I recently purchased an Asus HD 6670 Video card to pair with my A8-3870K APU. I have the dual graphics enabled, and after plenty of hiccups and time on many forums getting it setup properly, the dual graphics are working, but if I put my computer to sleep when I wake it up I have no display from either of my monitors. Both monitors are plugged into the discrete graphics card. I have to hard shut off my PC and reboot it for the displays to work again. I have a feeling that its trying to use the onboard graphics when coming out of sleep, but even when switching cables to the onboard no display will show up. I was running the latest catalyst software but I updated to the beta version 13.3? it think to try and solve this problem. Needless to say it didnt help.
