How to Fix VGA No Signal (Solved)

Regardless of the wide variety of input cables available, some computer users opt to use VGA cables. However, you should have no problems using a VGA cable if it is in good shape and the compatible connection it is used for. You can face the most common problem, “VGA No Signal.” This does not call for a scare because it can be easily fixed.

To fix VGA no signal, you must first conduct hardware troubleshooting because the problem mostly arises due to faulty cables and bad connections. Crosscheck for any lost connections and reconnect them. You can update your graphics card or boot the computer into safe mode. If you use a Mac, try resetting the NVRAM or using the hidden detect display feature. If you want to avoid such a problem occasionally, switch from VGA cables to HDMI cables, as they are better to use as input cables.

Do not be bothered so much if you face the issue, as it does not mean your monitor is faulty. In this article, I will show you how to fix VGA No signal with multiple fixes to try.

How to Fix VGA No Signal

What Does VGA No Signal Mean?

Although your display is on and using power, “VGA No Signal” signifies that it cannot recognize any video card or GPU too, it is attached to. It’s not a cause for concern, but it is a widespread problem, particularly when utilizing older connections like VGAs.

The notice has to do with your monitor and the wire that links it to your desktop; therefore, it’s not a sign that your computer is malfunctioning. After all, monitors are powerless on their own.

Reasons Why You Are Getting VGA No Signal Error

Depending on your circumstance, any of the following might be the cause of the error: 

  • Your computer’s GPU isn’t properly connected to the VGA wire.
  • Your computer display isn’t properly connected to the VGA wire.
  • The computer could be in hibernation mode.
  • The cable you are using is broken and has to be changed.
  • The GPU of the computer is attempting to output a resolution incompatible with your display.
  • Your computer’s GPU was set to the incorrect display output.
  • You selected the incorrect monitor input port.
  • An internal problem prevents your PC from booting.
  • There is a loose link between the two gadgets.
  • Your GPU is outdated.
  • Your display has a problem.

How to Fix VGA No Signal

The fixes to the VGA no signal problem are shown below. It shouldn’t be necessary to attempt each one; work your way through the list until everything is operational once again.

  • Investigate hardware issues
  • Reconnect cables properly
  • Verify whether it is in sleep, hibernation, or power-saving mode.
  • Update GPU
  • Boot the computer into safe mode
  • Use more modern cables for connection

For Mac Users:

  • Reset NVRAM
  • Employ the hidden detect display feature

Checking For Hardware Problems

Before anything further, it’s critical to realize that the “VGA No Signal” problem is essentially a connection-related one. Therefore, troubleshooting the cable of your computer should be your first line of action.

The most common cause of VGA no signal issues is a defective connection linked to a hardware issue. Therefore, check that the cable is in the proper port and cannot be removed easily. Examine the VGA port for damage as well.

Examine that port to determine if anything is preventing VGA from sending signals. Check the cables to see if they are functioning correctly. Change them if necessary. Fit the cable as best you can until the plug’s pointed ends lock it.

You can now attempt to power on your computer and display to determine whether the VGA no signal problem has been fixed or not. Alternatively, you can disconnect the VGA cable, wait a little while, reattach the cables, and then restart your computer.

Reconnect the Cables and Restart the Device

The input source for your display may not be connected to the appropriate device, which is another cause of the no-signal problem.

Since modern displays frequently have numerous accessible input connections, this is more typical. If this is the case, the issue should be resolved by ensuring your VGA cable is plugged into the VGA port.

Restarting your gadgets and connecting them again never hurts because it often solves technical problems. This can sometimes be sufficient to resolve problems like VGA no signal.

  • Unplug the power wires from your computer, monitor, and printer.
  • Wait a while, perhaps for about 10 minutes.
  • Reattach the VGA cable to your computer and display.
  • Reconnect the power cord.
  • Switch on your display and computer.

Your Computer Might Be In Hibernation Mode

Verify if your computer is in sleep, hibernation, or power-saving mode. In this manner, no signal may be received even with the monitor switched on.

Press the Enter key or the Power key on your keyboard, wait a few seconds, and then check to see whether the computer wakes up to conduct this test. To awaken it, you may also move the mouse. If so, you have effectively fixed the VGA no signal issue.

Update Your Computer’s GPU/Graphics Card Driver

Like many other pieces of technology, GPUs undergo regular upgrades, so a dated one may not function properly with your VGA cable and display. This is especially likely if the update in question was substantial.

The manufacturer’s website should be checked to see whether a new update is available if it has been some time since your last driver update. If so, obtaining and installing it ought to be simple and will solve your monitor’s signal problems.

As an alternative, you may configure your Device Manager to automatically update drivers if you’re using a Windows 10 or Windows 7 device: 

  • Access the search box on the taskbar and type in “Device manager.”
  • From the list of search results, select Device Manager.
  • In Device Manager, expand the Display Adapters selection and select Update driver.
  • Select “Search automatically for drivers” from the menu.

You may check your display settings to see whether the second monitor is being identified once the driver has been updated.

You may get feedback that your drivers are already current. You can check the driver provider’s website to determine whether your current version matches. Here’s how to go about it:

  • Like previously, right-click the display adapter.
  • Toggle to properties and click the driver tab.
  • The Driver Version and Driver Provider variables should be copied.
  • Paste the values into google search

Suppose your driver isn’t already up to date. In that case, you should locate the website of your driver supplier by using the procedures above. There, you may install the most recent version of the driver.

Boot The Computer Into Safe Mode

You can start your computer in safe mode and fix the issue from there if it persists. Find “Update and Security” in the Windows 10 “settings” app to accomplish this. Access recovery by searching for it in the taskbar search box >”Advanced Startup,” > “Restart now.”

The advanced starting box should then display, from which you may select “Troubleshoot,” “Advanced options,” “Startup settings,” and finally “, Restart.”

Click “F4” in the box that pops up to start your computer in “safe mode.” You may check to see whether the problem is still there once your computer booted into safe mode.

Reset NVRAM On Mac

Clicking the Apple logo in the upper left corner of the menu bar can help alleviate this issue if you’re seeing it on macOS.

Then select “System Preferences” and “Displays” from the menu. Hold down the “option” key on your Mac while you wait for a “Detect Displays” button to emerge.

Click it when it does to see if it resolves the issue.

Hidden Display Feature

Non-volatile random-access memory (NVRAM) corruption can occasionally occur, resulting in various technical problems. Fortunately, cleaning and resetting this should be simple.

Wait two to three minutes after shutting down your Mac. After that, turn it on and hit “Option” + “Command” + “P” + “R.” Holding down these buttons will cause the macOS to restart. Your Mac will now have cleaned the NVRAM, and you may proceed to see if the issue has been fixed.

Use Modern Input Cables

If the issue persists, it could be time for a complete upgrade. The fact is that there are better options available, and VGA is now an outdated technology. Sharper resolutions and higher refresh rates are made possible via cables like HDMI and DisplayPort. These cables are also more prevalent today and the norm for most contemporary displays.

Final Thoughts

If, after trying all the solutions mentioned above and none of them works for you, your monitor may be faulty, or the input port of the computer might be damaged. If you have enough to spare, you can replace the monitor. It is even better if the device is under warranty.
