Hey all, just wondering where to start looking for information on how to create an app that will switch between dual view and horizontal span. I want to use C++ to write this app and i have a nVidia graphics card. i've managed to find information on changing screen resolution, but am unsure if this is all i need to be able to do this? Any ideas? and thx in advance for the help.

Hey NovaCaine,

I don't know exactly what you are talking about - but my understanding is you want a split view like in NFS3. If that is true, you could try dividing the viewport into 2 equal rectangles and fill the rectangles separately, and then flip buffers or whatever you do for a single view.

I could offer code depending on what API you use for graphics - SDL?

Cheerio

Hey deavik,

i want to access the driver to change the setting between dualview and horizontal span in windows. it's for a company i'm working for, they have some demos that need to run in dualview( the demo picks up the second monitor) and horizontal span. its not coding a DX app with different viewports, its telling the driver to change its setting, or something like that.

sorry if I'm telling you what you already know, but if you have a nVidia card go

Control Panel->Display->Settings->Advanced->nVidia tab->nView Display Settings.

there you can change the display mode. I'm wanting to switch between them, using default settings if need be. I know ATI have something similar, but i'm creating a windows app to only be used on nVidia cards.

Just wondering if anyone knows of any way of doing something like this?
