Abstract

The display capable of simultaneously connecting with computer and cursor control device includes display screen, screen image setting control unit, display control unit and output-input control unit electrically connected with display control unit. When the screen image setting starting instruction is detected by cursor control device, the display control unit starts the screen image setting control unit to display the screen image setting picture on the display screen and stop signal input in computer, then the display control unit transfers the input signal to control unit to make the cursor control device control the operation of the screen image setting control device.

Description

technical field [0001] The invention relates to a computer monitor, in particular to a monitor which can be connected to a computer and a cursor control device at the same time. Background technique [0002] Existing monitors connected to computers, such as traditional desktop monitors and liquid crystal displays (LCDs), are provided with several display control buttons on the housing of the monitor to adjust and correct the image displayed on the monitor. Although the functions of the display control buttons of different monitors are similar, their operation methods are often very different, so users often cannot make good use of them because they are not familiar with the operation. In addition, the setting of these display control buttons often makes the mechanical design of the display very complicated and it is not easy to reduce the cost. [0003] In addition to directly using the display control buttons on the monitor casing to adjust the image screen, the monitor co...
