Embodiment Construction

[0013] Such as figure 1 Shown is an application environment diagram of a preferred embodiment of the refresh rate control system of the present invention. In this embodiment, the refresh rate control system 10 runs in the host 1, and the host 1 is connected to the display 2 and the input device 3 respectively. The host 1 also includes a storage unit 11 for storing specific information. The refresh rate control system 10 is used to obtain the refresh rate supported by the display 2 when the information input by the input device 3 is the same as the specific information in the storage unit 11, and when the refresh rate input by the user is higher than the refresh rate supported by the display 2 When within the range, the refresh rate input by the user is updated to the refresh rate of the host 1 system. The host 1 can be a desktop computer (PC), a notebook computer (Notebook), a server (Server) and other electronic computing devices. The input device 3 can be an ordinary keyb...

Abstract

The invention discloses a refresh rate control method. The method is applied to a host machine and comprises the following steps of: when the host machine is started, detecting whether the host machine receives information input by an input device; when the host machine receives the information input by the input device, judging whether the input information is the same as specific information stored in a storage unit of the host machine; when the information input by a user is the same as the specific information in the storage unit, setting a refresh rate of a host machine system to be a default value which is supported by all displays; acquiring a refresh rate range which is supported by the displays; receiving a refresh rate input by the user, and judging whether the refresh rate input by the user is effective according to the refresh rate range which is supported by the displays; and when the refresh rate input by the user is effective, updating the refresh rate input by the user to be the refresh rate of the host machine system. The invention also provides a refresh rate control system.

Description

technical field [0001] The invention relates to a refresh rate control system and method. Background technique [0002] When the monitor needs to be replaced due to monitor failure or other reasons, if the refresh rate supported by the new monitor is too low to reach the original refresh rate of the host system, the new monitor will have a black screen when the host enters the operating system, making it impossible for the user to change the host system’s refresh rate. set up. Generally speaking, the solutions to this problem are: 1. Change to a monitor that supports high refresh rate. When the host enters the system, lower the refresh rate of the host system, and then replace it with a monitor with a lower refresh rate; 2. Enter the safe mode of the host system to uninstall the graphics card driver and restart the host system. At this time, the refresh rate of the host system is the default 60Hz (the refresh rate supported by all monitors), and then replace it with a new m...
