1. Hardware acceleration setting is too high
Hardware acceleration can make software that processes a large number of graphics run more smoothly, but if the computer hardware acceleration is set too high, it may cause a "black screen" phenomenon. To resolve the "black screen" glitch, first try reducing hardware acceleration.
1. Click the Windows "Start" menu, click "Control Panel", and then double-click "Display".
2. Select the "Troubleshooting" tab, and under "Hardware Acceleration", gradually drag the slider from "Full" to a position close to "None".
3. Click the "OK" button.
2. Disable 3D acceleration or upgrade the graphics card driver
If Windows has been configured for 3D acceleration, but the graphics card does not support this feature, a "black screen" failure may occur when running a game or multimedia program.
1. Click "Start", then click "Run", then type "dxdiag" in the "Open" box and press the Enter key.
2. Select the "Display" tab and click the "Test Direct 3D" button under "DirectX Function" to obtain the correct Direct 3D function.
3. If a rotating cube does not appear on the screen, it means that the graphics card does not support 3D acceleration. At this time, please click the "Disable" button after "Direct 3D Acceleration" to disable this feature.
If your graphics card does not support 3D acceleration, in addition to disabling this function, you can also contact the graphics card manufacturer to update the driver so that it supports DirectX 3D acceleration.
3. The graphics card driver is incompatible with the graphics card
The DirectX installer may incorrectly detect the graphics card and install a driver that cannot drive properly. Please confirm whether the graphics card driver used is correct.
1. Click "Start", then click "Control Panel", and then double-click "System".
2. Select the "Hardware" tab, click the "Device Manager" button, then click the " " sign before "Display Card" or "Display Adapter", then right-click the display adapter under it, and then Click the "Properties" button.
3. Select the "Driver" tab and click the "Driver Details" button to display the graphics card driver used. If the driver you are using is incompatible with the graphics card, click the "Update Driver" button in the "Driver" tab, and then follow the on-screen instructions to install a new version of the graphics card driver.
