I am using a 50" Sony LCD TV with Mac Mini via DisportPort to HDMI adaptor. I am getting parts of the Dock and non of the top menu bar, why? The only setting that looks right is setting the display output to 1080x720 (overscan on). Anyother settings will not fit the screen and crops both top & sides. Here is the TV specs. What am I doing wrong? Sony's Description Compared to enhanced definition televisions and other technologies, the Grand WEGA TVs deliver natural color reproduction and exceptional brightness levels due to 3LCD technology with 1280 x 720 native 720p resolution. Additionally, since 3LCD technology simultaneously projects three full-time red, green and blue images, there is no color breakup or "rainbow effect" that may cause eyestrain or visual fatigue.
