If your video card fails, the output on the screen will suffer as a result, and blinking will occur. Various causes and solutions to how you can get away with screen blinking. 

Samsung Monitor Blinking Power Light

One or more LED indicator lights are commonly found on computer monitors, indicating the status of various devices. Manufacturers of monitors can program a series of signals, consisting of sequences of LED flashes and color changes, into the firmware of these devices’ circuit boards, acting as a secret Morse code to warn you to hardware, connection, and electrical issues. You can understand and respond to your monitor’s blink warnings once you know the codes.

LCD monitors are a great low-cost, low-power solution to our demand for a computer display when compared to earlier displays. They are better in quality and give an amazing experience to the user, some monitor settings, however, might cause an LCD screen to flicker because at once there are many LED screens 

A screen with blinking monitor can be more than just an irritation, a flickering LCD monitor can be dangerous. It can cause visual fatigue, migraines, and a variety of other problems, particularly if you spend a lot of time in front of the computer. Fortunately, you may take certain actions to stop the flickering and get rid of these issues. 

Why Does a Monitor Screen Blink? 

Your monitor refreshes at a fast rate to make it appear as if things are moving smoothly on the screen, much like a film strip is essentially a lot of static images displayed quickly. 

Hertz is the unit of measurement for the rate at which your monitor updates. One cycle per sec is equivalent to one Hertz. Your display is refreshing 100 times per second if it is set to update at a rate of 100 Hertz. The Gigahertz used to measure CPU performance is same as the Hertz used to measure the monitor refresh rates is, however, Gigahertz is measured in billions of cycles per second. 

Because there aren’t enough updates per second, your LCD monitor may appear to be blinking if the refresh rate is set too low. While the refresh rate of roughly 30 Hertz is acceptable, others notice the blinking and demand a greater rate. 

Causes Of Samsung Screen Blinking: 

If your screen continues to flicker even after adjusting the refresh rate, it may be due to other issues. Here’s a list of other things to look into:

  • Input port: If feasible, use a different input connection on the monitor as an alternative. If you’re connecting via HDMI, for example, try DVI, DisplayPort, or VGA instead to see if it solves the problem.
  • Video card: If your video card is malfunctioning, the output on the screen will suffer as a result and it would lead to blinking. To confirm that the video card is correctly inserted in the slot, update the drivers, and open your computer.
  • Cable: Change the cable that connects your CPU and monitor from the energy source if possible. A faulty cable might cause a signal to break while being transferred across the wire in some instances. Most of the times, a cable might cause current and pass it on to the monitor which in return causes the monitor screen to dysfunction and blink. It affects the productivity of your computer and deteriorates its performance. 
  • Monitor: There’s also a possibility that the monitor is broken or malfunctioning. If the problem persists, try connecting the monitor to a different computer. If the screen has some kind of issue, you need to get it checked as soon as possible because if the monitor screen is blinking due to some virus or current, it could affect the whole systema and if it spreads, it can slowly and gradually damage the whole system. 
  • Surroundings: Electromagnetic fields in addition to hardware concerns, can cause screen blinking. Remove anything else connected into the same power strip, such as a heater, fan, or other appliance.

More Reasons for Samsung Monitor Blinking Power Light: 

  • Offline Modes: Many modern monitors use LED blink codes to indicate that they have been powered up and are ready to use but are still in standby mode. In some cases, the monitor’s LED may blink, become yellow, or change color to something other than green, or both. 

You may observe the display’s LED blink regularly until you start up the system when you plug your monitor’s power cord into a switched outlet on your CPU such that turning on the computer powers up the monitor. 

Similarly, if you put your computer in low-power sleep mode, the monitor LED may blink to indicate energy-saving mode until you hit the power button to shut down the monitor properly.

  • Backlight: The parts that form a flat-panel screen’s display panel are illuminated by a light source hidden behind the screen. If this source of light fails or burns out, the monitor will not function properly and will display an error code in the form of blinking LED signal lights. 

Obtaining the appropriate materials and conducting the repair may fall outside the scope of what you can or should do yourself unless you are a certified service technician or own a service business.

  • Video Settings: To support an even greater range of display devices, computer operating systems cover a wide variety of resolutions and visual modes. Not all of these resolutions are compatible with all monitors.

Your screen may black out or refuse to start up if you specify a system preference that your display does not support. You may see onscreen warning messages in addition to the LED blinks that indicate these issues. 

  • Circuitry & Power: Capacitors are commonly found in the power sources of electrical and electronic devices, and they store and release electrical charges briefly. They resemble little plastic-wrapped cylinders or barrels mounted to circuit boards. Capacitors that have swelled and deteriorated over time are no longer able to execute their functions properly. 

Any loss of power or degradation of the monitor’s power source can prevent it from turning on, resulting in an error code shown in LED blinks. Although a skilled technician can replace faulty capacitors, if you don’t know what you’re doing, neither dismantling a device to seek for them nor attempting to repair them is a good idea because they can retain dangerous voltage levels.

Set A Refresh Rate for Higher Performance: 

The refresh rates that your LCD monitor can support are mostly governed by the monitor’s capabilities. While some LCD displays may support a variety of refresh rates, others are limited to only one or two. 

Start by going to Start then Control Panel then Appearance and Personalization then Display to select a new refresh rate for your LCD monitor in Windows. If you’re using Windows 8 or 10, simply right-click the Start button and select Control Panel from the menu. You can go straight to Display if you’re in icon view. On the left, select display settings, and then select on advanced settings in the window on the right at the bottom. 

When you go to the Monitor tab, you’ll notice a few things. First, look for the option of screen refresh rate. This is your LCD monitor’s current refresh rate. When you select the refresh rate from the drop-down box, Windows will show you all of the options available for your monitor.

Because your monitor is most likely limited to one or two refresh rates, this list may be short. Monitors with a refresh rate of 30 to 200 Hertz are available from several manufacturers. Monitors with greater refresh rates are usually more expensive. 144 Hertz is a typical refresh rate for gaming displays.

If a monitor’s price seems too low to you, it’s most likely because it has a low refresh rate. Some new 4K displays, for example, are inexpensive yet only have a 30 Hertz refresh rate, which can make everything on the screen look choppy. There are high chances of screen blinking and flickering if your monitors refresh rate is lower, you can invest money into a computer just to have a smooth experience of working. 

Officers and corporate jobs require heavy workload and if your monitor starts flickering out of nowhere in the middle of a serious meeting, you’re doomed. To make sure you have a good system, your PC need to have a high refresh rate that can take you through heavy working and continuous work without bothering with anything such as flickering or power shot. 


Flickering is one of the most common issues with Samsung monitors. Flickering, lines, and discoloration on the monitor screen could indicate a problem with the power supply or the monitor. The best line of action is to unplug both the computer and the power supply. Unplug everything and let the monitor cool for a minute before plugging it back in.
