Abstract: An information handling system includes a host processing system and a Liquid Crystal Display device. The host processing system includes a graphics processing unit (GPU) and the LCD device includes a memory device and a DisplayPort Configuration Data (DPCD) register. The host processing system 1) determines whether the first GPU supports a Dynamic Display Shifting (DDS) mode, 2) when the GPU does not support the DDS mode, provides a first indication to the LCD device that the GPU does not support the DDS mode, and 3) when the GPU supports the DDS mode, provides a second indication to the LCD device that the GPU supports the DDS mode. The LCD device retrieves a Panel Self Refresh (PSR) setting from the memory device and stores the PSR setting to the DPCD register in response to the first indication, and retrieves a DDS setting from the memory and stores the DDS setting to the DPCD register in response to the second indication.

Abstract: An operation method of an electronic system includes the following steps. When a first communication module of the electronic device receives a call signal, a controller of an electronic device detects whether an expansion device is electrically connected to the electronic device. Based on a result of the controller detecting whether the expansion device is electrically connected to the electronic device, it is determined whether the electronic system performs sound amplification with a first speaker of the electronic device or performs playing with a second speaker of the expansion device.

Abstract: A laptop computer including a main body, a fan disposed in a receiving space of the main body, a keyboard assembly movably disposed on the main body, and a heat dissipation assembly movably disposed in the main body and linked with the keyboard assembly is provided. The main body has an air outlet and at least one first air inlet. In a process of the keyboard assembly gradually moving out of the main body, the keyboard assembly drives the heat dissipation assembly to move in the main body and form a second air inlet in the main body to communicate with the receiving space.
