Review on 🖥️ DVI 2 Port Manual Switcher Selector Switch Box for Single Mode Monitors - 1920X1080 Resolution - 2:1 Switching Efficiency by Will Murphy

It does exactly what it says it does, does it well, just does it. It's not electronics, it's the same as running cables from one monitor or computer to another. It doesn't matter if it's used for two monitors and one computer or two computers with one monitor. I bought two to use dual monitors with my laptop and desktop. Works perfectly. FYI, switching to another computer is like telling the computer that the monitor is off, so the tabs are rearranged, etc. This is why I put my computers to sleep before switching.
