In today’s post, we’ll explain why video playback can fail when DirectX 9 overlays are required in Windows 10 – and then suggest the solution to fix the problem. DirectX is a set of components under Windows that allows software, mainly and especially games, to work directly with your video and audio hardware. Games that use DirectX can more effectively use the multimedia accelerator features built into your hardware, improving your overall multimedia experience.
Early versions of Microsoft Windows (XP and earlier) included multiple versions of DirectX that had to be installed separately. Later versions of Windows included DirectX, some of which can be upgraded. Below are the latest versions of DirectX for different versions of Windows.
-
Windows 10 = DirectX 12.
-
Windows Vista, 7 and 8 = Up to DirectX 11 (Vista released with DirectX 10).
- Other windows version = Up to DirectX 9.0c depending on the version of Windows.
Video playback may fail when DirectX 9 overlays are required
According to Microsoft, you may experience this problem for the following reason;
Some older video applications may depend on DirectX 9 overlays to function properly. In Windows 8.1, there are rare scenarios in which DirectX 9 overlay hardware is not available. In these situations, video playback does not work.
In Windows 10, these scenarios are still rare, but they can occur more frequently than in Windows 8.1. This is especially true when your display options are set to a resolution lower than the native screen resolution.
To work around this problem, reset the display resolution to the native screen resolution.
However, if your display options are already set to the native screen resolution and this problem persists, quit all open applications and then restart your video application. You can also run the DirectX diagnostic tool and see if it helps.
