Provided are an image display method and apparatus, an electronic device, and a medium, which relate to the field of computer technologies, in particular to the fields of cloud phones, cloud computing and cloud services. The specific implementation scheme is as follows: generating a simulated external display of a cloud device according to an acquired target resolution of a target client; and generating frame buffer data according to a frame buffer area of the simulated external display in the cloud device, and sending the frame buffer data to the target client so that the target client performs image display on a target interface according to the frame buffer data.

An image system dynamically updates drive sequences in an image system. Drive sequences are image display settings or display driving characteristics with which a display is operated. The image system may determine the drive sequence at least partially based on input from one or more sensors. For example, the image system may include sensors such as an inertial measurement unit, a light sensor, a camera, a temperature sensor, or other sensors from which sensor data may be collected. The image system may analyze the sensor data to calculate drive sequence settings or to select a drive sequence from a number of predetermined drive sequences. Displaying image content on a display includes providing the display with image data and includes operating the display with various drive sequences.
