What does auto mean on the monitor

In monitors, auto means "automatic" and is a button used to automatically correct the display position on the screen, that is, the automatic adjustment key. The function of AUTO is to automatically calculate the ideal value of image color temperature, horizontal and vertical position, pixel frequency and phase, adjust the best picture, solve the problem of picture confusion when performing different communications, and adjust the display to the best display state.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The "AUTO" button on the computer screen and monitor is a button used to automatically calibrate the position of the screen display. AUTO means automatic. The AUTO button on the monitor is an automatic adjustment button (automatic calibration screen display button).

If the computer screen is not centered, distorted, or unclear, just press the AUTO button and it will automatically adjust to the normal state.

The function of AUTO is to automatically adjust the display to the best display state, including automatically adjusting resolution, contrast, brightness and other parameters. Eliminate the hassle of manual adjustments.

The automatic adjustment function will automatically calculate the image color temperature, horizontal and vertical position, pixel frequency and ideal phase value, adjust the best picture, solve the picture confusion that often occurs when performing different communications, and truly achieve "easy to use" ".

Commonly used button function description:

1. AUTO button: automatically adjust the monitor settings;

2. ECO button: monitor energy-saving mode button;

3 , MENU button: displays the display adjustment menu;

4. Plus and minus buttons: used to adjust menu options and option values ​​when the menu is displayed.

Extended knowledge:

The monitor is an I/O device belonging to the computer, that is, an input and output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. It can be divided into various types such as CRT and LCD.

Generally, when the humidity is maintained between 30% and 80%, the monitor can work normally. However, once the indoor humidity is higher than 80%, condensation will occur inside the monitor. The internal power transformer and other coils are prone to leakage after getting wet, and may even cause a short circuit; the high-voltage parts of the monitor are prone to discharge; the components inside the machine are prone to rust and corrosion, and in severe cases, the circuit The board has a short circuit.

The main technical parameters of computer monitors:

1. Viewing angle: The viewing angle of the LCD monitor is not necessarily symmetrical between the upper and lower sides, but it is symmetrical from left to right. When the incident light of the backlight passes through the polarizer, liquid crystal and alignment film, the output light has specific directional characteristics.

2. Point pitch: Generally, the viewing area of ​​a 14-inch LCD is 285.7 mm×214.3 mm, and the maximum resolution is 1024×768. The point pitch is equal to: visible width/horizontal pixels (or visible height/ vertical pixels).

3. Color degree: Any color in nature is composed of three basic colors: red, green and blue. The LCD panel is composed of 1024×768 pixels, and each individual pixel color is composed of red, Three basic color controls of green and blue (R, G, B).

4. Contrast value: The contrast value is the ratio that defines the maximum brightness value (full white) divided by the minimum brightness value (full black). CRT monitors often have contrast ratio values ​​as high as 500:1, so a truly black image can easily be rendered on a CRT monitor.

5. Brightness: The brightness of the LCD display is slightly lower, and the screen will also become darker. The maximum brightness of the LCD display is usually determined by a cold cathode ray tube (backlight). The brightness value is usually between 200 and 250cd/m2. between.

6. Response time: refers to the speed at which each pixel of the LCD monitor responds to the input signal. This can make the LCD monitor have a trailing feeling when displaying moving images. Of course, this value should be as small as possible. The smaller the better.
