Examples described herein generally relate to a display device and computing device where a display is configured for displaying images, a display controller is configured for receiving image data via a display port when coupled to a computing device, and sending signals to the display, based on the image data, to cause the display to display the images, and a memory is accessible by the display controller for storing a resume image received from the computing device. The display controller is further configured for detecting a power on event, accessing the memory to obtain the resume image, and sending signals to the display to cause display of the resume image based at least in part on detecting the power on event.
