DisplaySwitcher
Switches your monitor's input with a software button instead of its physical buttons.
DisplaySwitcher sends the 'switch video input' command to any monitor that supports the DDC/CI standard, so switching source — and moving your KVM-enabled keyboard and mouse with it — is one click instead of reaching for the monitor's own buttons. It runs on Linux, macOS and Windows, and as a side effect of running on every machine, it also lets you drag-and-drop or copy-paste text and files between your computers. It's $5.95 a month with a one-month free trial, and you cancel yourself from the account page, no contact needed.
What holds up
- +Works across Linux, macOS and Windows, which solves the gap when a monitor maker only ships one OS's app.
- +Transferring text and files between your computers comes free as a side effect of the same app.
- +Cancel the subscription yourself from the account page — no need to contact anyone.
Mind the limits
- −Needs a monitor with DDC/CI support — older or budget monitors without it won't work.
- −$5.95/month for what is fundamentally a button-press shortcut — a recurring cost for a one-time problem.
