Abstract: In some examples, a method includes receiving, by a timing controller of a display device, an indication from an embedded controller of a computing device during a computing device startup procedure. In some examples, the method includes determining, by the timing controller, whether to access display image memory or computing device image memory based on the indication. In some examples, the method includes accessing, by the display device, the computing device image memory in response to determining to access the computing device image memory. In some examples, the method includes causing the display device to display an image from the computing device image memory in response to determining to access the computing device image memory.

Abstract: In example implementations, an apparatus is provided. The apparatus includes an interface, an integrated graphical processing unit (GPU), a discrete GPU, and a controller. The interface is to receive a connection to an external display device. The integrated GPU and the discrete GPU are communicatively coupled to the interface. The controller is communicatively coupled to the integrated GPU and the discrete GPU and is to deactivate the discrete GPU and activate the integrated GPU in response to detection of the external display device connected to the interface.

Abstract: Examples for generating a common video signal for an integrated GPU and the graphical processing device, based on a common display mode setting, are described. In an example, a common display mode setting is determined based on a first set of display mode settings supported by the integrated GPU and a second set of display mode settings supported by the graphical processing device. Based on the common display mode setting, video signals for the integrated GPU and the graphical processing device are generated.
