Finding my best mouse keyboard sharer

After using laptops for years, I finally bought a desktop PC for my study and work. My desk space is too small to place a keyboard. And to fully utilize both computers, I feel the need to do something to connect between them. When using only one PC, I can use Windows built-in Miracast or Spacedesk to share the display. However, when using both PC simultaneously, I need something to just share the mouse, keyboard, and hopefully audio.

My setup is like below. If possible, I'd use the laptop for control completely as I prefer the trackpad to the mouse. Desktop's mouse is used for gaming and 3D software.

  • Desktop: Windows 10. A wireless mouse. No keyboard.
  • Laptop: Windows 10. Builtin keyboard and trackpad.

    • No lag over Ethernet.
    • Support two-way control. I can use my desktop PC's mouse to control my laptop's mouse cursor, and can also use my laptop's trackpad to control my desktop PC. But, to make the keyboard works on another PC, you need to move the mouse onto it first, or press Ctrl + Alt + F1. I can understand why it's designed like this, but in my use case, it just adds an extra step.

    Con

    • When switching between mice, the mouse cursor will take a jump. This may be because my laptop display is 4K.
    • Supports trackpads but not Windows precision touchpad fully. Pinch to zoom is supported partially. Doesn't work very well with multi-finger gesture software, GestureSign. It sometimes works and sometimes does unexpected things. I found the issue ticket in GitHub.

    • Just can't make it work. Didn't know why but because the con below, it doesn't fit for my use case so I didn't continue to try.

Finally, I settled with Mouse without Borders, mainly for its 2-way control support. Also, I hacked GestureSign to make it work with Mouse without Borders, so now I could use some of gestures from my laptop, which keeps my workflow.
