Have you been facing the ‘Computer turns on, but no signal to monitor’ issue? Don’t worry. I’m well aware of how frustrating and annoying this issue can be. Therefore, learning about the possible reason behind this issue and the fixes you can try at home to eliminate it is essential.
Hardware issues often stem from poor cable connections, like improperly connected HDMI cables between the PC tower and monitor. Faulty monitors or GPU issues can also lead to display problems. Software-related causes include outdated display drivers, disruptive BIOS settings, resolution misconfigurations, and minor glitches.
- The monitor may not be getting a signal due to either hardware or software issues.
- The problem can be fixed by testing the monitor, updating drivers, testing display adaptors, changing the screen resolution, or resetting the BIOS settings.
- If the problem is bigger than what you anticipated, use a professional’s help.

- Restarting your PC.
- Trying another HDMI Cable.
- Make sure to reconnect all the cables to their respective slots.
Testing Another Displaying Device
If you have any doubts regarding your monitor being the culprit. You can test any other displaying devices. Don’t worry; you don’t have to go out of your way to buy a whole new monitor for that. You can use your TV as a display device by simply plugging in the other end of the HDMI instead of the monitor.
Change The Screen Resolution
You may have accidentally set a resolution way higher than what your monitor supports, which might cause it not to turn on. Different users used this method on Microsoft Answers Forum as well. These are the steps to lower the resolution configuration on Windows 11:
- Go to Display: Open the ‘Settings’ app > Click on the ‘System’ tab > Click on the ‘Display’ tab.

Update Drivers
Updating drivers is essential to keep your PC running smoothly. Therefore, you should know how to update drivers. In this case, you must learn how to update the display adaptor or GPU drivers as users discussed this on the forum windows 10. You must follow these steps to update display adaptor drivers through the device manager:
- Device Adapters: Open the ‘Device Manager’ > Click on ‘Device Adapters.’
- Update Driver: Right-click on the display adaptor that you are using > Click on ‘Update Driver.’

Your PC will automatically search for any driver updates, if any.
Try Another GPU
Many processors come along with integrated GPUs. Therefore, if you are worried that the other GPU installed separately on your PC is not working, you can try switching to the integrated GPU on the CPU. On the Windows 10 Forum, users were discussing this very solution and how this can get around the issue and solve it. You can follow the given steps to switch to the integrated GPU:
- Display Adapters: Open the ‘Device Manager’ on your PC > Look for the ‘Display Adapters’ and click on it.
- Right-click and Enable: Right-click on the GPU with your CPU’s name on it > Click on ‘Enable device’ in the drop-down list.

If the integrated GPU seems to be working perfectly fine, the problem may be with the GPU you used initially.
Reset BIOS Settings
Any settings of BIOS that are keeping your monitor from displaying can be reset back to default. You can try the CMOS battery picking-out method to reset your BIOS settings. Resetting BIOS being a possible solution for many users on ASRock Forum was the go-ahead signal for me as well. Here are the steps to reset BIOS using a CMOS battery:
- Shut Down: Shut down your PC > Make sure the power outlet is switched off too.
- Open PC: Open your PC case after a while (make sure no current is flowing).
- CMOS battery: Look for a CMOS battery attached to your motherboard > It is usually close to the PCI/PCIe slots. However, the location of the CMOS battery may differ among motherboards.

- Put Battery Back: Put the CMOS battery back in place while ensuring its smaller side faces down.
Your BIOS settings will automatically reset once you’ve returned the CMOS battery. You can reattach the PC case cover and restart it.
Final Thoughts
These are all the fixes that I recommend you try to fix the ‘computer turns on but no signal to monitor’ issue. Hopefully, trying out another displaying device, updating drivers, checking GPU, or resetting the BIOS settings will help eliminate your issue.
If none of the fixes work for you, you can try heading to a professional who can look at your computer and conduct a deeper analysis and diagnosis. You will be informed of the real reason behind the issue and will be told the fix it accordingly.
In newer computers, finding a VGA cable slot may be difficult. However, you can check both via VGA cable if your PC and monitor are older. Frequently Asked Questions
