Denon AVR-X520BT Unstable on 4k

I wondered if anyone could shed any light on the above problem.  If I have either of the 2160 outputs enabled on my V6 box, then the result on the Denon AVR is very unstable (with a 4k source of course). 

Picture freezes, cuts out, flickers, pixelates, states "Not HDCP 2 compliant" and other similar glitches every few minutes. Bypassing the Denon and going straight into the TV is fine, so it's not the V6 box.

I know the 520 is quite old, but other than replacing it, has anyone got any suggestions?  I'm using the Cbl/Sat input.

Cheers,
Tony

Re: Denon AVR-X520BT Unstable on 4k

Hi Tony, 

Looking at the specs for the avreceiver/avrx520bt  it is HDCP 2.2 compliant. 

That would mean you need a HDCP compliant HDMI cable.

If you are using a splitter then that may cause issues as well as the splitter each connected component would need to be HDCP 2.2 compliant - please see

https://www.virginmedia.com/help/virgin-tv-watching-4k-ultra-hd-content  for more information.

From the above link for your equipment, " 4K Ultra HD/60 Hz Video Pass-through; HDCP 2.2

Equipped with 5 HDMI inputs, the AVR-X520BT features support for 4K Ultra HD full frame rate 60 Hz pass-through on 3 inputs along with 4:4:4 Pure Color sub-sampling pass-through, along with 3D compatibility on all HDMI inputs. It’s also equipped with HDCP 2.2 signal handling, a requirement for 4K Ultra HD copy-protected content."

Re: Denon AVR-X520BT Unstable on 4k

Hi Dave,

Yep, the HDMI cable is a brand new Virgin HDCP compliant one and the specs of the receiver state that it should be ok... but it ain't.

I guess I could try another input on the Denon just in case there's an issue with just the one input but somehow I doubt it.

Unfortunately, I don't have any other 4k source to try but as I wrote in the OP, it works fine direct to the TV, so I doubt it's the V6 box.

Those errors that I described don't all happen at once, that's just a selection of the various errors that I get every few minutes if I try to watch 4k.
