Little Big Mouse

Little Big Mouse (LBM) is an open-source software designed to enhance the multi-monitor experience on Windows 10 and 11 by providing accurate mouse screen crossover location within multi-DPI monitors environments. This is particularly useful for setups involving a 4K monitor alongside a full HD monitor.
