Besides laptops, desktop computers are also devices used by many people. However, this device sometimes has some unknown problems. Specifically, there are many cases where when you turn on your computer, you see the text no video input. If you are also experiencing a situation where your computer says there is no video input, below is information for you.

What is the situation when the computer says there is no video input?

The computer error saying there is no video input is a common error that occurs with desktop computers. When a problem occurs, it means the image signal from the computer is not sent to the screen. At this time, the screen will not display any content except the message no video input. And of course, when we encounter an error, we will not be able to use the computer.

Cause of no video input error on the computer

According to my research, the computer having no video input error is due to many reasons. The following listed causes are the most common:

1/ The cable connecting the screen to the computer has a problem

To connect the computer to the screen, we must use a connection cable. When the connection cable has a problem, the signal from the computer will not be transmitted to the screen. Often it is possible that the cord has been used for a long time and is damaged. Or it could also be due to external influences such as fractures, mouse bites.

 2/ The connection port has a problem

Similar to cables, the connection port can also cause you to get a no video input error. This is because the connection port on the computer or screen is rusted, making the connection unreliable.

3/ Computer components have problems

The third cause of computer errors may be due to problems with certain components on the computer. These components can be CPU, RAM, SSD or power source. The most likely one is faulty Ram.

4/ VGA is broken

Ultimately, it is because the VGA on your computer is faulty or damaged. Specifically, VGA will be responsible for outputting images to the screen. If VGA is damaged, the screen will not receive data at this time. This is usually due to VGA overheating or the effects of time.

How you can handle no video input error on your computer quickly and effectively

Instead of panicking and worrying about the no video input error, you can try a few of the following methods. If you're lucky, you can still fix this annoying error yourself.

1/ Check the connection wire

First, try checking the connection wire from your computer to your monitor. If you notice that the wire shows signs of breakage or is too old, you can replace it with another connection wire to see if it works.

2/ Check the connection port

Next, check the connection port on your monitor and computer. If the connection port shows signs of rust, you can try using a brush to clean it. Or you can also use a specialized rust cleaning solution to clean the connection port. Do not use water or strong detergents such as gasoline to clean rust on the gate to avoid damage.

Or you can also try switching to another connection port to see if it works. Currently, most monitors and computers support many different connection ports. So try connecting to different ports one after another to see if it works.

3/ Check computer components

Usually, computer components are rarely damaged. But there are times when it won't work properly. Among them, RAM is the most common component with errors. Therefore you can try cleaning the ram and ram slot then restart the computer.

4/ Check VGA

Check to see if the VGA on your computer is working properly. If unfortunately the VGA is damaged, there is a high possibility that you will have to replace this component. Or if your computer has VGA onboard, you can also try unplugging the VGA and connecting it directly to the main board to see if it works.

5/ Check the screen

Finally if everything on the computer is fine. The last possibility is that your computer screen is broken. If possible, try connecting your computer to another screen to see if it works.

So we have just learned about the situation where the computer reports no video input. If this error is bothering you, immediately apply the methods introduced above to fix it!
