I have a NintendoSwitch on an HDMI switcher with other things (WiiU, Playstation, etc.)

It's annoying because sometimes, the Switch, when docked, will 'ping' the HDMI Switcher, switching the HDMI ouput to the switch while you are in a epic MGS5 fight.

Is there a way to stop it from doing that? Right now our solution is to leave it out of the dock, but that makes it out of battery when we want to go out with it.

So is there a way to prevent that HDMI Ping while the Switch is docked?

  • What is the deal with this HDMI pinging I keep hearing about? I've heard some other people having problems with it doing something similar without a HDMI switcher.

  • Looks like it may be a TV issue. One support page showed it was a Samsung issue. Also, updating the switch may resolve it.

  • Yeah it's a Samsung Issue, but the switcher is out of the TV, not the in TV like samsung.

  • The 3.0.0 patch was supposed to address this. So far, it hasn't swtiched on me as far as I could tell. And it's not a TV problem, it's the Nintendo Switch and it's bad implementation of the HDMI-CEC spec. I use an external HDMI switcher and before, the Nintendo Switch would occasionally switch if I'm using a different device. Jun 23, 2017 at 18:50
  • Ah ok I haven't jumped to 3.0.0 yet, I'll try and see.

  • This jumped back at the top of my list. Can still confirm. An update solved the problem.
