Really weird Issue with geforce GTX 670

Hi Guys,

I have two eizo coloredge 24" (CE240W) displays which were running fine with my old Quadro FX 4600, so I have replaced that graphics card for a Geforce GTX 670 (PNY), unfortunately I can't get it working using the native resolution (1920x1200) of them. every time when I set that resolution it displays the image using only half of the horizontal resolution (kinda of stretching the image), apparently it is working fine when I set any resolution bellow of 1920.

These displays are plugged using DVI cable, and I'm using the latest nvidia driver.. (actually, it is happening even when I'm not using any driver (fresh windows install for example...)).

I wonder if it could be some problem in my graphics card ? Have you ever seem this kinda of issue before ?

I have took a picture about how it's being displayed when I set the native resolution:

Thanks in advanced.

Quick update, actually when I set the native resolution (1920x1200) the display is receiving 960x1200, so it is very weird because in the windows it shows as being displayed as 1920x1200 and the display says that is receiving the resolution 960x1200.

Here the full information about what the monitor is receiving:
960x1200
FH: 74.5kHz
FV: 59.8Gz

*The display is plugged using DVI cable

Cheers

Did you get latest drivers from nvidia?
Did you go to the Nvidia Control Panel and set resolution on their? Dont set it on windows properties. Right click on screensaver, and it should be their.

I upgraded from a gtx 295 to gtx 680 with seamless integration. Put back gtx 295 and with same settings running dual monitors without setting everything up. Make sure you make left side monitor one, and right side monitor too, by detecting.

Thanks KrAzYaZnFLiP808 for your reply.

I found where is the problem, it was a little bit trick, so I'm gonna post how to fix it detailed later to help people who is having the same issue!
