    computer and Internet have changed and change the world. The team is the vehicle that the world to introduce technological advances and medical and social services. Computer screens are the windows of this new world and continue to improve in quality and performance. The computer monitor was ten years ago is not the same visual unit is now, but it’s still a piece of electrical equipment, a wide range of images from the video output can be viewed from different computers, without requiring a permanent record. The display device is used to display images is now a thin film transistor liquid crystal as a TFT-LCDs known. Older monitors use a CRT or cathode ray tube.

    Measurement of computer monitors is a little confusing. The measurement method is based on the CRT TVs, which are used when the image was based around popular tubes.

    you were circular, so you just need a diameter measurement to describe the size of the pipe. If cathode ray tubes are in the form of rectangles made this method is still used, so that the distance between two opposite corners of the screen size is specified, although it is not about differences aspect ratios of monitors with the diagonal. The form of a diagonal area decreases when it is less space, so that a measuring system is not exact, monitored for square inch for the same size diagonally. Another problem with the screen size of the pixels, which are distorted by the campaigns will be. Visible size is more important than the measurement of the size of the pixels, which can be hidden behind the cover of the housing.

    Imaging technology continues to improve. TFT-LCD monitors are becoming more popular, the old passive LCD has a slow response time and contrast was poor. They began to be replaced mid-1990th Other types of visual displays include Penetron and plasma screen, together with the old CRT.

    The LCD is light, compact and robust, and there is no geometric distortion, but has a low contrast, uneven backlight, causing slow response times, the ghost images. The Military Aircraft Penetron screen has a high contrast ratio and is extremely strong, although there are only four color screens. Plasma also has high contrast ratios and a high-speed performance, superior color and black and low, but has lower resolution on a big screen and there is a noticeable flicker when the screen is near.

    The computer monitors today an infinite number of colors represented by the continuous change of the intensities in the RGB color space, which indicates the analog red, green and blue video signals. New connectors replace both analog and digital signals with digital video signals having only integrated data and video connections. Other new features include multi-monitor functions, the identical image and extension reflex called monitoring, which shows different images can be displayed, but requires additional hardware and software. There is no doubt that computer monitors will continue to improve in quality and functionality. Touch screen technology is opening the door to another big step in the virtual screen industry.
