- Recommended resolution is 1280 x 1024.
- All are compliant only with non-interlaced.
- Frequencies for Power Macintosh and Sun Ultra

series are reference values. To connect, another
adapter (commercially available) 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 SIGNAL] will appear.

The monitor is based on VESA DPMS (Display
Power Management Signaling).
To activate the monitor's Power Management
function, both the video card and the computer
must conform to the VESA DPMS standard.

This monitor supports the VESA DDC (Display
Data Channel) standard.
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 systems. This monitor works
with DDC1 and DDC2B.
