Disabled DirectDraw video screenshots in Windows 7 are no longer black

In the Windows XP era, many users have been plagued by "all black pictures" after video screenshots. In this regard, in the solution to the local playback when the screenshot becomes black, there are generally two ways to solve, one method is to use two different players, open the same file at the same time; another method is to disable DirectDraw.

Users familiar with Windows XP and Windows 7 should know (by default) that DirectDraw is enabled under Windows XP and Windows 7. The difference is that users can disable it under Windows XP, and it can't be disabled under Windows 7. This also means that Windows 7 users can't solve the blackening problem of the screenshot by "disabling DirectDraw".

By default, DirectDraw under Windows 7 cannot be disabled.

By default, DirectDraw in Windows 7 cannot be disabled, but we can disable it by other workarounds:

Method 1: Modify the registry

Under Windows 7, run the Registry Editor, navigate to HKEY_LOCAL_MacHINESYSTEMCurrentControlSetControlGraphicsDriversDCI, then double-click "Timeout" in the right window, and then change the default value of "7" to "0" in the pop-up window.

Modify the registry

After the modification is completed, save the settings to exit, and then take effect the next time you start.

Method 2: Install Windwos 7 dedicated driver

Some Windows 7 users may find that after modifying the registry and restarting the computer, DirectDraw is still enabled under Windows 7, ie By modifying the registry method, the purpose of disabling DirectDraw is not achieved.

This situation occurs because Windows 7 differs from Windows XP in terms of graphics card driver. Some video card users need to download and install dedicated drivers, some public version drivers, and some Windows XP under Windows 7. Under the drivers, they cannot modify the state of DirectDraw under Windwos 7.

Edit Comment:

From the small problem of solving the "video screenshot" blackening, we can see that compared with Windows XP, many aspects of Windows 7 are not just functional and operational habits. The difference. At the hardware driver level, Windows 7 has more requirements. If some common problems encountered under Windows XP cannot be solved by the "general" method under Windows 7, then users need to broaden their thinking and start from a more flexible aspect.
