Nowadays even a 12.1 inches screen can have 1024x768 resolution. High resolution provides more information on the screen and this is directly related to the size of the screen.

For example, 1366x768px means that your computer has 1366 points horizontally x 768 points vertically. The higher the resolution the better quality (more detailed) image. The maximum resolution of the display indicates the number of colour points (pixels) on the computer screen. However, it has to be considered that a bigger screen means a bigger size and usually also a bigger weight of the computer, besides it can be damaged more easily during opening and closing. A bigger monitor is usually required for editing graphics or reviewing big-size tables, etc. Portable computers that are positioned as a replacement of desktop computers sometimes have the screen as big as 17'. This option is very handy for reading or, for example, drawing when the keyboard is not required. These models are sometimes referred to as transformers or tablets - they can be used both as a standard portable computer and as a tablet computer. Some portable computers have the option of turning the screen to the angle of 180 degrees and close it with the keyboard – the result is a true tablet computer without a keyboard. The ultra compact category portable computers have the display size of about 10,1'. Average portable computers have 15.4' standard or 15.6' wide-screen displays. The display size describes the size of the visible part of the screen of your portable computer across the diagonal in inches.
