•  All are compliant only with non-interlaced.
•  Frequencies for Power Macintosh are reference values. To connect,
another adapter (purchased separately) may be required.
• 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 so that it is compatible with the monitor.
• If the monitor is not receiving any signal (synch signal), [NO SIG-
NAL] will appear.
Relevant signal timings (digital)
•  All are compliant only with non-interlaced.
•  A computer with an output terminal conforming to DVI (DVI-D24 pin
or DVI-I29 pin) and with XGA output capability can be connected
here. Depending on the type of computer to be connected, the dis-
play may not work correctly. In order to connect, it is necessary to
purchase a digital signal cable (model name: NL-C01E) separately.
• 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 so that it is compatible with the monitor.
• If the monitor is not receiving any signal (synch signal), [NO SIG-
NAL] will appear.

Power management
The monitor is based on the VESA DPMS and the DVI DMPM stan-
dards.
To activate the monitor’s Power Management function, both the video
card and the computer must conform to the VESA DPMS standard
and the DVI DMPM standard.
DPMS: Display Power Management Signalling
DMPM: Digital Monitor Power Management
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.
