When does a laptop screen flicker
Laptop screen flickers
If the laptop screen is flickering it can be a headache in several ways. It can harm your work because the constant blinking is a distraction that creates fatigue. The result is decreased productivity. Frequent breaks are necessary to reduce the possibility of eye pain and headaches. There are several types of flicker, including short, random, and persistent flicker. The way the laptop screen is flickering is helpful in determining the cause.
Adjust the refresh rate
If the laptop screen flickers, the refresh rate should first be adjusted according to the capabilities of the monitor. The refresh rate is a measure of how often the screen is refreshed every second. While this setting applies to older desktop monitors, it can also affect the quality of the liquid crystal displays in laptops. For laptops with Windows operating system:

- Right-click on the desktop and select "Screen resolution".
- Then click on "Advanced Settings" and "Monitor".
- In the menu, check the box next to "Hide modes that this monitor cannot display" and select a higher update rate from the list.
Update of the graphics card driver
This is the most likely cause if you have always had a flickering laptop screen problem. In Windows, the "Device Manager" can be found in the Control Panel under "Hardware and Sound". The exact brand and model of the graphics card can be seen under "Display adapter". In the next step, you can search for this model on the manufacturer's website in order to download the corresponding drivers. Alternatively, there is the option of using an older driver. This is recommended if the laptop screen flickers after an update has been carried out beforehand. In the device manager, right-click on the adapter and then click on "Driver". "Reset driver" restores the previous version and the laptop screen flickers should be resolved.
Laptop screen flickers when playing
If the laptop screen flickers when playing games that use DirectX or OpenGL technologies, Vertical Sync can be activated to stop the flickering. Vertical Sync, or VSync, synchronizes the application's refresh rate with the screen's refresh rate. This reduces the horizontal flickering, which improves the image quality. For Nvidia cards, VSync can be found under "Manage 3D settings". For Intel graphics cards under "3D Settings" or "Asynchronous Mirroring". "Wait for Vertical Refresh" must be activated for ATI / AMD cards.
