1. Boost the computer’s performance
When it comes to the computer, there are several methods that could help you boost its performance, both temporarily and in the long run. If you face mouse lag on an external monitor not too frequently, it could be a background process that leads to the problem.
Check if there’s a Windows Update in progress, or another application or process consuming a lot of resources. If yes, terminate it in the Task Manager and check if the problem is solved.
Also, if the RAM is heavily loaded and there isn’t much space left on it, you are bound to face mouse issues on a 4K monitor. To combat this, use an effective RAM cleaner tool.
2. Update the drivers
- Press Windows + S to launch the Search menu, enter Device Manager in the text field at the top, and click on the relevant search result.
- Next, double-click on the Mice and other pointing devices entry.
- Right-click on the malfunctioning mouse, and select Update driver from the context menu.
- Select Search automatically for drivers from the two options in the Update Drivers window.
- Now, wait for the system to search for the best available driver and install it.
It is necessary to regularly update the drivers for the device to function effectively. This is all the more important for the critical ones, such as the Graphics driver, and those for the regularly used peripheral devices.
In case the update didn’t go through using the Device Manager, you can try manually installing the latest driver version in Windows 11. Also, do not forget to update the graphics driver and that for the monitor, especially if you are facing mouse lag on Dell 4K monitor.
Additionally, if you still need a more efficient and automated method to update your mouse driver or any other drivers, you have dedicated driver updater software.
