[QUOTE="nyt, post: 562473, member: 98737"] Before I post the patch using DwmEnableComposition, I'm looking at DwmSetPresentParameters real quick to see if it will be a more elegant solution. Here's something else I noticed, the refresh rate actually gets set to 23970/1000 whether you request 24hz or 23hz, but the first mode validation fails for 24000/1000, 24000/10001, and 23000/1000. This can most likely be cleaned up, but that's up to scythe. *** 23 specified RefreshRateChanger.AdaptRefreshRate: framerate on file C:\movies\28 days later\xmf-28-days-later-1080p-x264.mkv is 23.976 RefreshRateChanger.SetRefreshRateBasedOnFPS: current refreshrate is 60hz - changing it to 23hz RefreshRateChanger.SetRefreshRateBasedOnFPS: using internal win32 method for changing refreshrate. current is 60hz, desired is 23 W7RefreshRateHelper.SetDisplayConfig(...): SDC_VALIDATE of 23/1 failed W7RefreshRateHelper.GetRefreshRate: QueryDisplayConfig returned 23970/1000 CycleRefreshRate: successfully changed refresh rate to 23.97Hz (23Hz requested) *** 24 specified W7RefreshRateHelper.SetDisplayConfig(...): SDC_VALIDATE of 24000/1000 failed W7RefreshRateHelper.GetRefreshRate: QueryDisplayConfig returned 23970/1000 CycleRefreshRate: successfully changed refresh rate to 23.97Hz (24Hz requested) *** 23.976 specified W7RefreshRateHelper.SetDisplayConfig(...): SDC_VALIDATE of 24000/1001 failed [/QUOTE]
