Smartboard 6000S resolution and connectivity

[Quatermass]

I think I know what the answer to this will be, but here goes! Is it possible - if necessary using some fiendish mix of connectors/boxes etc - to connect a Smartboard 6000S such that (a) it duplicates the attached PC screen (i.e. not as a second monitor) but (b) uses its own high resolution rather than whatever the PC monitor is displaying?
