Hey guys, I just bought a new LG display that has a 1920x1080 23" display. I am hooking it up to my Mac Pro via HDMI to a mini displayport to hdmi adapter. However, the highest resolution its giving me is 1440x900, with black bars on either side of the display. When I try to change the settings, I get two different resolution choices: Any help on how I can get my mac to display properly? It would be greatly appreciated!
