I am having a problem with my NEC MultiSync EA261WM as a second monitor on my iMac. The monitor is 26inches and has a native resolution of 1920x1200. According to the iMac tech specs the Mini-DVI connector has the capability of outputting 1920x1200 to a secondary monitor. The picture looks ok but it is actually detecting the display as a TV. This requires me to use the "Overscan" setting to stretch the picture out to the entire screen. Again, it doesn't look bad, I just feel like I can get more out of the quality of this display. It looks fine and is detected fine on a windows machine. I am using a DVI-D cable and the Apple Mini-DVI to DVI-D adapter. I hope someone can help me, I've spent hours trying to troubleshoot this thing with no luck. Its getting very frustrating. Here are some screen shots.
