I just picked up an Oppo 103, and am curious what the latest thinking is about using HDMI 1 vs. 2 for the input into a Lumagen Radiance Mini.
I had originally planned to have the Oppo's HDMI 1 as input into the Lumagen, and HDMI 2 as input into a Sherwood R-972 I'm using as a dedicated DRC box as part of an experiment to check out Trinnov, with Split A/V mode. My thinking is that I would, with the independent resolution/processing, get the full benefit of a high-resolution video directly to the Radiance Mini, and let the R-972 only do audio processing with Trinnov (video bypass mode on, to avoid noted unpleasantries with the Sherwood, and at any rate the HDMI video output isn't being used as the Sherwood's sending audio on analog pre-out). Since the two HDMI outputs from the Oppo are effectively independent in this case, I'd be good and minimize problems AFAIK.
OTOH, I read through the Oppo 103 thread, and apparently there's some opinion as of earlier this year that the Oppo's HDMI 1, with mandatory DNR enabled, will somehow produce a less than optimal scaling, VP & calibration even with Source Direct mode. Thus, using HDMI 2 directly into the Lumagen is recommended by at least one user to avoid any picture softness/sharpness issues or artifacts from DNR being passed to the Mini. The problem, though, is that then I have to have both HDMI 1 AND 2 on Dual Display. This results in the 'best effort' resolution for both outputs. However, 'best effort resolution' opens me up to some other issues with the Sherwood (e.g. codec delays and possibly passthrough problems with my Region 2 PAL, as the Sherwood doesn't have a PAL scaler and I don't see any evidence that any R-972 users have successfully passed PAL). I have close to 100 foreign-language PAL DVDs (movie and concert discs), so this is an issue for me.
As the two HDMI outputs would now be working on the same output resolution, I might create problems that I wouldn't have with the Oppo's HDMI 1 as the input into the Lumagen. And who knows what would happen to my MC audio....although when I do source direct from the Oppo to my Denon as a test of PAL DVDs, I get proper MC audio but not video on Source Direct and no video scaling on the Denon. It's unknown if 'passthrough/bypass' really means the same thing on different AVRs.
Right now my Lumagen sends on HDMI out to a Darblet and the VT50, from other sources connected to my existing Denon 4311 on one of the two HDMI inputs, so with this unit I only have a single HDMI input free for the new Oppo 103 & the Sherwood. And with the Darblet, I'd prefer not to reverse any part of the display chain because it works well as things stand.
Am I worrying about nothing, or is the practical difference between Lumagen processing of HDMI 1 vs. 2 relatively trivial in practice except to the most critical calibrators? I think I'd make my life easier with HDMI 1 with Split A/V feeding the Lumagen, honestly, so I'd prefer to go that route if the practical difference is low, or can be compensated with using the Lumagen controls. BTW I have a 55" Panny VT50, BTW.
Any thoughts about this HDMI connection issue? I originally wrote this up as a question on the R-972 thread, but I think this is a more appropriate place to get opinions from dual Oppo/Lumagen users.
