Multi-display

Hey guys, I've got a multi display question here. It seems that I need a camera per display in order to render to each monitor. I'd like to render one camera view across multiple displays. How would I achieve something like this?

Example:

Some graphics cards lets you make a simulated display that spans all tree monitors. Then it should work direct.

 

Thanks for your reply. I was hoping to achieve this without having to fiddle around with graphic card settings.

 

You can render the image into one big rendertexture and the blit the result splittet into the different cameras that put it to the screen.

 

I'm not too familiar with Graphics.Blit(). After reading up on the documentation page, I think I might know what to do. If I have a three screen setup, would I create a fourth camera that would render the entire scene to a render texture, then use Graphics.Blit() to move that render texture onto 3 other render textures applied to quads that are each individually rendered by the other 3 cameras? Or is there an easier way that I'm missing?

 

I got it figured out, Graphics.Blit() was definitely the way to go!

I found a MonoBehaviour callback OnRenderImage(RenderTexture source, RenderTexture destination). I set up in my scene one main camera, and then one additional camera per display. Every camera that wasn't the main camera was set up to render nothing via the culling mask. I used the single main camera render to a source RenderTexture, then used that OnRenderImage callback on the other cameras in the scene and applied Graphics.Blit(source, dest, scale, offset) to show only a portion of the source RenderTexture relative to which display they were assigned to.
