How to create widescreen map(one big map on 2 or more monitors)?
What kind of device is driving the displays? If it's a single PC, you could just drag the window to cover the entirety of two screens. Create your map (Network Atlas?) with your giant background image, then create the view with a single column of however many pixels it takes to span across the two screens.
Alternatively, you could slice your map background image in half, create two maps and two views, and have them in different windows.
I've been researching a videowall solution that will drive 16 or so screens in 2x2 arrays off of one server. The server pushes video to the displays over ethernet via a zero-client and it's all centrally controlled. This system will allow me to span a single piece of content across displays in a 2x2 format. If you're interested in the specific solution I'm planning on using feel free to send me a message.
As you can see, there's a few different ways to accomplish what you're asking. You would just need to give more specific details of what you're doing. Exactly which part are you having trouble with (creating the map, displaying the map in the web UI, showing the web page itself across two screens)?
