How to Fix Screen Flickering for Laptop & Desktop Monitor?
Screen flickering in a laptop or desktop is a visible change in the brightness between cycles displayed on the screen. This constant blinking on the screen may be a real frustrating thing as it destroys the peaceful watching experience.
Fixing screen glitching doesn’t always mean taking the laptop or monitor to the service center, most of the time we can only fix the problem. Let’s see what are the reasons for screen flickering and solutions for the same.
Reasons for Screen Flickering:
In an old PC due to wear and tear as years pass by, and defective old cables due to aging are the main reasons for this problem.
But in new computers screen flickering happens due to many reasons, defective wires may also be one of the reasons. Some of the common reasons for screen blinking are:
• Outdated Display Drivers:
Outdated display drivers can cause screen flickering, poor display resolution, and other problems. Your laptop will suffer if the drivers are outdated when the patches, updates, and bug fixes go by sideways.
Here’s how to check for an update and also update if the drivers are outdated.
Go to Settings, in the Windows task button, select the Update & Security tab. Then the laptop will scan automatically for updates and shows the updates if any.
If your laptop doesn’t scan for updates automatically then we can do that by clicking on the Check for Updates tab. If there are updates then proceed to update the drivers by clicking the Install updates icon.
• Installation of Incompatible App:
Sometimes we install applications that are of high specifications and parameters, and the computer may not able to handle them.
In such cases, screen flickering is quite common. To check the app which is incompatible with our PC, we need to go to Task Manager and check if the screen flickers.
If everything flickers except the task manager then there’s an incompatible in the system, if the task manager also flickers long with everything else then this has a separate issue.
As said above outdated display drivers can cause screen flickering, so we may need to check for an update. You must update your HP, Dell, Lenovo, Acer, ASUS, Sony Vaio, Samsung, and Toshiba laptop display drivers first.
Here’s how to check for an update and update if the drivers are outdated, first we need to boot the laptop in safe mode and uninstall the current display drivers and install updated drivers.
• How to Boot in Safe Mode: Open Settings, select Updates & security, select Recovery, then under Advanced startup select Restart now, this will reboot the PC and takes us to troubleshoot screen, select Advanced options, then select Startup Settings, and press Restart. Once the PC restarts, press the F8 key to enable Safe Mode.
• How to Uninstall Current Display Driver: First right-click on the Windows taskbar to access the Power User menu, and select Device Manager, this extends the display adapters tab to see the PC’s active display devices.
Right-click on the current display adapter to access an operation task list, then press Uninstall device, then a box with delete the driver software for this device pops up, check the box and press Uninstall, and then restart the PC.
• How to Reinstall Display Drivers: First right-click on the Windows taskbar to access the Power User menu again, select Updates & Security, then under the Windows Update tab select Check for Updates to download and install updated display drivers.
2. Disable Windows Desktop Manager:
Windows Desktop Manager’s processes may also be responsible for the screen flicker. To disable Windows Desktop Manager we need to access the Power User menu by right-clicking the Windows taskbar, selecting Run, then typing services.msc in the Run dialog box.
Then find Windows Desktop Manager, Session Manager, and right-click on it and select Stop, then right-click on Desktop Windows Manager Session Manager again, select Properties, under the General tab, modify the startup type to Disabled, and then press Ok.
3. Optimize the Refresh Rate:
Refresh rate is a measurement of the number of times the screen redraws in a second. If the refresh rate is set more than the preferred value (this usually occurs when we connect our PC to an external monitor) then the screen appears to be flickered but actually, we are just seeing the slow video processing.
To fix this, right-click on the Windows taskbar to access the Power User menu, select Settings, select System, then select Display on the side taskbar, then under Multiple displays select Advance display settings, then observe the refresh rates of both the screens and press Display adapter properties to alter refresh rate of either of the screens.
If all the above technique fails, then we are left with only one option, i.e. visiting the service center and getting the laptop repaired. You can try this only on Microsoft Windows HP, Dell, Sony, Lenovo, Acer, Samsung, ASUS, and Toshiba PCs and laptops.
