I just bought a Radeon HD 6850 and am trying to understand how to make it work with two monitors. I have two adaptors. Each work on the first port, but when trying to get the second working, nothing. I can't find any documentation or support which came with the product to explain how this is supposed to work. Is there a simple fix to this or am I doing something wrong? AMD and Radeon Support will not respond after 6 days. This is on a ASUS P8P67 LE motherboard, Corsair TX 750W power supply.
