Windows 7: nVidia Quadro FX1500 dual montior problem!!?!?!?

nVidia Quadro FX1500 dual montior problem!!?!?!?

I put this in the general section, but it is probably more appropriate here.

Just have a issue regarding dual monitors on a windows 7 machine. I will provide as much information as possible:

I recently purchased a cheap graphics card - nVidia Quadro FX 1500 (2 x DVI) to run a dual monitor setup. My original monitor (Acer x243hq), connected to DVI via a VGA-DVI adapter and a newly purchased Samsung BX2440 (connected direct DVI).

Individually the monitor are each capable of a 1920 x 1080 setting, but as soon i plug in both monitors, the Acer resolution blows up and i am unable to see desktop icons and task bar (when it is set to primary, maximised window will be significantly cut of when set to secondary and have a internet browser open).

When i right click and go into "screen resolution", both screens are showing 1920 x 1080, but it is clearly not the case.

Is there any solution for this? I did a search and cant find anything regarding this.

The only solution i have is that the video card is having trouble running both monitors? The specifications however suggests it is capable of this.....

Any ideas??

Thanks in advance!


1. Went into the nVidia control panel, and both setting seem correctl. The primary screen (samsung) to "recommended" (1920 x 1080), the secondary screen to "native" (1920 x 1080).

2. If i plug the acer monitor in by itself (so computer runs only the one screen), the resolution is fine 1920 x 1080. However, the problem seems to only occur when both are plugged in at the one time. Once it is, the Samsung is fine but the resolution on the Acer seems "blown up"

3. Refresh rates:

Samsung (primary) is 60Hz
Acer (secondary and problematic!?!?) is 64hz

Recommended PSU for the card is 350W. I'm assuming you have that?
