Default Re: Mplayer, vpdau, and 3 displays with edge blending.

OK. So I was a little confused about the details and have cleared a few things up. The edge blending for us is done in hardware an a separate machine. It would be nice to have this in the Nvidia driver, but not required.

What is necessary is the ability to pass overlapped regions to the different displays so the edge blending can be done. In other words display 1 handles horizontal range of 0-100, display 2 handles 90-190, and display 3 handles 180-280. From my understanding twinview does not allow this, all the displays must be unique, and we are limited to two.

Apparently xinerama allows for this and that is why we use it. So we either need the quadro plex to handle the edge blending (which means it is sending overlapping content to each display before creating one large display) or allow for xinerama.
