Acer Monitor Blinking Blue Light [Reasons & Solutions]

I have been using an Acer monitor for a few months and never faced any issues until yesterday when it began blinking blue light. 

I didn’t understand what this meant so I did research online and figured out what the problem was and thankfully I successfully fixed it. 

So, if your Acer monitor is also blinking blue light, you should try the troubleshooting guide below.

Why is my Acer Monitor Blue Light Blinking?

If you have an Acer monitor and the blue light is blinking, it could be because of a faulty power cable or HDMI cable connection, an incorrect power setting such as a Power Cycle or Power Saver Mode enabled on your monitor’s menu settings, or even due to an outdated driver

To troubleshoot this issue the first step would be to try plugging in different cables and sockets to ensure that there is not a bad connection causing the problem. 

Also, try turning off any power saver mode if enabled on your monitor’s menu settings. 

It is also worth considering restarting the system after making changes before trying again to see if that helps resolve the issue.

How to Fix Acer Monitor Blue Light Blinking?

1. Faulty Power Cable

Faulty or broken power cables can often be the culprit when your Acer monitor blinks blue light. 

Over time, power cables can become worn or damaged due to bending, stretching or mishandling. 

If your power cable is not connected securely to the monitor, this could cause an intermittent connection and result in a blinking blue light. 

In addition, if the cable has suffered any sort of physical damage over time, such as exposed wiring, you must replace it immediately to prevent further complications. 

You should check all your power cables for fraying or wear every few months in order to keep them secure and working correctly. 

If your blinking blue light issue is being caused by a faulty connection due to a poor power cable then you must immediately replace it to prevent further problems.

2. Faulty HDMI Cable

When your Acer monitor starts blinking blue light, there’s a good chance that the cause is a faulty or broken HDMI cable. 

Over time, HDMI cables can get damaged due to wear and tear as they are prone to fraying, crushing and even corrosion. 

This deterioration can lead to problems such as the blue light blinking if the connection between your monitor and the HDMI port is not secure enough. 

Check if your HDMI cable is properly connected to the monitor to solve this issue. 

Loose connections may be a major cause of this problem, so ensure that each end of the cable is firmly secured before trying anything else.

If the connection appears to be fine, but you still encounter issues with the monitor flashing blue light, it may be time to invest in a new HDMI cable. 

In most cases, a faulty or outdated cable might be causing these kinds of problems. Check if your existing cable version supports your monitor’s necessary data transfer speeds. 

Otherwise, look for an upgraded version that meets its requirements. Ensure it’s compatible with both devices before purchasing – some older monitors might require different specifications than newer models.

3. Power Cycle Acer Monitor

Power cycling your Acer monitor can help you fix several issues

Power cycling is a process that involves completely shutting down the device before restarting it again. 

This helps clear out any temporary data stored in its memory and refreshes any settings or configurations that may have become corrupt.

To power cycle, your Acer monitor, start by unplugging the power cord from both the wall outlet and the monitor itself. 

Next, press and hold down the monitor’s power button for 30 seconds to ensure all residual energy has been discharged from the system. 

Finally, plug the power cord back into the wall outlet and monitor before turning on the device. 

If you see a solid blue light once it’s turned on, it indicates that the power cycle was successful.

Depending on your Acer model, you may need to reset all its settings to factory defaults after completing a power cycle. 

4. Try Different Power Socket

If you are experiencing your Acer monitor, one possible cause could be the old, and dusty power socket. 

Over time, the power socket can become old and dusty, damaging its circuitry. This can produce sparks, leading to the blue light on your Acer monitor flickering. 

To test if this is causing your issue, try unplugging your Acer monitor and plugging it into a different power socket. 

If you can access an alternative power source, such as a surge protector or UPS, try connecting it there instead to see if it resolves the issue.

If that doesn’t resolve the issue, dust buildup could be the cause. 

Disconnecting and cleaning out any dust from inside the power socket should help reduce any sparking which may be occurring due to contact with dirt or other particles. 

Additionally, make sure both the Acer monitor’s power cord and plug are in good condition – no fraying of wires or exposed metal parts should be present. 

5. Turn off Power Saver Mode

Power saver mode is a feature that can be enabled on Acer monitors to conserve power and reduce energy costs. 

Unfortunately, this feature may cause blue light to blink, which is an annoying issue that can disrupt your work or entertainment experience. 

If you’re still experiencing this issue, the 5th step is to try to turn off power saver mode by accessing the monitor settings menu.

To do so, press and hold the Menu button for at least 15 seconds until the main menu appears on screen. 

Then, use the arrow keys to navigate the menus and locate Power Management Mode. Select the option to turn off power saver mode. 

This should immediately stop the blue light from blinking once you’ve disabled it.

It’s important to note that while turning off power saver mode may fix this issue, it may also result in other problems due to a lack of energy efficiency. 

If this doesn’t resolve your problem, you’ll need to consider a different solution, such as driver updates.

6. Update Acer Monitor Driver

While updating your monitor driver can be an easy affair, it is important to follow all the necessary steps attentively. 

To start with, you have to check which driver version you are already running on your computer and then download the latest one from Acer’s website. 

After downloading the new driver file, you will need to unzip its contents and begin installation on your system. 

For Windows users in particular, these exact instructions for updating your monitor driver may vary depending on your Acer monitor model. 

But generally, you can follow these steps:

  1. Identify the model of your Acer monitors.
  2. Visit the Acer website and go to the “Support” section
  3. Find the “Downloads” or “Drivers” page 
  4. Search for your monitor’s model update.
  5. Download the latest driver for your operating system
  6. Follow the instructions on the screen
  7. Restart your Acer monitor

When updating Acer monitor drivers, it is important to remember to back up all important files before starting, as processes like this can sometimes interfere with existing data or settings on computers or laptops. 


If your Acer monitors blinking blue light, you should try these troubleshooting steps.

  1. Check Power Cable
  2. Check HDMI Cable
  3. Power Cycle your Acer Monitor
  4. Try Different Power Socket
  5. Turn off Power Saver Mode
  6. Update Acer Monitor Driver

If you have tried all these steps and your monitor is still blinking blue light, then you should contact the Acer support team. 

They have experts who can help you to fix this problem.

However, if everything goes in vain, I suggest buying a new Acer monitor.
