CCTV ² monitors are cathode ray tube designed for continuous operation. Application for displaying a still image on the TV with video input ends phosphor burn and destroy the TV. Monitor is a device allowing conversion of electrical signal to optical signal that is suitable for the human senses. Monitor should meet safety standards means the need to have known. B. The sign shall specify, inter alia, safety standards maximum emission levels of electromagnetic radiation, X-ray, as well as user-level security and protection against electrical equipment against voltage surges coming from the electricity grid. Selecting the monitor must necessarily pay attention to the utility parameters: the resolution - the ability to reproduce detail, correct play of shapes, image stability. Resolution is usually given in a number of lines, and so monitors are high resolution color for over 400 TV lines and monochrome for 1000 Note, however, that this resolution has no relation to the number of lines of force in the standard D / K or B / G. This parameter is even loosely associated with the resolution, rather it is an estimate of the capacity to transmit information about color or gray levels in conjunction with the resolution. It happens that the resolution is quoted.
