Samsung Monitor Blue Light Blinking [You Should Try This!]

1- Faulty Cable/Connection

Faulty cable/connection is a common cause of Samsung monitor blue light blinking.

This issue can occur when the cables connecting the monitor to other devices are loose, broken, or not connected properly.

A loose connection between the video card and the monitor could also be responsible for this issue. 

Thus, it is important to make sure that all cables are firmly connected and no part of them has come undone.

Additionally, if using an HDMI cable, it’s important to make sure that it does not exceed the maximum supported length for reliable data transmission.

If the components of the monitor fail, then you will need to replace them with compatible parts to restore your display’s normal operations.

2- Disable Power Saving Mode

Disabling Power Saving Mode on a Samsung monitor can be done by accessing the menu settings of the device.

The menu option will typically be labeled “Power Settings”, and it can be found in the main menu or sub-menu of the monitor. 

In the Power Settings, one needs to find “Power Saving Mode” and switch it off.

This will stop the blue light from blinking and ensure that your monitor does not go into sleep mode unexpectedly. 

To make sure that your monitor is running optimally, it helps to disable Power Saving Mode from time to time. 

Doing so ensures that your screen is always displaying at its highest resolution without any energy-saving features interfering with this setting. 

3- Incompatible Resolution

When your Samsung monitor’s blue light begins blinking, it is likely due to an incompatible resolution. 

When this happens, the display output finds itself unable to match the desired resolution of any given content.

That makes it difficult to view the images and text on a given web page or application accurately. 

This can be caused by a range of factors such as incorrect monitor settings, or outdated graphics and video drivers. 

To resolve this issue, users should first check their system’s current resolution and then adjust it accordingly. 

If that doesn’t work then they should check their cables as well as update their graphics card driver to ensure compatibility with their display device. 

Once these steps have been completed, the blue light should no longer blink and users can enjoy their Samsung monitor once again.

4- Incompatible Refresh Rate

When a Samsung monitor’s blue light is blinking, it usually indicates an incompatible refresh rate. 

The monitor’s settings may be too high for the computer to process, which prevents the signal from being processed correctly. 

This can cause blurred images or other visual issues. To fix this issue, users must reduce the refresh rate in their system’s display settings. 

If the rate is too high, it will cause data to be skipped or distorted and result in poor picture quality. 

A lower refresh rate can help improve visuals by showing more frames per second (FPS).

To prevent this issue, users should make sure that their monitor’s settings match their PC’s graphics card capabilities.

5- Outdated Drivers

Outdated drivers are a common cause of Samsung monitor blue light blinking.

When this happens, the driver becomes outdated and may not work with your monitor correctly. 

To fix this issue, you should first check if any updates are available for your graphics card driver and install them if needed.

If that doesn’t help, try uninstalling and reinstalling the graphics card driver to get it up-to-date again. 

Additionally, make sure all other device drivers on your computer are also up-to-date so they don’t interfere with each other’s performance. 

6- Corrupted Capacitors

Corrupted capacitors are a common problem arising in Samsung monitors, as well as other electronic devices.

In this case, the bluish light that is typically seen when powering up the device is blinking instead of staying on continuously. 

This is caused by faulty or damaged capacitors located in the monitor’s power supply or voltage control circuit. 

The capacitors can become corrupted due to several factors including heat exposure, poor electrical connections, low-quality materials used during manufacturing, normal wear-and-tear over years of use, or even physical damage. 

To fix this issue, the failed capacitors have to be replaced with quality components that are resistant to heat and work efficiently under high loads.

Replacing capacitors may require special tools and some technical knowledge so it’s best left to professionals who understand what they’re doing.

7- Defective Power Supply

The defective power supply is a common cause of Samsung monitor blue light blinking. 

When the power supply has issues, it can either prevent the monitor from operating or cause strange behaviors such as flickering blue lights. 

A failed or failing power supply can result from several issues including loose connections, frayed cables, and faulty components inside the unit itself. 

To determine whether this is the culprit behind your monitor’s behavior, use a multimeter to check voltages at key points on the board.

If you find any that aren’t within an acceptable range then it is likely that your power supply needs replacing. 

Another symptom of a defective power supply is intermittent power loss. The monitor may turn on and off randomly with no signs of life in between.

If this occurs, then it is highly likely you have a malfunctioning power supply that needs to be replaced if you want to get your Samsung monitor back up and running again.

8- A Broken Monitor

When a Samsung monitor has a blue light blinking, it is typically an indication that the device is not functioning correctly. 

This could be due to several common causes, such as a bad connection between the monitor and the computer, or an issue with the power supply. 

In some cases, it might be caused by physical damage to the monitor itself, such as a crack in the LCD panel or a loose internal component. 

In these scenarios, it will likely require professional repair or replacement of parts to rectify the issue. 

Even if the cause of the blue blinking light isn’t immediately obvious, it’s important to have any issues with your Samsung monitor checked out by experts.


In conclusion, if your Samsung monitor is blinking blue light, you can troubleshoot this problem by following these steps:

  1. Faulty Cable/Connection
  2. Disable Power Saving Mode
