I have Z3660 accelerator board on my A4000D which includes RTG with HDMI output. I wanted automated solution which would automatically switch between RTG and Native graphics, which ever is currently in use.
You connect both Amiga video outputs to inputs, then output to monitor. You will also need signal from amiga which tells which video output is currently active. You can get that signal from Parallel or Serial port with help of this progam https://aminet.net/package/driver/moni/switchcontrol and if you have Z3660, configure Sel signal on in zTop.
Wiring is simple. With parallel port connect pin 13 (SEL) to Sw pin and pin 25 (GND) to GND pin. NOTHING to 3.3v pin. First ofcourse you have to desolder the switch from the board. GND is closest to edge of the PCB and Sw pin is the middle one. Only HDMI 1 LED will be on when HDMI 1 is active, LED off HDMI 0 active.

Link to datasheet https://www.ti.com/lit/ds/symlink/ts3dv642.pdf which states that chip used is 5V tolerant.
Also, Fusion file included for easy modification. In my version, I used M2.5 heat inserts and M2.5 screws.
