  1. I have this issue too. My Hardware: Gigabyte EP45-DS3P Core2Quad Q9300 9800GTX+ 512MB I have 2 DVI and DVI to HDMI connected to plasma TV. In Snow Leopard 10.6.0 dual display works unitl I update system to 10.6.1 or other. In mavericks don't work. I have not found a solution for several years from 10.6 to 10.9
