Since every monitor has a different set of options to work with, here are some basic settings that you should look for-

  • Input source selected (if you are using a multi-input monitor)
  • Display Settings (Set all of them to default)
  • Resolution (Ensure selected resolution is supported)

After you have made the changes, save them all and restart your computer. This should fix the input signal not found error for you. 

Fix 5 – Try Using a Different Monitor

If the above fixes could not help, try swapping the monitor. This will help you identify if the issue is with the monitor or the PC. If a different monitor works, the error is with the hardware you are using.

However, if the no signal on the monitor prompt is still there it can be the PC’s display settings. Follow the next fix to reset display settings.

Fix 6 – Check Screen Resolution Settings

After checking your monitor for issues, it is time to fix the screen resolution settings. When you are using a wider aspect ratio than your monitor can support you can face no signal issue. Also, there are multiple other settings that you need to pay attention to. 

Here’s how to do so – 

1 – Press Win+I to open the System settings on your PC.


2 – Click Display option at the top of the list in the settings.


3 – The Display settings offer many options to support the connected monitor. Check if the resolution and scale are set to match the metrics supported of your monitor.


4 – If you are using multiple output devices or a multi-display setup go to Advanced Display settings.


5 – Check and ensure that the source of your connected display is selected for the one you want to access. 

Since you have already checked the monitor configuration in one of the previous fixes, you know what resolution your monitor is capable of. Set the settings accordingly, and you should be good to go.  

Fix 7 – Update Graphics Drivers

At times the monitor no signal issue can be because of a faulty or outdated graphics drivers. Try updating the driver and see if it helps.

There are multiple ways in which you can update drivers on your PC.

Option 1. Update graphics driver manually

Graphics driver can be updated manually by visiting manufacturer’s website > searching for latest graphics card driver update.

When doing so ensure you select the correct Windows operating system and bit.

However, if this sounds tricky or you don’t have required technical skills you can do it automatically with Advanced Driver Updater. The tool finishes the updates for all the outdated drivers on your PC in just three steps – 

Step 1 – Download and install the tool from the link below. 

Step 2 – Run a scan for outdated drivers by clicking the Start Scan Now button.

Once the three steps are complete, restart your computer, to apply changes.

Updating drivers helps fix driver related issue and can also smoother the performance of your PC.

Note – If these fixes did not fix the issue for you, there are a few advanced fixes. We recommend trying them if you have computer skills. However, if you are unsure about any steps contact a professional who can help you with these. Please remember that the following fixes require you to open your CPU cabinet to check the components. 

Fix 8 – Check Graphics Card Placement

The graphics unit is the first thing you should look at after opening up your CPU. Since the display issues are directly related to the graphics, you should physically ensure that the unit is connected firmly and there is no damage to the surface of it. Here are the things to check for –

  • Check for loose connections in the unit.
  • Ensure that there’s no leakage of thermal insulation
  • If you are using liquid cooling, ensure it is not affecting the graphics performance.
  • Check if the heat generated by the intense use of graphics has damaged the unit.

Check for these problems; if any of these appear, you should get help from a professional to resolve them instantly. 

Fix 9 – Plug Out and Re-Plug RAM Sticks

The next thing to do is to check the RAM sticks. You can find them connected to the slot in the motherboard. There are multiple connections. Some require screws to be fixed, while others stick to the slot. Ensure that, in both cases, the connection is firm. 

Secondly, if you see a lot of dirt on the surface of it, there’s no harm in plugging it out and dusting it. Remove all the dirt and dust, clean the port, and connect the RAM sticks back.

Restart the PC again and check if the no signal error is resolved. 

Fix 10 –  Perform a CMOS Reset

The CMOS is a semiconductor device that powers your motherboard. The Complementary Metal-Oxide Semiconductor plays a crucial role in the functioning of the motherboard. However, if there’s an issue with the same, issues like the monitor not detecting the PC may appear. 

Resetting the CMOS can be of great help to you. Here’s how you can do the same – 

Please note that the steps are shown, considering that you have shut down the PC and removed all the cables from the device. It is really important to disconnect the power from the motherboard else it might harm your PC.

1 – Spot the CMOS (silver round battery-shaped) component on the motherboard.
2 – Carefully remove it from its slot
3 – Leave it unconnected for a good 5 to 10 minutes.
4 – Slap it back in the slot. Ensure you have brushed away the dust from the slot and the CMOS.
5 – After doing it all, close the cabinet and start your PC.

Other than these, you always have the option to get your motherboard checked for monitor support. Ensure these advanced fixes are only used if none of the basic ones work. Usually, the error is fixed easily as it is just a matter of connection and cables.
