Query: Doesn't work.

When I first received the splitter, I briefly tried it with my Apple Cinema Display with the MacBook Pro, It worked. I recently bought a ViewSonic display to see how well it work with the splitter. It didn't work at all, although directly connecting the ViewSonic cable worked. Not only that, it no longer worked with just the Cinema display. Nada, nothing. The computer detects the displays, but neither will display a raster scan when connected through the splitter, whether individually or in combination. Each works when individually connected directly. So this item is a loser. Guess I'm the loser. :-(
