    Does anyone know how to force a Radeon 9800/WinXP to output via DVI, even when WinXP thinks there is no device connected, and there is nothing connected to the analogue VGA?

    Thanks,

    Colin

    Don't think it can be done. I'm assuming you had something connected to the DVI but not switched on, so it wasn't recognised at boot time ? I have problems with that - I'll often boot the pc with a projector connected to the PC but not switched on - so it doesn't recognise there as being a device connected, and can't force detection.

    I suspect it's a safety feature - you're not supposed to 'hot-plug' dvi connections (i.e. both devices should be off, and not grounded when you make the connection). Having fritzed one graphics card by not following those guidelines, I can see where they're coming from. But the blue sparks you get when you do it are pretty ;)

    I'm actually trying to connect the DVI out to my scaler (for pass through). As the scaler is a dumb device, WinXP/ATI conveniently decide that there is no device connected so shuts off the DVI output. Apparently, you can force the DVI output on the NVidia cards - was wondering if there's a workaround for the Radeons?

    Might be a problem with your PM box, as I've replied 3 times to your last PM.
