Solution to HDMI @ 1080p receiver/display HDCP handshake problems - Page 2

When adding the HDMI switch - How are you guys setting it up?

RECEIVER OUT->HDMI SWITCH->TV
or multiple devices->HDMI siwtch->TV (bypassing the AVR)

the fix is not to use HDMI..... or if you must, run HDMI to TV and some other form of audio to receiver.

I have my RC-V667 setup in 5.1 mode so I just pass everything via optical or Coax to receiver.

HDMI is a pita and poorly thought out.

The fix is simple..
Require all HDMI products to be CERTIFIED...
Just like UL, Dolby, DTS....
Unfortunately the HDMI certification is not mandatory...
So many brands such as Samsung, Direct TV, Motorola, Scientific Atlanta, and Apple bypass this process and have multiple handshake issues especially when connected to an AVR with an HDMI repeater..

Just my $0.02...

all they had to do was stick with the DVI spec as it already was established, supports secure device connections, and adding audio bitstream was easy by using available pins on the connector.

I have a multimedia player connected to yamaha rx-v671, and then with hdmi out of yamaha, connect to a hdmi splitter (1x2),that goes to TV and projector.

Is there any special recommendation when powering on each device??

First splitter, then player and yamaha and last projector??

Last days I am having some black screens in projector that last seconds, and then continues ok.

Hello, just joined because I wanted to see if I could get some help with a very similar issue.

I recently ordered a triple play Time Warner bundle and got a Motorola DCX HD DVR for the living room. Considering I also have a PS3 I decided to get a 3-to-1 HDMI switch from amazon since my tv only has one HDMI port.

I can't post link to amazon due to 3 posts rule but it is the "Ultra High Performance HDMI Switcher, 3to1 Switch" by Portta.

I hooked everything up as follows (all using HDMI cables): DVR to switch input 1, PS3 to switch input 2, and switch output to tv. The switch does its job, it auto switches to the device it "sees" a voltage from. However I get about a split second of video and then black screen, I still get sound though.

After a while, repeated turning on-off it started working, I finally got video. Went away and then came back an hour later and once again I was getting no video and only audio. From everything I've read this has to be a handshake issue. So any insight into how to go about making it work would be really appreciated. ty

Reviewing the comments on Amazon shows that about 20% of buyers experience the same issue you are and end up going to another product. You could try changing out the cables as well as supplying power to the switch.

Switches and cable boxes have been a problem occasionally. However, there are a few things to try. First of all, set all devices (PS3 and Mot) to 1080i as a test. Also make sure that the Deep Color option on the PS3 is set to "Off". Deep Color provides no useful function at this time and eats-up HDMI bandwidth. You might also check your TV and the Mot for Deep Color and set those to "off", although I don't think the Mot has that option.

Now that you've lowered your HDMI bandwidth, test again and see if that works. If it works, then you might check the pedigree of your HDMI cables. One or more may not be up to the faster speeds.

If that doesn't work, it is probably an EDID handshake issue or just bit errors. I would not expect an HDCP problem to allow you a second of video and then no picture but still audio. HDCP is designed to allow nothing until the link is authenticated.

Also, for further trouble-shooting, there is an HDMI section of the AVSForum near the bottom of the forum lists.

Also - unplug all devices and allow them to renegotiate.

Hello all, thanks for your response thus far, I want to update as to what I've learned after working with a few setups.

So far the setup that gets almost everything right is by simply applying a separate 5V source to the switch itself so that the handshake/negotiation signal between devices stays active as opposed to the switch being powered via the device signal which eventually goes idle and thus the signal between them is lost.

I say this setup almost works because, after say more than a couple hours of non-use then when I first turn on the tv again and dvr I get nothing (no video + no audio). So I turn off the dvr and turn on the ps3 (which works fine) just to push a signal through so that either the tv is aware something is coming. So I then turn off the ps3 and turn back on the dvr, auto switches, and now everything is fine I get video+audio.

It's difficult to pinpoint what the exact duration of time is that the devices all idle and the signal is lost. Checking with one to one and half hour gaps everything was fine right when turned on. Anything past two hours and the signal is lost.

I don't really mind having to quickly turn on the ps3 and then dvr (when needed) to get tv service but it is a bit of an annoyance. So what do you guys think of this?

Sorry for the long post and I thank everyone again for your help.

I just got my new VSX-521-k and I've managed to get audio working if I run my htpc and xbox into the TV (LG Plasma) then the tv into the receiver by optical but I REALLY want to run the Xbox into the receiver via HDMI then the receiver into the TV but whenever I try the TV just doesn't get a signal. frown.gif can't figure it out, I've tried running it into different inputs on the receiver but it just seems like the receiver doesn't wanna sync with the TV... Any ideas?

Cheers,
Mitchilled
