How to Fix Monitor No Signal? Quick Ways

Just now I acknowledged you with the reasons that lead to monitoring no signal problem. Well, as there is more than one cause of this error, the ways to fix this are many as well.

Therefore, here are the easiest troubleshooting methods to help you resolve your issue.

1. Examine the Ports and Cables

Don’t go on and start with something extreme like dismantling all the parts and all. The first thing I need you to do is carefully and thoroughly inspect all the cables connected to the monitor and processor.

Regarding the fact DisplayPort, HDMI, and DVI cables and ports are connectors making your monitor get signal.

Thus, here are the following steps –

Turn off the monitor and the power sources.
Now, disconnect all the input source cables responsible for providing the signal to the monitor.
Look out for each and all of the cables that seem damaged, run-down, or not working. If you find any of the cables with flaws, replace them.
Again, recheck the cables/ports and, in the meantime, clean up the clogged-up clouds of dust or residues hampering the connection.
After that, re-plug the cables in the right input ports. And then try to turn on the monitor to check for a signal.
If the monitor still doesn’t work, try to examine each cable individually to find which cable is nonresponsive. (You can try out the cables on another monitor/laptop).
In case you found the cable with flaws, replace it, and you are good to get a signal in the monitor.

If this method succeeds on your end, congrats! Also, you don’t need to follow through with the other effective ways below.

But, if not, don’t worry, you are not the only one. Let us proceed to try out other alternative solutions.

2. Inspect the Display Resolution Configuration

This method may seem a bit, but it is worth a shot. That’s why, before turning on your PC monitor, you better check the display resolution configuration. In case you mistakenly set (Graphics Cards) GPU’s resolution higher than its Refresh Rate, it’ll fail to get a signal.

Therefore, to correctly set the resolution to the compatible one, try to boot up the monitor to safe mode. This will change the resolution settings to the higher, lower, or accurately compatible ones. Also, this will bypass the issues of lower or lagging monitor resolution.

If you are unsure about the resolution type to be compatible with your monitor, you can simply go through the user manual notebook. Perhaps, you can also search up on google like “What is the resolution of my PC monitor?” . Just make sure you include the model type and number while searching for the accurate resolutions.

After that, you should simply follow these instructions below:

Start by going to the windows Setting’s Menu.
Now, enter the System, and from there go to the Display.
Inside the display, enter the Display Resolution.
Now, you can change the Resolution as you prefer. (All the resolutions available in the options are compatible with the system. So, you do not need to worry about configuration errors.)
Thus, click the Keep Changes from the popup question “Keep these display settings?” . And you are good to go.

This method is good enough to fix your issue and give you a monitor signal.

3. Reset The PC Monitor Display

Resetting the monitor will eventually restore the monitor to its initial system as well as get rid of all of the bugs and problems.

The process of resetting a monitor is very easy. However, the reset process may be different depending on the individual manufacturers’ monitors. You can either search for the method of resetting the monitor in their online support forum.

Or else, you can also reboot the monitor just by using old-school methods. Restart->Shut Down->Reboot->Turn On. Thus, all the display settings will revert to the initial default settings.

4. Check The Display Adapters

If everything else is alright and you Amare working with the adapter, check it thoroughly. The display adapter can become faulty and stop the signal from reaching the monitor.

You can take off the adapters from your monitor and processor.
After that, test them on a different monitor (borrow your friends’ monitor) to check whether they are alright or broken.

5. Try Changing Input Sources

Sometimes, you mistakenly insert the ports and adapters into the wrong input sources. Therefore, all the monitors come with many input sources for no apparent reason.

And that is why it is not unusual for you to set your display input ports inside the wrong input sources. Also, it will lead to terrific signal issues; sometimes, other sources will fail to work.

Therefore, I will show you a simple method to check the input sources and change them if necessary.

Go to the Settings and from there enter the Display Inside there, search for the input Source option. (You can also use the search bar for direct access.)
After going inside the Input Source option, you will find versatile options and details about every input source. (In monitors with different configuration settings, you will find the button on the side to check through all the options instead of the hover option.)
You need to set your monitor input-output sources to the correct one. For instance, in case your monitor to the device connection is set up using HDMI, you will be needing to set the HDMI in the output source.

6. Examine the Issues Using Another Monitor/Device

If you have tried all the methods so far but in vain, you should check the monitor itself. As you have examined, the cables, ports, adapters, and input sources are all in check. However, if the monitor is still showing, there must be some underlying error within the monitor.

Therefore, to test the monitor signal using another monitor, here are the steps –

Disconnect the monitor with no signal and connect the new monitor or device to the system.
Now, reconnect the adapters, connectors, ports, and input cables as per requirements.
Now, start the monitor to check if it will work and get the display signal.
If the newly connected monitor works fine, then your old desktop monitor is damaged somehow. You should take it to the repairs provided by the manufacturer.
In most cases, the warranty will cover most of your expenses unless you need to switch to a new monitor.
Oh right, before you think about replacing the old monitor with a new one, you should consider troubleshooting your whole PC. Lastly, try all of our methods to avail the least bad outcome.

7. Update The Out-of-Date Drivers

We all know from experience that outdated drivers can lead to many issues. Therefore, we all faced stuttering and ghosting. Besides, outdated drivers can cause no signal issues apart from these issues.

So, here is the method to update the drivers to the latest versions.

Right-click the mouse on Start.
Now, use the search engine to look for the device manager and enter (you can also go through the settings).
After that, scroll through the Categories to find the drivers that required updating.
You will see the Display Adapter drivers you need to update. Right-click on the Intel display adapter and again click on the update drivers.

8. Hard Reset and Reset CMOS

I’m case you are not finding any solution even after trying all the instructions above, then the last reset is to hard reset your PC. And by hard reset, I mean resetting the CMOS.

First, shut down your PC, and thoroughly pull out all the connection cables and ports.
After that, open the case to find the CMOS battery inside it.
Now, you need to remove the battery out from the motherboard carefully. (Well, it is not recommended by the manufacturers. But it is worth the chances).
Then, wait on the battery for 4 or 5 minutes and then set the CMOS battery back in its case.
Or you can also replace the CMOS battery while following the in-depth guidelines in the user manual.

Cautious: If you are unable to open the case using basic screws, then do not perform this task. Moreover, this task may be a different experience every time depending varieties of devices.

9. Test and Check PC Hardware

After all the troubles you went through to execute all the methods, the monitor signal should return already. However, if the error is still there, the final and last resort is that something is wrong with your PC or monitor hardware.

Therefore, as a PC is a complex device, even a slight fault in a tiny component can make a lot of side effects.

Start by, examining the loose components, open the case and check for loose or faulty parts one by one. If you find one, tighten or reattach the components.
Next, you should also inspect the GPU and CPU while you are examining thoroughly. And to check for burned or damaged parts and replace them as well.
Lastly, as it is a monitor with no signal issue, perhaps the error lies elsewhere. So, check the RAM sticks, PSI, and Motherboard.

After doing these steps, if your monitor does not have any signal till now, I think your monitor is dying. So, you should replace it and buy a new monitor as soon as possible.
