How to fix VGA no signal issues: A definitive guide

You’re all keen to start that important computer work until you find the clear and eerie “VGA No signal” display. What this means: there’s no signal for your VGA monitor.

It’s not a time to panic – what VGA having no signal means is that the monitor is powered on but not connected to a video card. Your mission now is to ensure the connection is properly working.

Here is a thorough guide on how to fix VGA no signal issues quickly and easily:

Option 1: Troubleshoot hardware or connection issues

A hardware problem could be giving rise to the VGA no signal issue, so you have to make sure that the connector is plugged into the right port and isn’t pulled out too easily.

First, check the VGA port. Check if there is any damage or something inside the port is preventing VGA signal from getting through. Next, check if the cables are working properly; if necessary, replace them with another identical signal cable, e.g., HDMI or DVI, to conduct a cross test.

Try to push the connector even more until you feel the pins or pointed bits on the plug are well locked in place, not bent. In addition, plug another electrical equipment into the power outlet to check if the outlet is working normally.

Option 2: Is your computer merely sleeping?

Check if your computer has entered hibernation mode, sleep mode, or power-saving mode. This way, the monitor is unable to receive any signal even if it’s turned on.

To perform this check, press any key (the Enter key or Power key) on your keyboard, wait for a couple of seconds, and see if the computer wakes up. You may also move the mouse to wake it up. If it does, you have successfully resolved the VGA no signal glitch.

Option 3: Restart your devices

Sometimes all a computer system needs is a little jolt in the form of restarting and reconnecting the device. VGA no signal is one among many technical issues that can be addressed by this quick move.

Here are some steps to take:

  1. Turn off your computer and monitor. Unplug their power cables.
  2. Wait a few minutes. Afterwards, reconnect the VGA cable to the computer and monitor. Plug the power cable back, too.
  3. Turn on your computer and monitor and see if the VGA connection works just right.

Option 4: Update the graphics card driver

The VGA no signal problem can also stem from an outdated or missing graphics card driver, making it a must to keep it up to date at all times. If an update cannot be done right now, try HDMI or another kind of connection.

The latest version of the graphics card driver can be downloaded from the manufacturer’s website and installed onto the computer. If you don’t have the time and relevant skills to do so, you can rely on Auslogics Driver Updater, a tool that scans your system for the drivers on your PC that need an update.
