Technologies for secure content display include a computing device having a display controller and a display. The display includes a self-refresh frame buffer. The computing device establishes a secure, attested communication session between the display controller and the display device. Attestation may be performed using an enhanced privacy identifier key provisioned to the display controller and/or the display by the corresponding manufacturer. The display controller may transmit protected content from a protected audio/video path to the display over the secure communication session. The display controller may transmit a command to the display to disable read back of the self-refresh frame buffer. The display controller may transmit a command to the display to clear the frame buffer. The display controller may transmit a predefined image frame from secure storage to the display. The predefined image frame may be an advertisement or user-defined content. Other embodiments are described and claimed.
