Following embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
Embodiment
As shown in Figure 1, be the synoptic diagram that the display of computing machine in the preferred embodiment of the present invention is connected with main frame.In computing machine 100, display 1 shows that through one cable (Display Cable) is connected with main frame 2, makes main frame 2 to send shows signal through this demonstration cable and gives display 1, shows content corresponding with control display 1.This demonstration cable can be; But be not limited to; Video Graphics Array cable (Video Graphics Array Cable, VGA Cable), digital visual interface cable (Digital Visual Interface Cable; DVI Cable) or HDMI cable (High Definition Multimedia Interface Cable, HDMI Cable).In addition; This display 1 is also through a USB (Universal Serial Bus Cable; USB) cable is connected to the USB interface of main frame 2 or is connected to the serial ports of main frame 2 through a serial interface cable line (Serial Cable), to realize the command transfer between display 1 and the main frame 2.
As shown in Figure 2, be the applied environment Organization Chart of the automatic adjustment system of display refresh rate of the present invention.This automatic adjustment system 10 is applied in the display 1.This automatic adjustment system 10 comprises enquiry module 101, judge module 102 and module 103 is set.In the present embodiment; This automatic adjustment system 10 is stored in the storage medium 11 of display 1 or is solidificated in the firmware of display 1 (Firmware); Carry out the automatic adjustment of carrying out with the refresh rate of realizing utilizing among the present invention 10 pairs of displays 1 of this automatic adjustment system by microprocessor 12.
As shown in Figure 3, be the process flow diagram of the automatic adjusting method of display refresh rate of the present invention.Below in conjunction with this Fig. 3, said automatic adjustment system 10 is elaborated.
Step S01, when main frame 2 was gone up in display 1 connection, said enquiry module 101 sent querying command a to main frame 2, the refresh rate that is provided with in the inquiry main frame 2.Particularly, when display 1 receives the shows signal of main frame 2 transmissions, represent that promptly this display 1 has connected main frame 2.In the present embodiment, enquiry module 101 is sent to main frame 2 via the USB interface of main frame 2 with this querying command through said USB cable line, or via the serial ports of main frame 2 this querying command is sent to main frame 2 through said serial interface cable line.
Particularly; When main frame 2 receives said querying command; This main frame 2 is inquired about the refresh rate of being preserved in the storage system of this main frame 2 through the driver (Display Driver) of control display 1, then the refresh rate that inquires is returned to display 1 through said USB interface or serial ports.
Step S02, said judge module 102 receives the refresh rate that main frame 2 is inquired.Step S03, judge module 102 judge that this refresh rate that inquires is whether in the support scope of display 1.If this refresh rate is in the support scope of this display 1, execution in step S04 then.Otherwise, if this refresh rate is in the support scope of this display 1, process ends then.In general, the display of different size or brand, the scope of the refresh rate of being supported has nothing in common with each other.
Step S04, the said module 103 of being provided with is sent one order to main frame 2 is set, and main control system 2 is provided with the refresh rate that display 1 is reset in order according to this.Particularly, this is provided with order and is sent to main frame 2 through said USB cable line via the USB interface of main frame 2 equally, or is sent to this main frame 2 through said serial interface cable line via the serial ports of main frame 2.This is provided with and comprises a preset refresh rate in the order, is set to this preset refresh rate with the refresh rate of main control system 2 these displays 1.The scope of the refresh rate that refresh rate that should be preset can be supported according to display 1 is provided with in advance.For example, if the refresh rate supported of this display 1 is between 60Hz to 90Hz, this preset refresh rate can be set to 75Hz.
When main frame 2 receives said when order is set; Said driver is set to this preset refresh rate according to the refresh rate of said preset refresh rate display 1; And be kept in the storage system of main frame 2, thereby make this display 1 under this preset refresh rate, to work normally.In addition, if the refresh rate that the user need adjust this display 1 during for other value, can be provided with by manual operational computations machine 100 under the prerequisite of display 1 ability operate as normal.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and the scope of technical scheme of the present invention.
