Developed by the Video Electronics Standards Association(VESA). When used in a PC running Low Radiation Compliance (MPR II) This monitor meets of the strictest one guidelines available today for low radiation emissions, offering the user extra shielding and an antistatic screen coating. These guidelines, set forth by a government agency in Sweden, limits the amount of emission allowed in the Extremely Low Frequency (ELF) and Very Low Frequency (VLF) electromagnetic range. DDC (Display DDC is a Data Channel) communication automatically informs the host channel over system(PC) which about its the monitor capabilities.This monitor has three DDC function; DDC2B carry out uni-directional communication between PC and monitor.
