Remarks

Configuration of the end-user computers

Depending on the configuration of the end-user computers, the DDW feature may have no effect.
Indeed, the DDW feature is affected by the characteristics of the video card, the speed of the processor, ...
If a problem occurs, ask the end users to update the driver of their video card.
Remark: To operate, the end-user computers must:
  • have a display mode greater than 256 colors.
  • be in 32-bit or 64-bit mode.
  • be running Windows 2000 or later.
  • use the maximum level of "Hardware acceleration" for the video card (advanced display properties of the computer).

Rate of gray

The default rate of gray for the windows is set to 18 %. To modify this rate, use WinRateDDW.
