I am using Premium Certified Cables (have also tried amazon basic hdmi cables), 3m (10') to the display and 2m (6.75'). I am also on my second receiver which is doing the same thing.
My sources are:
HTPC (Nvidia GTX 1050Ti) - No Issues
PS4 - Blinking @ 1080p HDR
Tivo V6 - Blinking @ 2160p\1080p
When I use my PS4 for HDR gaming at 1080p I get random blinking ie a black screen for a split second, it is fine for non HDR gaming. The same happens if I set my Tivo box to output at 2160p.
If I connect either the Tivo or PS4 directly to my display I do not see any of these issues and the only time I see this problem is when I introduce the Marantz Receiver into the equation. I am using bypass in the receiver so no scaling is occurring and I have enabled the 4K option for HDMI on the receiver.
I can use my HTPC to play 4k HDR movies with no issues at all so all I can presume is that this issue is a Handshake issue or a compatibility issues between my Sony display, Marantz and (PS4/Tivo). I also have a friend with the exact same display and receiver setup who is experiencing the same issues.
I have contacted Marantz and followed all the advice they have given and nothing has solved the issue. I have also googled about and see that Denon and Marantz have issues with the PS4 and Xbox.
Is anyone out there running a PS4 in HDR or a PS4 Pro with a current gen Marantz or Denon and if so are you getting issues or have you come across this and solved it?
If the Marantz is a no go which is looking more and more likely I am thinking of going for a Yamaha RXA 2070 instead, however I just wanted to make sure this would solve my problems.
Any help would be much appreciated.
After I read your post on AVR it reminded me of an article I read about how HDMI (ACTUALLY HDCP) FOR "HEAVY DUTY CONSUMER POLICE" lol Anyway, here is the jist of the situation:
the HDCP was invented to keep people from copying copywrited material. I get that.
All newer audio video devices are required to be HDCP compliant as of a certain date.(They do not all have any way to update their firmware!)
How it works- Each device has a hidden code that it sends to the next unit that is turned on to the HDMI "bus". Each unit talks to the next one and they have a look up table in their firmware) to see if the next unit qualifies as something that is legal to communicate with.
If they like each other, then they come up with a 3rd secret handshake number that they share as long as they are still hooked together and talking. every few seconds the secret number is re-verified, and if there is no agreement on what that number is, then one or both will stop communication. (black screen)
Now here is the hard part- the oldest unit in the system will not have a current look up table that shows that new unit you just introduced into the system- especially if it does not have an internet connection available to update it's "firmware".
So it will not be able to look up your new SR8008 or whatever, and the firmware in the SR8008 will not have a match for that old DVD player that was built without an internet cable socket.
So they will not be able to reliably (or not at all) communicate.
Now your TV might be "on the list" because it is internet savy and is fairly recent, and it may not even be all that particular about which DVD player it is talking to, but when you introduce a 3rd device into the "handshake" it too will have to play ball with the other two, and most likely it will have to accept both of the other individuals on their own merits and decide if it wants to hookup or not.Or mabey it will talk to one and not the other!
It would be almost like doing a LAN connection between computers. If you don't have the passwords you can't get on the network!
Or am I over simplifying things???
All of this because of the HDCP rules for engagement. Not sure how the third CPU coming online is supposed to jump in??? Possibly it will have to check its' firmware for a match again, but no idea how this would take place. Especially if all 3 devices were turned on at the same time or out of sequence.
So what could possibly go wrong with this scenario?
Another nightmarish scenario - Your system is working fine and the oldest components are still talking to the newest ones, but there is a spread of 3 or 4 years between the oldest and the newest one. You only updated your firmware when you hooked up your latest component that needed it in order to talk to the others and everyone was happy at that time. But who knows how many years of product the new firmware update will be applicable to? 2010 to 2019? or just 2016 to 2019. If your oldest unit is outside that range you may have a problem.
Now it's next year, and you decide to upgrade that 3 year old receiver. Your new toy arrives with "new firmware updates available" maybe some bug fixes and other enhancements that sound like they are "must haves" So you download them all and suddenly your system quits working. Hmmmmmmmmmmmm?
Well one possibility is that the latest firmware did not contain the liscensing code for your oldest HDMI compatible unit any longer????Or it may only contain firmware for certain brands or certain models???
Some of your codes probably still work, but some of your oldest units credentials may have been omitted from the latest download data.
So you are now checking cables and buying new ones and sending in your equipment in boxes trying to figure out what happened.
The dealer says it works fine! It does work fine at his newer setup with all the latest updates and firmware with matching codes!( and matching brands)
He isn't going to have the exact same gear you have to test your unit against. So he can't re-produce your problem with the handshake.
It does handshake, just not to YOUR UNITS.
His tech may not realize what is going on???
But you get it back and it does the same thing again!
So you change brands! Well that might work if the "new brand has the widest and oldest firmware with the legacy data in it to cover your 4 year old XYZ widget.
I don' know if it is possible to get an older revision of the firmware and download that? Probably not.Or Brand specific firmware? Now that is just asking too much!
