When capturing the 3uAirPlayer window in OBS, if the video appears black-and-white or only partially displayed, you can resolve it using the following steps:

Step 1: Open OBS Window Capture Settings

In the Sources area on the main OBS interface, locate the already added Window Capture source.

Right-click the source and select Properties (or double-click the source directly) to open the Window Capture Settings window.

Step 2: Modify Capture Method

In the Window Capture Settings window, locate the Capture Method dropdown menu:

• If it was originally set to BitBit (Windows 7 or newer), change it to Windows 10 (1903 or newer).

• You can also check “Allow Transparency / Borderless Mode” to improve the video display quality.

Step 3: Apply Settings and Confirm

After making the changes, click OK to apply the settings.

Return to the OBS preview interface, and the 3uAirPlayer video should now display normally. The black-and-white or partial screen issue will be resolved.

Explanation

The core reason for this issue is that the older capture method has limited compatibility with higher version systems or certain versions of Windows.

Switching to the Windows 10-optimized capture method allows OBS to match the rendering mechanism of the 3uAirPlayer window, ensuring the video displays correctly.
