First, the forum question: am I doing something wrong? Ive done a few posts, and can't get anyone to post a reply? I think I've been nice in all my posts? That said, I could really use help on this. Stoked on my build, worked out most kinks, was all good to go, popped in my second monitor... Monitor seems all good to go, up to the apple loading screen (mirrored from main monitor), at which time the second monitor goes black. Tried a few suggestions, all were related to NVIDIA cards, which I don/t have or need. Any help is appreciated. I do a lot for work that requires both monitors so its a must have for me. I'm using the HDMI 2 port to go to a standard pavillion 23xi (older monitor, has standard HD). other is a Samsung LED, HD, but nothing special. using standard HDMI cables to and from the monitors. Note that either one plugged into the HDMI 2 plug work fine on their own. thank you.
