First, to be clear, in my second post, I meant assuming I give up the "passive" solution and try for an active only.
Your only choices without a new card are to either find an HDMI option (such as CEC) that *may* be preventing proper handshaking or to hope ...
I just did a search, and CEC is the protocol that allows remotes to turn on or off other devices? I'll check, but I'm pretty sure that is already disabled in my Denon. I don't think the Optoma supports it, but I'll check on that also.
one of the two companies changes their interface sufficiently for the other to recognize them.
I'm thinking that is probably my only hope, and I have nearly none.
Also make sure you are outputting a video format that exactly matches what the Denon is expecting (including resolution and frame rates).
Since the hd4000 driver will not even acknowledge the existence of my Denon, I don't know if that will help, but 1920x1080p is supported by all, and that is what I was trying to use. Also 1920x1080i (which is what Optoma advertises best), but still no go.
Also keep in mind that audio and video are always sent. There is no such thing as a switcher saying whether audio should be sent.
Yes, I was aware of that.
When EDID handshaking fails, nothing gets sent or what is sent isn't compatible.
And unfortunately that is what I expect will happen if I put in an active splitter. I was hoping someone more knowledgeable than myself would tell me I was wrong and that an active splitter would solve all my problems.
I'll send some whiney messages to Gigabyte, who makes my MB to tell them I want it to work with my receiver, but I expect no changes in anyones policy. I have resigned myself to putting in a separate video card, or running 6 analog audio signals to my amp. I'd rather the amp did the D/A since the converters are better, but I think this is my only solution unless I want to buy yet another video card. I have at least 3 still hanging around doing nothing. I know one will work (gt240) but it uses 20-30 watts extra, and it ticks me off that I have to waste it just because Intel or Denon or both appear to be acting like children who can't get along.
