This part works perfectly and monitor indeed going into standby mode. But after about 300 second (being in standby mode) it wakes up by itself. Then after another 1 minute its going into standby mode again and then it won't wakes up by itself again.

Hello

The monitor waking up by itself after going into standby mode on Windows 11. This could be due to various reasons such as outdated drivers, incorrect power settings, or certain devices waking up your system. Here are some steps you can try to resolve this issue:

 

Update Your Drivers: Ensure that all your drivers, especially your graphics driver, are up to date.

 

Check Power Settings: Go to Settings > System > Power & battery > Screen and sleep. Check if the settings for sleep are as you expect.

 

Disable Devices That Can Wake Up Your System: Certain devices like your mouse and keyboard can wake up your system. You can check which devices can wake up your system by opening Command Prompt and typing powercfg -devicequery wake_armed. To disable a device from waking up your system, go to Device Manager, find the device, right-click on it, select Properties, go to the Power Management tab, and uncheck 'Allow this device to wake the computer’.

 

Disable Hybrid Mode: If your PC has hybrid mode enabled, it could cause issues with sleep mode. You can disable it by going to Control Panel > Power Options > Change plan settings > Change advanced power settings > Sleep > Allow hybrid sleep, and setting it to Off.

 

Use Windows 11’s Power Troubleshooter: Press Windows + i and click Troubleshoot. Click Other troubleshooters. Scroll the list to find Power. Click Run beside it once found. Windows will now automatically check for power-related issues and suggest the necessary fix based on your current setup.

 

As for the .etl log file, it contains event trace data that Windows generates. You can view the contents of an .etl file using Event Viewer. To do this, open Event Viewer, go to the Action menu, and choose the option “Open saved log”. Select Trace Log files (*.etl), locate your file, and click Open. This will convert the .etl file into event log format, allowing you to read its contents. However, interpreting .etl files can be complex and might require a deep understanding of Windows internals.
