connect iMac to LG 27UK600-W display

I have connected my 2012 iMac to my LG 27UK600-W monitor via the thunderbolt 2 to HDMI connection. It connects, but the resolution is 640 x 480. How can I get a higher resolution on this monitor? Is there a special driver I need to install? I've tried the monitor controls, but when I switch to a full resolution on the monitor, I get a very small rendition of the 640 x 480 on the LG monitor. So It seems like something has to be done on the iMac end to transmit a higher resolution.

Go to Apple > System Preferences > Displays > Display > hold the Alt (option) key > click on the Scaled button and select a higher resolution.
