An apparatus for controlling a stereo 3D display includes an on-screen buffer, two off-screen buffers and a stereo window controller. The on-screen buffer stores screen image data including window image data. The two off-screen buffers are of a double-buffer architecture, wherein one off-screen buffer stores the left image data and the right image data of a current frame, and another off-screen buffer stores the left image data and the right image data of the next frame of the current frame. The stereo window controller controls swap operations and BITBLT (Bit Block Transfer) operations. The swap operations determine which one of the two off-screen buffers stores the left image data and the right image data of the current frame. The BITBLT operations alternatively transfer the left image data and the right image data of the current frame to the on-screen buffer as the window image data.
