How To Fix Acer Monitor No Signal Issue
Check The Cable Connections
As explained above, the No Signal issue on a monitor can be caused by improper cable connections. The first thing that you need to check is your cable connections. Try the following things to see if the problem is resolved:
- Verify that the cable is not loose.
- Connect the video cable to the monitor and computer again after unplugging it.
- The No Signal issue is caused by the monitor not being connected to the right video source. Multi-input monitors generally suffer from this problem. Connect the video cable to the correct source if multiple computers are connected to one monitor.
Check Your Cable
Even if you have connected the cable correctly, your cable may be damaged if the No Signal issue still persists on your monitor. It might help to connect your computer to another monitor and see if the issue persists.
Check Your Video Source and Monitor
You might have turned on the monitor but not turned on your computer. When the monitor does not receive a valid video signal from a computer or source, it displays a No Signal message. Therefore, please check whether your computer is on or not.
In the event that your computer is on and you have checked your cable and connection, but there is still no signal, either your computer or your monitor is malfunctioning. Try these steps:
- Connect another display to your computer.
- Connect the same display to another computer.
Reset Your System BIOS To Default

Please navigate to the Boot settings section on the main screen and set it to boot from the hard disk. Open your laptop and press the F1 key during booting. Then, you need to navigate to the advanced options page and then press Enter to enter into the BIOS setup. Try to restart your laptop and if the problem is still present, then repeat the steps mentioned above.
