Denon avr2300 rear HDMI issue

BENJIspendlove

Hi folks,

Since getting the new benq w2700 4k projector from yourselves I've moved around some stuff and got the samsung k8500 4k player connected to the denon avr2300(from yourselves) now. However I can't get any picture when the 4k player is connected to the back of the AVR. I've tried multiple combinations of setting things to 1080p or 4k, and hdr on/off but to no avail.

I CAN get picture from the (4k player > front hdmi on Denon AVR > 4k projector )

I CANNOT get picture from (4k player > back hdmi > 4k projector ), i've tried multiple rear hdmi ports ( all supposed to be hdcp2.2) and also even removed all other hdmi connections, leaving only the 4k player.

I was thinking it may be a cable issue, but it wouldn't explain the difference in front and back panel hdmi using the same cable.

Both of the above situations are using a standard 2m HDMI cable from amazon to connect the 4k to the amp, and a 10m cable of the same quality to connect the amp to the 4k projector.

And finally, to add to the odd scenario, I get picture from the 2m cable director from the 4k player to the projector, but NO picture from the 10m cable going 4k player to projector. (yet this cable works if the amp is in the chain and the front hdmi is used)

I've ordered a new higher quality, 7.5m cable to re-test, but this still doesn't explain the rear HDMI issue.

Just wondering if you have any ideas or thoughts on the issue or is it a fault?

TLDR

Hi Ben.

Sorry to hear you are having some issues.

If you have a different source other than the 4K play connected to the rear HDMI's do you get a picture?
Do you know the brand of the HDMI cables and I can check them out to ensure they are 4K rated? If all cables are not 4K then you will get issues displaying the picture.

How long have you had your current HDMI cables?

Which HDMI out are you using for the projector - Monitor 1 or Monitor 2?

Is the 2300 on the most current fireware version?

If you skip the 2300 and go straight into the projector does it display the resolution as 4K on the projector or just 1080P?

Are you sure that when connected to the front HDMI it is displaying a 4K resolution and not just 1080P?

I have double checked and all HDMI ports should be 4K compatible so the port should not be an issue.

Denon comes with a 2 year warranty so if you PM your details i can check if its still inside it in-case it turns out to be faulty.

It does sound a little like the cables you are using are not certified 4K but let me know on some of the above and we will see what we can come up with.

Hi Kenny,


Cheers for the prompt response, I'll do my best to answer you questions


If you have a different source other than the 4K play connected to the rear HDMI's do you get a picture?
I have an Nvidia Shield which works at 4k, but this made me wonder was is a 4:4:4 hdr colour issue?

Do you know the brand of the HDMI cables and I can check them out to ensure they are 4K rated? If all cables are not 4K then you will get issues displaying the picture.

How long have you had your current HDMI cables?
The 10m has been used since i got the w1070, so 5 years at this stage the other 2m cable i'm not sure about.

Which HDMI out are you using for the projector - Monitor 1 or Monitor 2?
Monitor 1 out of the Denon, the main one

Is the 2300 on the most current fireware version?
Newest firmware on the 4k bluray, projector and the AVR

If you skip the 2300 and go straight into the projector does it display the resolution as 4K on the projector or just 1080P?
I'm fairly certain it was 4k, however i didn't double check that, it auto'd and worked.

Are you sure that when connected to the front HDMI it is displaying a 4K resolution and not just 1080P?
I'll double check this as well, I think the projector said 4k. I don't have any sources set up differently that others

I have double checked and all HDMI ports should be 4K compatible so the port should not be an issue.
Yeh i went double checking that as well, wasn't sure if the HDCP was assignable to 1 port, which is why I unplugged everything for a test.

Denon comes with a 2 year warranty so if you PM your details i can check if its still inside it in-case it turns out to be faulty.
I bought it from yourselves on 30-November-2016, so its just outside the 2years now.

It does sound a little like the cables you are using are not certified 4K but let me know on some of the above and we will see what we can come up with.

I've gotten a new 7.5m cable on me now, will test this later on,

Cheers for coming back to me Ben.

I would be fairly confident to say the 10 meter cable is non 4K and is causing the issue, 4K was not on the market 5 years ago unfortunately which would make the cable only capable of 1080P.

Even to get HDR to display, if all cables are not HDR compatible it will not display. 

Once you get home and try out the 7.5m one let me know your findings and we can take it from there.
