Mouse lag when laptop is hooked up to an external monitor

Hi,

The above issue might occur due to non-updated mouse drivers installed or if any third party application/program is conflicting with the mouse drivers installed on the computer.

Before we assist further, I would like to ask you a few questions:

1. Does the issue persists only on connecting an external monitor to the computer?
2. Did you check if similar issue persists on connecting an external mouse to the computer?

Method 1: If haven’t tried, check if similar issue persists on connecting an external mouse to the laptop. If the issue does not persists, update touchpad drivers manually from Device manager by following the steps below and check if the issue is resolved.

1. Press Windows logo + X keys on the keyboard and select Device manager from the context menu.
2. Expand Mice and other pointing devices option and check if touchpad driver is located. If yes, right click on the driver and select Update this software from the context menu.
3. Follow the on-screen instructions and wait for the update to complete.
4. After the update is complete, close the window and check if the changes are effective.
5. If the issue persists, download and install the latest and most compatible device drivers from the manufacturer’s website and check if the issue is resolved.

Method 2: If the issue persists, boot the computer in Clean boot state and check if any installed third party application/program is causing the issue.

Putting the system in Clean boot will enable the PC to start using minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows 10, Windows 8.1, Windows 8, Windows 7, or Windows Vista.

Refer to the section How to perform a clean boot for Windows 10 from the article.

Disclaimer: Start the computer in normal mode refer the section, How to reset the computer to start normally after clean boot troubleshooting from the link above.

Hi Likhitha,

Thank you for your reply. The answers to your questions are;

1)It only lags when an external monitor is connected. Either extending my display over two screens or just having the external monitor as my main screen.2)This mouse worked perfectly on Windows 7 and on my partners Macbook Pro.

Cheers,

J

I have Asus laptop. I tried to reinstall mouse drivers with no result.

My mouse is lagging on built in display when I have connected external monitor through hdmi. Mouse is lagging only over windows desktop. Mouse is NOT lagging when it is over any window.

I have 4k display (build in), but I am using only full HD resolution. External monitor is only full HD.

EDIT: I find out that even video on that screen is lagging when I move mouse over desktop.

Hi,

Have the same problem. The in-built trackpad on my laptop performs without a glitch, but mouse keeps stuttering. This happens only when an external display is connected. The problem does not depend on the mouse driver it seems (Microsoft wireless mouse 4000 with the latest control center and an old Logitech, both have this issue). I reckon the problem is somewhere between mouse driver and display output. Somebody should look into this seriously, as there appears to be a large number of people having this issue.

Best,
