Streamline Your Workspace: Tackling Screen Lag in Windows

Laptops are great for portability, but they often have small screens. While you can easily connect an external monitor to your Windows laptop to get more screen real estate, this can sometimes cause unexpected problems, such as lag or performance issues.

Below, we will explore several effective troubleshooting tips that can help resolve performance issues with your Windows laptop when it is connected to an external display.

1. Make Sure Your Laptop Is Compatible With the External Monitor

One of the most common reasons why your Windows laptop may lag is if it lacks the minimum hardware requirements to support the monitor. This usually happens when your laptop’s graphics card isn’t powerful enough to handle the monitor’s resolution. Try lowering the resolution of the external monitor to see if that resolves the lag.

Both native 64-bit and 32-bit builds are available, and moreover, the 64-bit includes separate builds for SSE2 (128-bit), AVX-2 (256-bit), and AVX-512 (512-bit) instruction sets. New versions support AI-assisted writing.

2. Change the Screen Refresh Rate

A monitor’s refresh rate is how many times per second the screen updates the image. If your laptop’s graphics card or integrated graphics is not powerful enough to handle the monitor’s higher refresh rate, it may have difficulty keeping up with the increased frame output, which can cause stuttering or tearing in the image.

You can try changing the refresh rate for your monitor to see if that solves the problem.

1. Press Win + I to open the Settings app.
2. Head to System > Display > Advanced display.
3. Click on Display adapter properties for Display 1.
4. Switch to the Monitor tab and click the drop-down menu under Screen refresh rate to select 60 Hertz.
5. Hit Apply followed by OK.

Allow the troubleshooter to detect any issues and fix them. After that, check if your Windows laptop still lags when connected to an external monitor.

4. Close Unnecessary Apps and Programs

It is likely that the performance issues you are experiencing are caused by the apps and programs running on your PC. You can try closing unwanted apps and programs to see if that solves the problem.

Press Ctrl + Shift + Esc to open the Task Manager. In the Processes tab, locate and select the program you don’t need and click the End task option at the top. Close all unwanted apps and programs and check if you still experience lag.

5. Try Some Generic Fixes

Still having problems? Don’t fret, you can try the following generic solutions to solve the problem.

• Update Your Graphics Drivers: An outdated or incompatible graphics driver may be the cause of your Windows laptop lagging. Hence, it’s a good idea to update the graphics drivers on your PC if you have not already done so.
• Try a Clean Boot:Performing a clean boot can help you determine if a third-party program or service is causing your Windows laptop to lag. If you do not experience any lag while in a clean boot state, you will need to uninstall any suspicious apps or programs to fix the problem.
• Install Windows Updates: A buggy Windows build can also cause such anomalies. As a last resort, try installing any pending Windows updates to see if they resolve the issue.
