Not sure if this is a common issue with AMD, but I know it is a recurring issue with the Nvidia drivers as I used to get this all the time with my Nvidia RTX3080Ti for the monitor that was on HDMI.

I kept having to roll back to the Dec 2024 drivers (v563?) and then re-install.... or do a full DDU and then re-install.

Without more information on your system, it's difficult to recommend what to do, but I don't play the latest AAA games and the games that I do play tend to perform better on the older drivers anyway, so I've left mine rolled back to the older drivers and disabled auto-updates as Nvidia's driver updates since Dec 2024 are most vibe-coded garbage anyway.

That said two big things have changed since I last daily-drove Windows on my main PC (6 months ago!):

There is a recently identified, widely-communicated security issue with all older Nvidia drivers that makes the latest drivers a sensible option, ESPECIALLY if you're playing games with kernel-level anti-cheats.

This solution is quite specific to my own setup, but this might work for you: I got so fed up with losing one of my side screens (the HDMI one), that I swapped out both side screens (HDMI + DP) to my motherboard video-out ports, so those are now driven by the CPU (AMD Ryzen 7800X3D) - it is terrible for running games on those screens, but I only game on the main screen (RTX3080Ti) and the output for those side screen actually runs a LOT better; smoother YouTube video and no webpage corruption when I run low on Video memory (VRAM) on the main GPU.

Hi,

What is the monitor model?

What is your GPU?

Have you tried a different HDMI or DP cable?

Have you tried the monitor on another PC or video device?

Thanks

Try these steps in order, focusing on what commonly breaks after a Windows update:

Confirm Windows is using Extend/Duplicate

Press Windows logo key + P.
Select Extend (or Duplicate) instead of PC screen only.
Check if the second monitor appears.

Basic hardware checks already done

Physical connections and power cycling are already checked; also try a different video cable and, if available, a different video output port (HDMI/DisplayPort/VGA/DVI) on the PC to rule out a bad port.

Check how many monitors the adapter supports

If using a splitter, it will only duplicate a single signal and cannot create a second independent display. Use a proper docking station or USB-C video adapter if a second output is needed.

Reset the graphics driver

Press Windows logo key + Ctrl + Shift + B to reset the graphics driver.
If the screen flickers and then returns, check Settings > System > Display to see if the second monitor is detected.

Roll back the display driver (since the issue started after an update)
In the taskbar search box, type device manager and open Device Manager.
Expand Display adapters.
Right-click the display adapter > Properties > Driver tab.
Select Roll Back Driver if available and follow the prompts.
Restart the PC and test the second monitor again.
Reinstall the display driver If Roll Back is not available or does not help:
Open Device Manager and expand Display adapters.
Right-click the display adapter > Uninstall device.
Check Attempt to remove the driver for this device and select Uninstall.
Restart the PC.
After restart, open Device Manager again, right-click the display adapter > Update driver.
Choose Search automatically for updated driver software and complete the installation.
Run Windows Update again

Go to Settings > Windows Update and select Check for updates.
Install all available updates, then restart and test the second monitor.

If still not working

Use Feedback Hub to file a bug, including that the second monitor stopped working immediately after the update and what troubleshooting steps have been tried.
