Something occurred to me last night.

Most Video cards have 3 extremely high quality 8-bit DACs in them. If it is possible to reconfigure the card to produce a constant stream of pixels without sync pulses, then it would make a perfect ultra-high-bandwidth audio card.

A resolution of 320x200x60hz has a pixel clock of about 3.8mhz, I think it would be possible to keep this fed with noise-shaped audio with modern CPUs.

What do you think? Has this been tried before?

Yes, it has - there was another thread with more info on that.... i dont remember its name anymore right now. However, there were some problems, mostly because 3d-chips have a much lower accuracy - and i think there also were some bandwidth problems...
