Question Nvidia shield Onkyo tx-nr474 with optoma projector no image

Hi,

I've searched the forum and didn't found a solution.
I have a NVIDIA Shield connected to a Onkyo tx-nr474 and that receiver is connected to an optoma DH1010 projector but have no picture and sound.
The receivers notices a signal (surround gets activated) projector finds a signal (1080p) and then the projector goes back to searching and I see a blinking HDMI sign on the Onkyo.

When I connect the shield directly to the projector I get a picture and sound.
When I connect an other screen to the receiver I have sound and picture.
When I connect an other source to the receiver(Laptop) I get sound and picture on the projector.

So it only doesn't work in one specific combination. Is there something I can do about this?
I already tried to change some output settings on the shield but nothing helps.

I've tried different HDMI cables different inputs but nothing helps

1. Are you using the same HDMI cable and port for each of the tests above?

2. Have you tried setting the Shield to a nice easy output resolution to test?

3. Are you running the latest fw on AVR and Shield?

I was using the same cables for all my test and tried other cables too.
I've set the Shield to 1080p 60Hz 59Hz 50Hz and even 720p 60Hz but nothing
Shield is on latest (Oreo) and Onkyo had an update last week

Has it ever worked? I assume you've tried a different HDMI cable from the AVR as well?

Yes i've tried several cables. Yesterday I had image all of a sudden then I shutdown all my devices. When I retried it it didn't work anymore. When I reset the shield. I see the startup screen for a brief moment and then its back to on off again.

When I play audio on the shield it comes thru and then back off.

Are the cables HDCP 2.2 certified?

I will check later but it's strange that the same setup works with an external LCD screen or TV and not with the projecter(Using the same cables)

Do you have the AVR set to pass-through?

I have turned it off but still the same problem.
Pass-thru should be on, I just wanted to see if the AVR was adding anything to the video that was messing it up.

It sounds like a display resolution issue with the Shield and/or an hdcp 2.2 handshake problem.

Have you tried Shield Safe Mode?

Just tested it and in display safe mode it works.
It's display then. The AVR is doing something to the Shield signal OR just doesn't like it for whatever reason. Usually the cause is trying to display a res and/Or refresh rate it doesn't like.

The only difference I saw was that HDCP is turned of when going in to safe mode.
Is there anything I can do about this problem?

Have you tried setting the shield to 4:2:0 10bit or 8bit colour? If it's currently 12bit some receivers don't like that.
