Working with the notebookLCD screenLCDscreenNotesHigh-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. Fortechnical reasons, TFT monitors are manufactured for a specific resolution. An optimal, clearpicture can only be ensured with the correct resolution intended for the relevant TFT monitor. Amonitor resolution which differs from the specification can result in an unclear picture.The screen resolution of the LCD monitor of your notebook is optimally set at the factory.The standard of production techniques today cannot guarantee an absolutely fault-free screendisplay. A few isolated constant lit or unlit pixels (picture elements) may be present. The maximumpermitted number of pixels faults is stipulated in the international standard ISO 9241-3 (Class II).Example:A monitor with a resolution of 1280 x 800 has 1280 x 800 = 1024000 pixels. Each pixel consists ofthree subpixels (red, green and blue), so there are almost 3 million subpixels in total. According toISO 9241-3 (class II), a maximum of 2 light and 2 dark pixels and an additional 5 light or 10 darksubpixels or a corresponding mix may be defective (1 light subpixel counts as 2 dark subpixels).Pixel A pixel consists of 3 subpixels, normally red, green andblue. A pixel is the smallest element that can be generatedby complete functionality of the display.Subpixel A subpixel is a separately addressable internal structurewithin a pixel that enhances the pixel function.Cluster A cluster contains two or more defective pixels orsubpixels in a 5 x 5 pixel block.Background lightingTFT monitors are operated with background lighting. The luminosity of the backgroundlighting can decrease during the period of use of the notebook. However, you canset the brightness of your monitor individually.Synchronising the display on the LCD screen and an external monitorFor more information, please refer to the chapter "Key combinations", Page 43under "Display output, switch between".Ambient Light SensorIf your notebook was shipped with the Windows 7 operating system, the screen brightness isregulated by means of the Ambient Light Sensor and depending on the respective light conditions.This results in optimum readability and longer battery life at the same time.Using a device as a tablet PCYou can execute commands as follows:• using the stylus pen (supplied with your device).• using your finger (only with Dual Digitizer technology).Fujitsu Technology Solutions 31
