Experiencing Windows update was a security update (KB5079473) (26200.8037) issues where your HP monitor is randomly going black and then coming back on.
Here are some detailed troubleshooting steps you can follow:
1.Check Cable Connections
Ensure all cables are securely connected: Occasionally, cables can become loose or disconnected, particularly HDMI, VGA, or DVI cables.
Try different cables: Sometimes cables might be faulty, so it's advisable to try using different cables to see if the problem persists.
2.Update Graphics Drivers
Check for updates: Visit HP's website for graphics driver updates.
Use Device Manager: Open Device Manager, find your graphics adapter, right-click and select "Update driver software."
Manual installation: If updates are available, download them manually from the Hp website and install them.
3.Revert Windows Update
System Restore: If the recent update may be causing the issue, consider reverting your computer to a previous restore point when the monitor was functioning properly.
Uninstall update: Go to 'Settings' > 'Update & Security' > 'View update history' > 'Uninstall updates,' and uninstall the recent Windows update to see if this resolves the issue.
4.Check Power Settings
Adjust power plan settings: Navigate to 'Control Panel' > 'Power Options' and ensure your monitor is not set to turn off or sleep too frequently.
Disable sleep mode: Try setting your power plan to 'High performance' and make sure that display sleep settings are set appropriately.
5.Monitor Hardware Check
Test the monitor: Connect the monitor to another computer or device to determine if the issue persists. If the monitor works correctly, the issue may be with your PC.
Inspect the monitor’s hardware: If the problem continues, check for any physical damages or issues with the monitor itself.
6.Scan for Malware or Virus
Occasionally, malware may interfere with device functionality.
Use Windows Security: Perform a full scan to rule out any malicious software.
7.Additional Diagnostics
HP Support Assistant: Use the HP Support Assistant for diagnostics and ensure all drivers and firmware are up to date.
Possible Causes
Driver Conflicts: Recent software updates sometimes lead to incompatibility issues with existing drivers.
Power Settings: Incorrect power settings may cause monitors to turn off intermittently.
Hardware Issues: Faulty cables or damage to the monitor may also cause random blackouts.
Software Bugs: Sometimes an update can affect system performance and hardware interaction leading to malfunction.
