OK! I think I have an answer to your problem. While I was putting up projectors at work, I noticed that they had a similar connector to the one you described. With rows of 10 instead of 8 and funky angled connector. I asked my co-worker if he knew what it was and he said that it is a specially designed connector that carries USB as well as video. (He said he thought it was called M1 but wasn't sure.) But he quickly pointed out that the cables are expensive and custom made (noting that I was carelessly whipping around the cables). So this might be the answer to your problem.
