One of the most common reasons for a Samsung monitor’s flickering blue light is a faulty cable or connection between the computer and the monitor. If the cable is loose or damaged, the monitor will blink a blue light.

2. Outdated Drivers

Sometimes, outdated display drivers can also cause this blinking blue light problem on a Samsung monitor. 

Display drivers allow the computer to communicate with the monitor. Without display drivers, the computer would not be able to send any information to the monitor. If they are outdated, it can lead to compatibility issues and result in the blinking problem.

3. Corrupted Capacitors

Capacitors are components inside the monitor that store electrical energy. If these capacitors become corrupted due to time or other factors, they can cause the monitor to blink the blue light.

4. Unsuitable Power Supply

Samsung monitors require a specific amount of electric power to function properly. If the power supply is not sufficient as per the requirements, then it can also result in the blue light blinking issue.

5. A Broken Monitor

7 Fixes for Samsung Monitor Blinking Blue Light

There are several ways to fix a Samsung monitor’s blinking blue light. 

1. Check for Damaged Cables

Before jumping into any solution, you should check your cables. The power cable can deteriorate with time, and it may not work properly. If the power cable is damaged or not working well with your computer, then make sure to fix it. If it still does not work, then you should buy a new cable.

Additionally, check whether your video I/O cables are working at full capacity. A simple way to check this is to swap out the cables or test the cables on another monitor. 

2. Check the Loose Cable Connection

Most of the time, a loose cable connection can cause the Samsung monitor to start blinking a blue light. To resolve this issue, check all the cables. 

If there is any loose cable connection, then tighten it and make sure that all the cables are plugged in properly from both ends.

3. Update the Display Driver

Outdated display drivers can cause compatibility problems, and as a result, your Samsung monitor will blink a blue light. Your monitors will only function properly if you use the most recent compatible display drivers. So, when your monitor is blinking a blue light, it’s probably because of outdated drivers.

However, the simple solution to this problem is to update the display driver to the latest version. You can visit the Samsung official website and can download the appropriate driver for your computer. You can follow these general steps to update the display drivers.

  • Search for Device Manager and then select it.
  • Now, click on the Display Adapter and expand it.
  • From the drop-down menu, click on the Update Driver.
  • Now, select Search Automatically for the Update.
  • If you get a message that the Driver is already installed, then click on Search for the Updated Driver on the Window Update.
  • Lastly, click on the Update button.

If updating the display drivers does not resolve this problem, then try another solution.

4. Reinstall the Display Driver

If, after updating, the problem still persists, then you should reinstall the display drivers. Sometimes, corrupted drivers might lead to the monitor to keep blinking blue lights. This means you would have to uninstall and reinstall the drivers.

Follow these steps to reinstall the display drivers.

  • Go to Device Manager and expand Display Adapters.
  • Right-click on the driver and click on Uninstall Device.
  • After uninstalling the drivers, Restart the monitor.
  • Now, again, go to Display Drivers and scan for hardware changes.
  • Windows will automatically scan and install the required driver. 

5. Adjust Power-Saving Settings

If your monitor goes into power-saving mode with unsuitable settings, then it also causes that blue light. In power-saving mode,  devices are designed to consume less power when they are not in use. This can reduce energy costs and extend the life of your device. 

So, adjust your computer’s power-saving settings to prevent the monitor from turning off too quickly. To do so, follow these steps:

  • Go to Control Panel.
  • Select the Power Options.
  • Now, choose the Balanced Power Plan.
  • You can also change settings by Clicking on Change Plan Settings.
  • Then, change these settings, “Turn off the display” and “Put the computer to Sleep” to Never.
  • Now, save all the changes.

6. Replace Your Monitor’s Capacitor

If the issue is still there, then the problem can be with the monitor’s capacitors. As capacitors age or swell, they cannot perform their functions properly. So, faulty capacitors can also cause the monitor to blink the blue light. 

In this case, it’s best to take your monitor to a nearby repair center and replace the faulty capacitors with professional help.

7. Perform a Power Reset

Sometimes a simple power reset can help you solve this issue. This setting will not delete any of your customized settings, but it will fix the blue light issue that you face on your Samsung monitor. To perform a simple power reset, follow these steps.

  • First of all, turn off your computer.
  • Then, unplug the power cables from your CPU and monitor. 
  • Also, disconnect all other cables from your monitor, like DVI, HDMI, power, etc.
  • Now, hold your monitor’s power button for about 30 seconds. 
  • Similarly, hold your CPU’s power button for about 45 seconds. 
  • Now, connect all the cables back into your system and turn on your monitor.
