Problem with DK2. Resolution not changes

Such a picture I see at the Oculus DK2 when rotate my head http://imgur.com/2gLiZcI (The image splits on two or three even at 75 FPS) I've tried to change screen resolution, but nothing changed. Windows shows resolution 1920x1080x75Hz but "Oculus World Demo" shows 2364x1461 and "OculusUnityDemo" shows 2402x1461. All drivers are updated and installed without errors. I've tried all settings of GPU and Rift. DxDiag shows no errors. GPU is Radeon HD 6770.
Please help me!

    The resolution thing is fine. Internally the games will alter to a higher res for better quality.

    The double image is not normal.

    Are you sure you are not running a 3D driver in the background (like Nvidia 3D Vision or TriDef)?

    I've been getting this double image on the headtracking in my dx11 engine aswell when ever there is even a little extra load such as compute shader hbao or just high geometry load. happening in both direct and extended modes.
    still looking into it on my engine side of things to make sure there isn't something interfering like there was with my dx9 engine but not looking easy to find at the moment. but it may not be the same issue as mine as Tuscany in the sdk doesn't do it.

    How can I check it?

    Yeah! It is impossible for eyes to play demo with FPS lower than 75!

    Games do not provide the ability to change resolution. Could it be that the Rift's driver does not support my video card? (Radeon HD 6770)

    not hijacking thread just toting in on the double image issue...

    turned out in my dx11 engine i was getting 37 fps which was the cause of the double image. This happened in extended and direct mode. I made some changes in engine and was able to get close to 75 in extended mode, but not all the way consistently but direct mode is still only giving me 37fps. I did expect my dx11 engine to perform better than my dx9 engine but the same scene in dx9 is a solid 75fps-90fps extended mode (fullscreen) direct mode doesn't work as I've mentioned previously though. not sure what to make of it all but will keep at it for a few more days and see if i can't crack it. if not I'll just stick to dx9 as at least that is consistent in performance.

    Edit: just read in the unity thread about disabling vsync for dx11 and in my engine i get in the scene 64 - 90 fps in direct mode though and no longer producing double images just judder when drops a little framerate and tearing. so any solution to the massive drop to 37 fps with sync on?

    genetransfer,
    In extended and direct mode in full and windowed screen mode I see double image even at 75 FPS!

    Resolution is normal. Timewarp doesn't work! Timewarp works only in Oculus World Demo sdk 0.4.4. This is the cause of my double image! How to force timewarp in another demo?
