How to measure the size of an LCD monitor, how to write the detailed calculation formula!

The length and width of the LCD monitor is calculated: 10: 121 inches = cm (all LCDs are in inches, Chinese are used to calling them 'inches').

Let's say your LCD is 17 inches, and its 17 inches is diagonally long.

Length square + width square = 17 square.

If it is a standard screen, then the aspect ratio is 4:3

If it's widescreen, the aspect ratio is 16:9

Using the above data, the length and width can be calculated using the Pythagorean theorem.

The standard screen is inches long and inches wide.

16:9 Widescreen Long inch Wide inch.

19 inches: viewing area (mm) width x height) square millimeters 19 inches widescreen:

Viewable area (mm) W) x H) Square mm 20 inch Widescreen:

Viewable area (mm) W) x H) Square mm 20 inch Widescreen:

Viewable area (mm) W) x H) mm² 24" Widescreen:

Viewable area (mm) width x height) square millimeters.

The size of a CRT monitor refers to the diagonal size of the CRT. The maximum viewing area is the maximum range of graphics that can be displayed on the display. The size of the CRT is usually measured in the length of the diagonal line, in inches (1 inch =, the common ones are 15 inches, 17 inches, 19 inches, 20 inches, etc.).

The display area will be smaller than the size of the display tube. The display area is expressed as the product of length and height, and usually the diagonal length of the visible part of the screen. The viewing range of a 15-inch monitor is about inches, the viewing area of a 17-inch monitor is mostly between 15 and 16 inches, and the viewing area of a 19-inch monitor reaches about 18 inches.

The dimensions are measured diagonally, one inch =

No software can easily quantify the response time of the LCD you are using, as well as the contrast, lumens, and so on.

When choosing an LCD monitor, if it is a home machine, it is best to choose it with the purpose of practical application, and do not have to focus on various parameters. The so-called 2ms grayscale response time, 1700:1 contrast ratio and other exaggerated parameters on the market, but what is the six primary colors, double speed reproduction, as a buyer, or cover your pocket is the most important.

Don't let the merchant use some vague means to take away our silver.

As far as the current LCD panel technology is concerned, there is definitely still a gap in the professional field, but ordinary household use, it should be fully competent. Color, 300 lumens, 500:1 contrast ratio, 16ms response time, such as this can be said to be the most basic parameter grade on the market, has been fully qualified for movies, games and office requirements.

As for the discrepancies between some of the physical objects and advertisements that you are worried about, as long as you exclude some rogue brands, such as Shenzhou, you can basically avoid it, of course, those merchants use vague concept parameters, in fact, they don't look at it. The most practical thing is to choose it yourself with glasses, and then pay if you are satisfied.

In addition, it is recommended to test the software of the LCD screen, DisplayX, which is only 18K. Tests that can basically meet the general needs, including the response time (as low as 16ms). Actually,Don't worry too much about the shadow problem,The screen that is obviously dragged on the market has basically disappeared。

As for lumens and contrast, apply the grayscale test of the test software as well as the color test, and take a look at it.

Search Display size A lot of searches, there are calculation methods in the encyclopedia, do you still need to ask for help?

1. The diagonal length of the display, unit: inches. Narrow screens are usually divided into narrow screens and widescreens. Length: Width = 4:3. Widescreen is the length that has been popular in the last two years: width = 16: 9.

2. Conversion of units of measurement: 1 cm = inch (or 1 inch = cm), for example, 64 cm TV is 25 inches. In the technical parameter standard of CRT color television, the size of the TV refers to the diagonal size of CRT glass.

Due to the thicker corners of the glass, the diagonal length of the actual visible image allows for a certain amount of elastic space, such as a 54 cm (21 in) size display, and the diagonal of the visible image only needs to be greater than or equal to 51 cm. Meets standards.

3. Usually, the diagonal size of the flat-screen TV screen is basically equal to the effective visible image size, but some companies also count the black border around the size, so there is a gap between the dimension and the effective visual image size.

Currently, flat-screen TVs come in a lot of sizes, which is also confusing. Unlike CRT color TVs, it doesn't have a specific size. When people buy, they can measure the size of the visible image (inside the box) with a ruler.

Measure the diagonal length of the display, and then convert it to inches (1 inch = how many inches of the screen refers to the length of the diagonal of the screen, and the unit used is inches.)

For example, the diagonal length of the 19-inch display is about 48 cm.

4:3 inch wide and 19-inch screen high.

16:9 inch wide screen in inches high at 19:19.

You can use a ruler to measure the diagonal length of the screen, and if the unit of measurement is centimeters, then divide by how many inches the data gets. If the diagonal of the same channel length has different proportions, then the width of the screen and the height of the screen will be different.

You can use a ruler to measure the diagonal length of the screen, and if the unit of measurement is centimeters, then divide by how many inches the data gets. If the diagonal of the same channel length has different proportions, then the width of the screen and the height of the screen will be different.

The way to calculate the screen inch: divide the length of the diagonal by centimeters (1 inch = centimeter) such as a mobile phone with a 7-inch screen, centimeter) x 7 (inches) = centimeters), this is the length of the screen diagonal; The reverse is also true, with centimeters) centimeters) = 7 (inches), when measuring with a ruler, there may be errors, but never large, all within the decimal point.

However, due to the fact that the display has a variety of length-to-width ratios, such as the common :9 and so on, it will also cause two displays of the same inch to have unequal lengths and widths.

How to measure how many inches of TV, how to calculate inches.

The distance of the diagonal of the screen - inches=

1 inch = centimeter.

A 7-inch tablet is centimeters!

Centimeters are the diagonal length of the tablet screen!

It doesn't matter if the screen is ten inches and the size of the tablet!

The size of the tablet is definitely larger than the screen!

How much is the merchant decides by himself!

is the diagonal distance of the viewable area of the display.

The distance of the diagonal of the screen - inches=

Display size refers to the distance from the diagonal of the screen.

1. The size of the CRT monitor refers to the diagonal size of the picture tube. The maximum viewing area is the maximum range of graphics that can be displayed on the display. The size of the CRT is usually measured in the length of the diagonal line, in inches (1 inch =, the common ones are 15 inches, 17 inches, 19 inches, 20 inches, 24 inches, etc.

2. The size of the CRT monitor refers to the diagonal size of the CRT. The maximum viewing area is the maximum range of graphics that can be displayed on the display. The size of the CRT is usually measured in the diagonal length of the mountain and is measured in inches (1 inch =, the common ones are 15 inches, 17 inches, 19 inches, 20 inches, etc.).

The display area will be smaller than the size of the display tube.

3. The display area is represented by the product of length and height, and usually people also use the diagonal length of the visible part of the screen. The viewing range of the 15-inch monitor is about 18 inches, the viewing area of the 17-inch monitor is mostly between 15 and 16 inches, and the viewing area of the 19-inch monitor reaches about 18 inches.
