Firmware on both the monitor and the computer’s motherboard can impact sleep and wake functionality. Manufacturers may release updates that fix bugs or improve compatibility with operating systems.

  • Visit the monitor manufacturer’s support page to check for firmware updates.
  • Update your computer’s BIOS or UEFI firmware through the manufacturer’s official tools.
  • Review third-party software that manages power or display settings, as these can sometimes interfere with standard wake operations.

Disabling or uninstalling conflicting software temporarily can assist in diagnosing whether these programs contribute to wake failures.

Advanced Settings: BIOS and Device Manager Adjustments

In some cases, changes within BIOS or Device Manager are necessary to resolve monitor wake issues. Important settings include:

  • Wake-on-LAN: Enables network activity to wake the computer.
  • USB Wake Support: Allows USB devices to wake the system.
  • PCI Device Power Management: Prevents devices from entering deep sleep states.

Accessing Device Manager in Windows allows you to modify properties of input devices:

  • Right-click the device and select Properties.
  • Navigate to the Power Management tab.
  • Ensure “Allow this device to wake the computer” is checked.

Incorrect configurations here can prevent the monitor from waking even when input is detected.

Steps to Reset Monitor and Graphics Settings

Sometimes, resetting your monitor to factory settings can clear issues caused by corrupted configurations. This process varies by model but typically involves:

  • Using the monitor’s on-screen menu.
  • Selecting “Reset” or “Factory Defaults.”
  • Confirming the reset.

Similarly, resetting graphics settings through the GPU control panel (such as NVIDIA Control Panel or AMD Radeon Settings) can restore default display parameters that may be affecting sleep behavior.
