HDMI & audio KVM switch
I invested in this KVM switch so that I could use a gamer configuration and a Mac mini on the same screen, with the same mouse and keyboard.
It weighs a lot and is very well equipped with HDMI and audio connections.
The result: it works.
I'm not giving it top marks because the documentation was missing when I unpacked it, and because there's no on/off switch.
Otherwise, it's great value for money. I recommend it if you want to use two computers and share screen, mouse and keyboard.
