Samsung Monitor Keeps Turning OFF [This Should Work!]

I have been using a Samsung monitor for a few months and it was working fine until yesterday. When I turn on my computer, my monitor turns off immediately. 

It was really frustrating for me since this is supposed to be an advanced monitor with lots of features, however, it couldn’t even stay turned on for more than five minutes! 

I have successfully fixed my monitor after hours of struggle. 

So, in this article, I’ll share what I’ve learned so far about why my Samsung Monitor keeps turning off and how you can fix this problem too.

Why Does My Samsung Monitor Keep Turning Off?

Samsung monitors are known for their reliability and durability, but they might suffer from a power issue that results in unexpected shutdowns. 

Faulty power cables or adapters may cause this to the damaged internal wiring, outdated drivers, incompatible graphic cards, or even defective monitors. 

Before you attempt any repairs on your Samsung monitor, if it keeps shutting down constantly, it is important to diagnose the root of the problem first.

How to Fix the Samsung Monitor That Keeps Turning Off?

Samsung Monitor Keeps Turning OFF

Start with the basics by checking the power cable and adapter. Ensure both are in good condition and firmly plugged into the wall socket and Samsung monitor. 

If there is no power connection problem, check if you have installed the correct driver for your Samsung monitor. 

Installing an outdated or incompatible driver could lead to graphical glitches or instability, resulting in unexpected shutdowns.

If the problem persists even after updating your Samsung monitor drivers, inspecting your graphics card might be time. 

An incompatible graphics card can prevent your Samsung monitor from powering on correctly, so make sure it’s compatible with your Samsung display before installing it on your system. 

1- Power Cycle Your Samsung Monitor

To solve a problem that may be causing your monitor to turn off, power cycling your Samsung is the best way. 

That involves unplugging the power cable from the back of the monitor, waiting for at least 30 seconds, and then plugging it back in again. 

This will reset internal circuitry and refresh any settings that might have been changed, which often helps eliminate issues. 

Additionally, you must check all cable connections and ensure they are firmly in place. 

Unplugging and replugging cables also reset any configurations or settings that could lead to power delivery problems. 

Moreover, you should ensure that your Samsung monitor receives enough power from its source by checking the voltage rating on its power adapter and comparing it to what is listed on the Samsung website. 

If everything looks correct, but you’re still having trouble, try replacing your Samsung monitor’s power cord with a new one if possible. 

2- Check the Power Cable

If you still see that your Samsung screen keeps turning off, one of the next things you should look into is the power cable. 

Make sure that both sides are firmly plugged in and that there is no sign of damage to either end of the wire. 

You can also check the outlet by plugging another device in to confirm its capability of providing sufficient electricity. 

If there are any power cord or outlet issues, replace or repair them accordingly. Also, make sure that the sleep mode on your monitor is disabled and the brightness is adjusted correctly. 

3- Check HDMI Cable

Another step in troubleshooting a Samsung monitor is to check the HDMI cable. 

This cable carries the signal from the computer to the monitor, and if it is not functioning properly, it can cause the monitor to turn off. 

To check if this is the issue, try disconnecting and reconnecting both ends of the HDMI cable. Make sure the connection is secure, and there are no bent pins.

If the HDMI cable does not seem to be the issue, then it’s possible that a driver or setting within Windows could be causing the problem. 

To rule out this possibility, try updating the video drivers for your monitor by visiting Samsung’s website.

4- Issue With The Power Supply

The power supply is liable for delivering the essential electrical energy the Samsung screen needs to run its internal components, such as the backlight, control circuits, and display panel. 

However, if the power supply is damaged, it may lead to issues with the monitor’s functionality, including intermittent loss of power and shutdowns.

This could happen since the power supply may not be able to provide consistent and steady electrical current to the monitor for it to function properly. 

Therefore, voltage drops, spikes, or surges may lead to the shutdown or turn off of the monitor completely.

5- Update Samsung Monitor Driver

Updating your Samsung monitor driver is important in ensuring that the device runs smoothly and functions properly. 

The driver is essentially software that helps your computer communicate with the hardware components. 

If you’re having trouble with your monitor turning off unexpectedly, it’s likely due to an outdated or corrupted driver. 

It’s important to keep your drivers up-to-date to ensure the best performance and avoid any potential issues. 

To update your Samsung monitor driver, first, ensure you have the latest driver version installed on your computer. 

You can find this information by going into your computer’s device manager. Once you have the correct version, download and install it onto your computer.

If you’re still having trouble turning off your Samsung monitor, try unplugging it from the power source for a few minutes to reset any stored settings. 

6- Change Graphics Card

If your Samsung monitor is consistently turning off, it also may be due to an outdated or incompatible graphics card. 

Finding the right graphics card model that fits your display can be difficult, but it is essential for optimal performance. 

To change the graphics card in your Samsung monitor, you’ll need to remove the old one and install the new one. 

Before attempting this process, check the manufacturer’s website for compatibility and installation instructions. 

After you’ve installed a compatible graphics card, your Samsung monitor should remain powered on. 

If it continues to shut off, contact an experienced technician for help. They’ll be able to quickly diagnose the problem and make any necessary repairs or replacements. 


If your Samsung monitor keeps turning off randomly, you should try these troubleshooting steps. 

  1. Power Cycle Your Samsung Monitor
  2. Check Power Cable
  3. Check HDMI Cable
  4. Check Power Supply
  5. Update Samsung Monitor Driver
  6. Change Graphics Card

If nothing seems to work, then you should contact the Samsung support team. Because they can help you to figure out what exactly is the problem with your monitor.

However, if they also fail to fix your monitor. Then you should return it, if it is under warranty, and buy a new one.
