How to fix
Mouse lagging on the second monitor
on Windows

Hello. When I push my mouse pointer to the second monitor, it starts lagging. The main display works fine. Is there any way to fix this?

When using multiple displays to increase productivity and multitasking, users may find it annoying to have mouse lag on a second monitor in Windows. Although adding an additional display can greatly increase workspace productivity and organization, this particular issue can degrade the user experience as a whole.

On the second display, the problem appears as a lag or delay in mouse movement, which makes it feel less precise and responsive. When users try to drag and drop items, navigate among applications, or carry out any other action requiring precise cursor control, this lag can be very inconvenient. The fluidity and ease of multitasking that numerous monitors are supposed to provide are disrupted.

Additionally, mouse lag on the additional monitor can result in less productivity and more annoyance. Users can discover that they need to change their workflow frequently, struggle to line up windows and apps, and encounter delays that disrupt their workflow. This not only reduces productivity but may also cause unneeded stress and make computing less fun.

Users frequently need to troubleshoot their system settings or device setups in order to solve this problem. It's important to keep in mind that correcting this issue can differ based on the unique hardware and software setup, even though potential solutions may involve tweaking display settings, updating graphics drivers,[ref en-1] or ensuring sufficient power supply to USB ports. As a result, users would need to investigate several troubleshooting techniques to discover the best answer for their unique situation.

You can also run a maintenance tool like [d1] that can fix most system errors, BSODs,[ref en-2] corrupted files, and registry[ref en-3] issues. Otherwise, follow the step-by-step instructions below.
