The most common cause of your Acer monitor blinking on and off is the most basic and easily fixed issue. Your monitor’s cable must be loose.

Take a look at the back of your display before taking advanced, costly, or complicated measures to fix it and make sure the cable is properly inserted in the port.

The display could be continuously blinking on and off due to a faulty video cable, as well. You can test this by connecting your computer to your monitor with a different cable.

You should just replace your faulty, old cable with a new one if it works fine.

Extending/Power Strips Are Too Loaded

It is possible that your monitor is not receiving enough power, causing it to blink on and off. If this is the case, you can either:

  • Remove any unnecessary devices from your power strip. Only leave your monitor and computer on.
  • The monitor can be disconnected and plugged into a separate extension cord/power strip if all the devices connected to the power strip are essential.

An Incorrect Power Supply

If Your Acer Screen Is Blinking On And Off For No Apparent Reason, This Is A Possible Cause. That Your Acer Screen Is Blinking On And Off.

There are different standard single-phase voltages in different countries around the world. Typically, countries in the Americas have a 120V standard voltage, while countries on the right side of the map, like Asia and Australia, usually have a 220V to 240V standard voltage. Europe is no different.

In other words, you won’t be able to run a 120V monitor from a 220V outlet. In order to make it work, you need a voltage transformer.

A 220V monitor can, however, be powered by a 240V supply. It is possible to run a 220/230/240V monitor from any of these voltage supplies.

Even though this is not normally considered dangerous or to be avoided, it could be causing issues in your device.

It is recommended that you use a transformer if you are running your monitor at a voltage different from what it is rated for in order to avoid this type of problem later on.

Low Refresh Rate

There is a bit of a trend on the internet when it comes to this topic.

Many users and experts believe that a low refresh rate can be responsible for a blinking monitor.

Monitor refresh rates should be between 60Hz and 75Hz. Basically, this means the screen refreshes itself 60 times every second.

Your monitor may appear to flicker or blink if this rate is set too low. Here are the steps that you can take to adjust the refresh rate:

  • Open ‘Settings’ by pressing Windows + I.
  • Choose ‘System’.
  • Scroll down until you see the ‘Advanced display settings’ under the ‘Display’ menu. The option will be located just above ‘Graphics settings’ at the bottom of the page.
  • The ‘Choose display’ section of the menu will allow you to select your display from the drop-down menu.
  • From the drop-down menu in the ‘Refresh Rate’ section, choose a higher refresh rate.

Miscellaneous Hardware Issues

Any of the solutions mentioned above may not solve your problem, meaning that the port on the PC or the monitor may be malfunctioning. The problem might even be deeper – like a graphics card issue.

The best way to fix these types of issues is to just pick up your stuff and take it to a reputable repair shop.
