The graphics co-processing technique includes receiving display operation for execution by a graphics processing unit on an unattached adapter. The display operation is split into an encrypt content by the graphics processing unit on the unattached adapter, a copy from a frame buffer of the graphics processing unit on the unattached adapter to a buffer in system memory, a copy from the buffer in system memory to a frame buffer of graphics processing unit on a primary adapter, a decrypt the encrypted content in the frame buffer of the graphics processing unit on the primary adapter, and a present from the frame buffer of the graphics processing unit on the primary adapter to a display. Execution of the copy from the frame buffer of the graphics processing unit on the unattached adapter to the buffer in system memory and the copy from the buffer in system memory to the frame buffer of the graphics processing unit on the primary adapter are synchronized.
