The Obvious Suspects: Monitor Settings And Buttons
Sometimes, the solution lies in the simplest of places – the monitor’s settings and buttons.
Monitor Buttons And Controls
Check the power button: Ensure that the power button is functioning correctly. Try pressing the button for a longer duration or shorter duration to see if it makes a difference.
Check the input source: Verify that the monitor is set to the correct input source. If you’re using multiple inputs (e.g., HDMI 1 and HDMI 2), try switching between them to see if the monitor turns on.
Brightness And Sleep Mode
Check the brightness: Ensure that the brightness is turned up. If the brightness is set to zero, the monitor won’t turn on.
Check sleep mode: If your monitor is set to sleep mode, it may not turn on immediately. Try moving the mouse or pressing a key on the keyboard to wake it up.
The Not-So-Obvious Suspects: Graphics Card And Drivers
In some cases, the issue lies with the graphics card or drivers.
Graphics Card
Check the graphics card: Ensure that the graphics card is properly seated in the motherboard and that the power connectors are securely connected.
Check for dust and debris: Dust and debris can accumulate on the graphics card and prevent it from functioning correctly. Try cleaning the graphics card and its connectors with compressed air.

Check for driver updates: Outdated drivers can cause issues with the monitor. Use the Device Manager to check for updates for the graphics card driver.
Roll back drivers: If you’ve recently updated the drivers, try rolling back to a previous version to see if it resolves the issue.
The Computer Itself: Hardware And Software Issues
In some cases, the problem lies with the computer itself, rather than the monitor.
Hardware Issues
Check the motherboard: A faulty motherboard can prevent the monitor from turning on. If you’ve recently installed new hardware, try removing it to see if it resolves the issue.
Check the power supply: A failing power supply can cause issues with the monitor. Try using a different power supply or replacing the existing one if it’s old or faulty.
Software Issues
Check for viruses and malware: Malware can cause issues with the monitor and computer. Run a virus scan to ensure that your system is clean.
Check for firmware updates: Firmware updates can sometimes resolve issues with the monitor. Check the manufacturer’s website for updates and follow their instructions to apply them.
Advanced Troubleshooting: The Last Resorts
If none of the above steps resolve the issue, it’s time to try some advanced troubleshooting methods.
TRY THESE LAST RESORTS
Try a different monitor: If you have access to a different monitor, try swapping it with the non-functional one. If the new monitor works, it’s likely a monitor-specific issue. If the new monitor doesn’t work, it’s likely a computer-specific issue.
Try a different computer: If possible, try connecting the monitor to a different computer to rule out any issues with the computer itself.
Conclusion
In conclusion, a monitor that won’t turn on when the computer is on can be frustrating and puzzling. However, by following the troubleshooting steps outlined in this article, you should be able to identify and resolve the issue. Remember to start with the basics, such as power and connectivity, and work your way up to more advanced troubleshooting methods. With patience and persistence, you should be able to get your monitor up and running in no time.
