Windows 10 Multiple Monitors – Mouse Cursor on Different PPI Screens

mouse-cursormultiple-monitorsresolutionwindows 10

I'm using a 4K display along with a Full HD display with both almost the same physical size and it brings some mouse cursor problems to me working with it on the default Windows settings.

As the mouse movement speed depends on the pixels, it's very slow on the 4K display and very fast on the Full HD display.
Is there a windows setting or application to move the mouse depending on the visible distance and not the pixels?

Another problem is the virtual wall between the screens I can't move the cursor from the upper half of the 4K screen to the Full HD screen:

How is it possible to virtually stretch the cursor transition area of the Full HD screen to the one of the 4K monitor?

The smallest problem, nevertheless painful, is the cursor size which varies between the screens. Is there a way to keep the same visual mouse size on both screens?

Virtual wall

LittleBigMouse fixes the virtual wall problem in its current version, as Flexo013 pointed out in his answer
DisplayFusion provides an option for skipping the Virtual wall in it's paid Pro version - thanks to Ƭᴇcʜιᴇ007 for the link
There is a study published by Microsoft in 2004: Mouse ether: accelerating the acquisition of targets across multi-monitor displays. It finds that mouse ether improved participants’ performance on a target acquisition task across two screens running at different resolutions by up to 28%. Unfortunately, the mentioned application Mouse Ether isn't available for download.

Cursor speed

It appears that Microsoft has finally fixed the mouse speed issue in Windows 10 Insider Preview build 16273 so most probably the fix will be in Fall Creators Update (2017). It is activated by changing the scaling of a screen.

There were three projects which address the cursor speed problem on multiple screens with different resolutions.

DpiGonzales on github which works very well on my system - thanks to Sandor Drieënhuizen for developping the tool and for sharing the link
There is a project called LittleBigMouse on github, which is in alpha state and not stable on my system.
The most configurable program I've found is Custom Screen Speed on its developers website, but the configuration has to be set manually and it is not stored. Therefore it has to be reconfigured at each system start.

Windows – How to disable sticky corners in Windows 10

The thread How to disable sticky corners in Windows 10? from answers.microsoft.com treats this same problem :

When moving the mouse from the left monitor to to the top left of the right monitor the 6 pixel corner will catch your mouse.

I have similar problem in windows 8.1 and changing MouseCornerClipLength in registry to 0 from 6 and disable Corner Navigation in Taskbar and Start menu properties helped.

Anyway in Win10 i can't find MouseCornerClipLength, Corner Navigation disabled at all and adding same registry keys won't help.

The answer on June 4, 2015, by a Microsoft Support Engineer named Vijay B was :

We are aware of this issue and it is currently being investigated. Stay tuned and we will update this thread when additional information becomes available.

If any other posters experiencing this have not submitted this through the Windows Feedback App, please do so. This article http://answers.microsoft.com/en-us/insider/forum/insider_apps-insider_feedback/how-to-share-feedback-on-windows-10-technical/5e501781-a580-43e3-8926-40ae19343805 explains using the Windows Feedback App.

It seems that your only option is currently to wait for a future improvement, or for some hacker to come up with the right hack. Adding your voice to the Windows Feedback App might help.

[EDIT1] The open-source application Non Stick Mouse is said to offer a solution in the case of multiple monitors. The developer states:

What it does is hop the mouse over the sticking corners, as well as the screen edges when moving windows. Thus it allows the dragging of windows through screens without your mouse getting hijacked by the Snap Assist.
[...]
This application does not read or write to any drive, it does not access the registry or connect to the Internet.

Warning: It has been noted in the comments that virustotal finds malware in the latest version of "non stick mouse".

[EDIT2]

I have found a source that gives a solution for Windows 10 (which I'm unable to test now):

Disable Snap
In Settings > System > Multitasking, set Snap to Off.

Registry modification
Create and execute the following .reg file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]
"MouseMonitorEscapeSpeed"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\EdgeUI]
"MouseMonitorEscapeSpeed"=-

Windows – Mouse cursor much larger on secondary displays

Try following (specially 1st and 7th)

Change theme : change to OOTB theme(like Windows Black) and check again
Try with different user account : Most of the times this will solve your problem. I am not saying this is final solution but you will narrow down the issue.
Try the test in safe mode : If it works in safe mode then the issue is with some running service that we need to identify.
Restore to earlier system restore point and test What I am trying to say is this issue might be specific to some of your user specific setting / service.
Run antivirus check just to be on safer side.
if any other screen is easily available then try to test with new screen (although I think this is very unlikely the cause) so that you can conform that issue is not with hardware. also there is a setting to reset the monitors try that one as well.
If your monitors are rotated monitors. Setting the rotation to normal and then setting it back to 90 degrees seems to resolve it.
Disable pointer shadow within the cursor menu

Hope this helps.
