Windows 10: Dual displays not waking up

I have dual displays set up with HP laptop but don't use the laptop display, when I lock my account then log back in only one screen wakes up. the only way I can fix this is by unplugging the HP dock from the laptop and plugging it back in, then the second screen wakes up.

Dual monitors not waking from sleep

Hi all,

I'm having issues where my monitors won't wake from sleep in a dual monitor setup. This only occurs after waking them from a sleep state, and they work fine when booting up my PC from scratch.

I have tested both monitors in a single monitor setup and the issue goes away completely as they wake from sleep just fine when only using a single monitor. This issue only seems to occur when using both monitors simultaneously.

I have tried the below steps to no avail to remedy the issue:

• Changed the DisplayPort cable
  
• Uninstalled graphics drivers with DDU and reinstalled them again
  
• Made sure Windows update was completely up-to-date, including any optional drivers
  
• Made sure there were no unknown devices in Device Manager
  
• Turned Link State Power Management under PCI Express in Power Plan settings to off
  
• Completely formatted my PC and reinstalled Windows 11
  

None of these steps have resolved the issue.

Any assistance provided will be much appreciated!
