Windows 10: Monitor "no signal" when waking up from sleep.

I've played around the power settings, made sure my bios is updated and also checked that my graphics drivers are updated. I have also done a full reset of my PC using the Windows recovery tool. After the full reset the monitor was turning on again after waking up from sleep, but then a few hours later it was back to the same problem. I did a second full reset and again the monitor was working properly for a few hours and then the problem came back. I'm not sure why the full reset is not fixing it pemanently. Any help would be much appreciated.

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!

 

Primary monitor gets no signal from PC after waking up from sleep mode.

I recently set up a second monitor for my PC. Everything works fine except for the monitor which shows no signal after my device has been in sleep mode. The monitor works and turns on like it should, but it loads up the installed Samsung software saying there is no signal to the PC. My secondary monitor immediately wakes up, and the primary only recognizes the PC if I restart the system or am powering it up after it has been shut down. This only occurs after the device has been in sleep mode. How do I get my main monitor to have a signal as well?

The monitor that receives a signal from the PC is a 2560x1440p 165hz Samsung Odyssey G5 (Secondary)

The monitor that does not get a signal when I wake the system unless I restart is a 2560x1440p 240hz curved Samsung Odyssey G6 (Primary)

The monitor works and turns on like it should, but it loads up the installed Samsung software saying there is no signal to the PC.
