WM_CAP_DLG_VIDEODISPLAY
The WM_CAP_DLG_VIDEODISPLAY message displays a dialog box in which the user
can set or adjust the video output. This dialog box might contain controls that
affect the hue, contrast, and brightness of the displayed image, as well as key
color alignment. You can send this message explicitly or by using the
capDlgVideoDisplay macro.

lParam = 0L;
Return Values
Returns TRUE if successful or FALSE otherwise.
Remarks
The controls in this dialog box do not affect digitized video data; they
affect only the output or redisplay of the video signal.
The Video Display dialog box is unique for each capture driver. Some capture
drivers might not support a Video Display dialog box. Applications can determine
if the capture driver supports this message by checking the
fHasDlgVideoDisplay member of the
CAPDRIVERCAPS structure.
