So I read somewhere that unplugging the hdmi cable while your ps4, tv, pc etc is still running can damage the device but the thing is, I want to switch between my monitor displaying my ps4 and pc on the fly while they are both running. So if I'm dl'ing something on ps4 I can switch to my pc which is my main gaming platform while the ps4 does it's thing. Now I'm wondering, if I get an hdmi switch, would it still be doing the same thing as just pulling the cord out and risking damage or is it somehow a safe way of swapping between devices that are all powered up?
