Thank you gentlemen so much for taking the time to help this neophite! I did not know that the processor could interrupt the transmission of the 3D signal. That would have made me opt for a 2D set, since the store I was at had both versions of their 70" on a 33% sale -- there was little time to choose just then, as the one and only 70" 2D set they had, had another buyer standing right there waiting for me to decide. I went for the 3D not only because of the 3D, but because of the double refresh rate and maybe other features I did not have time right then to check out. Didn't really know if I might or might not like 3D -- never seen the new 3D on any screen, large or small!
Bottom line, love the TV -- in fact changed my whole house around to accomodate it after feeling the love, but still had no 3D movie to test that aspect, even just to know it worked. Then came the movie in the mail, then came the problems. Last night I shortened my HDMI connection with my Monoprice cable -- had a 6 footer versus the earlier experimented with 20 footer which did not work. And guess what? -- I got 3D! It went out a few times and back to flat, but after those glitches, performed for 15 minutes or so, enough to assure me the feature worked, which was what I wanted to know for the immediate goal.
Was not considering a new processor, and don't know if I am now -- feels like I got pulled into something -- but what I did want to know is if there was another way to go about it -- can you use an HDMI splitter, or do they even make them? -- one path for the monitor TV, the other for my audio processing? How about blu-ray players with two outputs for HDMI? -- do they make those/would that work?
BTW, Monoprice makes some great, nice cables -- this company blows me away, so it was hard for me to believe that their cables would not work for 3D, whether they were sold as "high speed" or not. And again, I really appreciate that folks would take time out to smooth out this somewhat rough startup for my entry into 3D -- maybe it will become my whole new thing!
