    Can`t extend the display to my fourth monitor R9 390




      I have 3 displays 5760 x 1200 and 1 40" TV 1920 x 1080 connected to my graphic card an SAPPHIRE R9 390 Nitro 8G really nice card by the way, My displays are connected as follows: 3x in the display port using a DVI to display port adapter, TV HDMI.

      Whenever I try to extend my to my TV using the Radeon new software it throws me this intricate dialog box saying the following (To extend the desktop, a desktop or display must be disabled


      Am ruining on windows 8.1 64bit


      Please note I used to run all the above on 1 single AMD SAPPHIRE 7970 3G they were connected as follow 3x DVI 5760 x 1200, TV HDMI 1920 x 1080 and it was working fine. Now am having trouble connecting the same setup on the new card this is really frustrating please I really hope we can find an answer to this really troubling problem am used to work on the old setup.


      Thank you.

          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.
