multimedia monitor computer

The new monitors are designed to encourage the use of multimedia PC, but not it is always easy to understand the function of all the buttons and the various connections .

cable tvThe main features of the monitor, the to help you locate the right product are suitable for your needs : size, the resolution and brightness . The screen size is expressed in inches (1 inch is equal to 2.54 centimeters) and is a measure the diagonal of the screen. The resolution is constituted by the number of points on the screen that contribute to display the image, and is expressed in dots of color ( called pixels ) per inch. The higher the number of points for every inch the sharper the image . Another factor to take into account , with regard to the resolution , is the distance in millimeters between two pixels : in English “dot picth .”

Obviously, the more this value is low, the higher the resolution that can be set on the monitor. Finally, the brightness (measured in lumens , abbreviated lm) indicates the intensity of light that the monitor can reproduce for a given unit of area .
Ignition switch allows you to turn on and turn off the monitor . usually the key is more visible and accessible.

This menu allows you to display the menu with all the options you can adjust the monitor such as : the contrast and brightness . Navigation buttons are needed for move within the menu control the monitor.

This AUTO key is present only on the screens LCD. Used when the automatic tune the image does not funziona.Per example, if after connecting to another computer, the pictures are not perfectly tuned you can try with the Auto button. Swivel base is the structure that holds the screen, must have two fundamental characteristics: be particularly robust and Fast and powerful HD video editing, including 3Deasily adjustable according to the needs of the user. beware because LCD screens aesthetically very interesting are not always without problems. We must report that there are currently in circulation also monitors that can rotate vertically . This type of screens are suitable for display photos, for typesetting texts arranged vertically or to manage architectural projects . Audio input left, right and video These jacks allow you to connect external devices to the monitor such as DVD players, VCRs or console. The use of this type of revenue is less practical than other systems (for example, the S-Video) and of lower quality. When connecting to these jacks old peripherals however, may represent the only solution. Entrance

Configure the color of the Monitor


S-Video ( Super Video ) The S-Video format is a format with higher quality than VHS , because unlike the latter where the color information and brightness “Travel ” together, in systems such as the S -Video information of brightness and color are kept separate. In this port insert the S-Video cable from a computer , a reader DVD , or a video camera . This entry allows to see the images reproduced from an external device to the monitor in the most semplice.A Unlike the SCART S-Video jack used to connect computers. SCART Not all monitors have this port link. You can find it instead integrated into all newer televisions .

SCART is equipped with 21 PIN ( on ​​the base or the metal contacts of a connector) to the connection of audio devices / video.Per example : VCRs, receivers , DVD players, cable boxes and TVs . Through SCART cables can pass signals video ( a low-quality video format in which signals of light and color are combined ) , RGB or Super VHS .

IN DVI (Digital Visual Interface) An input port data format digitale.È usually used for high- definition of a video signal from from a computer or a video projector. You can find this out in many the latest generation of video cards . Its use leads to a considerable improvement compared with analog interfaces. The images reproduced through a DVI connector are very sharp , and the monitor that has this connector is designed HDTV ( high definition TV ) .

Past and future We can divide the monitor market into two large families according to the type of technology used : CRT (Cathode Ray Tube ) or LCD (Liquid Crystal Display) . The acronym CRT indicates a screen that uses a cathode ray tube, traditionally used in TVs. Through the tube , the cathode ray are conveyed on a sensitive surface which is able to reconstruct the image . CRT monitors usually have a 4:3 ratio between length and height. An LCD monitor instead provides a screen liquid crystal display ( such as that used by us as an example) and is thinner and lighter than CRTs. LCD technology was used initially in the calculators and portable computers. An LCD is internally composed of a liquid trapped in numerous cells.

Each cell is provided with electrical contacts and is contained within two screens polarized along the same axis . The images on an LCD screen are visible only from angles up to 120 or 160 degrees. But the crystal monitor liquids produce less heat than CRTs , use less energy , can be rotated in a vertical position , presenting a flat screen without distortion and spherical . They also , a reduced thickness and generally a relationship (width / height) of 16:9 which is perfect for viewing movies and DVDs . To meet the growing media needs User , engineers have built into the monitor a greater number inputs to allow viewing of images from a TV tuner, or from a DVD player .
