Startup Idea: Adaptive Mouse Cursor Sizing Software

Startup idea to develop a software program that can link your mouse cursor size to any application in use, allowing it to adjust automatically based on the program that's active on a 5k large screen, solving the visibility and convenience issue faced by users.

A lot of times when I use software, if I use my 5k large screen, the mouse cursor will not resize, and results being tiny and hard to find/see. A software program that can link your mouse size to any program you are using, and make it adjustable would be super helpful!. I tried googling this.
