Computer Turns On But No Signal to Monitor – [FIXED]

Computer Turns On But No Signal to Monitor

Computers and their usage never come free of glitches. One way or another we all have encountered weird connections or display problems that can easily make us lose our temper!

Some of the pc problems such as overheating or connection issues can be solved from the internal settings however when the computer turns on but there is no signal to monitor you won’t be able to do work any further.

No display from the monitor is a problem but the good news is there are multiple solutions to that that you can opt for. If one solution doesn’t bring you positive results you can certainly try another one and that makes things more optimistic.

So, what does that happen in the first place, and is there any solution to it?

Here’s How to Fix a Computer That Turns ON But No Signal To Monitor

You are working on the computer and there is no display signal to the monitor? It is frustrating and delays working. Here is what you can possibly do for the solution!

Make Sure it’s Turned On

If I ask you if your monitor turns on, you will probably laugh at the question! Certainly, the monitor is on but the display isn’t appearing and that is the problem.

However, in many cases, the monitor doesn’t get the proper power from the cable connection and that results in a blank screen. Normally, we don’t check the cable connection before switching on the PC, and that sometimes results in a poor display or maybe no display at all. So, double-check the cable connection before you start to worry.

Check the Display

If the VGA and power cables are properly connected, most probably, the issue would be with the monitor. For confirmation, you can test another monitor. Try connecting your computer with another monitor and check if the problem still persists or not.

Cable Check

VGA Cable Check

If another monitor is also not showcasing the display, you need to check the power supply and the cable for its ideal insertion. In this check, the power cable needs to be efficient and make sure there is no breakage or tear in it. If the cables are chewed or ripped by some rodents, you have your answer on why there is no display on the screen.

If cables are not broken, there could be some dirt or rust build-up in the port. This is another less likely parameter that many people often forget. Make sure the cleaning and snug fitting to get the display right on.

Detach the Devices

Sometimes, the excessive use of dongle devices can cause weird errors. If your monitor has been embedded with various external devices it can be before the screen to output smoothly.

Multiple inputs simultaneously can make any PC device underperform. Therefore, when it comes to fixing the problem, detach the external devices including, the webcam, internet cable, speakers, headphones, USB, etc., and try turning it on.

However, the process can take a few minutes to configure the setting and you may need to restart it once more. This should work if the monitor is not faulty.

Restart the Display Screen

In most cases, restoring the system makes enough difference to keep going on. Even if you are facing issues or random hanging, restarting it mostly solves major glitches.

So if your computer is turned on but there is no signal to the monitor, unplug the power cord and VGA cable and wait for at least 30 seconds. After that, plug in the wires properly and try turning it on. It should work now.

Still No Display to the Screen- Go for Troubleshooting

Luckily, there are some other troubleshooting methods that will help you get the display back. Now that you have checked out the possible ways of displaying cable and its performance, it is time to check out your computer.

1. The beeping sound

Pay heed if you are listening to a computer beep sound when you turn it on. Also, look if there are any light indicators or not. The beeping sound from the computer tells you about the wobbly component insertion. The graphics card or the RAM may not be fixed properly. Also, the fans need to work properly because the heat build-up prevents the display from appearing.

2. Observe keenly

If the monitor is powered on but there is no display, it can give you a lot of information about the real glitch. First of all, there are chances that your monitor itself is faulty and it’s time to replace it. Secondly, you need to closely observe the display message that appears on the monitor screen. 

The powered-on monitor with no display also indicates that the monitor is getting a signal from the computer but the operating system (OS) is experiencing some glitch. Therefore, you will require to install a Windows or Mac, whatever you are using!

3. Set the resolution

If the computer is working fine with another monitor screen, make sure the resolution is set accordingly. If the resolution is not supported by the monitor, the display glitch is bound to occur.

Other Possible Solutions

Once you have verified the power supply and proper cable insertion. The monitor should let out the display. However, in other scenarios, you need to clear the CMOS memory and make sure the voltage is not fluctuating. Furthermore, you should also reinstall and attach the RAM and other essential components of the PC. Mostly, if you clean up the RAM and reinstall in the same to some other slot, the display glitches get resolved.

Unlikely Reason For No Display

If the power supply is bad at supplying enough power to the display, there can be issues like fluctuating screen or even no display at all. This is because the graphics card and CPU are not working together to let out consistency in current. The insufficient graphics card supply can also impact the display monitor. So make sure both of these parameters are resolved.
