Your Acer monitor displays nothing but the “No Signal” message, which means your monitor doesn’t receive a signal from the video card. What’s causing this issue? The reason could be a broken HDMI cable, a broken monitor, etc. Read on to learn the reasons and the possible solutions.
Following are the five possible solutions to the Acer monitor HDMI no signal issue. Click one of the links below then you’ll get the detailed instructions.
Tip: If you encounter the “No Signal” issue with your second monitor, you can learn the solutions from the post Easily Fix HDMI Monitor Not Detected Error.
Method 1: Check the connection
“No Signal” on a monitor means the connection between the monitor and the computer is loose. One of the possible reasons is that the HDMI cable is not plugged in right and not fully seated into the ports. To fix the issue, you can try to unplug the cable and re-plug it again.
1) Turn off your computer and your monitor.
2) Unplug the HDMI cable from both the monitor end and the computer end.
3) Wait a few minutes, like 5 minutes.
4) Re-plug the HDMI cable at both ends. Remember to make sure the cable is inserted firmly at both ends.
5) Turn on your computer and your monitor.
6) Check to see if the “No Signal” issue is resolved.
Method 2: Check the HDMI cable
A loose connection can be caused by a broken cable. Try with a different HDMI cable if possible. If the issue is gone while using the different cable, the original HDMI cable is broken. In that case, you need to replace the cable with a new one.
Method 3: Check the monitor
A broken monitor can also be the cause of the “No Signal” issue. If possible, connect the monitor to another computer and see if it works.
Alternatively, you can try with a different monitor and see if that monitor works on your computer.
After troubleshooting, you should be able to find either the monitor or the problem is the cause.
If the monitor is the cause, the monitor could be broken (then you’ll need to replace it with a new one) or the input source could not be selected correctly (see Method 4).
If the computer is the cause, you can try resetting BIOS to default (see Method 5).
Method 4: Check the input source
If the input source on your monitor is not selected correctly, the “No Signal” issue can occur. So make sure the input source is selected as HDMI on the monitor.
1) At the bottom of your monitor, press the Input button to enter the Input Source menu.
2) Check if HDMI is selected. If not, select it.
If you’re not sure how to check the input source on your monitor, you can download the User Manual of your product from Acer’s website to get the detailed steps on how to do it.
Method 5: Reset BIOS to default
The “No Signal” issue can occur if the integrated graphics card is disabled in BIOS. In that case, resetting BIOS to default can fix the issue.
You can refer to these steps to reset BIOS to default for your Acer product:
1) Restart your computer.
2) Once the first logo screen appears, keep pressing Delete until you enter BIOS.
3) Press F9 and then Enter to load the default configuration.
4) Press F10 and then Enter to save and exit.
Note: Modifying BIOS incorrectly can cause serious system issues. So be careful when you edit the settings in BIOS and ensure you know what you’re doing. Or you can contact Acer support for further assistance.
