Why My Monitor Is Saying “No Signal”?

Why My Monitor Is Saying "No Signal"?

When your organisation does not have an Information Technology department, it may fall on you to keep your computer systems running in the event of an error. If your screen is showing “No Input Signal,” there is no image displayed from your PC to your display. There are numerous possible causes for this error. To repair it, you should figure out which part is defective, ranging from the cable televisions that connect your display to your PC to the display itself and even your PC’s video card.

1. Shut off your computer.

2. Unplug the cable television running from your monitor to your PC and plug it back in, making certain the connection is firm. The most typical reason for this error is a loose cable.

3. Reattach the cable running from your screen to your PC. If the monitor is still not displaying a signal after strongly reattaching the cable television, the issue might lie with the cable television, especially if the cable has noticeable damage.

4. Replace your screen with another display if possible. If the “No Input Signal” error still appears, the issue does not rest with the cables or the display, however with your PC.

5. Open your PC case and find your video card. Remove the card and after that change it strongly in its slot or, if possible, insert the video card into another slot on your motherboard. A video card that is not making a firm connection will not display images to the screen. Close your PC case and test the display once again.

6. Change your video card completely. Your video card may struggle with internal damage that is not enabling it to output a signal.

Tips

If you are still not getting a signal even after changing your video card, you may also need to replace the computer system’s power supply and, in a worst-case situation, your computer system’s motherboard.
If your computer system is still under service warranty, schedule an official repair before you open your computer. Frequently, opening your computer system yourself will void your warranty.

Warning

Always ground yourself by touching a metal object prior to touching any part in your PC case. Failure to properly ground yourself can lead to damaged components.
