My setup is a DirecTV HR24 and a new Apple TV as sources; a Yamaha RX-A880 as AVR, and an LG 65UN7300PUF.

I'm trying to work out the most efficient way to keep the Deep Color problem from occurring. The problem is that using the Apple TV under some circumstances brings up a message on the TV and kills the audio on the AVR.

We've figured out that if we pick up the TV remote (I mention that because we don't need it for any other thing), navigate to the Deep Color choice in the TV menu, and turn it off.

We accidentally found that if we wake up the Apple TV, then about a minute later we switch to the Apple TV input, there is no message and the TV does not switch to Deep Color.

I have not had the time to sit in front of the TV and wait for things to time out over and over to determine exactly what's necessary, you know, thirty seconds, forty seconds, switch to some other input for a while, or... who knows?

Do you know? Do you have the potential for the Deep Color problem but you've got specific steps to avoid it? Does it vary from setup to setup?

Thanks.

To avoid problems with deep color, turn it off in the AVR menu.

Thanks. Makes sense.

The manual has five references to Deep Color. Four of them are in a paragraph explaining Deep Color and the fifth one is in the specs where Deep Color is mentioned as a feature of HDMI. There is nothing in the manual about adjusting it or turning it off or on.

And, it being the middle of the night, I can't quite reach into my memory to find the URL I can use to make adjustments on the AVR... maybe it's there.

I'm puzzled that one might make an AVR adjustment to turn Deep Color off, since Deep Color is a feature of the TV and it is turned on and off via the TV's menu. But hey -- you got the steps, I'll dance 'em!

Have you tried adjusting Monitor Check and 4k Mode? p153:

If you want to access the AVR's menu, find its IP address, type it in the address bar as 192.168.x.x/setup (or, use whatever an Apple router wants, if you use one)

At least it can e turned off- imagine having this problem and not being able to do anything about it.

Just another reason to hate HDMI.

How do you work out what the video setting should be, since I'm not having a video problem, that will allow the audio to come out of the AVR? Is it hunt and peck?

Wait -- I did that and don't find either Monitor Check or 4K mode. At least I don't recognize them if they are there.


Yessir.

While we're at it, what do you suppose is the adjustment that will allow MUTE to stay as set when changing inputs? I don't want sound immediately upon change of input. I want it when I turn off MUTE.

The choice might be there, but I find On, Off, and On/Off... so is it one of those?


Yamaha should not have called remote control menu "Menu" while calling the network approach "Menu."

Thanks for your help.

You have 4 scenarios. Try them all
on / mode 1
on / mode 2
off / mode 1
off / mode 2

Newbies...

That makes sense since there are not any instructions. Remember those? Instructions, I mean?

How can there be instructions when manufacturers aren't even sure how their stuff will work with other products?

The more we go on, the more it seems like "the instructions" are devolving into the kind of "documentation" that used to be gathered over the campfire at night... back before we had houses and stuff.


Edit:
This is out of control and the only reason it's near acceptable is there's only two variables, on/off and mode 1/mode 2.

If there were one additional variable, there would be eight scenarios. If four variables, sixteen scenarios. Et cetera in powers of two.

Try moving to 4:2:0 (I think) for Apple video or try using a Roku.

What HDMI cables are you using. Are they 18g or super high speed yada yada? You don't mention...

Edit: after doing all this, the system threw me a new curve. Some time after I finished the stuff below and switched back to my DirecTV receiver, the Apple TV went to sleep and the TV turned off.

Gotta love that HDMI.


Following up on your previous post, I went further into the Apple TV settings than I had. Here's what I found:

It was set at Enable HDR, Format 4K SDR, HDMI Output YCbCr, and Chroma 4:2:0. Match Dynamic Range and Match Frame Rate are off.
There's a Check HDMI Connection routine that says the HDMI connection is good. A box lists 4K HDR 60Hz and 50Hz as unverified formats.

Perhaps not surprisingly, I found a flaw in the TV. There's a full gray screen during the HDMI Connection test, and on this 65" TV, a square about inches some 6" from the left edge, vertically centered, is obviously darker than the entire rest of the screen. Looks like it's time for TV service.
