Disable mouse speed check between monitors in windows 8.1 update 1

Question

In windows 8.1 and below, the mouse would seamlessly move through all my monitors.

However, in windows 8.1 update 1 the mouse needs to be going at a certain speed before it goes to a different monitor. How do I disable this?

A google search has turned up nothing, so I'm not sure what exactly is going on

Answer 1

@Jason Stevenson's solution worked best for me, however I found a case when it does not work as expected.

This MouseMonitorEscapeSpeed value does not seem to be a True/False toggle with 0/1, but more an integer value. A value of 1 does not fix this issue in all scenarios moving from monitor to monitor.

To reproduce the issue when using 1 for MouseMonitorEscapeSpeed

1. Set both MouseMonitorEscapeSpeed registry entries to 1
2. Reboot the machine or restart the Explorer.exe process
3. Turn off taskbars on multiple displays (as shown by @vanquishuk)
4. Unlock the main taskbar and move it to the right side of the left monitor
5. Move the mouse very slowly from the left monitor to the right one (you should see the mouse get stuck for a little bit in between)
6. Moving from the right monitor to the left and the mouse does not stick

With the below registry entries I have found the solution works in all scenarios I can think of (including having the taskbar on the side of your monitor).

--- Registry File ---

Windows Registry Editor Version 5.00

;
; Fix mouse stickiness between monitors and mouse getting stuck in corners between monitors
;

[HKEY_CURRENT_USER\Control Panel\Desktop]
"MouseCornerClipLength"="0"
"MouseMonitorEscapeSpeed"=dword:00000000

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\EdgeUi]
"MouseMonitorEscapeSpeed"=dword:00000000

Answer 2

The selected answer no longer solves the issue on the most recent Windows 8.1 updates, or in Windows 10.

To properly solve this issue in later Windows versions you must edit this key here, changing the value from 0 to 1:

HKEY_CURRENT_USER\Control Panel\Desktop\MouseMonitorEscapeSpeed

And you must also add a missing key to the following location:

HKCU\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\EdgeUI

Create a DWORD value MouseMonitorEscapeSpeed set to 1

Finally you must kill the Explorer.exe process from task manager, and then re-launch it; alternatively you could restart your PC for the change to take affect.

Found a way to fix it for my self. Un-check this box: Right click task bar > Properties > Task bar Tab Once un-checked hit apply, then you can re-check it and hit apply again and the mouse should no longer get stuck.

Answer 4

While some reported that this problem disappeared after changing seemingly unrelated windows settings (such as the "Show taskbar on all displays"), none of this worked for me.

However, after changing the registry value

    HKEY_CURRENT_USER\Control Panel\Desktop\MouseMonitorEscapeSpeed

from it's default value (0 on Win 8.1 Pro build 9600) to 1 and rebooting the "sticky edges bug/feature" seems to be gone.

There is also MouseCornerClipLength in the same location which might be of interest if you want to disable the sticky corners too (set it to 0 in that case).

EDIT After changing MouseMonitorEscapeSpeed back to 0 the problem appeared again after hibernation. Value 1 seems to disable sticky monitor edges without any side effects.

Answer 5

If anyone still has this issue in windows 10. Check in Settings->Display to make sure your screen arrangement is as tight as possible (smallest possible gaps). When there is a big gap, the mouse will require a proportional amount of additional pixel movement to reach the next screen (Moving the mouse faster based on the size of the gap).

Answer 6

On Windows 10, go to:

Control Panel\All Control Panel Items\Ease of Access Center\Make the mouse easier to use

which I found by searching settings for 'edge'.

Check the box for Prevent windows from being automatically arranged when moved to the edge of the screen.

Answer 7

I've found a solution that does not need an explorer.exe restart or system reboot.

Steps:

1. go to start screen
2. click a metro app (onenote in my test case)
3. move mouse to top left corner and click so it switches app (to desktop or to another metro app; doesn't matter)

Now mouse will be sticky thru out ALL edges of the monitors.

It comes from user Riasat from MS forum: http://answers.microsoft.com/en-us/windows/forum/windows8_1-tms/mouse-stickiness-change-with-multiple-monitors/a4eb4cc9-def1-4e80-b823-83460339afb8

You can close the metro app after it or kill it through task manager.

Hope this will help you it's really annoying bug O.o
