Hi

I'm using windows 7 on a desktop. my graphic card is Nvidia quadro FX580 (driver version 9.18.13.4195)

I can see the display in the device manager it is unidentified as Dell U2412M (Display port)

Dell Display manager (1.27.1792) doesn't identify the monitor. I get a balloon message saying that it requires supported Dell monitor. Older version of DDM didn't work either. 

The display is connected through HDMI port on the graphic card. I've tried the DVI connection as well, but same result. 

Only a single monitor is connected to the computer. DDC/CI on the monitor is enabled.

Resolution I'm using is 1920 by 1200 @ 60Hz

Thanks,

Ariel
