// FUNCTION NAME: NvAPI_SetRefreshRateOverride
// DESCRIPTION: Override the refresh rate on the given display/outputsMask.
// The new refresh rate can be applied right away in this API call or deferred to happen with the
// next OS modeset. The override is only good for one modeset (doesn't matter it's deferred or immediate).
//
// SUPPORTED OS: Windows XP
//
//
// INPUT: hNvDisplay - the NVIDIA display handle. It can be NVAPI_DEFAULT_HANDLE or a handle
// enumerated from NvAPI_EnumNVidiaDisplayHandle().
//
// outputsMask - a set of bits that identify all target outputs which are associated with the NVIDIA
// display handle to apply the refresh rate override. Note when SLI is enabled, the
// outputsMask only applies to the GPU that is driving the display output.
//
// refreshRate - the override value. "0.0" means cancel the override.
//
//
// bSetDeferred - "0": apply the refresh rate override immediately in this API call.
// "1": apply refresh rate at the next OS modeset.
//
// RETURN STATUS: NVAPI_INVALID_ARGUMENT: hNvDisplay or outputsMask is invalid
// NVAPI_OK: the refresh rate override is correct set
// NVAPI_ERROR: the operation failed
