The maximum resolution of the display indicates the number of colour points (pixels) on the computer screen. The higher the resolution the better quality (more detailed) image. For example, 1366x768px means that your computer has 1366 points horizontally x 768 points vertically. High resolution provides more information on the screen and this is directly related to the size of the screen. Nowadays even a 12.1 inches screen can have 1024x768 resolution. At the first glance it looks that this resolution is too high for this size of the screen, however, high resolution provides more comfort.
