    R9 Fury & 4K TV : Pixel format window disappeared & can't switch from 8 to 10 bit anymore.

    makara

      Hello,

       

      I have a problem with my Sapphire R9 Fury Tri-X and my 4K Samsung UE55KS7500 (= US KS8500)

       

      As the title say, since maybe 2 monthes, I can't choose my pixel format & bit depth anymore. Everything worked fine when I got the TV.

       

      The pixel format window disappeared and now only the bit depth tab is available in the AMD control panel. I can choose 10 bit but it goes back to 8 after a short black screen.

       

      I tried every drivers from November (even some older) to today ; changing resolutions / refresh rates : nothing changes.

       

      I've read that a recent drivers fixed the pixel format problem, but mine is still here

       

      Any idea on what I could try to get those back ?

       

      Thank you very much
