Do you get tired of battling screen flickering on your Dell monitor? Monitor flickering is currently one of the most annoying display issues you might encounter. Diagnoses can be challenging because monitor flickering takes many different forms. Your display may be flickering for a variety of reasons, so the fix is not as straightforward as cleaning your monitor. Although it might be software-related, it could also be hardware-related, like problems with the connections on the screen. This issue is fairly common, so whatever the cause, it can be easily fixed.

Monitor Flickering

A screen flickering issue may be caused by a variety of factors, such as hardware damage, software issues, and bugs in particular applications. Malware and setting modifications can also degrade the performance of your computer or mobile device’s screen. Particularly when you are using your computer to work or play games, monitor flickering can be inconvenient and distracting. Your computer’s monitor flickers when it rapidly turns on and off.

Display drivers frequently lead to screen flickering in Windows. You must launch your computer in safe mode, remove your current display adapter, and then search for display driver updates. 

Why Is My Monitor Flickering and How To Fix It

You can access Task Manager to help identify the cause because there are several causes of a flickering display. Observe the steps below to launch Task Manager and determine the cause of your monitor’s flickering:

  1. Launch Task Manager on Windows 11 by first performing a right-click on the Start menu and selecting the option.
  2. Check to see if the Task Manager flickers while running.
  3. Other items on the display may flicker even though the Task Manager window isn’t, which indicates that an app(s) is/are to blame.
  4. If the Task Manager window is flickering, the problem is with your graphics card or GPU driver.

#1. Inspect Your Ports and Cables

Unstuck or broken cables or ports are among the simplest and most common causes of monitor flickering or ghosting. If your monitor is attached to your computer or power source by a cable, make sure the cable is firmly plugged in and is not bent or frayed. Verify the compatibility and functionality of any adapters or splitters you use. To see if the problem still exists, you can also try using a different cable, port, or adapter. Flickering can occasionally be brought on by a malfunctioning or incompatible cable or port that obstructs the signal’s transmission.

#2. Adjust Your Refresh Rate and Resolution

An incorrect or incompatible refresh rate or resolution can also result in monitor flickering or ghosting. Counted in hertz (Hz), the refresh rate is the frequency at which your monitor updates the image displayed on the screen. The number of pixels that make up an image on a screen is referred to as resolution or pixels per inch (PPI). Flickering may result from a refresh rate or resolution that is too low or high for the monitor.

The rate at which a monitor updates its display once every second, expressed in hertz (Hz), is known as the refresh rate. Basic monitors typically only support refresh rates of 60Hz, whereas more sophisticated models—typically targeted at gamers—can reach refresh rates of 360Hz and higher.

This can be fixed by adjusting the refresh rate and resolution to the capabilities and specifications of your monitor. You can accomplish this by going to the display settings on your computer and choosing the recommended or ideal option for your monitor.

To adjust your refresh rate:

  • For Settings to appear, press the Windows key + I.
  • Press System > Display.
  • Depending on whether you are using Windows 10 or 11, choose Advanced Display Settings or Advanced Display.

To stop the screen from flashing, use the dropdown for the refresh rate and gradually select lower rates. Revert to the monitor’s suggested refresh rate if the flashing persists.

#3. Maintain Software and Driver Updates

When drivers or software are out-of-date or corrupt, this can sometimes result in monitor flickering or ghosting. Drivers are software programs that give your computer access to your hardware, such as your monitor, and enable communication. The operating system, browser, and games are examples of software—applications that run on your computer. Flickering or ghosting may occur if your monitor’s drivers or other software are out-of-date or incompatible. Update your software and drivers to the most recent versions, and then search for any errors or inconsistencies to resolve this. To do this, launch the device manager program on your computer or go to the manufacturer of your monitor’s website and download the necessary drivers and software.    

#4. Recalibrating the Monitor’s Settings

Monitor flickering or ghosting could also be caused by incorrectly calibrated monitor settings. To create the most accurate and high-quality images, your monitor must be calibrated, which entails adjusting its brightness, contrast, color, and gamma settings. Monitor settings that are too high or low can cause flickering or ghosting. You must correct this by calibrating your monitor settings to your viewing environment and personal preferences. This can be done using the menus and buttons on your monitor, as well as a calibration tool or piece of software running on your computer.

#5. Switch Out Your Components or Monitor

The possibility of a hardware issue with your monitor or other components exists if none of the previously mentioned fixes work. Wear and tear, physical harm, overheating, power surges, or other factors may result in hardware issues. Faulty backlights, panels, boards, inverters, capacitors, and other common hardware issues can result in flickering or ghosting. You must buy a new or functional monitor or other components to resolve this. To do this, get assistance or warranty service by getting in touch with the manufacturer or a qualified technician. 

#6. Examine the Display Cable.

One of the primary causes of flickering monitors is a damaged HDMI or DisplayPort cable. Even older VGA and DVI cables are susceptible to this annoying problem, so it is crucial to check that the cable is not only securely fastened but also free from any flaws. Start by connecting the cable to another device or replacing the monitor’s cable altogether.

#7. Check Display Settings

Altering the display settings is another common cause of monitor flicker. Making a few minor changes to your display settings can produce several annoying artifacts, including monitor flicker.

Verify that none of the settings have been altered by visiting your NVIDIA control panel (or AMD Software: Adrenaline Edition if you are using AMD). The “Change Resolution” tab of this menu, which gives you the option to change the screen resolution and refresh rate, should be your primary focus.

Ensure that your refresh rate is at the highest setting for the best experience. Uncomfortable visual artifacts could result from a lower refresh rate.

A right-click on the desktop and a drop-down menu will appear; select Windows Display Settings to see if any settings have changed.

#8. Reseat Your Graphics Card

Even if your display driver is working properly, the problem may still be with your graphics card. Incorrectly seated graphics cards in motherboards can cause the monitor display to flicker on and off.  

Removing the monitor cable from your graphics card will allow you to plug it into the motherboard’s display slot. You should use the motherboard’s display slot to attach the monitor cable rather than your graphics card. You can tell the graphics card is the issue if the flashing stops.

Close the case, turn off the computer, unplug everything, and then take the graphics card out of the motherboard. Reinstall it carefully this time, making sure the card is securely clipped into the motherboard. Of course, you should not attempt this if you are not accustomed to working on a computer because you risk making matters worse.

#9. Removal of Problematic Programs

Some apps can make the screen flicker because they are incompatible with Windows 10 or 11. Consider whether any recent app updates or new software installations were made before the screen flashing started. Previously, Norton Antivirus, iCloud, and IDT Audio were three unreliable applications.

Ensure that the most recent versions of all your applications are installed. Update either through the app itself or by visiting the relevant official websites and downloading the most recent version. If it is determined that screen flashing is a recent bug, another option is to look at the developer’s support page for any recently updated apps.

If that does not work, remove the application. To do so:

  • To access Settings, hit Windows Key + I.
  • Simply select Apps > Apps & Features.
  • Select the Installation date from the Sort by menu.
  • Click Uninstall next to the offending app. The changes might not take full effect until you restart your computer.
