Display detected but no picture

Display detected but no picture DEFAULT

Hello , sorry about your problems. My name is Marco and I am independent advisor. So, I will do my best to help you.

It may come from a problem with the video card. As you have already updated the drivers, you can simply uninstall the video card drivers, restart the computer with the 2 screens connected and reinstall the card drivers.

Have you tried the screen on another computer but have you tried it on the same PC but alone without the other screen?

You can also try to update Windows if you haven't already.

Ok but in your image, the other screen still seems to be connected to the same computer. You must connect the screen alone, without the second monitor.

Both screens work fine

The one on the right is the main ( all -in-one) 

the one on the left is the second screen (it's working fine by itself, I have tried it on another computer)

but when I connected them as a dual monitor, the one on the left works fine when I start the computer, both monitors will show HP logo fine

but when windows starts, the one on the left go to sleep and show HDMI: Inactive 

Does that make sense?

Screen mirroring has become an important concept for every person when it comes to utilizing your work. When you are getting connected with different devices, having a decent feature that allows you to get complete access to a second monitor and you can enjoy gaming to a next level.

2nd Monitor Detected But Not Displaying

Of course, if you have two monitors in your home and are unable to set them up, it comes with disappointment. If you are having two monitors on display and not being able to use them at all, you won’t have to get disappointed. This guide on troubleshooting the 2nd Monitor Detected But Not Displaying problem will help you to get a complete result.

How Do I Resolve 2nd Monitor Detected But Not Displaying Issue?

Most of the people face this problem as a common factor when they configure two monitors but they are not in any display even after getting detected. If you are using or working with multiple applications or willing to do a split-screen work, opting for two monitors becomes handy. Because of this, you will be able to play your favourite games, make use of the multiple works with different screens at the same time.

However, the problem is when you face a technical fault with the monitor that you use. Finding out a solution to fix up this issue is a major thing that you need to consider. Sometimes, the procedures for diagnosing these problems are different for the different OS.

First Steps to Take

Monitor problems are open. The biggest problem that you need to consider is to set up the monitor. You may do a lot of work including programming or even designing the application. You may face such a situation when you are playing your favourite game and suddenly the monitor blacks out.

Before you opt to go for technical diagnosis, you need to ensure that the monitor is working perfectly and there are no technical faults present at all. Below are some of the things that you can always consider.

1. First Time?

When you find this fault for the first time, you need to figure about if this is the first time you are facing this issue or not. If this is not the first time you are facing this issue, you must know if the fault is repeated over a number of other monitors or this is the first time.

You must know if there is a similar problem with other monitors as well. If the problem is repetitive over other monitors, there must be an issue with the cables or the connector that you are using. There might be some problem with the graphics card as well. You can either repeat the procedure you have used to fix the work.

2. Check the CPU

Sometimes, it might be just a slight problem with the cpu and there is a huge blow to the monitor. The cpu might detect another monitor but it is usable to transmit the data. Sometimes, the old school methods work the best to figure out a solution.

Go to the settings page of your PC and you will be able to find the start menu. Simply switch off the system and keep it turned off for a few minutes. You can also restart your computer after a few minutes.

3. An Alternative Configuration

Sometimes, it may just be because of the configuration settings as well as the cable settings. It is always better if you could change these settings and then you can bring up the new configuration options available.

If you have an extra monitor in your hand, you can always check out the status of this and figure out what to do with it. Using a working cable will be the best option to get the results. You can quickly figure out where the problem lies with this configuration.

4. Check the drivers

Another important thing that you need to consider is by checking the drivers. Sometimes, these drivers may not be updated and as a result, the system will crash. This may result in easy testing and also figuring out what the real problem is.

It is evident that you cannot use the older monitor for multiple requirements. It has to be updated with proper drivers and then it will match up with the specifications.

5. Viruses

Viruses inside the PC could always be a primary reason why you’re facing such problems. It is important for you to clean up the PC at regular intervals. Make sure that you are having an updated driver and a software that will help you to get the best results right away.

Steps to Fix Second Monitor Detected but not Displaying Problem

Step 1

The first thing that you need to do is to go to the settings page available on your PC. You will have to check the default settings for the display. If it is not on the dual monitor display mode, the things will not go well. You need to make sure that the monitor is in the desired configurations.

Step 2

If there is a massive fault in the hardware, the chances for fix are slim. If the monitor is broken, you will have to replace it. However, you can also check the condition of the cables as well as the connector. Make sure that the cables are intact and working properly. You can also take a spare monitor to test the quality.

Step 3

If it is working fine, the next step is to go to the driver. Sometimes, when the monitor is old, the drivers installed with it are also outdated. Make sure that you have updated the drivers and have used the new configuration files. If you have the same version to update, remove it and then reinstall the file.

Step 4

System restore is one such thing that will help you to bring back the pc to the original point. However, to get this restore done, you will have to make sure that you create new restore points in your PC. It is important to have multiple restore points set up in your PC.

Step 5

If none of the options do work for you, the only thing left will be to install the OS again. You can expect that the system will crash and you will have to reinstall the OS again. This will help you to get easy access to the PC and bring up fast configurations.

That's a bit strange. :(You'll need to run some series of test to see which one really is faulty.
- Start with the Dell monitor, to prove the functionality of the monitor do test it with a different PC or laptop as well and see if it will work or not since your laptop does work fine using a different display or TV.
- If the Dell monitor will work with a different laptop do a clean install of the graphics card driver.
- Go to Device Manager and uninstall the Nvidia driver.
- Check Programs and Features as well and uninstall anything related to Nvidia.
- Once done, download and install the latest driver from the manufacturers site.

Windows 10 Not Detecting Second Monitor -- Solution For Connecting Second Monitor In Windows 10
2nd screen not working

A second monitor that's not detected by your computer can be very disappointing. You won't be able to use your second monitor and multitask, and of course, a faulty monitor can be due to broken graphics cards or a problem with your computer.

Take an unresponsive monitor as a sign of a worse problem and act fast. And there's hope for a 2nd monitor detected but not displaying, let's figure out how to deal with this problem and get your second monitor up and running. 

2nd Monitor Detected But Not Displaying - How to Resolve This Issue 

One of the most common problems when working with multiple monitor setups is a 2nd monitor detected but not displaying. Using a second monitor or multiple monitors is one of the most convenient ways to work with multiple applications. You can play games, edit videos, and work on different screens at a time. But the problem starts when one of your monitors start to falter. So how do you fix a second monitor not displaying issue or when your computer turns on but no signal to monitor is detected? If you're on Windows 10, how do you deal with a second monitor not displaying Windows 10? Here are some handy tips for you.

The First Steps 

Usually, monitor problems happen the least you expect it. You might be in the middle of work, programming, or designing an app when the monitor you're working from shuts down. You might be completely engrossed in a game when suddenly, your monitor dies, leaving you stunned and worried. Still, another scenario is when you just can't power on your second monitor, and you desperately need to get to work.  

So before panicking, assess the situation and perform a basic check. You may also check our monitors reviews to get to know the best computer monitors in the market today.

monitor not working

1. Is This the First Use? 

Have you had the same issue before? Is this a recurring issue with the particular monitor, or have you experienced this in your other monitors? Also, has this happened with other people as well?

If this is the first time that it happened, then it could be an issue with the monitor, the cables, or connectors, or it may be problems with the graphics card. If this has happened before, then review the steps you have used to fix your monitor in the past. Perform these troubleshooting steps and see if it works. If the problem persists, then there may be a problem with the monitor, cable, or system.

If this is a recurring problem in your office or company, consider calling tech support to assist you. If this happens mostly at home, then consult an IT or a computer expert to check your system and possibly your home's electrical wiring.

2. Restart Your Computer 

Most problems concerning an old PC or laptop may be resolved by restarting your PC. With one working monitor, close all open programs, applications, and documents. Sign out of your profile and do a restart. Sometimes an old computer has to update first so don't hurry. Wait for the updates to finish before you log in.  

For an update, do not power off your laptop or PC. Also, your internet connection should be stable (don't let anyone turn off the modem). Once the update is installed, your system will allow you to log in. Once you're in, check if your system recognizes the second monitor.

3. Test With An Alternative Configuration 

If your computer still does not recognize the second monitor, use a different configuration. Use a different monitor cable and check.  Sometimes, there may be problems with the pins found at the cable connector, or this may be a problem regarding a bad cable (old, worn out, or pest-bitten cable). If this does not work, try another monitor. 

If you have an extra monitor in your office or home office, connect this to your system using a working monitor cable. If there are multiple ports at the back of the monitor (VGA, HDMI, or component cables), you may try any of these ports and check which one works.  

4. Are the Graphics/Monitor Drivers Updated? 

Old PCs and systems may have outdated graphics or monitor drivers. Sometimes, updated the graphics and drivers may help your system recognize the second monitor. Usually, an older monitor starts to falter before the newer ones. When this happens, it may be a sign that your graphics card is acting up. 

If you are certain that the graphics and monitor drivers are your problem, then ask a professional to help you out. Have your system checked right away. 

5. Checked for Any Viruses 

There are times when a second monitor is detected but not display; this could be due to a recent virus attack. A CNET poll discusses the possible threats of computer viruses that target the PC monitor. There is a possibility that there are viruses out there that can affect your computer monitor. The best way to deal with this issue is to do a quick scan or a system scan. A system scan takes longer but is convenient and will check for all other issues. You can schedule regular PC checks and system scans from your system.  

7 Steps to Fix 2nd Monitor Detected But Not Displaying Problem

A second monitor may not be a requirement to use a PC, but it is a great idea if you want to multitask. With two monitors, you don't need to press Alt+Tab to move from one program to another. You will have a full screen dedicated to your primary application, while the extra screen can be used for just about anything. And when the second monitor is having issues, remember the following simple steps.

Step 1: Change the Dual Monitor's Display Settings 

In cases when your Windows 10 PC is unresponsive and still cannot detect a second monitor, you may need to force the second monitor or display to appear using second display detection. This is done from the Settings tab of your system.

Open Settings and then click System. Click Display and move to the section that says, "Rearrange your displays." Click the button that says "Detect" which is commonly found in the bottom right-hand corner.

After doing these, your Windows 10 system should be able to detect your second screen. When it has detected it, you can set it up from the Display on the Settings tab.

Step 2: Check and Test the Hardware 

If manually encouraging your system to detect your second monitor still does not do it, remove the ailing monitor, and test it. If you have another PC, attach the monitor and check if it works, use the same cable you used to install it on your PC. If the monitor doesn't work, use another cable. If this does not work still, consider using a new power cord. Test the hardware in another PC and do the same thing.

If the monitor works or if it's detected by the PC, install it as a secondary monitor. If the monitor works, then you can isolate the problem, which may be due to an ailing or outdated graphics driver. 

And if the problematic second monitor is connected wirelessly to your PC, try to reboot your Bluetooth or connect the monitor using cables instead of using a wireless connection.

Step 3: Reinstall or Update Graphics Driver 

From Windows 10, a corrupted part or an outdated version of your graphics driver may cause the system to overlook a second monitor. To correct this, you must update the graphics driver. If you already have the latest graphics driver version, reinstalling this may help. If all else fails, downgrade to a much older version so you can fix the connection of your computer with an older monitor.  

From the Device Manager, choose the top result to start the app. Expand by double-clicking the Display Adapters. From here, right-click and select the Update Driver. A dialog box will open and will ask you, "How do you want to search for drivers?" choose Search automatically for updated driver software.

Step 4: Update Graphics Driver With Manufacturer Control Panel 

You can update a graphics driver from the manufacturer's control panel as well. Graphics driver brands like Intel (Intel Driver & Support Assistant), NVIDIA (INVIDIA GeForce Experience), and AMD (AMD Radeon Software Adrenalin Edition). Choose the brand of y our graphics driver and simply follow the instructions as you go.

If you're unsure about the brand of your graphics card, click System Information from the Start menu. Click the top result and double click to expand Components found at the left pane. Choose the Display category, and afterward, you may now readily see the Adapter Type and the Driver Version. 

Step 5: Perform System Restore 

Open Start and search for "Create a restore point" and choose the top result. Open System Properties and click System Restore. Click the Next and choose the restore point which you want to use. Clicking System Restore will change your PC settings according to its last known good configuration of your system. 

But before you use Restore Point, you must first enable it so Windows 10 will create your system's restore points. You can enable it from the Create a restore point in the System Restore feature of your computer. Also, this is only accessible from system drives or the computer with an installed OS. 

Step 6: Update your Windows/Mac Operating System 

You may also update Windows or your Mac system to force the second monitor to work. In Windows 10, you can choose when or how to get updates. To check for any updates right away, go to Settings, move to Update & Security, and Windows Update. 

From this section, click the search for updates. Your system will begin to check for any updates—schedule updates from this page as well. With scheduled updates, your system will notify you if you need to restart to update. 

Step 7: Scan Computer For Viruses After Update 

Right after the update, use Windows Security from the Start menu to launch the scan. Click the "Virus & threat protection" and then click on "Quick scan." This scan may take a while, so don't power off your computer. Just wait for this to complete before doing anything. 

Scanning your computer for viruses may be done automatically as well. Schedule a scan using the Windows Defender Antivirus, look for Schedule tasks. From the left side, expand the Task Scheduler Library, Microsoft, Windows finally, scroll down to choose Windows Defender. From the top, double-click the Windows Defender Scheduled Scan to schedule an automatic scan.

Step 8: If Nothing Helps, Reinstall your Windows/Mac Operating System 

If the second monitor is not displaying a problem persists, despite testing the hardware, updating drivers, and using System Restore and performing Windows 10 updates, you may need to reinstall your operating system. This is the last resort if all else fails, so try everything first. 

Reinstalling Windows 10 will solve most of the problems you have with your computer. This will also help you create a fresh Windows 10 copy, which is minus all the old files and apps. Before you start, check your disk space and free some space. See if this helps first before you reinstall Windows 10 or your Mac OS.

But display no picture detected

No display or black screen on a computer monitor

Updated: 07/06/2021 by Computer Hope

Computer monitor with a blank screen.

If your computer monitor displays a black screen and no picture when you turn on your computer, the following steps may help you troubleshoot or repair the problem.

Monitor is not on

It may seem obvious, but first, make sure the monitor is turned on. If you don't see a power LED (blue, green, or orange light) on the monitor's front or bottom, press the power button again. If no light comes on after several attempts, proceed to the next section.

Computer is asleep

If you stepped away from the computer for a bit and returned to a black screen, the computer is likely asleep. Try moving your mouse, clicking the mouse buttons, or pressing any key (e.g., spacebar) to wake it up. If none of those actions work, press the power button.

Loose or improper connections

Another reason for a black screen is, the computer isn't communicating with the monitor properly from loose or improper cable connections. The following steps help you ensure the monitor is connected correctly to the computer.

HDMI cable

Check the data cable

Ensure the monitor's data transfer cable is connected correctly to the computer. It should be inserted completely and firmly in place. Older monitors use a VGA cable, but most new displays utilize a DVI or HDMI cable and port.


Make sure the cable is connecting to the correct video port. Most new video cards have multiple connections and your motherboard may also have its own connection.

Check the power cable

Next, verify the monitor has power by looking for a blue, green, or orange light. This light is found on the front or the bottom of the monitor's bezel.

If you see no lights on the monitor, make sure it is connected to a working wall outlet. If the power cord is removable from the back of the monitor, try replacing it with another power cable. If you still cannot turn on the monitor after trying another wall outlet and cable, the monitor is broken and should be replaced.

Check the LED status

If the monitor status light is orange or flashing, verify the monitor is not in Standby mode, by moving the mouse or pressing the . If this doesn't help, reconnect the data cable to the computer and back of the monitor, and then restart your computer.

Try a different cable

If your monitor is getting power, but no image appears, the data cable may be the issue. Try using a different DVI, HDMI, or DisplayPort cable with your monitor.

Turn up the brightness and contrast

If you're able to view your monitor's settings menu even though the screen is blank, you likely need to turn up the brightness and contrast.


If the computer doesn't pass POST, it won't turn on, and your monitor remains black. If you hear beeping when you turn on your computer, run through the POST troubleshooting steps to determine the issue.

Hardware issue

If you have followed the recommendations above and still no picture appears, your computer may have either a bad monitor, video card (graphics card), or motherboard. The best method of determining this is to try the suggestions below.

Borrow someone else's computer monitor and connect it to your computer

If another monitor works on your computer, it's safe to assume the non-working monitor is bad and should be replaced. While it may be possible to have the monitor serviced, it is often cheaper and easier to purchase a new one.

Disconnect your monitor and connect it to another computer

If your monitor works on another computer, the video card is bad. Try removing video card from the affected computer and installing it in another computer. If it does not work in the other computer, the video card is most likely bad and needs to be replaced.

If your monitor and video card work with another computer, your motherboard probably has an issue. You can attempt to troubleshoot motherboard problems using the link below. If you determine the motherboard is bad, or you cannot successfully run any tests, we suggest replacing the motherboard to fix the display problem.

FIX: Windows 10 Not Detecting Second Monitor [Quick Tutorial]

Troubleshooting Steps: How to Fix 2nd Monitor Detected but Not Displaying

Given that you have gone through the preliminary steps above, let us now talk about how to fix 2nd monitor detected but not displaying issue in detail.

Step 1: Change The Dual Monitor’s Display Settings

Assuming You are on Windows 10:

Solution 1: Try Detecting The Monitor AGAIN

  1. 1

    From your first monitor, right click on empty area within the desktop and choose “Display Settings”.
  2. 2

    Under the Multple Display heading, press “Detect”. The windows will then attempt to detect the monitor.

Solution 2: Device Manager

  1. 1

    Press Windows Key + X, this will open a a quick short cut bar.
  2. 2

    Select Device Manager
  3. 3

    The two tabs of concern to you are “Display Adapters” and “Monitors”. Here you need to make sure that,
  • Your graphics card is being detected by the OS, this is especially important if you are using a dedicated graphic card. NOTE: NOT ALL COMPUTERS HAVE A DEDICATED GRAPHICS CARD. MOST HAVE INTEGRATED GRAPHICS CARD i.e INTEL HD GRAPHICS 630.
  • Check for any errors with yellow caution sign. This means that something is wrong with the drivers.
Device Manager

Step 2: Check And Test The Hardware

Here are few things to consider here.

  1. 1

    Have you tried using your second monitor as the primary monitor? does it work when it is the only monitor connected? If so, the problem lies either with Windows settings, or with the hardware, this could be as simple as an issue with a video Port.
  2. 2

    Have you tried replacing the second monitor with a different one? If a new second monitor works well when connected to the computer, then the old one may be faulty. You need to service the second monitor or replace with a different one. If the new second monitor does not display but is detected just like the old one, then the problem may be within the computer.
  3. 3

    If you have another PC lying around, try connecting both of your displays to it and see if they both work. It’ll be worth calling in a friend with a laptop/PC to help you out if you don’t have a spare system lying around. This is just to make sure whether the issue lies with the monitor or the computer.
  4. 4

    Have your tried changing the cables?
  5. 5

    Have your tried using a different Video Out port from your computer?

Step 3: Reinstall Or Update Graphics Driver

Assuming that you have checked your hardware and you are certain that the second display has no hardware defect and that it works fine when connected as the primary display, then the software could be the culprit.

A graphics driver is responsible for enabling the operating systems and software programs on your computer to use the graphics hardware. For better performance of the computer, the graphics drivers should be updated.

Graphics driver is not only used for gaming purposes but also in projectors and external displays. To update a graphics driver on Windows 10:

Solution 1: Check for Updates Via Device Manager

  1. 1

    Press Windows Key + X, this will open a a quick short cut bar.
  2. 2

    Select Device Manager
  3. 3

    Click “Display Adapters”
  4. 4

    Right click on the graphics card and choose Update Driver. You may need to do this for both integrated and dedicated graphics card if you have a dedicated graphics card installed.

Solution 2: Check For Updates on Official Websites

  1. 1

    If you have a dedicated graphics card like AMD or NVIDIA, then visit their website to download the latest drivers
  2. 2

    Restart the computer after you install new drivers.

Solution 3: Check for Windows Updates

Update your operating system. To Check for Updates, you need to open Windows Update and let it search for updates while connected to the internet. On Windows 10 it is quite simple

  1. 1

    Go to Windows Search available in lower left corner of the task bar.
  2. 2

    Type “Check for Updates”
  3. 3

    Press the “Check for Updates” option
  4. 4

    A window will open. Let it search and install the updates from here.
Check for Updates

Ensure you are connected to internet and then choose search automatically for updated drivers.

If you are unable to find the drivers, you can then go to the computer manufacturer’s website for further instructions on how to download and install the graphics driver. If this does not work, proceed to the next step.

Step 3: Perform System Restore

If you recently installed a software, device driver or Windows update, the process may have affected your computer from working well.

Therefore, you need to perform system restore to previous state when the computer was displaying the second monitor (if it displayed). There are several recovery options, depending on the problems that you are facing:

  1. 1

    The computer stopped displaying the second monitor once you installed a software application: Choose restore point and restore the system.
  2. 2

    The computer stopped displaying the second monitor once you installed an update: Delete the recent Windows update.
  3. 3

    The computer stopped displaying the second monitor once you installed a driver, software application or update: Reset the computer
  4. 4

    You want to reinstall the Windows operating system: Go to previous version of installed Windows.

Choose one of the options that works well depending on your situation, follow the steps and then let the Windows do the rest. Test the display of second monitor to see if this works and if it doesn’t, try the step below.

Step 4: Update Your Windows Operating System

If your Windows operating system is up to date, ignore this step. Otherwise, follow these steps to update your Windows.

Depending on the OS that you are using, you can find the Windows Update option in control panel, or simply through Windows Search.

Ensure that you are connected to the internet so that the updates can be downloaded. Once the updates are downloaded, install them and restart your computer.

Windows update are important as the help you to protect your system or remove bugs that may affect the system. Besides, the driver updates are downloaded and installed during the process. Since latest drivers are installed, the newly updated graphic drivers may also affect the display of the second monitor. If the Windows update does not help with display, proceed to the step below.

Step 5: Scan Computer For Viruses

This is a long shot, but this can also be the culprit.

Some viruses or malwares can corrupt some system files and thus may be the cause of issues with second monitor not displaying.

If you do not have an antivirus software, you can try to install one and then perform full scan on your system.

If you are using Windows 10, the Windows Defender is a great anti-virus software that is available to you without any cost. Just make sure that it is updated.

Other than that, there are several antivirus software that you can try for free for a limited time.

Step 6: Reinstall Your Windows Operating System


If you are absolutely sure that nothing is physically wrong with your second monitor and that you have tried to configure the settings properly, then this could be your last resort.

I would advise that you seek professional help before wiping out your windows. Also, make sure that you have backed up all your media before performing this step.

To reinstall the Windows, you can either use the installation media (DVD or USB drive) or reset computer from the updates and security option in the control panel.

I would recommend the clean install where you install from the bootable disk or USB drive.

Monitor Detected But Not Displaying

Using a computer with multiple monitor setup is almost every PC owner’s dream. However, it can be highly disappointing to see the second monitor not working, even after getting detected by the computer.

Maybe there is some issue going on with your computer’s graphics card settings. Or, it is just some hardware issue of the monitor itself. Whatever it is, we will be providing you with some simple fixes that can help you get out of this situation easily.

Hence, if you are looking for methods to fix the problem where the monitor is detected but not displaying, stay tuned till the end as we will be going in-depth to find the right fix.

Monitor Detected But Not Displaying – How to Resolve This Issue

Is This the First Use?

Before directly jumping to any conclusions or start finding the fixes, we must find out why this problem is occurring in the first place? Have you experienced similar issues with the same monitor or other monitors ever before? Or is it just happening for the first time with the new monitor?

If that happens frequently with your computer monitors, then it may be due to some software issue or may be related to your graphics card. However, if other monitors are working fine, and the new one isn’t, then it is pretty clear that the monitor has some sort of issue.

Restart Your Computer

No matter what sort of problem occurs with your PC, a casual reboot can significantly fix most of the basic bugs. Generally, PCs with older hardware do sometimes struggle a bit to load and configure new hardware like secondary monitors.

With a fresh restart of the PC, if there is some problem going on with the drivers, it will get fixed. Just make sure the computer is connected to an active internet connection at the time of rebooting.

Test with an Alternative Configuration

If restarting the PC doesn’t help you, there’s another thing you can try out. Since you have got two monitors and one of them is only working, try swapping the connection ports. If the primary monitor works with other ports as well, the 2nd monitor might be faulty.

Otherwise, there must be some issue with the port only. In case your primary monitor works fine with all ports, there are high chances that the 2nd monitor’s wire is faulty. Try testing out the monitor with different configurations, you can use HDMI connections, DisplayPort connection and see what works best.

Are the Graphics/Monitor Drivers Updated?

If you are using a graphics card, either from Nvidia or AMD, keeping the drivers updated is a necessary task. Sometimes, due to the older drivers, several graphics cards may show you problems like this. Hence, make sure all the drivers on your computer are updated properly, and then try reconnecting the monitor to the PC.

Checked for Any Viruses

The chances of facing such kind of problems because of a computer virus is very little. However, if you have checked for all the other possibilities, this is the last one to be worried about. Try running a full system scan with the help of any anti-malware or antivirus software on your PC. Moreover, if there is any pending Windows update, try installing that as well.
