GTX 260 and UltraSharp U3419W

Iswan

I have an odd issue.

 

I am connecting an old Alienware Tower with a Nividia GeForce GTX 260 graphics card to my new Dell UltraSharp U3419W. The monitor gets a video signal during boot, but will not keep the signal through the boot process nor when in use. Now here is the odd part. If I connect my old monitor (ACER RH240HY for what it is worth) and Dell, the Dell receives a signal and can properly display either as an extended desktop or duplicated with the Acer. In full 3440 x 1440 I have to keep the monitor at 30hz, but otherwise it seems to work fine as long as the video card is connected to 2 monitors.

 

I am simply using this as a back up to do misc background task, so performance is not a big concern. I simply want easy access to the old computer using the KVM features in the monitor.

 

Here is my system:

And here is my current configuration

Any thoughts would be greatly appreciated.
