Monitor only works with agp not dvi

[Ilikepiedoyou]

I recently bough a Samsung 940bw monitor for my new rig. It is attached to an invidia fx 1400. For some reason though I can't get it to work directly from dvi. It will only work with a dvi-vga adapter which is plugged into the same output port. Any ideas on how to fix this? Thanks

Is it going into Power Save Mode when you connect it via DVI?

If so, see my thread here.

Also, my Dell has a mode button. Make sure its on DVI when you connect that cable. I know, but I had to mention it.

...what's an FX1400? The Quadro FX1400? Do you have the NVIDIA drivers installed?

Also, some video cards have had issues using the DVI output before Windows has loaded (in the BIOS screens and for the Windows install itself). You may not be able to use the DVI output until Windows has loaded the proper drivers for the card.

thanks for that link I downloaded the latest nvida driver but to no avail

My guess would be that you're using a DVI-A (analog only) cable, but the monitor requires a DVI-D (digital) signal. Or perhaps the card is not sending the digital signal over the digital pins in the DVI-D connector... instead only sending an analog RGB signal over the analog pins. In either case you'd get no video if you connect the cable to a DVI-D (digital only) DVI monitor, but would get video if you use a DVI->VGA adapter to extract the analog signal from the DVI connector and send it to the monitor's VGA input.

If the former, then buy a DVI-D (digital) or DVI-I (digital + analog) cable. If the latter... um... not sure how to fix that. Driver options in Control Panel maybe?

Pictures of the different types of DVI connectors can be found here.
