# KVM Switch EDID Explained: Why Displays Reset When You Switch

> Decide whether persistent display identity is important for the workflow, then verify how the exact KVM handles inactive inputs and multi-monitor EDID. Separate EDID emulation from ordinary signal switching and from USB keyboard/mouse emulation. The acceptance case is understanding the display-identification behavior that determines whether each computer thinks the monitor stayed connected during a KVM switch. The failure to guard against is this: without the right display-state behavior, an operating system can treat the monitor as disconnected, rebuild the desktop, choose a different mode or lose a preferred refresh setting.
