What's the use of screen resolution?

screen resolution refers to the clarity of text and images displayed on the screen. The higher the resolution (such as 16 x 12 pixels), the clearer the project. At the same time, the smaller the items on the screen, the more items the screen can hold. The lower the resolution (for example, 8 x 6 pixels), the fewer items are displayed on the screen, but the larger the size. The resolution that can be used depends on the resolution supported by the monitor. CRT monitors usually display a resolution of 8 × 6 or 124 × 768 pixels, and it may be better to use other resolutions. LCD monitors (also known as flat panel monitors) and portable computer screens usually support higher resolution and work best at a certain resolution. The larger the monitor, the higher the resolution usually supported. Whether the screen resolution can be increased depends on the size and function of the monitor and the type of video card.
