Intellect allows you to select the video image processing mode prior to displaying it using the video card resources and DirectX libraries.

The video image processing improves the image due to optimization of the pixel color settings. At the same time, the CPU’s load is reduced, as the video image is processed with the resources of the video card.

There are three display modes in Intellect:

  1. Direct3D. In this mode, more modern, but less stable Windows graphics libraries are used. The mode is used when it is necessary to display the video from Fisheye cameras or the signal decoded using Intel QuickSync technology. This mode is also used if the DirectDraw mode is not supported by a video card.

    Note

    The Direct3D mode will be enabled automatically when its usage is specifically necessary to display the video, for example, if there is a Fisheye camera on the layout. The manual modes selection is available for the cases when there are display problems, and it is necessary to switch modes manually.

  2. DirectDraw (recommended). In this mode, more stable Windows graphics libraries are used. Currently, the DirectDraw and Direct3D features are about the same. This mode is used by default if Direct3D is not specifically required to display the video (see the note above).
  3. Programmed. Video signals from cameras are not processed by a video capture card.

As a rule, the DirectDraw is the optimal display mode. This mode is supported by the most of the video capture cards. If a video capture card doesn’t support the selected display mode, then a video signal is displayed with a big slowing-down.

Note

For correct display mode operation in Intellect, installed as a Server, set the 0 value for the NoDesktop text parameter in the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer registry section. This parameter is for displaying icons on the user desktop.

To select a display mode, do the following:

  1. Go to the settings panel for the Monitor interface object.

  2. Select the required display mode in the Display drop-down list in the Basic settings tab (1).

    Note

    There is a description of the selected display mode in the field below the Display drop-down list (2). 
  3. To save all the changes, click the Apply button (3).

The display mode is now selected.
