What does it mean to enable hardware acceleration?

Enable hardware acceleration What does it mean to play games and watch movies faster or slower after you enable hardware acceleration, which is turned on by default and how to turn off hardware acceleration.

In short, hardware acceleration is the use of hardware modules to replace software algorithms to take full advantage of the inherent fast features of hardware. Computer display hardware acceleration will be faster, but it will be in the projector or screenshot found that the display area is black, then turn off hardware acceleration (hardware accelerated reverse operation)

Some video cards and sound cards support hardware acceleration, but not all video cards and sound cards support hardware acceleration. Graphics and sound cards that support hardware acceleration, and appropriate drivers are installed to support hardware acceleration normally.

In fact, the hardware acceleration can be turned off in the user interface. If you have to have a graphics card to support hardware acceleration, you can generally use the following methods to close.

Turn off graphics hardware acceleration:

1. Right-click the desktop, screen resolution.

2. Click Advanced Settings.

3. Click Troubleshoot, change settings, and drag the pointer from full to none.

4. Click OK.

Turn off the sound card hardware acceleration:

1. Right-click on the lower right corner of the volume icon, playback equipment.

2. Click on the playback device, properties.

3. Turn off all advanced sound effects under the Advanced tab.

Without the above settings, your hardware or driver does not support hardware acceleration. In addition, some of the video player settings options can also be on some high-definition video files to turn off or turn on hardware acceleration.

If you cannot set it through the interface, you can modify the registry directly.

Note: Run the command prompt and execute the command as an administrator

Registry Editor

To open Registry Editor, locate the registry key to Hkey_local_machinesystemcurrentcontrolsetcontrolvideo{187826e1-5903-40a9-ba63-0ed7d45282a8} 000

Viewing acceleration.level with a key value type of REG_DWORD on the right if its value is 0, it indicates that it is fully enabled for graphics acceleration. A value of 5 indicates that the graphics acceleration is completely disabled.

{187826e1-5903-40a9-ba63-0ed7d45282a8} may vary according to different video cards

After you change settings, you must restart your computer.
