Waking a sleeping PC up causes monitors to continually disconnect and reconnect, making the PC unusable until restarted.

Title: Troubleshooting Monitors Disconnecting When Waking Up a Windows PC

Introduction:
Many users experience frustrating issues when waking their Windows PC from sleep mode, particularly related to monitor connectivity. A common problem involves connected monitors disconnecting and reconnecting repeatedly, rendering the system unusable until a restart. This guide explores possible causes and solutions to help resolve this issue effectively.

Understanding the Issue:
The problem typically manifests when a computer transitions from sleep mode to active mode. After waking, users notice their monitors briefly disconnect, then reconnect, creating a flickering effect that hampers productivity. This issue can be especially troublesome for setups with multiple displays, leading to a cycle of disconnections that require a complete system reboot to resolve.

Potential Causes:
Several factors may contribute to monitor disconnection issues after waking a PC:

Graphics Driver Problems:
Recent updates to graphics drivers can introduce compatibility issues or bugs.
Corrupted or incomplete driver installations may also cause instability.
Power Settings and Sleep Configuration:
Certain power management settings might conflict with hardware components, leading to display issues after sleep.
Hardware Compatibility and Failures:
Faulty or failing hardware components such as power supply units (PSUs), graphics cards, or cables.
Compatibility issues between hardware and driver software.
Operating System Bugs:
Occasionally, OS updates or settings may cause conflicts affecting display output.

Troubleshooting Steps:
To resolve this problem, consider the following steps:

Update Graphics Drivers:
Visit the GPU manufacturer’s website (e.g., NVIDIA for RTX 3060) to ensure you have the latest driver version.
Use the official installer to perform a clean installation, removing any remnants of previous drivers.
Adjust Power Management Settings:
Navigate to Power Options in the Control Panel.
Disable “Allow the computer to turn off this device to save power” for Display adapters in Device Manager.
Set the power plan to Balanced or High Performance and disable sleep timers temporarily to test.
Check and Reset Display Settings:
Ensure the display resolution and refresh rate are correctly configured.
Reset to default settings if necessary.
Test Hardware Components:
Check the integrity of cables and connections.
If possible, test with a different power supply or graphics card to rule out hardware failure.
Inspect for Operating System Updates:
Ensure your Windows OS is fully updated to benefit from the latest fixes and
