    Yep :)

    And also see if it's the correct screen (in case of multi monitor on your PC) is refreshed correctly :)

    This is great Sebastiii. Maybe we don't need EventGhost workarounds to use Dynamic Refresh Rate on the secondary monitor soon (y)

    I tested this build with two displays connected:
    1. ATI Radeon 5750 Card #1 - No display connected
    2. ATI Radeon 5750 Card #2 DVI - 2560 x 1440 monitor as primary at 60 Hz (no other refresh rates supported)
    3. ATI Radeon 5750 Card #2 MiniDisplayPort - 1920 x 1080 projector as secondary running MP at 50 Hz (24, 50 and 60 Hz supported among others)
    Playing a 24 fps video using MediaPortal from this Area 51 thread changes the secondary display to 24 Hz correctly and the correct stats are displayed:

    When using MediaPortal 1.4 final, then refresh rate is not changed and stats shows Display refresh rate from the wrong monitor.

    Now I also tested another setup and all is good :)
    1. ATI Radeon 5750 Card #1 DVI - 2560 x 1440 monitor as primary at 60 Hz (no other refresh rates supported)
    2. ATI Radeon 5750 Card #2 MiniDisplayPort - 1920 x 1080 projector as secondary running MP at 50 Hz (24, 50 and 60 Hz supported among others)
    I also tested setting the MediaPortal screen to primary as well.

    That good news :)

    So know it could be nice to port the change with Win7 API but after days of trying, seems really hard for me.
    So this branch fix the issue by using Win32 API and not WIN7 one.

    Hi Guys,

    Installer updated in first post (V3).
    Win7 API is back to have decimal value for refresh rate display stats (that needed also for C++ components (MPAR ?) :) )
    Little tweak to get the current screen setup in MP config and not where MP windows is.
    D3D init MP based on the screen selected in MP config, so we should stay on that value all the time (even if you move MP between screen) it keep this based reference.

    Strangely, on my WIN8, running Primary screen to 60Hz and a movie @ 50Hz on secondary monitor (it where i have set to start MP), the line were flat and no stutter :) (not sure if it's placebo or Win8).

    The only way (for me) to have flat line on Win7 when the setup is configured with multiscreen :
    • Where MP is displayed : the screen should be primary
    • or
    • Have the same refresh rate for both screen
    • or
    • Disable Aero (but Aero/Vsync is needed to avoid tearing )
    So right now on Win8 (flat line) and this mod i have :
    • MP screen not set to primary
    • Different refresh rate
    • Aero (integrated on Win8)
    Thanks :)
