High-end KVM switches add negligible input lag (often <1ms) that is imperceptible in competitive play. Prioritize KVMs with DisplayPort 1. 0+ to support high refresh rates and 1000Hz+ . A Keyboard, Video, and Mouse switch, commonly referred to as KVM, is hardware equipment that lets users fully control multiple computers with a single set of peripherals.
