Native resolution problem on Ultrawide LG-25UM65-P Monitor and EVGA GTX 780 ti card

[Akira71]

I just purchased this monitor and I have tried setting it to the maximum resolution of 2560 x 1080 and it just flickers crazy and acts strangely. I know this graphics card can power the monitor. I have tried several DVI-D cables to see if that was the problem and they all exhibit this behavior.

The monitor is very stable at 1920 x 1080 resolution and I am using a single DVI-D cable. Is this a case where I have to use Dual Link?

Got the exact same issue, did you solve it already?

Yes you need to use a DVI Dual link cable and connection, not to be confused with DVI-D which can be single or dual link.

Did any of you guys ever figure this out? I just got this monitor and was going to RMA because i have the same problem with two different GPUs and all different cords

The answer to this was the Dual Link DVI cable. That allowed me to get it up to full resolution no problem. Thank you all for the help!
