Low Radiation Compliance (MPR II)
This monitor meets one of the strictest guidelines available today for
low radiation emissions, offering the user extra shielding and an anti-
static screen coating. These guidelines, set forth by a government
agency in Sweden, limit the amount of emission allowed in the
Extremely Low Frequency (ELF) and Very Low Frequency (VLF)
electromagnetic range.
Self Diagnostics
This monitor can sense when there is a possible problem present,
and informs you of this condition by presenting you with a SELF
DIAGNOSTICS OSD. This OSD may pop up when it is On but no
signal is detected. In this case the message NO SIGNAL DETECTED
will be high lighted, alerting you to check the signal cable
connections.
DDC (Display Data Channel)
DDC is a communication channel over which the monitor
automatically informs the host system (PC) about its capabilities.This
monitor has DDC function; DDC2B carry out uni-directional
communication between the PC and the monitor. Under these
situations, the PC sends display data to the monitor but not
commands to control the monitor settings.
NOTE : PC must support DDC functions to do this.
Some older computer systems are not compatible with the
DDC standard. If your monitor is displaying a monochrome
image or the wrong resolution, need to change with a DDC
compatible VGA card.
