In Windows 7, DirectDraw cannot be disabled. What should I do?

In the Windows XP era, many users have been troubled by the "all black pictures" of videos. In this regard, there are two methods to solve the problem of blackening local playback. One method is to use two different players and open the same file at the same time; another method is to disable DirectDraw.

Users familiar with Windows XP and Windows 7 should know the default situation). DirectDraw is enabled in both Windows XP and Windows 7. The difference is that in Windows XP, users can disable it, while in Windows 7, it cannot be disabled. This also means that Windows 7 users cannot solve the problem of blackening through the "Disable DirectDraw" method.

By default, DirectDraw in Windows 7 cannot be disabled, but we can disable it using other work und methods:

Method 1: Modify the Registry

In Windows 7, run Registry Editor, locate HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ GraphicsDrivers \ DCI, find and double-click "Timeout" in the right window, and then, in the displayed window, change the default value "7" to "0 ".

After the modification, save the settings and exit. The modification takes effect the next time it starts.

Method 2: Install a dedicated Windwos7 driver

Some Windows 7 users may find that DirectDraw is still enabled in Windows 7 after the registry is modified and the computer is restarted. That is to say, DirectDraw cannot be disabled by modifying the registry.

In this case, the display card driver of Windows 7 is different from that of Windows XP. Some graphics card users need to download and install Dedicated drivers, some public drivers, and some drivers under Windows XP, in Windwos7, the DirectDraw status cannot be modified.
