I thought that was the normal setup for people like me with old receivers which don't support HDMI 1.4 and therefore won't pass through 3D, and is one of the reasons why the Oppo has two HDMI outs in the first place. So the player decodes the audio and sends it as LPCM via HDMI 2 to the receiver, while the video goes straight to the projector via HDMI 1. I thought when I'm playing it like that, there's no path from the receiver to the projector or anything else because everything else is powered off. I will try tonight by uncabling everything else from the receiver. If it's still an issue, I guess I would just have to use the analog outs on the Oppo for audio?
But again, all my video problems with HDMI 1 manifest equally well with or without HDMI 2 cabled in to Oppo.
I am using these Redmere cables
, 35' in length, without any daisy chains or wall sockets. The website rates these cables as Full 3D support, 4K2K support, 10.2 Gbit/s, etc. etc. but who knows. Most of it is in the open, but part of it runs in a casing along the wall with some other cables, and part of it is inside my false ceiling along with the projector's power cable, which is in a separate conduit. I will try connecting the projector to the player with the Hi-Speed cable that came with the Oppo.
Deep color is OFF on both HDMI's. Also, HDMI 1 is set to "video only".
I just finished with my first experiment towards diagnosing the intermittent signal loss from HDMI 1. To summarize, the Oppo-93 is directly connected to my projector via HDMI 1, while the HDMI 2 is connected to my receiver for audio. I get occasional mad flickering like in this video
, and at times the video signal is replaced by snow-only video. The later sometimes recovers on its own within a few seconds, but most of the times I have to pull the cable out of HDMI 1 and put it back in, and then all is fine till it happens again. Switching off and on everything completely in any order doesn't help. This happens typically 3-4 times while watching a single Blu-ray disc. Also, I have reproduced these issues without HDMI 2 being cabled in.
As an experiment, I just swapped the cables connecting HDMI 1 and 2. So HDMI 1 was connected to the receiver, and HDMI 2 was directly connected to the projector (with the same cable that HDMI 1 was earlier connected to the projector with). I also changed HDMI 1 to NOT be "video only" and set HDMI 2 to be the "Primary video" output. The latter caused HDMI 2 to send a 1080/60p signal to the projector as opposed to the 1080/50i signal it sent otherwise. I used disc 1 of BBC's Frozen Planet Blu-ray for experimentation, the same disc with which I had earlier got all kinds of signal loss and mad flickering issues when HDMI 1 was connected to the projector directly for video.
Under the new cabling arrangement, the video playback was absolutely fine. I did not get any flickering and the video signal did not drop even once. However, the audio signal, which now came out of HDMI 1, did go away twice, inexplicably. Powering down the Oppo or the receiver did not help, so I pulled the cable from HDMI 1 and put it back, and everything was fine immediately. FWIW, the Oppo, the projector and the receiver were the only three things powered on. There was no HDMI path to any other display or anything else. The Display button on Oppo's remote showed a data rate of 17 mbps - 40 mbps, the same that I had noticed when using HDMI 1 for video earlier. The audio signal was DTS HD MA 5.1 at 48K.
I shall next try sending 480p and 1080i signals via HDMI 1, as Bob had suggested
