Review on Dell S2721HS: HD Ultra Thin Monitor with FreeSync and IPS Technology by Tim Luna

I bought this monitor to connect my wife's home and work computers to one monitor. However, the active switch only works if one of the HDMI inputs has failed; Aside from tiny hidden buttons in the bottom right of the screen, there's no way to choose between two active HDMI sources. A computer must always be off for autoselect to use a different signal. It would be nice to add some kind of software-controlled switching function.
