Technologies for low-power display refresh standby include a computing device with a display such as an LCD panel. The computing device may include a system-on-a-chip (SoC) with a processor, I/O subsystem, display controller, and memory. When the computing device determines that a display image is static, the computing device enters a low-power display refresh standby mode, powering down unneeded components of the SoC such as processor cores, peripheral devices, and memory other than a dedicated display buffer. The display controller may access the dedicated display buffer via the I/O subsystem and output the image to the display. The computing device may power down the I/O subsystem and the dedicated display buffer when a display controller FIFO is full of image data, and periodically power on the I/O subsystem and display buffer to fill the display controller FIFO. Other embodiments are described and claimed.
