The only KVM you need for a dual-computer setup.

It needs DDC/CI, a small VESA standard the OS uses to talk to your monitor over the existing video cable. Almost every monitor made after ~2015 supports it. If yours has on-screen menu buttons on the front, it almost certainly works. The troubleshooting page covers the known exceptions, and the 3-day trial will tell you for sure (and you have a 14-day refund either way).

A traditional hardware KVM switch is a physical box that sits between your computers, your monitor, and your USB peripherals. You buy one matched to specific ports and resolutions, wait for shipping, and re-plug cables. EasyKVM does the same thing in software: each computer drives the monitor directly (so no signal loss or refresh-rate caps), and the keyboard and mouse hand off over your LAN.

Synergy, Barrier, Input Leap, Deskflow, Logitech Flow, and Mouse Without Borders share a keyboard and mouse between computers that each keep their own monitor. None of them switch a shared monitor's input. EasyKVM is built for the other setup: one monitor split between two computers. The same hotkey flips the monitor over DDC/CI and hands off keyboard, mouse, clipboard, and audio together. It also works if you keep two screens. Turn the Monitor toggle off in Remote Control and you get the same handoff on a deliberate hotkey, with no cursor crossing an edge by accident and nothing to fight when a game captures the mouse.

Entry-level hardware KVM switches start around $40–80 and almost all of them cap at 1080p / 60 Hz on at least one of their ports. To get a 1440p or 4K hardware KVM that handles 144 Hz you're looking at $200+. EasyKVM is $29.99 once, drives whatever your monitor's native input handles (4K, HDR, 240 Hz, all fine, because each PC connects to the monitor on its own cable), and it ships immediately. If "cheap KVM switch" is what brought you here, this is the cheapest path that doesn't compromise on display quality.

EasyKVM does exactly that. Install on both machines, pair them with a 6-digit code (one-time), then press your swap hotkey (default Ctrl+Alt+Q) to hand the keyboard and mouse off between them. Same physical keyboard, same physical mouse, two computers. No cables to unplug, no hardware required. Works over your local network at sub-50 ms latency. The 14-day refund means you can verify it works on your specific Mac + PC combo before committing.

You can still use EasyKVM as a pure keyboard + mouse + audio sharing tool. In Settings on the host machine, turn off "Swap monitor input on hotkey." The swap hotkey now just toggles Mirror Peripherals: your keyboard and mouse hand off between machines, and you switch the monitor input manually (its physical buttons, or however you usually do it). Useful when DDC/CI doesn't work for you: USB-C dock pass-through, older monitors, laptops where you only have one screen anyway.

Yes, whatever your monitor, GPU, and cable already do. EasyKVM never touches the video signal: each computer is plugged into the monitor on its own native input (HDMI, DisplayPort, USB-C), and we just tell the monitor over DDC/CI which input to display. No shopping for a hardware KVM that advertises 144 Hz, only supports it on one port, and ships with a cable that can't carry it. With EasyKVM there's no port to spec: the signal goes computer → monitor, full speed.

Yes. Add each extra monitor in Settings on the Windows host with its own input mapping, and the swap hotkey flips them all together. And if some screens should stay put (say, a laptop panel), just don't add them, only the monitors you configure swap.

No. Any two computers work: Mac ↔ Windows, Windows ↔ Windows, or Mac ↔ Mac. Either side can be the host: the machine that runs your license; the other computer joins over the LAN without a license. Automatic monitor input switching (DDC/CI) runs on a Windows machine, so Mac ↔ Windows and Windows ↔ Windows desks swap the monitor automatically. A Mac ↔ Mac pair shares keyboard, mouse, audio and clipboard, and you switch the monitor input manually.

Yes, as long as both machines are on the same LAN. Ethernet on at least one side gives you the snappiest mouse feel, but Wi-Fi 5 / 6 is fine for typing and everyday use.

Audio is bidirectional: it follows whichever computer is in control, in either direction (Mac → PC and PC → Mac). On Mac we capture with ScreenCaptureKit; on Windows, WASAPI loopback. You can disable it in Settings if you'd rather keep audio local.

3 days of full functionality, no credit card, long enough to confirm it works on your hardware. After that the host machine needs a license: paste the email and the license key from your purchase into Settings → License on the host. The other computer doesn't need a license or an account; it just joins on the LAN.

No. One license covers one host machine. Any computer on the same LAN can join it as a client: no extra license, no extra account. Move the license to a different host with the “Change host” action in your account (available once every 30 days).

14 days, no questions: that's the EU consumer-law right of withdrawal, and we honor it everywhere. If your monitor doesn't expose DDC/CI or anything else surprises you, email support@avendavi.com with the email you used at purchase.

Strictly two machines per pair right now: one host and one joiner, and either side can be the Windows PC or the Mac. Multi-joiner support is something we'll look at once the two-machine flow is rock solid.

EasyKVM is in beta: expect a few rough edges. The troubleshooting page covers the most common issues people hit (DDC/CI compatibility, Mac permissions, stuck modifiers, license activation) with the fix for each. If yours isn't there, email support@avendavi.com and we'll add it.

No usage analytics, no crash telemetry. The app talks to three things and nothing else: your peer machine over LAN, the GitHub releases server when it checks for an update, and our license server about once a week to renew your license token. Your keystrokes, mouse movements, audio, and clipboard never leave your network.
