Default Re: Nvidia Quadro 420 and dual 30" monitors

Do you mean the Quadro NVS 420? That board has two GPUs on it, each of which is capable of driving two displays. To use TwinView however, you need to make sure the monitors are connected to the same GPU. Which ports of the breakout cable do you have the monitors plugged in to?

If you still can't get it to work, please follow the instructions in the sticky post to generate an nvidia-bug-report.log.gz file with verbose logging and attach it here.
