Based on insights from Windows 10 forum discussions, here are the top tips to resolve random monitor disconnects related to sleep and power settings in Windows 10.
Check Your Monitor and PC Connections
Before diving into Windows settings, first ensure your monitor is securely connected to your PC. Verify the video cable between your monitor and computer is properly plugged in on both ends. If using a laptop, check it is also firmly connected to the power outlet.

Windows should automatically detect your display when powered on. If not, manually initiate detection in Windows Settings > System > Display by selecting ‘Detect’ under ‘Multiple Displays’. Still not working? Press Windows key + P and choose ‘Extend’ to check the external display is active.
Update Outdated Graphics Drivers
Outdated, corrupt or missing drivers are a common source of monitor connectivity issues. Using outdated NVIDIA or AMD graphics drivers can lead to crashes, black screens and connection drops.
Open Windows Device Manager and expand the ‘Display adapters’ section. Right click your graphics card driver > Select ‘Update driver’ to automatically find and install the newest driver from Windows Update.
For the most up-to-date graphics drivers, visit the NVIDIA or AMD website to manually download and install the latest versions. Using their GeForce Experience or Radeon Software utilities also makes updating graphics drivers quick and simple going forward.

Does Windows 10 have hybrid sleep?
Windows 10 offers a feature called hybrid sleep that combines both sleep and hibernation features into one. If this is enabled, it’s worth toggling it off to see if you can enter the normal sleep mode. Search for Edit power plan in the Start menu and select the Edit power plan option. Select Change advanced power settings on the following screen.
Open Windows Power & Sleep Settings and select ‘Additional power settings’ to access your current plan. Change ‘Turn off the display’ to Never and disable hybrid sleep under ‘Sleep’ to prevent display sleep activation.
Try switching power plans to the ‘High performance’ profile. This prevents hard drive, processor and graphics card power state changes that can crash monitors.
You can also tweak advanced power settings for PCI Express, graphics cards and USB suspensions to prevent device power down states that disrupt monitors.
Run Windows Troubleshooters
Windows includes built-in troubleshooting tools that can diagnose and fix common monitor connectivity issues.
Open Settings > Update & Security > Troubleshoot and run the ‘Hardware and Devices’ followed by ‘Power’ troubleshooters. Follow the steps to detect and apply recommended monitor and power settings fixes.
The Windows 10 troubleshooters act like technicians to identify and resolve many monitor disconnection problems automatically.
Eliminate Software Conflicts
Software bugs, corrupted files and background programs can also interfere with monitors. Use the System File Checker tool to scan Windows system files and replace corrupted ones that may be crashing your display.

Updating device firmware, BIOS, chipset and other hardware drivers can squash bugs causing monitor connectivity issues too. Check vendor sites for the newest versions.
