More specifically, i am trying to use my integrated intel HD by plugging my monitor onboard, while mining with my 290 that has no monitor connected. (290 is detected in hardware but i cant seem to mine on it, for example GUI miner doesnt detect it).
Help would be much appreciated.
Follow this guide:

Besides they say dummy adaptor has no longer been needed for 2-3 years as software has evolved. But i don,t see any option in display setting or amd control panel to force enable idle GPU. So i'm looking for a software fix.
