I can confirm that the same thing has been happening with my 2016 4K Samsung TV.

I'll wrap up a session of Zelda, flip the TV to something else, and then 20 minutes later the TV will spontaneously flip back to the HDMI input being used by the Switch (despite the Switch being in rest mode and seemingly doing nothing at all), and then TV will then sporadically keep switching back to that input every few minutes until I either just entirely power down the Switch or remove it from its dock.

 

[whalleywhat]

To be fair, the OP is pretty clear in describing the topic: the Switch overrides whatever device is connected through HDMI and gets focus for itself, no matter what options are turned on. It's not that hard to grasp... if you bother to read the OP and not just assume people are whining for the sake of it.

To be fair, he really isn't. I thought he meant it was switching his controller or possibly had something to do with input lag at first. I don't think anything could make my tv switch its HDMI port externally, so some explanation is required for people without a similar setup. But yeah, that guy clearly just wanted to talk about whatever he was talking about.

 

[bennibop]

Having the same thing with my 2016 Samsung also. Didn't Nintendo add HDMI-CEC in the day 1 patch?


I also have the left joycon issues.

 

[airjoca]

You didn't look at the name of the product you're buying?

Should've been 1st reply.

 

[Chao]

My switch works perfectly fine with the CEC function so far, it's the PS4 (and pro) the ones I had to disable because it would turn on the TV or change inputs all the freaking time when I touched the avr remote. Then I would have to wait until it was fully turned on to go and turn it off again.

Do you have an avr? Maybe there's another setting you need to disable there.

 

[Mexen]

I've been in the middle of fights in SF5 on my PS4 Pro and it "switches".

Hah!

 

[kaydigi]

Does it with my ks8000 also. I will buy separate ac adapter and only dock it when I play on the tv set.

With the switch powered off and you dock it the switch powers back on. I wish it would stay powered off. Then you have to disconnect the joy cons just to selet the power off options again while docked.

 

[duckroll]

I changed the thread title because I feel this is a legit issue that needs more attention drawn to it, but I don't think we need to know about how it's specifically interrupting Street Fighter matches. That just confuses the issue.

 

[BeardyChan]

KS8000 here as well and this reared it's head ever since hooking up the switch. It screwed up my ARC CEC so badly I had to power cycle and reset multiple devices to get things back to normal.

 

[Joey Ravn]

To be fair, he really isn't. I thought he meant it was switching his controller or possibly had something to do with input lag at first. I don't think anything could make my tv switch its HDMI port externally, so some explanation is required for people without a similar setup. But yeah, that guy clearly just wanted to talk about whatever he was talking about.

Well, he did explicitly said that:

It takes an indeterminate amount of time for a docked, charging Nintendo Switch to take input away on my Samsung KS7000. I've been in the middle of fights in SF5 on my PS4 Pro and it "switches". I've been watching TV and it switches.

I thought that was pretty clear-cut. But, well, the title kinda muddled the issue. Now that it's been changed, it should be more straightforward.

Has anyone else tried my suggestion from the previous page? It worked fine for me, in what I've tested.

 

[MattKeil]

Mine does this, too, regardless of whether the "match TV setting" is on or off. While it's asleep it will randomly switch my HDMI switcher to the Switch input, then it'll jump back to the PS4 or whatever I'm playing (I suspect the jump back to the PS4 is my HDMI switcher realizing there's no signal on the new input). The only way I've found to stop it is to turn the Switch completely off with the power button on the unit itself, turn it on and let it idle, or undock it.

Really stupid.

 

[Soundslike]

I changed the options on my tv to not start when starting switch, didnt work.

what worked is that you need to turn the switch off and then on again.

 

[CrayToes]

UK KS7000 here. Having the exact same issue. I'm either having to leave it undocked or turned off completely.

 

[ZombAid82]

I've a similar issue with my 65B6D.
The switch is in sleep mode but when I watch something else, it always shows me that a signal was sent from the switch and turns off again after a half second.
The symbol for that HDMI output blinks on and off and is pretty annoying while watching porn, it always comes like a censor in the middle of the screen ;-)

 

[Skarnet]

Dock the Switch then hold the power button, that's the only way to do it afaik


Either you got lucky or were having a different problem. The issue isn't with the Switch turning on or off at unwanted times so that option won't do anything. In rest mode, the input changes over to the Switch input, the console stays off. It must be sending some sort of signal that the TV interprets as the device being on when it's not. There's no option to turn the auto-HDMI switch off, at least on the KS8000

Still that is a TV problem.. It works on most tv's and it is just crazy that samsung don't have the option to remove auto change input.. No problem with Blaupunkt, sony and phillips tv's I have tried so far..

 

[Smooth Operator]

Same issue with my Switch / Samsung TV.

It's connected to a HDMI splitter, and the splitter is also connected to my computer so i can use my tv as a screen if i want to. Every 10-15 min my computer screens turn black for a few seconds. It's annoying :/

 

[Jucksalbe]

Happens for me, too. Thankfully my TV doesn't support this automatic channel switching, so it only happens with an HDMI switch I'm using. Put it on a different HDMI slot on the TV and I'm fine for now, but that's just because my TV is old.
This problem really needs a fix in the next firmware update.

 

[RoadHazard]

Maybe not exactly the same issue, but I find it silly that even when I explicitly turn the Switch OFF (not sleep mode), then place it in the dock, it wakes up and switches input on my TV. If I have turned the unit OFF I obviously do not want that to happen. I want it to be OFF. It shouldn't even do this when in sleep mode IMO, it should only send an input switch signal to the TV if I dock it while it's turned on.

EDIT: Maybe this is the same issue, not sure. What I'm talking about happens as soon as I dock it, not some time later or whatever.

 

[CambriaRising]

Was playing Horizon earlier and this happened. Super annoying.

 

[extralite]

I haven't encountered this issue yet but I guess I will soon since I'm also using an HDMI switch box that automatically relays the most recently activated HDMI source. I had a similar issue with my Android microconsole which also randomly activated its HDMI output and my solution there was to turn off its power when I wasn't using it.

I can do the same for the Switch but I guess many people would prefer to charge their Switch while playing with another console, uninterruptedly. Hope they patch it soon.

 

[Mash83]

I have an LG TV and mine is doing this as well. It doesnt automatically change inputs but it pops up every so often with the option to change to the switch input. Would be way more annoying if it actually changed inputs.

 

[Skronk]

Hmm this might be why I've been having split second audio and video drop outs occasionally when using the PS4. Oh well I'm glad my TV isn't broken, I'll have to dig around in the Switch options and see if I can get it to stop.

 

[ClivePwned]

I had a weird issue when I first had the switch plugged into a HDMI switch unit. When I was watching something on Apple TV, the picture would go black for a sec, just long enough to make the apple TV pause playback. I took the switch out of the HDMI switcher and just plugged it into the second HDMI port on my TV that normally has the PS4 Pro input (with Zelda, PS4 Pro's not gonna get much use in my house for the next few weeks). Switch having its own HDMI has worked ok for me.

Hopefully the HDMI implementation will be fixed in a system update.

Not closely related but I do laugh when my Sony TV somehow knows when I'm using a PS4, Nintendo Switch or Apple TV (the onscreen display displays the name of the system next to the imput), but can't recognise the X1.

 

[spekkeh]

No problems on my Samsung Smart TV. (Not sure about the exact make)

Edit: no HDMI splitter. Seems to be happening with people with HDMI splitters?

 

[leng jai]

Happens to me on my 2010 Panasonic plasma as well.

 

[Hasney]

if one device connected to a tv does it and not the others, it's the devices fault

People in the other thread were complaining about not her consoles behaving strangely on newer Samsung's too.

 

[IlGialloMondadori]

Sony TV. Hasn't happened to me yet. Been playing since Friday. Must be doing something weird. Hope Nintendo will fix soon for those affected.

 

[Dagobert Duck]

Got a Samsung smart TV and didnt happen to me yet... weird

 

[Ninja Kn1ght]

Yeah, this happened to me too last night. I pulled out the Switch's HDMI for the moment.

 

[Tempy]

I have the issue with an LG TV.

I suspect the Switch intermittently increases power in Sleep Mode to check for updates, and inadvertently sends a signal over HDMI as well.

 

[Dali]

Still that is a TV problem.. It works on most tv's and it is just crazy that samsung don't have the option to remove auto change input.. No problem with Blaupunkt, sony and phillips tv's I have tried so far..

If I'm understanding what the problem is I'd put that on the tv as well. Id be pretty annoyed if my tv switched input every time I woke up my pc or roku by accident.

 

[NumberThree]

EDIT: Maybe this is the same issue, not sure. What I'm talking about happens as soon as I dock it, not some time later or whatever.

Here's how it works with my Sony TV:
- Docking the Switch with screen on -> TV changes input to Switch
- Docking the Switch in sleep mode -> TV doesn't change input

I'd bet the Switch doesn't send input change events at any other time, some TVs just consider any activity in the HDMI port as "this device wants attention". This isn't how HDMI-CEC works and that's also why turning those features off don't stop this behaviour.

 

[The_Spaniard]

Every once in a while my TV keeps asking me if I want to switch over to the HDMI port of my sleeping Switch. Luckily it's not forcing me over to it, but still a little annoying.

 

[Dunkley]

I'd bet the Switch doesn't send input change events at any other time, some TVs just consider any activity in the HDMI port as "this device wants attention"

That's what I figure too unless the HDMI-CEC feature is broken but even then I don't reckon it'd do anything while the unit is dormant.

Here's hoping it's a bug in the firmware rather than the dock requiring to shortly power the HDMI port every time it switches power state for some physical reason.

 

[Iamcorrupt]

I have an older samsung tv but my tv doesn't have auto switch abilities, my kinvio hdmi switcher on the other hand very much does popping in and out of the black screen from the switch nearly killed me mid stream tonight in fact whilst playing Dark souls. I think I'll be switching from the switcher for my switch.

 

[weekev]

There's no option to turn the auto-HDMI switch off, at least on the KS8000

This was the exact problem I was having, in sleep mode it was interupting the HDMI port. There is a setting which I changed in the system settings on the Switch and now I don't have the issue any more. Can someone else having the problem try it and see if it fixes it too?

 

[kami_sama]

I am receiving an HDMI Switch in the mail that supposedly, automatically changes when a device powers up. I hope this issue is resolved soon enough.

 

[Leemo]

Seems to work fine on my LG 4K tv - seems odd that it would affect some TVs and not others?

 

[CEJames]

I've been in the middle of fights in SF5 on my PS4 Pro and it "switches".

Hah!

"Bish, You WILL pay attention to me!" - Nintendo Switch.

 

[Calm Mind]

Switch don't like other switches? breh

 

[Impulsor]

It has happened to me while playing ps4. The effing thing just changes the channel to where my switch is connected, even when sleeping.

 

[Jolkien]

A Friend of mine has the same problem with his Switch and his Samsung KS8000. Disabled HDMI-CEC and the option in the Switch, still happens he just unplugged the dock from it's TV.

 

[Skronk]

I have an LG and while it doesn't change the channel it blacks out the picture and mutes the audio for a second. Which I've noticed sometimes happens when I turn the PS4 on.

 

[dancrane212]

Same thing happens with the Wii U in my setup. Had to dedicate one of my HDMI ports to the console to prevent it from happening.

 

[Lucifon]

I have the issue with an LG TV.

I suspect the Switch intermittently increases power in Sleep Mode to check for updates, and inadvertently sends a signal over HDMI as well.

I think this is it. The dock is effectively a dumb hub. So when the system wakes up so does the hdmi on the dock and the tv receives a signal albeit a blank one.

 

[Xadjim]

Maybe read more than the thread title next time?

Woops, I somehow mixed up a few threads I opened at the same time

 

[megashock5]

There's a setting on the Switch to change the power of the Switch to mirror the TV, it's meant to turn the TV on when you turn the Switch on. Turn it off and you are golden.

Nope. Turned it off on mine and it still did it. This is ridiculous.

It only does this when you're pressing buttons on the Switch. It's one of my favorite features.

Not here. Happens when I haven't touched it for several minutes or even hours. Just randomly while I'm trying watch tv.

 

[Smooth Operator]

It only does this when you're pressing buttons on the Switch. It's one of my favorite features.

You have at least 10 people in this thread telling you that it happens while they're doing something else.

Happened to me yesterday while i was watching a bluray on my computer.

looks like it might be fixable if Nintendo wants it

I'm actually not sure about sleep mode. I only know that docking the Switch while it's OFF makes it briefly wake up (why the hell this happens I do not know), causing my TV to switch to its input. And this is definitely a CEC thing, because devices I have that don't support it (original PS3 is one) do not make my TV switch inputs.
