There are several possible causes of a display going blank in Windows. The cause of the issue will depend on the type of hardware and software associated with the display. In some cases, a driver issue or inadequate power supply could be to blame. In other cases, a hardware issue or compatibility issue between the display and the computer could be causing the issue. Below is a list of potential causes of a display going blank in Windows.
1. Inadequate power supply: The power supply that is supplied with the display may not be strong enough to properly power the display. If the power supply is insufficient, the display may go blank. It is also possible for the power supply to become damaged or overloaded, leading to the display blanking out.
2. Driver issues: Outdated or incompatible display drivers can cause the display to go blank. If the correct drivers are not installed or are outdated, the display may not work properly. To resolve the issue, check to make sure you have the latest drivers or reinstall the display’s drivers.
3. Hardware problems: A faulty video card or display cable can cause the display to go blank. If the display has recently been moved or connected, check to make sure the cable is properly connected and that the video card is securely seated.
4. Software problems: If the operating system has recently been updated, the display may be unable to recognize the updated software. This can lead to the display going blank. To fix this, download and install any available updates.
5. Heat issues: If the computer has been running for an extended period of time or has recently gone through a stressful operation, it can cause the display to go blank due to excessive heat. Allow the computer to cool down and then try turning it back on.
6. Compatibility issues: If the display is not compatible with the computer’s hardware, the display may go blank. Check to make sure the display is compatible with the computer before connecting it.
7. Bad settings: If the display settings are incorrect, the display may go blank. Check the display settings in the control panel.
8. Bad monitor: If the display is old or has been damaged, it may be unable to properly display an image. If the monitor is old, replace it with a new one. If it has been damaged, consider returning it for repairs or replacement.
