Why is there no signal on my Acer monitor?
A No Signal message generally appears on your external monitor when it's turned on but not receiving any video input from the connected device. This could be due to a few reasons, usually simple connectivity issues or hardware malfunctions.
How to troubleshoot an Acer desktop monitor with no signal
Whether the problem is as simple as reconnecting your cable or as involved as updating the monitor’s drivers, we’ve got easy-to-follow steps for troubleshooting.
Power off and power on
The first and easiest step is to turn the monitor—and your computer—off and then back on.
Check or replace cables
Check all the cables connected to your monitor. Make sure the video cable connecting your Acer monitor to your laptop or desktop is securely plugged in at both ends.
You should also inspect the cable for any visible signs of damage. If you find any cuts or frayed sections, replace the cable and try connecting to the monitor again.
Inspect the monitor for physical damage
Physical damage to the monitor can also cause a no-signal issue. Look over the monitor for any signs of impact, including a cracked screen or damaged ports. If you find damage, the monitor may need repairs or replacement.
Verify the input
Monitors with multiple input sources need to be set to the correct input channel. Use the monitor’s on-screen menu to cycle through the available input channels until you find the one connected to your computer.
Check the label on the port where your cable is connected to confirm that you're on the right input.
Adjust the monitor and PC settings
Sometimes, external display settings on your computer might prevent the monitor from displaying an image. On your computer, navigate to Display Settings and make sure the monitor is recognized by your system.
Test with a different device or monitor
If you’re not sure whether the problem is with your computer or monitor, try connecting your computer to a different monitor. If it works, the problem may be with your original monitor.
Alternatively, you can connect a different computer or laptop to your Acer monitor to see whether the display works with another source.
Update the drivers and firmware
Outdated graphics drivers or monitor firmware can lead to compatibility issues. You can update your drivers by updating your software. If a software update is available, the drivers responsible for your monitor will be updated, too.
