Hello Kirara,
You have not stated how your displays are connected up, what wiring and ports are used, also you have not stated what monitors you are using but a resolution of 7680x1080 is the same as 4x 1080p monitors, or you are using 3x1 2560x1080 monitors?
IF you are using 4 monitors....
You are using Nvidia Surround, which is limited to a maximum of 3 monitors in a single large surface group, with the 4th display to be used as an extra accessory/extended display.
Nvidia will not allow you to add this 4th monitor into the Nvidia Surround display group due to the Surround limitations.

http://www.wsgf.org/article/amd-eyefinity-faqThe Nvidia Quadro and the AMD FirePro cards do support 4x1 configuration however these are much more expensive cards as these are designed for multi-head workstations and are CAD certified and optimized.
IF you are using 3 monitors....
If I recall, the way Nvidia Surround works is to have one or two of the outputs set to DVI single-link mode, which provides a maximum output resolution of 1920x1200@60hz which is insufficient bandwidth to display the monitors at a native resolution, this could also be why you are falling back to the 5760x1080 resolution, as the DVI-single link connector is your weakest link causing all displays to fall to the same bandwidth/resolution of 1920x1080 each.
The issue could also be if your using an active displayport to DVI/HDMI adaptor that is limited to 1920x1200@60hz resolution.
Could you please detail how you have each display connected and to which port on the card?
I suggest you check the Nvidia surround config tool -
