Are you frustrated with your Acer computer displaying a “no signal” message? You’re not alone. This issue can be caused by a variety of factors, ranging from loose connections to hardware problems. In this article, we’ll explore the possible reasons behind this issue and provide step-by-step solutions to help you resolve it.
Understanding the “No Signal” Error
The “no signal” error on your Acer computer typically indicates that the display is not receiving any video signal from the graphics card. This can be a hardware or software issue, and it’s essential to identify the root cause to fix the problem.
Common Causes of the “No Signal” Error
Before we dive into the troubleshooting steps, let’s take a look at some common causes of the “no signal” error:
- Loose or faulty video cables
- Incorrect display settings
- Graphics card issues
- Monitor problems
- Outdated drivers

Troubleshooting Steps
Now that we’ve identified some common causes, let’s move on to the troubleshooting steps.
Step 1: Check the Video Cables
The first step is to check the video cables connected to your Acer computer. Ensure that the cables are securely plugged into both the computer and the monitor. Try wiggling the cables gently to see if the signal is restored. If you’re using a VGA cable, try switching to a different port or using a different cable.
Types of Video Cables
- VGA (Video Graphics Array)
- HDMI (High-Definition Multimedia Interface)
- DisplayPort
- DVI (Digital Visual Interface)
Step 2: Adjust the Display Settings
Sometimes, the “no signal” error can be caused by incorrect display settings. Try adjusting the display settings on your Acer computer:
- Press the Windows key + P to open the Projector window.
- Select the correct display output (e.g., VGA, HDMI, etc.).
- Ensure that the display is set to the correct input (e.g., HDMI 1, VGA, etc.).
Step 3: Update Graphics Drivers
Outdated graphics drivers can cause the “no signal” error. Update your graphics drivers to the latest version:
- Go to the Acer website and search for graphics drivers for your specific model.
- Download and install the latest drivers.
- Restart your computer and check if the issue is resolved.
Step 4: Disable and Re-enable the Graphics Card
Disabling and re-enabling the graphics card can sometimes resolve the issue:
- Press the Windows key + X and select Device Manager.
- Expand the Display Adapters section.
- Right-click on the graphics card and select Disable device.
- Wait for 10 seconds and then enable the device again.
Step 5: Check the Monitor
If you’re using an external monitor, try connecting it to a different computer to see if the issue persists. If the monitor is not working on another computer, it may be faulty.
Step 6: Check the BIOS Settings
The BIOS settings can sometimes cause the “no signal” error. Check the BIOS settings on your Acer computer:
- Restart your computer and press the F2 key to enter the BIOS settings.
- Ensure that the graphics card is set as the primary display device.
- Save the changes and exit the BIOS settings.
Advanced Troubleshooting Steps
If the above steps don’t resolve the issue, you may need to perform some advanced troubleshooting steps.
Step 1: Run a System File Checker
A corrupted system file can cause the “no signal” error. Run a System File Checker to scan and replace corrupted files:
- Press the Windows key + X and select Command Prompt (Admin).
- Type the command “sfc /scannow” and press Enter.
- Wait for the scan to complete and then restart your computer.
Step 2: Perform a System Restore
If you’ve recently installed new software or drivers, it may be causing the issue. Perform a System Restore to revert your computer to a previous state:
- Press the Windows key + S and type “System Restore.”
- Select the System Restore option and follow the prompts.
- Choose a restore point from a date when your computer was working correctly.

What are the common causes of no signal on an Acer computer?
The common causes of no signal on an Acer computer include loose or faulty video cables, incorrect display settings, outdated graphics drivers, malfunctioning graphics cards, and issues with the computer’s motherboard. It’s also possible that the monitor itself is faulty or not compatible with the computer.
To troubleshoot the issue, start by checking the video cables and ensuring they are securely connected to both the computer and the monitor. If the cables are loose, try tightening them or replacing them if they are damaged. You can also try using a different video cable or port to rule out any issues with the current setup.
How do I troubleshoot the video cable connection?
To troubleshoot the video cable connection, start by turning off the computer and the monitor. Then, unplug the video cable from both the computer and the monitor. Inspect the cable for any signs of damage, such as frays or cuts. If the cable is damaged, try replacing it with a new one.
Once you’ve inspected the cable, plug it back into both the computer and the monitor. Make sure it’s securely connected to both devices. Turn on the computer and the monitor, and check if the signal is restored. If the issue persists, try using a different video cable or port to rule out any issues with the current setup.
What if the issue is with the display settings?
If the issue is with the display settings, it’s possible that the computer is set to output the signal to a different display or port. To troubleshoot this, go to the computer’s display settings and ensure that the correct display is selected. You can do this by pressing the Windows key + P and selecting the correct display.
If the issue persists, try adjusting the display settings to see if it resolves the issue. You can also try resetting the display settings to their default values. To do this, go to the computer’s display settings and click on the “Reset” button. This will restore the display settings to their default values.
How do I update the graphics drivers?
To update the graphics drivers, go to the computer’s device manager and expand the “Display Adapters” section. Right-click on the graphics driver and select “Update driver”. This will search for any available updates and install them.
Alternatively, you can also update the graphics drivers through the computer’s manufacturer website. Simply go to the website, select the correct model of your computer, and download the latest graphics drivers. Follow the installation instructions to install the updated drivers.
What if the issue is with the graphics card?
If the issue is with the graphics card, it’s possible that it’s malfunctioning or not compatible with the computer. To troubleshoot this, try removing any external graphics cards and see if the issue persists. If the issue is resolved, it’s likely that the external graphics card is the cause of the problem.
If the issue persists, it’s possible that the integrated graphics card is malfunctioning. In this case, you may need to replace the graphics card or the entire motherboard. It’s recommended to seek the help of a professional if you’re not comfortable with replacing hardware components.
How do I reset the BIOS settings?
To reset the BIOS settings, restart the computer and press the key to enter the BIOS setup (usually F2, F12, or Del). Once in the BIOS setup, navigate to the “Advanced” or “Settings” tab and look for the “Reset to Default” or “Load Optimized Defaults” option. Select this option and save the changes.
Once you’ve reset the BIOS settings, exit the BIOS setup and restart the computer. This will restore the BIOS settings to their default values. If the issue persists, it’s possible that there’s a hardware issue that needs to be addressed.
What if none of the troubleshooting steps resolve the issue?
If none of the troubleshooting steps resolve the issue, it’s possible that there’s a hardware issue that needs to be addressed. In this case, it’s recommended to seek the help of a professional who can diagnose and repair the issue. They may need to replace the motherboard, graphics card, or other hardware components to resolve the issue.
It’s also possible that the issue is with the monitor itself. Try using a different monitor to rule out any issues with the current one. If the issue persists, it’s likely that there’s a hardware issue with the computer that needs to be addressed.
