Did you try a fabric reset on the ATV4? There should be a small reset button on the back

Since you write about an ‘audio extractor’, I may suppose that your BV7-40 is a pre-MK3 version (without HDMI).

Orherweise why would you want to use an audio extractor?

Seems that there are some HDCP issues going on due to a not compatible extractor - you might need another/newer one.

However, first try another HDMI cable.......just in case.

Hi, and thanks for the quick replies!

 

Didn't find a reset button om the ATV 4k, but after reading extensively my suspicion lies in the audio extractor. The HDCP is probably not compatible with Apple's.

Tomorrow I will call the B&O center here in town. Hopefully they have an audio extractor with the right HDCP.

 

Kind regards,

Fabian

You need a rescaler. The BV7 can’t handle the output of the ATV.

So unlike the ATV4 HD, when using the 'MENU DOWN' function will the ATV4k not cycle through a resolution that is compatible with the BV7's accepted resolutions?  Might there be other ATV4k video options (eg disabling HDR) that can be switched off or reset to get it to work?

Given that the ATV was second hand, I think that I'd be testing it with a more modern non-B&O TV in the first instance, and then playing around with hdmi/DVI cables and audio extractors.

Furthermore I would be surprised if a B&O store will suggest a device that strips hdcp - it's not really in the spirit of the copyright protecting technology!  They'd be far more likely to try to sell you a newer TV.

As far as I know (https://www.howtogeek.com/721716/how-to-change-the-display-resolution-on-apple-tv/) the ATV 5th gen. supports 720p 50hz, which is the resolution the 3rd gen ATV produced and showed without problems. But getting to that resolution with "menu - down" didn't work at all. 

When I tried that with the 3rd gen. the white light started blinking, and new resolutions were shown. With the 5th gen. there is no reaction what so ever.

The local B&O shop referred me to another B&O shop in a bigger town. They specialize in older models as well and recommended me this one: https://www.kanex.com/hdmi-optical-audio 

 

The problem is that I don't have another TV at hand, so I think I have to try the adapter route...

Any thoughts on the suggested adapter?

I have used these successfully with ATV4 HD connected to BV6-26 and BC6-23, and they do remove the hdcp: 

Further thoughts/questions:

- Can you confirm the type number of your TV?  

- In the TV's 'connections' menu, under each input (AV1 thru 4) do you see an 'HDTV' sub-menu? If so, can you change it to show DVI-I? 

- How exactly were you connecting the ATV3 to your TV? hdmi to DVI-I?  And how did you connect the audio?

The type number of my BV7 is: 9361. A Mark2 if I understand correctly?

The ATV3 was connected via a hdmi --> DVI-I input and the audio came from the optical port, via a converter to the two jack connectors associated with the AV4 port.

In the connections menu the modus for AV4 is set to DVI-I.
