G965 + ivtv</TITLE> </HEAD> <BODY>  Hi! I have a weird idea, and I am not familiar enough with graphics hardware to decide whether it's possible or not. So, the question is the following: is it possible to use one graphics chip-set to generate image (ie. to render OpenGl, etc), and an other chip-set to output the image to a physical device? To be more specific, if I add a pvr-350 to my box, then I will have - the integrated 965G, which has abilities, but no working tv-out, and - the ivtv chip on the PVR card, which has a nice tv out, but no acceleration. I know that new cards can do all kinds of off-screen rendering, so it might not be impossible to use one chip-set to render the stuff, and then transfer the image to the frame-buffer of the other card. Is this physically possible? If yes, how can this be done? Do I have to write a special driver to "combine" the two devices, or can this be done from user-space? Kristof Csillag </BODY> </HTML>
