It can be one of the most disturbing things to find out if you’re working on your computer and your office monitor suddenly goes black. So, those are some of the topics we’ll be discussing right now.
Although resolving this issue can be simple in certain circumstances, it can also be complicated in others. However, the first step to resolving this issue is identifying the fundamental problem.
While the power light is on, your Monitor goes black at random. You’re not the only one who feels this way! A large number of people is reporting an identical problem. The good news is that it is fixable.
Your Monitor flashes dark at random intervals before returning to normal after a second. It can happen once or multiple times per day, and the worst thing is that there are no error codes to help you figure out what’s causing it or how to fix it.
Some people claim to see the mouse cursor, while others claim to have a completely dark screen. In this article we will solve your query of why does my monitor go black for a second your monitor.
Monitor keeps going Black for a Second:
The problem with the cords connecting your display to your computer is the main cause of its going dark for a few seconds. If your Monitor goes black for a few seconds and then comes back on, this is most likely the problem.
The first step is to properly check that all of your cords are properly positioned in the back of your display and the device to which it is connected (laptop or computer, for example). Make sure that the ports on the back of your Monitor aren’t damaged, as this is a common source of black screens.
It would be great if you also get to know your plug socket and Monitor’s plug since any damage to these could be the source of your problem. In an ideal scenario, after you’ve checked the cords for any damage, you’ll also check the display with a different cable. Assuming you have another HDMI cord (if that’s what you’re using), you’ll want to double-check with your devices as well.
If your display has any alternative ports available, it’s worth experimenting with. It could just be a problem with your Monitor’s ports, and if you insert your cable into a different connecting port, it might work. However, if your screen goes dark, these aren’t the only things you should look at. Something else could be causing the problem.
Reasons on Monitor going Black for Few Seconds:
There are certain reasons for your Monitor going black. These reasons are explained in detail below.
- Graphics Card Drivers:
Another possibility is a problem with your video card drivers. If you suspect that your gadget is having problems, the best thing you can do is update it. This article will show you how to upgrade your graphics drivers quickly and efficiently.
If you’re running Windows 10, make sure your display driver is updated. This may be done by going into your device manager and searching for it.
Although it’s improbable, it’s possible that your GPU has reached the end of its life cycle and is about to die. This will not be the case on a new device, but it is still possible if you have an exceptionally old laptop or computer linked to the Monitor. If this is the issue, your graphics card may need to be replaced.

- Overheated Duration:
Although the cords are the most common cause of display problems, the next most likely scenario I’ve discovered is that you have a problem with the Monitor itself. It could also be caused by overheated components in your laptop or computer, although diagnosing this is tricky.
An overheating monitor can be caused by several factors, the most common of which is a lack of airflow for the internal components. This could be due to dust build-up or a blockage that prevents air from flowing through the Monitor.
So, before you restart the display, ensure that it has been well cleaned. It should normally work after cooling down and restarting your computer after a few hours.
- Energy Saver Issues:
Another way to check is whether or not your computer or laptop has energy saver mode or night mode set. Although this should not cause any issues, there have been reports of the energy saver failing to operate with the Monitor, causing it to black out sporadically.
- Installing a New Software:
If you’ve recently installed software on your device and this problem has arisen, try deleting it as well. There have also been instances where poor software has caused a monitor to blackout. If you’ve recently installed something new on your computer, this will be the cause.
Tips to Avoid your Monitor Going Black:
You should consider a few tips to avoid your Monitor going black. These tips are explained below.
- Reset The Monitor:
A factory reset option is available on several displays. You’ll need to enter your Monitor’s on-screen display (OSD) menu to reset it.
Then, on that menu, look for a factory reset option. If you can’t find one, consult your Monitor’s handbook for more information on resetting your VDU.
By pressing the Windows and S keys simultaneously, you can access the search function.
In the text field of the search tool, type the words “Control Panel.”
Then click Control Panel to open the Control Panel window.
Click the “View by” menu item and choose “Category” from the drop-down menu.
Then, in the Control Panel, go to Hardware and Sound.
To access the options, go to Power Options.
Choose between the high-performance and balanced modes. It makes no difference, but the Power Saver option must be disabled.
Then, for your desired plan, click Change plan settings.
In the Turn off the display drop-down menu, choose Never.
In the “Put the computer to sleep” drop-down menu, select Never.
Save your changes by pressing the Save button.
Test Your Monitor:
Before moving on to more advanced troubleshooting approaches, it’s a good idea to test your display with another tower or borrow a friend’s Monitor to test your case.
This allows you to eliminate some of our options and get to the answer faster.
Also, see whether your monitor functions disappear by lowering the display brightness.
Your Monitor may be too old, inexpensive, or inefficient to work for lengthy periods at full capability.
When you put too much stress on it, it becomes overloaded.
Dimming the brightness is an effective technique to solve this problem.

Check The Cables:
Video and audio signals are sent using video display controllers such as HDMI, VGA, DVI, etc.
Your screen will go black if these signals cannot reach the Monitor.
This could be due to the usage of a splitter, a cable that is too thin or long, or just a low-cost cable.
Increase the cable’s AWG size and make sure it’s no longer than seven feet to rule out those possibilities.
Then, remove any adapters, receivers, or splitters from the circuit and verify whether the issue still exists.
Check All Your Connections:
The black screen problem is due to a faulty connection if you’re lucky.
First, turn off the computer, remove the cords, and inspect them.
Look for visible cuts, bends, corrosion, and other evidence of deterioration on the cords.
If there’s no obvious problem, pinch the cable for a long time to see if the internal circuit is short.
Make sure the plastic jacket is securely fastened and not exposed.
After that, inspect the ports at the back of the tower for deformation or tottering.
You can also try a replacement cable or your existing card with a different device or port to see if anything happens.
If that doesn’t work, try using a different type of cable.
Hopefully, you were able to find an easy solution to your Monitor’s blackout problem. The most common cause is a problem with the device’s wires, but this isn’t always the case, and the problem could be more serious.
It could be an issue with any wires, but it could also be a problem with your power source or the power button on your display. If this is the situation, you’ll need to get it repaired before you can use your display again.
If you have a second monitor, it’s a good idea to examine the same device on it as well. Setting up a different external display will allow you to diagnose the issue quickly.
