This is actually extremely common and usually involves a problem with HDMI cabling and signal timing. My SC-77 was very sensitive to this. Things that screw up signal timing in HDMI/HDCP:

1) It can be as simple as your HDMI plugs are not properly seated in the jacks.

2) Too many connectors! The optimal HDMI connection has two and only two connectors - one at the input and one at the output - with one stretch of cable between them. Signal wire fan-out or fan-in, which is done for every connector in the path, alters timing in subtle ways. HDMI/HDCP timing is SO sensitive that these very small variations can mess things up. In practice this means that the following items should be avoided wherever possible (yes, sometimes they cannot): L-Adapters, coupling connectors, F-M extension cables, wall jacks.

3) Long cables. HDMI/HDCP timing is so tight that the longer a cable gets, the more likely that you will have problems.

4) Out-of-spec cables. Cables certified for HDMI 1.2 may or may not work in your rig for HDMI 1.3.

That does not mean that any of these items guarantee problems - but they do make them more likely. Combine them and problems become MUCH more likely.

Anecdote: I have a 30' run from AVR output to TV (wall mounted). When I first put it in, it went output to wall jack (6' cable), wall jack to wall jack (20' cable), wall jack to L adapter (3' cable), and the L-adapter to TV input. Yeah - the wall jacks looked really pretty and professional when they were not being used. This is not all that uncommon a configuration. It worked intermittently and failed intermittently. On a tip here, I tested a new cable (same manufacturer and model other than the length) that was long enough (30') to fish through the wall and come out an opening in each of the wall plates at both ends (rather than using the jacks and then using 2 more cables). The cable was about 10' longer than the "in-wall" cable had been and the overall run length was 1' longer. I still needed the L adapter on the TV end, but I went to 3 connectors/adapters/couplers from - count them - 9. All the blank screen and audio dropout issues disappeared.

We have had people here who had 1.5' HDMI cables that just did not work, so they went to 6' cables for the same connection and everything worked great from then on. The HDCP timing on the chipsets in their equipment was just too sensitive and could not adjust to the short cable length. Yes - you read that right - the cable was too SHORT. High quality, spec-certified, 6' - 12' cables seem to be some kind of optimum. That does not mean that longer or shorter cables won't work. Again, it is all about risk. These other cables will work fine in some rigs (I have a 30' cable and things are fine) and may not in others.

If I wanted to do it over again (which I don't) I would go get a 30' cable with Redmere compensation technology. The Redmere stuff seems to be pretty solid for long cable runs, since it is an active cable that has circuitry/design that compensates for its own length. Basically, every Redmere cable out there, no matter its length, LOOKS like a normal 6'-12' cable as far as the connected equipment can tell. I helped a buddy run a 50' Redmere cable from his PC to his bonus room AVR and it works like a champ. Again though - we also bypassed anything resembling a wall jack ;-)

I had an HDMI cable tht went from rec. output, 30' to a wall jack, then 1.5' from wall jack to projector. Looked great... but it didnt work. I simply removed the center part of the wall jack and pulled the 30' hdmi cable through the wall jack and into the projector, and it worked fin. Yes, those wall jacks look great, but dont seem to work well

Question SC-77/79 Owner's Disc

There was one posting in this thread of the owner's disc for an SC-75, and I have downloaded it. (Thank You JoshG). It isn't for the 77/79 (I own the SC-77, but never received the disc with my unit.) Didn't know there even was a disc until long after my purchase. I have been searching online and at all the Pioneer sites I can find, with no luck.
Would anyone here be willing to help out those of us who got shortchanged and upload a copy of their disc for the SC-77/79?? Dropbox is what JoshG used, and it worked fine. (I understand the same disc is used for both models) Or point out where I can download one, or any other method you prefer that will allow those of us without, to download our own copy.

I'm using the SC-LX78.

Does the LX-Series have all no special settings for Dolby Atmos?
I found so far only settings for the Atmos speakers themselves.
I expected to have settings how deep and with which angels Dolby
Atmos should individual work. Is this unusual to make their
personal settings?

I'm surprised having also no settings for the Dolby Atmos Upmix.
Here I expected to influence, what and how should be upmixed.

I think you're in the wrong thread. I believe the SC-LX58/78/88 are the equivalent of the Elite SC-85/87/89. The SC-75/77/79 are pre- Dolby Atmos.
