We are banging our heads against the wall on this one.

CAT6 shielded from rack to 4 zones with Sony TVs.

Room 1: 100ft with receiver into Marantz sr6012. HDMI to Sony 75" 940e TV. Have extra cat 6 here, can run another extender from receiver to TV if long HDMI cable after receiver is problem.

Room 2: Exact same as room 1

Room 3: CAT6 straight to extender to Sony 49" 4k

Room 4: CAT6 straight to extender to 32" 1080p Sony.

Sources: 2 x Apple TV 4k and Luma surveillance

Matrix and receivers: Wyrestorm [Link: wyrestorm.com]

Brand new 4k 2.2 cables everywhere. And I don't even care if we get full 4k at this point.... 1080p would be fine.

All TV, receiver, and Apple TVs firmware up to date.

Problem: Can not get Apple Tv's to be reliable at all. Even if I drop res down to 720p. Even at closest display running straight extender to TV. Apple TV flickers constantly. Periodically it's stable long enough to navigate to Netflix or Hulu but when I play content I get a black or green screen with sound. We have successfully gotten through a few shows but nothing anywhere near reliable enough to turn over to client. Usually takes a few reboots of Apple devices works for a bit then a complete disaster again. And when it is working if you dare turn on a second TV the one that's already on, even if different source, flickers for a good 30 seconds then maybe get picture.

Doesn't matter if all displays on, or just one. Same issue regardless. I've tried multiple inputs, reterminating ends, etc. No luck. My next step is adding an Apple TV local at each TV but this adds some control system revisions I'd rather not play with.


Luma works fine at 1080p but obviously a different animal. Could this be an Apple issue trying to block distribution? They wouldn't know would they?

Doubt it though cause we are Using a similar set up but with the Control 4 matrix on another job and various displays and it works great. I did have to adjust the resolution to the lowest TV but that's to be expected.

Thoughts?

Problem is probably your 32Ē Sony if I️ had to guess. Did you try leaving that tv disconnected from the matrix & see if you get picture on all the other TVs?

If Iím not mistaken every TV has to be 4K capable for it to work properly. I️ could be wrong though. Had a bad experience once so now every Matrix Install every TV gets upgraded. Havenít had any issues since.
Knowing that Gold went up a few K makes me think "well now I have to do a better job on selling more equipment".

Yup, 32" sounds like the problem to me. Purchase a 4k Up/Down Scaler. Set the input for 4K and the output for 1080P.

Collect check and move on.

And what box would that be that costs less than a new 4k TV?

Are there 32" 4K televisions available? I have only seen computer monitors that support that resolution.

I had pretty much the exact issues you described with the same Wyrestorm box, spent about an hour with tech support and ended up swapping out the box. Project has been problem free for about 6 months.

*EDIT* Tech support told me that the skinny HDMI cables are problematic FYI. They had me change out the skinny proconnects I had in the rack with fat key digitals which seemed to improve the issue at the time of troubleshooting but did not resolve.

As mentioned issue is regardless of the 32 being connected or not. Also as mentioned we tried a lower resolution (as well as unplugging it) to test for the problem first two guys are commenting on and it didn't help.

these 4k sources have problems locking on 4k resolution with HDBaseT systems.

Try using one of these to help on the installation

1.1x2 HDMI splitter. The Binary B230 series is 4k compatible and seems to work well.
2.An EDID restorer such as the Ethereal HDM-AIO

It seems there are many EDID configurations available for that matrix. Which are you using? Have you tried changing the configuration?

Even with the 32" TV not on at runtime, it's possible it could still be mucking up the EDID if it is physically connected (or was physically connected when the matrix was being configured.)
If it's not simple, it's not sufficiently advanced.

yes. it seems the EDID gets through that the Display is capable of 4:4:4 60, but the HDBaseT wont actually pass that signal through so it confuses the hell out of the appleTV.

But even if I have the 32" plugged in and Apple tv set to 720p, same results.

AppleTV is defaulting to 4:4:4, this will be a problem for a lot of gear.

you plug the appleTV directly into the 32" and it doesnt work?

That should work fine.

As soon as the AppleTV Sees a 4:4:4 4k TV though, it freaks out. I ran into this last week in fact with a 5000ES Projector being fed by some standard 4:2:0 4k HDBaseT adapters. Even after I hooked the AppleTV up direct to a 1080p display and set it to 1080p only, when I went back to the HDBaseT, I got nothing. the EDID seems to override the manual setting in the AppleTV.

We're going back with a 4:4:4 Fiber kit in a couple weeks.

This sounds like a problem without a solution?

Apple is supposed to release an update to allow you to select 4:2:0 output.
