Have a large home with Crestron DM. Late last year we did a massive system upgrade. All 4k I/O cards, RMCs, new displays etc.

Have a recurring video issue at one location that is driving me crazy.

Display (Samsung Frame) is fed distributed sources via DM to a Marantz SR8012.

For about a year or so everything worked flawlessly, including this location...until it didn't. If the location was powered off for any amount of time, no video on display.

Swapped the RMC with another one, recabled. No change. Would work until extended power down (say an hour or longer). Narrowed it down to a hot plug issue caused by having the AVR in the mix.

Bypassing the AVR, going direct to the Samsung media box along with programming DM to hold a video source when the location is powered off resolved it.

Made some changes recently. Client requested two local sources and wanted his OSD back so all got run through the AVR again. Programmer was confident his source hold command would keep things functional

System worked fine like that for a couple of days of testing. This morning he calls me, frustrated... Problem is back, no video on display... ARGH!!!

Been running into this issue a lot lately with ~1 year old Samsung displays, Marantz AVRs and any sort of extender or matrix in the mix (Snap, AV Pro Edge and now Crestron). Like Samsung pushed some sort of firmware that increased the sensitivity on this for some random reason.

I need to find a solution to this as it is driving me crazy.
HDMI.... The source of most of my grey hair since ~2010 or so....

What box do I need to throw into the mix to make this not happen? I did a lot of HDMI splitters on cable/sat boxes back in the day to resolve this.

It does sound like a Hot Plug Issue, from us the answer is the HDM-AIO2. If only that display if having the issue install the HDM-AIO2 between the Crestron Room box and the Display, then connect the green Phoenix plug on the AIO2 to a relay on the room box. Even time you shut off that display open the relay, when it is turned on close the relay as the last step in your macro.

Odd part about it is I lose both audio and video.

But if I unplug/reconnect the HDMI between the Marantz and the display, both return. I think the problem lies there rather then between the room box and the AVR.

Unfortunately for some reason Crestron omitted the relay outputs when they changed over to 4k RMCs. The previous ones had two relay outputs. I also think I am plum out of CatX cables between the family room and headend rack where the processor lives.

Just keep telling myself "if this was easy everybody would do it".

Looked at the HDM-AIO2 and that may very well be the solution moving forward. I noticed they are available retail but none of my distributors carry them. Worth trying to get signed up direct or?

To answer your questions:
Yes (IMHO) it is worth getting setup direct.
If you do not have an available relay, put the CS-IRKITCCUS [Link: metrahometheater.com] in the IR chain.
It is an IR connecting block with a built in IR code learning double throw relay.
I would also suggest the CS-IRCC cable [Link: metrahometheater.com] to go between the IR port on the room box and the IR input on the CS-IRKITCCUS.

Brent, does the AppleTV 4k introduce new issues not covered by the AIO?

Most of my issues have been with cable boxes thru AVRs but a have a new one with ATV and a new Integra AVR.  Old system used an outboard HDMI switch into an older Denon AVR and always worked. 1080p setup. Now it’s more 4k compatible stuff but older HDMI through the wall to the TV.  Are there AVR settings to check?

Seems I’ve read elsewhere the ATV gets dicey with HDR on and sometimes won’t display a picture.

Hi Brent,

Figured I would update this thread.

Unfortunately, the HDM-AIO2 did not work in this application. Every time it cycled, the tv would see the reconnected input as a novel source and bring up the two step "unknown source" followed by it syncing, followed by the "would you like to set up your Samsung remote to control this device" prompt. This was with every "smart" feature I could think of disabled on the display.

Wound up going back to bypassing the AVR, routing all video to the Frame media box and backing the audio out of the media box to the AVR. Works flawlessly save for the loss of the OSD from the AVR.

I guess that is just how we are going to have to do these from here on out to make the "smart" tvs stop trying to help and just play video.

"Every time it cycled, the tv would see the reconnected input as a novel source and bring up the two step "unknown source" followed by it syncing, followed by the "would you like to set up your Samsung remote to control this device" prompt. "

There is a way to disable this....

Interesting.
That is different then turning off "Anynet"/CEC in the settings menu?

Gonna have to remember that one...
Thanks.

If this really works well damn that's good to know.

yes... different from anynet/cec. It turns off the obnoxious and overbearing samsung auto configure/setup new hdmi BS...

Only problem is, you don't get any sort of confirmation that you've successfully turned the feature off/on. The only way to know if it works is to enter the keystrokes on the remote then trigger the HDMI auto sense (i.e. plug in an new HDMI source, or an HDMI source that is repeatedly problematic.)
