I'm hoping someone can help me with this.

I had a EVGA GTX 280 which was sent back for repairs because I thought it was causing a problem.  A new card was shipped back to me.

Among other things, I use my monitor using the nVidia two-monitor setup, using "extend mode" so both monitors in effect become a much wider screen.  My old card was set up this way.

With the replacement card, looking at the computer as seen from the rear, the DVI output on the "right" (furthest from the motherboard) works fine, and as far as I can tell, there are no issues.

However, there is nothing I can do to get any kind of image from the other DVI output.  I've tried "dual mode", "clone mode", and just hooking up a single cable only to that DVI connector.  I've tried two different monitors, and two different cables.


Is there some "trick" to turn on that other DVI connector, or is this new card defective?   (I think I had a similar problem years ago, and a friend fixed it very easily, but I don't remember what he did.  If it means anything, the video card I was using while this one was being repaired worked fine in dual-channel mode.  The drivers were uninstalled when we removed the old card, and the new drivers were installed after the 280 was connected to the system.

hold winkey and press 'p' 3 times, it should kick _windows 7_ into extend mode, and not the nvidia drivers.

worth a shot at any rate.

Have you tried to connect the monitor only to the DVI closest to the mobo, then restart the computer?  If you still do not get any video, try powering off you monitor and then back on.  For some reason this happens to me every once in a while.  If that doesn't work, try reinstalling the drivers using driver sweeper to clean the registry.

Let's see if I get all this right.  I'll be back in front of the computer Monday morning.

Step 1 will be to:
   hold winkey and press 'p' 3 times, it should kick _windows 7_ into extend mode, and not the nvidia drivers.
This will make the system use the Windows drivers, and eliminate any errors if the nvidia drivers are confused.


Step 2 will be to:
   Once again, "connect the monitor only to the DVI closest to the mobo, then restart the computer? 
   If you still do not get any video, try powering off you monitor and then back on. 
   If that doesn't work, use something like "driver sweeper" to clean the registry, then reinstall  the drivers 

Step 3, as of now, would be to send the card back to EVGA.

(I wish I had a spare computer I could use to test out the card, in case the problem is with the computer, not the card...)

That is an excellent idea.  I'll do that on Monday.  Is the phone number posted on the EVGA site?  (I found it once, then couldn't find it a couple of weeks later...)   Will check now.

It's far more likely that I'm the one doing something wrong, but I have no idea what.

Thanks again!

Yeah, these types of issues are best troubleshot over the phone.  So much easier than making a post, testing, and then coming back to make another post.
