This application provides a display method and a device and relates to the field of communications technologies, so as to display different content on a terminal and an external display apparatus. A specific solution includes: displaying, by the terminal, a first screen, and instructing the external display apparatus to display a first desktop including a first application but not including a second application, where the first screen is different from the first desktop; and displaying, by the terminal in response to a first input of a user on the first screen, a second screen including the first application and the second application on the terminal, and instructing the external display apparatus to display a second desktop including the first application and the second application.

An apparatus, method, and computer readable medium that access a frame buffer of a graphics processing unit (GPU), analyze, in the frame buffer, a frame representing displayed data, based on the analyzed frame, identify a reference patch that includes an instruction to retrieve content, generate an overlay including an augmentation layer which includes the content, superimpose the overlay onto the displayed data such that the content is viewable while a portion of the base layer is obscured, detect a user input, determine a location of the user input in the augmentation layer, associate the location in the augmentation layer with a target location in the base layer, and associate, within memory, the target location with an operation such that the user input in the augmentation layer activates an input in the base layer.

The present disclosure discloses a method and device for controlling screen display. The method includes that: a rotation instruction is received; a system window of a screen is rotated according to the rotation instruction, wherein when the system window is rotated, the absolute position of a play window in the system window changes accordingly; the play window is translated to a preset position in the system window; and a display image in the translated play window is transmitted to the screen for display, wherein the screen displays the display image received by a receiving card.

A first device may receive a request to establish a replication session between a second device and a third device, where the replication session is associated with replicating user interactions with a user interface of an application across a first instance and a second instance of the application. The first device may receive, after receiving the request, information identifying a set of interactions by a user of the second device with a first user interface provided for display by the first instance. The first device may determine, from the information, a set of instructions related to causing an indication for the set of interactions to be provided for display on a second user interface provided for display for the second instance based on the information being received from the second device. The first device may provide, after determining the set of instructions, the set of instructions to the third device.

Systems and methods of use are presented that resize a displayed program presentation based on a requested television size, which allows a single large display monitor (television) to act as a proxy of all the smaller television sizes available in a given model line of televisions. The resized program is presented on the display monitor with a physical size larger than the requested size. Pricing information for the requested television size is superimposed on the presented resized program. Outlines for intermediate sizes of televisions of the same make and model to that of the display monitor are also presented in the presented program, including size and price indicators for the intermediate sizes. Multiple display monitors, each having a separate media player, can be implemented in a retail environment so as to allow several makes and models to be compared. Sync signals keep video transmitted by the media players synchronized.

A method of controlling a display device includes starting, by a first wireless communicator, first near field wireless communication with induced electricity, receiving configuration information using the first near field wireless communication, starting second near field wireless communication with another display device via a second wireless communicator based on the induced electricity, and transmitting the configuration information using the second near field wireless communication.

Provided are a display device and an operating method therefor. The display device include a user input interface configured to receive a signal from a remote control device, a wireless communication interface configured to receive image data from an external device and control data of the external device, a display configured to output a screen of the external device by using the received image data, and a controller configured to control the display to change a pointer display mode of the remote control device based on the control data of the external device received while outputting the screen of the external device.

Provided is a display device including: left and right displays that are spaced apart from each other; left and right lens groups respectively located at the rear of the left display and the rear of the right display; left and right display housings configured to surround the left and right displays and the left and right lens groups; a main frame provided between the left and right display housings; a connection structure capable of adjusting an angle between the main frame and a connector electrically connected to an external electronic device; and electronic components provided inside the main frame.

PWM-frame rate misalignment is mitigated through implementation of a discrete variable refresh rate (VRR) scheme. A target frame rate is limited to a frame rate selected from only those frame rates that facilitate alignment of each frame period to a specified edge of a PWM cycle of a brightness control signal of a display panel. This alignment results in each frame period at the selected frame rate starting at a same point in a corresponding PWM cycle and ending at a same point in a corresponding PWM cycle to help ensure a constant effective duty cycle across each successive frame period, which in turn mitigates perception of flicker that otherwise would arise. Further, the discrete VRR scheme can employ a compensation mode for compensating for the delay in rendering or otherwise obtaining a frame for display so as to maintain a consistent duty cycle in the brightness control signal.

An electronic apparatus and method of controlling same are provided. The electronic apparatus includes a sensor, a display, a memory configured to store module map information in which identification information of a plurality of display modules included in a display panel and location information of the plurality of display modules is mapped, respectively, and a processor configured to, based on scanned identification information corresponding to one of the plurality of display modules being received from the sensor, obtain location information of a display module corresponding to the received scanned identification information based on the module map information stored in the memory, and control the display to display the obtained location information of the display module.
