Windows 7: Dual monitor resolution issue?!

Dual monitor resolution issue?!

Didnt really know which area to post this in, so i thought this was the most suitable.

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!

Check the NVidia control panel for resolution settings there, set it to the native resolution for each monitor.

Also, get a straight DVI to DVI cable for your monitor, that might have something to with it.

Check your refresh rates for each monitor as well.

bassfisher6522, thanks for the reply.

1. Went into the nVidia control panel, and both setting are set correctly. The primary screen (samsung) to "recommended", the secondary screen to "native"

2. If i plug the acer monitor in by itself (so computer runs only the one screen), the resolution is fine. However, the problem only occur when both are plugged in at the one time.

3. Refresh rates:

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

Change the Acer to 60 hz.

Try switching the monitor ports out. That is reverse your current connections.
