A monitor is a piece of computer hardware that is used to display information to the user. It is usually connected to the computer via a video cable. The most common type of monitor is the Cathode Ray Tube (CRT) monitor. This type of monitor uses a beam of electrons to create an image on the screen. LCD monitors are also common. These use a liquid crystal display to create an image on the screen. LED monitors are the newest type of monitor. These use light-emitting diodes to create an image on the screen.
Monitors come in a variety of sizes. The size is measured in inches diagonally from corner to corner. Common sizes include 15″, 17″, 19″, and 21″. The resolution of the monitor is the number of pixels that can be displayed on the screen. The higher the resolution, the sharper the image will be. Resolution is measured in pixels per inch (ppi).
Most monitors can display images in both standard and widescreen formats. Standard format is 4:3 and widescreen is 16:9. Widescreen monitors are becoming more popular as more movies and videos are being produced in widescreen format. Many monitors can also display high-definition images. These monitors have a resolution of 1080p or higher.
Monitors are an important part of any computer system. They provide a way for the user to see what is happening on the computer. Without a monitor, a computer would be much less useful.
