Graphic issue and Multi Display

Hey guys I cant get my head round this.

I orignally had a Nvidia 7300 LE, upon installing 7 it would say out of range, even with the latest drivers it still would not work unless I disabled the card all together.

So I purchased a Gigabyte GTS 250 which arrived today and have installed.

This has resolved my Aero functions, which I could not use due to onboard graphics.

But now in my Nvidia control panel I cannot enable my second monitor, I check the box and apply but the screen remains blank and the box gors back to not having a tick inside it.

I am missing something obvious.......???

Same problem.

I can clone the display but i cant extend it, the 2nd monitor just remains black

any ideas?

Right I've update my driver via Windows update.

Now the problem is my resolution, i can extend my 2nd monitor but only if it's on 800x600 if I try to put it on 1024x768 (exactly the same as my 1st monitor) it says out of range, but if the 2nd is clone display on 1024x768 it works...... WTF????

The second monitor connected to the new video card or still connected to the onboard video?

I've fixed it now so not to worry thanks tho guys :)

oh how do i mark posts as sucessful or is that admin/moderator duties?

Instead of using the windows setting rightclickdesktop/screenresolution, I had to go into my Nvidia control panel and the refresh rate was set at 85Hz!!!

So just knocked it back down to 60Hz... Problem resolved

Thanks anyway guys :)
