Fix: Monitors Turning Off After Boot on Windows
Given below are five fixes to solve the issue of your Windows PC’s monitor turning off immediately after boot:
- Check for Hardware and Power Supply Issues
- Restore the Default Power Plan
- Disable Fast Startup if Enabled
- Turn off Hybrid Sleep
- Reinstall the Driver of the GPU
Check if the monitor turning off after boot in Windows issue is resolved or not exists after trying each method.
1] Check for Hardware and Power Supply Issues
Your monitor might not turn on after a boot because of a loose or damaged cable connection between your monitor and computer. Check that all connectors are securely attached. If any appear worn or broken, replace them with new cables. If you have another suitable monitor, use it as a replacement to see if it addresses the problem.
If a cable attached to the computer is not correctly removed, the VGA/HDMI port may be damaged or bent. Furthermore, some users may attempt to connect a cable to a connection that does not match, which might damage the gold or silver connections inside the port. In this situation, take your computer to a repair shop to have the bent or damaged ports repaired.
2] Restore the Default Power Plan
Some users who have experienced the monitor turning off after boot have confirmed that the power plan settings cause the display shutdown. This issue can be resolved by restoring it to the default power plan. This is how you do it:
- Open Windows Terminal (Admin).
- To restore the default power plan, use the following command and restart your PC:
3] Disable Fast Startup if Enabled
The Fast Startup feature in Windows is known for creating this issue, especially when the CPU is kept inactive for an extended period. A lot of people have reported that they were able to resolve this problem by going into the Power Options menu and disabling the Fast Startup option.
If you have enabled the fast startup option, follow our guide’s steps to disable it from the Power Options menu. Instead of checking, you need to uncheck the option in the Power Menu.
4] Turn off Hybrid Sleep
Hybrid sleep is another power option linked to the monitor turning off during boot issues. Hybrid sleep is a power condition that mixes sleep and hibernation. When you use this function, your operating system writes all of its RAM to the hard drive or SSD and then enters a low-power state to refresh the RAM.
While this option is excellent in theory, many Windows users say it cuts the display to their secondary displays when their PC is idle for too long. When this problem arises, the only option to restore the display is to restart the computer.
To prevent this from happening in the future, go to the Power Options menu and change the default power settings to disable hybrid sleep. Follow our detailed guide on it.
5] Reinstall the Driver of the GPU
Some graphic driver dependencies could also cause the monitor to turn off after boot. If this is the case, you should be able to resolve the issue by uninstalling the GPU driver (together with any associated dependencies) before reinstalling the most recent version from scratch. Before reinstalling the GPU driver, remove any remaining files from the previous installation.
Follow the steps given below to reinstall the driver of the GPU in safe mode:
- Press the Windows key + R, copy and paste the following command into the Run dialogue box, and press Enter:
- In the Device Manager window, expand Display adapters, right-click each graphic driver available, and click on the Uninstall option from the context menu.
Note: Your screen may flicker once you complete the uninstallation. This occurs because your operating system will turn to the generic drivers.
- After uninstalling all the graphic drivers, go to Windows Settings > Apps, go through the installed application list, and delete anything connected to your GPU manufacturer (NVIDIA, AMD, or Intel).
Note: To avoid missing graphic drivers, click on the Publisher column, which will sort the programs alphabetically. Next, right-click on each GPU-related dependency or driver and choose Uninstall from the context menu.
- Once the uninstallation process begins, follow the on-screen instructions to complete the process.
- Next, follow our detailed guide on how to install GPU drivers in Windows.

Why Is My Monitor Not Turning On When I Turn On My PC?
Possible reasons for a monitor not turning on when the PC is started include loose power connections, faulty cables, an incorrect input source, PC hardware issues, outdated drivers, or a malfunctioning monitor. Check power connections, cables, and input sources, and update drivers. If the problem persists, consult a technician for further diagnosis.
How Do You Check if the RAM Is Damaged?
To check if RAM is damaged, run a memory diagnostic test using built-in tools like Windows Memory Diagnostic or third-party software like Memtest86. These tests will identify and report any memory errors. Additionally, reseating and testing the RAM modules individually in different slots can help isolate potential issues.
