settings).  I have updated Windows, graphic drivers and HP Bios today using the HP Support Assistant, then restarted the laptop, but it didn't fix the problem. I could connect the monitor to another laptop, so the monitor and hdmi cable are fine. Thanks

Hi @DB210,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

If Windows cannot detect your monitor connected via the HDMI port, follow these steps to resolve the issue:
 

Verify HDMI Device Input:
 

• Ensure the HDMI input source on your monitor is set correctly (e.g., HDMI1).

Check the HDMI Cable and Connection:
 

• Confirm you are using the correct HDMI cable and ensure the connection is secure and tight at both ends.

Restart Devices:
 

• Disconnect both the HDMI cable and the monitor, and then reconnect them. Restart your laptop to see if this resolves the issue.

Display Settings:
 

• Press the Fn + F4 keys on your laptop to switch screen output to the external display. This shortcut can vary by model, so check your keyboard for a function key with a monitor icon.

Install the Latest Drivers:
 

• You mentioned updating graphics drivers, but ensure they are correctly installed. Sometimes reinstalling the driver can help.
• Check if there are manufacturer-specific drivers for your laptop's HDMI port. Official HP® Support

Configure Display Choice and Screen Resolution:
 

• Adjust the screen resolution and display settings in the Display settings under Windows. Sometimes, setting it manually can force detection.

Power Saving Mode:
 

• Press any key or move the mouse to exit power-saving mode if the monitor has been idle.

Perform a Hard Reset:
 

• Turn off your laptop, disconnect all non-essential peripherals, remove the power cable, and hold the power button for 15 seconds. Reconnect everything and turn it on.

BIOS and Firmware:
 

• You mentioned the BIOS was updated. Double-check if there are additional settings related to external displays in the BIOS that might need adjustment.
  
  
  I hope this helps.

Take care and have an amazing day!

Hi,

Thanks for your help. Now it works. I downloaded the AMD graphics driver on their website and installed it. It said the installation was successful but gave me a 207 error code, saying that Windows detected a potential issue with my graphics device. I looked for some info about the 207 error, then went in device manager and saw Windows has disabled my AMD graphics driver. So I enabled the AMD graphics driver in Device manager, and after that the problem is solved. I can now see the display on my screen monitor.

Thanks

My HP Envy does not detect an extra monitor after an HP software update on or about Jan 2nd

When I connect a different laptop there is no problem.

How do I find what was updated so I can install the previous version(s)

HI @DB210,

Thank you for your response.

Great to hear—the driver clicked back into place, and your screen shines bright again.
