How To Fix No signal Monitor Or No Computer Display [ 9 Simple & Easy Ways ] 

The most common error found on old PC systems is no signal monitor, which means the monitors are not receiving signal/power from the CPU. This error with the monitor is displayed as No signal to the monitor.

The No Signal Monitor has been the most frustrating thing you ever experience on a PC because the main hardware works properly, but the monitor is not powered. 

There are many reasons for this error. We can resolve it easily if it is in our hands. 

Some of the reasons are as follows.

  • The power cable is not properly inserted. 
  • Monitor cable fault. 
  • The cable wire is loose.
  • The pins are not working properly. 
  • Power from the CPU to the monitor cable is not sufficient.
  • The monitor is not under conditions.
  • Driver issues

These are some of the main reasons. 

Know About No signal Monitor Or No Computer Display

Computers have played a major part in our daily lives since their launch. We can witness drastic transformations in a computer’s hardware and software technology. On the other hand, sometimes we face errors that have been showing up while using. One such error is, No signal monitor. 

No signal for the monitor would appear for various reasons, such as when the cable wire is loose, no power is detected for the monitor, damaged cables, the driver’s fault, or any hardware issues. Those faults can be rectified easily on your own. 

If the damage is within the cables, you must remove and insert them properly. If the issue is not rectified through this method, go and get a new cable and try again. Check all the possibilities mentioned above, and finally, take your monitor to the hardware shop if the problem is not resolved.

Most reasons for the error, ‘No signal monitor,’ are not serious, but we can easily adjust them. 

In this article, we will explain how to rectify the error ‘No Signal Monitor.’ Read further and check out the possibilities for the error.

1. Check the adapter pin

Check the adapter pin in the CPU. Check whether it is properly inserted and try to remove and reinsert the pin. If the adapter pin is improperly inserted or becomes loose, the error shows no signal monitor.

If the problem is not resolved even after repeatedly doing it, the adapter is damaged or useless. Try to get a new adapter and fix it.

2. Check the power cable and reinsert it

The main important fault might be with the power cable. Before you get stressed or panicked about the reason, unplug the power cable and try to reinsert it.

If the problem lies in the power cable, it will get sorted. If the power cable is not working properly, then try to change the new cable and try the same. The problem will be resolved. 

3. Check the monitor input cables

Another important thing you must check for is you have to re-insert the monitor cables too. There might be a loose contact, or the cables may get loose when we move out the monitor according to our will. Hence it will lead to insufficient power to the monitor, so the error no signal monitor will show up as no signal gets detected.

4. Test the cables in different devices

If you have tried the above methods and found no solution, try one more method.

  1. Check whether your cables are working on another device or not.
  2. Connect cables to any device, then check. If the cables work on another device, the problem is with the monitor itself.
  3. Try to change the monitor and check for the problem to be resolved.

Most often, the signal problem is not from the monitor. The monitor will work even when its display is broken. Here, we are talking about the signal not being connected somewhere. The problem may lie with cables, hardware, power systems, etc.

5. Check the hardware and replace it

You have checked all the preliminary fixes, cables, and power systems, but the error still exists. Now check for the hardware issue. Open your CPU and check whether the RAM, SD, and power adapter are properly connected and fix all the cables and try again.

If this method also doesn’t work, take your CPU and monitor to the hardware shop. Service providers will examine, and they will easily find the real cause of the problem. They will suggest changes if needed. 

6. Remove the CMOS battery and replace it

This is one of the easiest tricks to do. Inspect all the components first, and you may find a CMOS battery piece. Carefully remove it and hold it for a few seconds; before doing so, unplug all the cables, remove the CMOS battery, clean it, and replace it again in the same position carefully. Now fix all the cables again and check whether the input is working.

7. Change the resolution of the monitor as per the monitor standards

The monitor’s display resolution must be as per the PC output graphic standards. You cannot set a very high resolution other than the intended one. The monitor has an end resolution, and for the PC to have an end resolution, you must do as per the PC’s capabilities. Anything other than that will cause errors in the monitor.

8. Monitor reset

Resetting options are unavailable on many monitors, but few have such features to rest the option. The reset option is very simple; if you find it difficult to do, find you monitor the user manual and do it. If you don’t have a manual, follow the steps to your monitor manufacturing company’s main website. 

9. Drivers might be outdated

After discussing many reasons, another one may resolve the error of no signal monitor. 

Sometimes outdated drivers may corrupt the Windows OS. So, the signal is not detected by the system. Update the latest drivers of the PC now and then. You can update the system or OS if your monitor isn’t working. So, try to fix it with another monitor. 

Switch the power button and press F8 on your keyboard until you see the display. Open the OS in safe mode, select the highlight on safe mode, and press enter. After the system is opened in safe mode, press the Windows start button and give a right click on it; you may see some options. Now go to the device manager and search for the displaying adapters. 

Click on it, and you may see Intel UHD graphics, depending on the drivers and their manufacturers. Some have Intel, and some others have updated drivers. Come back and wait for some time and restart the PC again.
