Windows from HDMI monitor move to DP monitor when monitors go to sleep.

Hi Bobbeloos,



Welcome to post in Microsoft Community.

I'm Mosken, I do apologize for the inconvenience that you're experiencing right now, let me help you figure it out.



According to your description, I knew that you have two external monitors of similar model connected via HDMI and DP, but when the system goes to sleep, the DP-connected monitor goes straight to black, but the HDMI-connected monitor shows "no signal" and then goes black, and when you go to sleep from sleep, the DP-connected monitor goes straight to black All windows in HDMI monitor moved to DP monitor when computer was woken up and the resolution was not normal. If my understanding is wrong, please correct me in the reply.



Based on the available information, the speculation is that when the system goes to sleep, your HDMI connected monitor will be directly disconnected, it is recommended that you turn off "Allow the computer to turn off this device to save power" by follow steps. "Win" + "X" > "Device Manager" > "Display Adapter", double click "Display Adapter" to expand the entry, you will see a list of your monitor device names, then select your external monitor device names(try both), right click > " Properties" > "Power Management" tab, then uncheck "Allow the computer to turn off this device to save power", then press Enter to confirm.



The above steps are provided based on the information I have learned so far, I wish that will be helpful to you. If your problem still cannot be solved by these steps, you could tell me the specific situation in the next reply. I will continue to assist you in solving the problem.

Monitor will not wake from sleep

When my PC wakes from sleep it always used to wake the monitor as well but now when the PC wakes the monitor does not respond. The only way to solve the problem is to do a hard reset of the PC. The PC is definitely waking from sleep. it is just the monitor.

I have read multiple forums trying to find a solution but nothing seems to work. things I have tried:

• updating BIOS
  
• restoring Windows
  
• running Windows Update
  
• trying a different monitor
  
• checking monitor settings
  
• turning off Fast Startup
  
• Running Troubleshooter Power
  
• turning off Link State Power Management
  
• Restarting in Safe Mode
  
• Updating and Rolling Back the display adaptor
  
• checking that keyboard and mouse can wake the PC
  
• probably a few more that I have forgotten

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!
