multimonitor display screens flashing factory

Be sure to try the Display driver steps to find the driver which works best to resolve the problem if it returns. Hopefully not, but one of the steps I gave above will usually fix it, so bookmark the thread in case you need to refer back to it.

If your Windows 10 or Windows 11 screen is constantly flickering, it"s likely because you have a troublesome application installed or an unsuitable display driver. It"s time for you to resolve that annoying screen flash.
The problem often begins when upgrading to Windows 10/11 from a previous version of the operating system, but it can occur at any time. We"re going to show you various methods to fix a Windows 10 or Windows 11 flashing screen.
Now, watch your screen to see if Task Manager flickers. If it does, along with everything else on the screen, the problem is likely caused by your hardware or a faulty display driver. On the other hand, if everything except Task Manager flickers, the issue is likely due to an application.
If you have a flashing screen, the first thing to rule out is the hardware. Check all the cable connections from the monitor to the computer—take them out and plug them back in to ensure the cables are secure.
Use the Refresh rate dropdown and incrementally select lower rates until the screen flashing stops. If the flashing continues, revert to your monitor"s recommended refresh rate.
The screen flashing could be caused by your display driver. You might have an old driver or a faulty new one. Let"s make sure you are running the right version for your system.
If the problem isn"t with your display driver, it doesn"t mean your graphics card isn"t to blame. If your graphics card isn"t seated correctly in your motherboard, it can cause your monitor display to flicker on and off.
You can easily check this if your motherboard has inbuilt graphics. Remove the monitor cable from your graphics card and plug it into the motherboard"s display slot instead. If the flashing stops, you know the graphics card is the problem.
Some apps are incompatible with Windows 10/11 and can cause screen flickering. Think about whether you installed any new software before the screen flashing began or if an app recently updated. In the past, three problematic apps have been Norton Antivirus, iCloud, and IDT Audio.
Across all your applications, make sure you"re running the latest versions. Either update within the app itself or head to the respective official websites and download the most up-to-date release. Alternatively, check the developer"s support page for recently updated apps to see if screen flashing is known as a recent bug.
As with most Windows 10/11 issues, no one fix will work for everyone. Hopefully, one of the steps above has solved your Windows 10 or Windows 11 screen flashing problem.

When TechRepublic first published a tutorial to correct flickering monitors, it was 2001. Since then, the computer world has changed significantly, and screens have come a long way. For example, CRT monitors — which were the norm back then — are much more sensitive and temperamental than the modern LED screens many of us use today.
But, despite this and many other advancements in screen technology, flickering screens are still an issue. And because screens have evolved as device types have diversified, the quest for solving this kind of problem has grown more complex.
The first thing you need to check if you are using a monitor that connects to a computer is the cables. Whether you’re using VGA, HDMI, DVI or a display port cable to connect your monitor to a computer, it makes no difference; if the cable isn’t securely connected, there are going to be issues.
Laptop screens have cables that run hidden inside the frame and core of your computer. While you will not be able to rapidly fix this without professional help, you can identify if the cables are the problem.
Note the refresh rates that appear; these will differ, depending on your display and what it supports. Some laptops and external displays will support higher refresh rates than others.
Flickering screens on laptops, smartphones and tablets may be caused by physical damage, like after the user has dropped the device. In hardware damage cases, only professional support can help you identify and solve the problem. Before taking your device to be fixed, you might want to check out a couple more of our tips.
Nearly all devices use a video card to properly display images. In desktop computers, this device needs to be properly positioned on the motherboard or it will cause a lot of problems, which could include a screen flicker. You can check your desktop computer video card by turning your computer off and opening the outer case.
True Tone is designed to automatically correct images based on light levels, but this feature can cause a screen to flicker. To disable True Tone, go to the Apple menu, then System Preferences and click Displays. Now select your display and click on Display Settings. From here you can uncheck the True Tone checkbox (Figure F).
An incompatible driver or app can cause screen flickering problems. Microsoft’s official support page for Troubleshoot screen flickering in Windows has a detailed step-by-step on how to solve driver and app display problems like this.
A flickering screen can be a real nightmare; fortunately, screens are more resilient than they were a couple of years ago. Additionally, there are numerous tricks, tips and steps you can take before even thinking about repairing your screen or replacing it for a new one. Regardless of what kind of screen you’re struggling with, this guide offers great initial resources for solving the problem.

We have had an issue with one of our computers’ second monitor that keeps flickering and flashing randomly. To be precise, it goes black entirely and comes back on again repetitively (as if it goes to sleep and immediately wake up again) while the primary monitor works just fine. After trying all possible solutions, including switching to other monitors, fortunately, the issue is solved.
This guide will show you what we have tried to fix the second monitor keeps flickering and flashing issue. Though the solutions we shared in this post worked for us, we certainly can’t guarantee that it will work for everyone else.
At first we thought it was due to driver issue or loose cable. We tried to update the monitor driver (which is something you should try first regardless if it works), checking and replacing the HDMI cable (or displayport), trying different resolutions, but to no avail. So, we went on to try the settings in the Nvidia Control Panel and found the solution.
In the control panel, expand Display and select Set up multiple displays. Select and enable the displays you want to use. Then, drag the icons (usually appear as 1 and 2 where 1 is your primary monitor and 2 represents your second monitor) to whichever direction you want.
For example, in the screenshot below, my second monitor will be on the left of my primary monitor. Then, click on Apply. The random flickering or flashing should stop now.
It doesn’t matter if you have configured this before in the default Windows settings, the point is to configure this once again in the Nvidia Control Panel and it somehow solved the flashing issue for us.
This is another method you can try to fix the flickering and flashing problem if your monitor is connected using HDMI but not via DisplayPort (you can’t see the option if you use displayport).
In Nvidia Control Panel, under Display, go to Adjust desktop color settings. Select the your primary monitor and at the bottom under the “Content type reported to the display” option, select Desktop programs. At the top, select your second monitor and also change the option to “Desktop programs” as well. Click on Apply. Restart your PC and see if the flashing issue is fixed.
Check the screen refresh rate setting of the second monitor and see if it is set correctly. Right-click on your desktop > Select Display settings > Advanced display settings > Display adapter properties for Display 2 > Monitor tab > Screen refresh rate. If you are using a 60hz monitor, try to change the refresh rate to 60hz if it’s otherwise. Also, try to change it to 59hz and see if it works.
If your monitor offers other types of input port, try using another type of input port. For example, if you are using HDMI right now, try using DisplayPort or DVI if your monitor has the port.
Hopefully this will help you solve your second monitor flickering and flashing issue. If you have other solutions you may want to share with others, let us know in the comment section below.

We’ve found that sometimes those problems are caused by an incompatibility between the DisplayLink drivers and the main graphics cards drivers. In some instances you need to get the latest ones, and in others you need to go one step back. Are you using Lenovo’s drivers or are you using ATI issued drivers?

If you’ve followed our guide on how to set up multiple monitors and you’re running into difficulties like the second monitor not displaying properly, not turning on at all, or your games aren’t displaying on the right monitor, then check out the list below of the most common multi-monitor problems for your desktop PC or laptop and how to fix them in Windows 10 and 11.
Although getting no signal to your new monitor can be cause for concern, it’s arguably the easiest problem to fix. It simply means that the display has power, but it isn’t receiving visual data. There are several reasons why this happens and plenty of fixes you can try to sort it out.
Force Windows to detect your monitor: Maybe Windows didn’t recognize your second display’s connection. To force it to check again, right-click the desktop and select Display Settings from the resulting pop-up menu. In the following window, click the Detect button located under the display diagram. In Windows 11, you can find this under the Multiple Displays section.
Turn the screen off and on: Some connection types don’t like hot swapping while a different monitor is powered on. Turn the display off and then on again. That may be all it needs to recognize the video feed and start displaying it correctly.
Remove other peripheral devices: Disconnect any connected cameras or other unnecessary peripherals. If your display starts working afterward, these connections were probably interfering with your setup. You may need to find newer, compatible accessories or use connections on your PC instead of your monitor.
Verify the correct input: Monitors with multiple input options need you to manually select which cable and port you’re using, like HDMI 1, HDMI 2, DisplayPort 1.4, USB-C, and so on. Use the buttons on your monitor to cycle through the channels and select the correct input from your PC. If you are using an adapter to switch from one type of input to another, this may be causing issues with the other monitor. Try to remove the adapter if possible, or replace it with another adapter to see if this fixes the issue.
Change data cable: If you’re using an older cable standard like VGA or DVI-D, you might want to try a newer alternative like HDMI or DisplayPort. You can also try using a new cable in case the old one has issues (bent pins, a short, exposed wire, etc.).
If you’re still having trouble with your extended desktop monitor, verify that it works by unplugging the primary screen and double-checking the above steps again. If it does, consider running it as the primary display until you determine the root problem. If it doesn’t, contact your retailer or manufacturer to discuss a return or replacement.
If you add a new, higher-resolution monitor to your system and find that it’s not displaying correctly, it might be borrowing settings from an older display, or simply trying to match your primary monitor.
Step 4: Select a screen resolution that works best for you. Windows designates one of these resolutions as “recommended” based on the display’s hardware.
If your monitor is set at an incorrect refresh rate, it will display a “no signal” error. That means the PC is outputting a signal the display simply can’t handle, requiring you to manually adjust the output in Windows.
Step 2:The Settings app opens with the Display panel loaded by default. Scroll down and click the Advanced Display Settings link located under Multiple Displays.
Switch cables: If you have the option, try a different cable standard, like switching from DisplayPort to HDMI or vice-versa. When doing this, make sure the cables you are using support your current resolution — older cables may not support UHD/4K resolutions, which could cause this aspect ratio issue.
Check your display orientation: This isn’t as common, but the issue may be the monitor’s orientation. In Windows, go to the Display section and look for Display Orientation. Try switching the orientation to something like Portrait, then switch it back to Landscape and see if this helps.
It’s not uncommon for games to display on your second monitor rather than your first, which isn’t ideal if you have a primary display for gaming and a secondary for everything else. Fortunately, there are some quick and easy ways to fix it.
Use in-game settings: The easiest way is often to just tell the game to display on your primary monitor. Some games have the option of selecting a display in their settings menu, so check there first before adjusting anything else.
Check your display outputs: If you find that this isn’t the first time a game or application has displayed on the wrong monitor, you might want to check your inputs. Is your secondary display plugged into the primary display output on your graphics card? Try swapping them around to see if that fixes things.
Make it your primary display: Press Windows Key + I to open the Settings menu, then navigate to System > Display. Select the monitor you want your games to appear on, and select the box next to Make this my primary display.
Only use one monitor: If the above doesn’t work, in Display settings, select the display you want to game on. From the Monitor Settings (Windows 11) or Multiple Displays (Windows 10) drop-down, select Show only on 1 or Show only on 2 as appropriate. You will need to turn this back off once you’ve finished gaming, but it is a surefire way to get your game working on the right display.
There are a few different ways to display content on two screens, but Duplicate is often the default. If your second display merely copies the desktop rather than extend it, here’s how to change that view.
Make sure that your settings are on Extend these displays: In theMultiple displays sections of Displays on Windows, make sure the Extend these displays option is chosen. It’s a good idea to check all your Display settings to make sure they are set up for multiple monitors: Sometimes a Windows update can reset them.
If you find that your games keep minimizing when playing on a single monitor, you might be accidentally clicking in the pane of your second display. Some games don’t lock the boundaries of their fullscreen window, which means that when you move to the edge of the screen, your pointer can transition into the second window.
Check your display options within the game itself: If you’re playing in “Windowed” mode, try switching to “Full Screen” instead, as it captures your mouse. If that doesn’t work, try switching to the “Borderless Window” mode. It won’t stop your mouse from moving to the other screen, but it can stop the game from minimizing when it happens. You’ll just need to click back into the game window.
Turn off the second screen: It’s a little drastic but turning off the second screen when playing games that don’t need it prevents you from drifting into that extended space mid-game. Simply press the display’s power button, or press the Windows + P keys and select the PC Screen Only option.
This can happen if you go into sleep mode or your monitors switch to screensavers, then you open back up. Suddenly, you find that all your app windows or tabs have changed places, often all moving to the first monitor display, ruining your setup, and wasting plenty of time moving them all back. This is a known issue on Windows 10, most likely due to “Rapid Hot Plug Detect” issues, but there are things you can do to fix the problem.
Update to Windows 11: Windows 11 specifically has a new feature to deal with this problem, so if you update you can fix it. In Windows 11, visit the Display setting, and look in the Multiple Displays section. Here you will find an option to Remember Window Locations Based on Monitor Connection. Make sure it’s enabled, and that should solve your problem.
Switch off DisplayPort: You can also switch from DisplayPort to HDMI. This problem appears to be unique to DisplayPort connections, and you may be able to prevent it from happening by using another connection option.
Sometimes your secondary computer monitor will work, but it will encounter distortions and artifacting that make it difficult to use or impossible to play games with. If your first monitor does not have these display issues, then the issue is probably related to your hardware. You can usually fix it by trying these steps:
If necessary, roll back driver updates: If your display driver recently updated, it could be causing the issue. Go to Device Manager, select Display Adapters, and select your display adapter to see more. Go to Properties, look at the Driver tab, and choose Roll Back Driver.

I am using a Dell Latitude Laptop with a Docking Station. Two displays are attached to it via DVI. I am only working with the external screens the laptop is shut.
Now this is a minor problem, but still pretty annoying. When I go to suspend mode (which I do quiet frequently), the displays go off and then want to login again, the second display is turning off and on every few seconds. When I detach the DVI cable at the docking station and then plug it in again, the problem disappears.
The first display works just fine. Does anyone have an idea how to fix this? I guess you can image, that I don"t want to plug off and in the cable, every time I"m going back from suspend.
EDIT: It seems this is indeed caused by the Docking Station. Maybe there is a problem with the Linux drivers, but someone at work told me, he has similar issues with his windows machines. I have found even more display and suspend bugs since then, I think my Dell hardware just doesn"t go well with Ubuntu.

YET AGAIN i get the flicker to occur just like it did with display port thats super annoying and thats when i finally (probably longer than it should have taken) to realize its a timing issue an nothing else
SO I now choose CVT option and boom problem solved. No flicker perfect image all sunshine and bunnies...until you let the display go to sleep and then on wake up it all goes to hell on the custom profile.. so I read on some more and like the OP had success by changing the refresh rate to 35hz...and boom now it really does look and work perfect....except until something moves on the screen and its at 35hz. :/
So I went and switched back to display port hoping the 35hz to solve restart was a HDMI limitation. Now when I choose CVT option the monitor goes to hell immediately when running DP and still has flicker with CVT REDUCED BANK. so now thats out

Okay, I turned off my second screen and it works perfectly fine again. I don"t understand what happened as I had the two screens connected as well a couple of hours before... One of them was turned off though (but still connected). If I try that again, screen still flashes.

OHHH and try this real quick: Hit Windows+P and set it to single monitor. See if that fixes the problem. If it is tied to MPO issues, this might help get to the bottom of the issues. A lot of people will have mismatched refresh rates on displays and it could be that the DWM is getting out of sync with stuff trying to line up frames for the displays.
