Signal timings
•  All are compliant only with non-interlaced.
• Frequencies for Power Macintosh and the Sun Ultra series are ref-
erence values.
• If the monitor is receiving timing signals that are not compatible,
[OUT OF TIMING] will appear. Follow your computer's instruction
manual to set the timing to be is compatible with the monitor.
• If the monitor is not receiving any signal (synch signal), [NO SIG-
NAL] will appear.
The connector pin
Power management
The monitor is based on the VESA DPMS.
To activate the monitor's Power Management function, both the video
card and the computer must conform to the VESA DPMS standard. 
DPMS: Display Power Management Signalling
DDC (Plug & Play)
This monitor supports the VESA DDC (Display Data Channel) stan-
dard.
DDC is a signal standard for carrying out Plug & Play functions on the
monitor or PC. It transfers information such as degree of resolution
between the monitor and PC. You can use this function if your PC is
DDC compliant and if it is set so that it can detect the Plug & Play
monitor.
There are many varieties of DDC due to the differences between sys-
tems. This monitor works with DDC1 and DDC2B.
