I can only use two of the three monitors at a time.
This is a Win7 Pro desktop PC with a GEForce 210 video card, with a VGA, HDMI, and DVI connector. The primary monitor is connected to the HDMI port. I have a DVI-VGA converter plugged into the DVI port. If I connect all three monitors, one of the non-primary monitors will be black. The 3rd monitor does appear on the Windows Screen resolution setup screen, but its icon is darker grey, and the Resolution and Orientation fields are greyed out. The Multiple displays field says Disconnect this display, and no matter what I change it to from the dropdown, it ignores me and goes back to Disconnect this display.
The Nvidia control panel only sees two monitors at a time, i.e. never three like Windows does, but if I disconnect one of the side monitors, then the Nvidia control panel "sees" the other side monitors and displays its model name correctly. Note that I just now downloaded the latest driver for the GEForce 210 and rebooted.
Is this card incapable of running three monitors, or am I doing something wrong? TIA
