How is monitor measured

The computer or the laptop manual will mention the monitor size. Manufacturers sometimes display it on a sticker on the device. Use a measuring tape of sufficient length.

Start at the top-left corner and extend it along the diagonal to the opposite bottom-right. If you start from the top-right corner, pull it straight to the bottom-left corner.

Measure only the screen and not the bezel or the casing around the screen. The diagonal measure is the screen size. An online search is the fastest way to find the precise size of the computer monitor.

Type the make of your computer monitor or laptop and any model number that tail them in a search engine, and you will get the detailed specifications with the screen size. The Pythagorean theorem is an alternative method to measure a computer monitor. It states in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

In a computer monitor, the hypotenuse is the diagonal measure that gives you the screen size. Calculate the square root of this sum to get the diagonal measurement and the screen size. For instance, a Dell XPS 13 has a screen width of Multiply the width by itself to get Then multiply the height by itself to get Add the two numbers together There are online calculators like Omni Calculator that quickly estimate the dimensions with the diagonal, width, or height.

Enter one, and it will automatically calculate the other two measurements. Actively scan device characteristics for identification. Use precise geolocation data. Be sure to only measure the screen; do not include the bezel the plastic edge around the screen. The model number of the monitor includes the size of the monitor in it. For example, an Acer inch screen could have a model number of SHL.

The "20" after the "S" is the size of the monitor, in this case, 20 inches. In general, a model number starts with one or two letters, followed by numbers. The first two numbers after the letters usually represent the size of the monitor. If you're still unsure, a quick online search of the model number provides you the exact size. The size of a laptop computer monitor is determined by physically measuring the screen.

The specifications for a laptop include the size of the laptop screen. For LCD monitors, screen size is measured diagonally from the inside of the beveled edge.

The measurement does not include the casing as indicated in the image below. For a more accurate representation of a CRT's size, find out its viewable screen size. This is the measurement of a CRT display without its outside casing. Notebook screen sizes are smaller, typically ranging from 12 to 17 inches.

As technologies improve in both desktop and notebook displays, even larger screen sizes are becoming available. For professional applications, such as medical imaging or public information displays, some LCD monitors are 40 inches or larger!

Obviously, the size of the display directly affects resolution. The same pixel resolution is sharper on a smaller monitor and fuzzier on a larger monitor because the same number of pixels is spread out over a larger number of inches. An image on a inch monitor with an x resolution will not appear nearly as sharp as it would on a inch display at x If you have been around computers for more than a decade, then you probably remember when NEC announced the MultiSync monitor.

Up to that point, most monitors only understood one frequency, which meant that the monitor operated at a single fixed resolution and refresh rate. You had to match your monitor with a graphics adapter that provided that exact signal or it wouldn't work.
