I use Dell T1650 workstation. It has Quadro 2000 graphic card.
I was using 1 VGA monitor with a DVI-VGA converter.
Now I need 2 monitors, I'm tring to connect an other VGA monitor. Quadro 2000 has display port, using displayport-DVI-VGA converter, 2nd monitor is black screen.
Do you think serial 2 converters connected cause this problem?
It looks like they are both connected and working, I think you just have to activate the second monitor. Nvidia control panel should have a sub category labeled - Set up multiple displays. From here you should be able to activate and configure both monitors.
