1 – 2
Relevant signal timings (analog)
•  Recommended resolution is 1280 
u
 1024.
•  All are compliant only with non-interlaced.
•  Frequencies for Power Macintosh and the Sun Ultra series are refer-
ence 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 SIGNAL]
will appear.
Relevant signal timings (digital)
•  Recommended resolution is 1280 
u
 1024.
•  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 SXGA output capability can be connected
here. 
(Depending on the type of computer to be connected, the display may
not work correctly.)
•  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.
