There are multiple input (5xHDMI) same output (1x HDMI) switches on the net, which feeds one input of the monitor and you can change the source on the adapter with a round robin button. It's almost instant. Another cool feature is whenever a new input source is detected it automatically feeds that to your monitor. I haven't seen the configuration you need, but if you can use adapters to convert each source to HDMI, it works like a charm. It's called an HDMI switch.
