Regarding the display issue, its not the R9 290 at fault but the new drivers starting from 14.0. From drivers 14.0 and upwards, when U power off a display and power it back on, it is treated as it the display was physically disconnected. Try driver 13.12 and you'll find the behavior gone.
I have a triple display setup, 2 monitors and an HDTV, and my 3 cards from the latest 3 AMD generations(6950, 7950 and R9 290) exhibit the same behavior. Its so frustrating since I occasionally turn off other displays when focusing on the primary monitor or HDTV only to experience the same issue as you when I turn them back on.
Sticking to 13.12 is no longer an option considering a lot of the new games benefit from the new drivers.
