I had the same problem with my R9 290
so i deïnstalled the crimson drivers, installed the catalyst drivers
find my 3 monitors + tv
order them in the correct order. and made a PRESET !
switched to eyefinity where i only use 3 monitors, and made also a PRESET
then i updated to the latest crimson software, and thanks to my presets, i can swith back and forth.
however whith the catalyst drivers, i could swith my monitorpresets by clicking on the CCC taskbar icon next to my clock
with these latest drivers there are no presets to choose grrrr...
( i have to enter the settings page, than go to preferences, and then go to more settings. and then i can choose my presets )
also in start, AMD, presets, the folder is empty, so no presets that i made are there
I hope in next update drivers i will be able to order my monitors when i'm not in Eyefinity, and that i can choose my monitor presets directly
by clicking the taskbar icon.
