did you download the latest nvidia driver for your card? if not here is the link, suggest you install them. (it is suggested to uninstall old drivers first)
Drivers - Download NVIDIA Drivers
also being an led monitor you most likely need to install drivers for your monitor, you can find these on the manufactorers website.
once they are compatible, if at all possible, the resolusion should automaticly set for the native resolution of the monitor.
if not you can right click your desktop and select "screen resolution" and in window popping up you can change the resolusion.
good luck
