What the AI looks for in KVM Switches
- Video standard and bandwidth
- The switch must support your monitor's resolution and refresh rate on the same interface (HDMI 2.0/2.1, DP 1.2/1.4) Under-spec switches cap refresh rate or drop signal.
- Monitor count
- One video channel per monitor per computer A dual-monitor setup needs a dual-head KVM and twice the cables.
- EDID emulation
- Prefer switches that keep the monitor visible to inactive computers Without it, windows rearrange or resolution resets on each switch.
- USB handling
- USB 3.0 passthrough for webcams and drives; check whether the keyboard and mouse are emulated or passed through Emulation enables hotkeys but can break gaming mice and macro keyboards.
- Switching method
- Front button, wired remote or hotkey Convenient switching matters when the box sits out of reach.
Brands that matter

What to avoid

- Using a KVM with mismatched cable types and adapters, which commonly break signal
Questions
Do I need a KVM or just a USB switch?
If your monitor has multiple inputs you can switch, a USB switch for keyboard and mouse may be enough. A KVM switches video too.
