The put_SuppressEffects method sets preferences for power management and visual effects.
Syntax

[in] VARIANT_BOOL bSuppress
);
Parameters
- bSuppress [in]
Specifies a Boolean value. See Remarks for more information.
Return Value
Returns an HRESULT value. Possible values include the following.
| Return code | Description |
|---|---|
S_OK |
Success. |
Remarks
If bSuppress equals VARIANT_TRUE, the Video Control does the following:
- Disables font smoothing and the system-wide drop shadow effect. (Only when the Video Control is using hardware overlay.) This is useful if the application draws onto the overlay.
- Disables the screen saver, and turns off power management for the display. This is useful to prevent the operating system from interrupting playback while the user is watching a program.
The Video Control restores the original system settings after it stops.
If bSuppress equals VARIANT_FALSE, the Video Control uses the existing system settings.
Requirements
| Header | Declared in Dshow.h. |
