Hi
We are a software developer, directtv.com.au. We need to connect a single PC or embedded system to two side by side displays, where the video extends across both displays.
Although Windows automatically supports extended monitor mode for windows from simple aps like Word etc, it does not work propery with Media Player and in particular our software.
We think we might try using IEGD to make a custom video config file but we are not sure whether this will work
Has anyone done anything similar to the above?

ComputerPaul,
Extending video (by this I mean things like movies) across two displays will be problematic. The display is part of the pipeline for the media player. If you limit the multiple display option to just one adapter (for example, dual display from a single part) that will eliminate some of the problem. You would also have to figure out how to handle things like overlay of which there is generally only one, and therefore would only work on one of the displays. Protected content would have a hard time with this as well. In general, I don't believe this is something that Windows software can actually do. If you're using a custom-built media-player, didn't use DXVA,and just used the CPU for decode and playback I think you could get it to function, mostly, with a lot of work...

We're looking into this for you. We're not sure whether or not this is still supported.
