You’ve come to the correct spot if you’re having trouble with your PC’s display not receiving a signal.
You’re not alone in this, many people sometimes have the same or similar problem.
The no signal indication on the display means that your computer isn’t sending any input to the monitor.
With the remedies we’ve provided on this page, you can quickly repair this problem.
Make sure the video cable is securely attached
The monitor no signal problem is caused by a faulty connection between your computer’s monitor and that device.
When your Windows system is running and you receive a no signal notice, the first thing you should check is if your suitable video connection is firmly connected.
Try the following solution if your suitable video cable is firmly attached but the problem still exists.
Verify that you choose the right input source
You will also experience a problem with the display not receiving a signal if you didn’t choose the proper input source for your monitor.
You must be aware of the ports that both your PC and the monitor have before choosing the proper input source for your display.
To choose the proper input source for your display, follow the steps below:
- Make sure your computer and display are both on.
On the edge of your monitor, click the menu button.
- Choose the appropriate input source by navigating to Input Source.
Set the input source to VGA, for instance, if you connect your monitor to the PC’s VGA connection.
Verify that your graphics card is securely installed in the appropriate slot
If your graphics card is not tightly seated in its slot, you will also see the no signal warning.
You must confirm this by opening your computer casing.
Here’s how to go about it.
- Switch off your computer, then unplug all of its cables, including the power cord and any associated devices.
- Locate your graphics card by opening the computer casing.
Depending on the type of card in your computer, the graphics card may not be exactly where it should be.

- Your graphics card should be taken out of your motherboard and securely inserted into its slot.
- Connect your display to your PC by re-plugging the power line.
- Press and hold the power button for 30 to 60 seconds before reconnecting the power cord and turning the device on.

There are further solutions you can attempt.
Run tests on a different cable or PC
A broken video cable is another likely reason for the monitor not receiving a signal problem.
To determine whether the problem still exists, try using a new cable to connect your PC and display.
If not, your video cable is the problem.
Try connecting your display to another PC to see if the problem persists.
If the no-signal warning is still shown on your monitor, it may indicate that the monitor is the root of the problem.
