Description

A method of control a parameter of a monitor

The present invention relates to a method for adjusting a parameter of a monitor, and more particularly, to a method for adjusting a parameter of a monitor adapted to adjust various parameters of the monitor by software of a PC main body when a mode is changed.

In general, a monitor refers to an output device of an information processing device that converts a binary data signal of an information processing device into an image signal by using a cathode ray tube and outputs it to a screen.

The monitor may be classified as shown in Table 1 according to the type of video card.

Classification by video mode Video mode Horizontal frequency (kHz) Vertical frequency (Hz) Resolution (H * V) CGA 15.75 60 640 * 200 EGA 21.8 60 640 * 350 VGA 31.5 60/70 720 * 350 640 * 480 SVGA 35 to 37 INTERLACE 1024 * 768 800 * 600 High resolution mode 48-75 60-70 1024 * 7681280 * 1024

As shown in Table 1, horizontal and vertical frequencies differ according to the modes supported by the video card, and in particular, a video card supporting various modes, for example, a video card supporting VGA and SVGA and high resolution only modes, is mounted on the monitor. If so, the range of the horizontal frequency of each mode is about 30 to 75 KHz.

Therefore, a multi-mode monitor that can switch modes according to various vertical and horizontal synchronization signals is required. Multi-mode monitors that allow one monitor to operate according to various graphics modes of a computer system are required for vertical synchronization and horizontal synchronization signals. The polarity of the synchronization signal is detected and converted to be suitable for operation.

1 is a perspective view of a general monitor, and FIG. 2 is a circuit diagram showing a general parameter adjusting device.

As shown in FIG. 2, in the multi-mode monitor, parameter adjustment is mostly controlled by the microcomputer 20, that is, the microcomputer 20 is controlled by the operator for each parameter, for example, horizontal position, horizontal size, vertical position, and vertical size. , Pincushion, tilt, etc. are selected through the key input unit 10 to output a digital / analog conversion value related to the corresponding parameter.

In this case, as shown in FIG. 1, the key input unit 10 is normally mounted at the lower end of the monitor. The menu key (# 1), the level-up key (# 2), and the level-down key (# 3) are selected. Key # 4, volume adjustment key (# 5: also used as ESC key), and the like.

For example, if the menu key (# 1) is selected by the operator, ) Is applied to the microcomputer 20.

Accordingly, the microcomputer 20 determines that the menu key # 1 is operated, drives the OSD IC 30 to output a text signal to the video amplifier 40 to display a menu on the CRT 50.

When the operator monitors the displayed menu and selects a parameter to be adjusted with the selection key (# 4), ( ) The voltage is applied to the microcomputer 20, and the microcomputer 20 recognizes this.

The level-up key # 2, the level-down key # 2, # 3, and the volume key # 5 are also sensed by the microcomputer 20 in the same manner.

That is, in the conventional multi-mode monitor, the microcomputer 20 adjusts each parameter and outputs it to the corresponding monitor circuit according to a key input operated by the operator, and outputs a light emitting diode (LED) or an on screen display (OSD). Since it is to display through, there was a problem that not only the parameter adjustment is cumbersome but also takes a lot of adjustment time.

Accordingly, an object of the present invention is to provide a method for adjusting a parameter of a monitor, which is designed to adjust various parameters of the monitor by software of a PC main body when a mode is changed.

The parameter adjusting method of the monitor according to the present invention for achieving the above object comprises: a main body microcomputer for performing a predetermined program according to the key input content operated by the operator; A personal computer equipped with a monitor micom that receives data from the main body microcomputer and executes a predetermined program through a D-SUB connector, wherein the main body microcomputer determines whether a parameter adjustment command is authorized from an operator through key input. Wow ; Outputting data for displaying the parameter adjustment screen to the monitor micom, if the parameter adjustment command is applied as a result of the determination; The monitor micom receiving the data and displaying a parameter adjustment screen; Sensing, by the main body microcomputer, an operator's key input for parameter adjustment; Generating, by the main body micom, a corresponding parameter according to a key input content and transmitting the generated parameter to a monitor micom; And receiving, by the monitor micom, the parameter and supplying the parameter to the corresponding monitor circuit.
