Relevant signal timings
• Recommended resolution for LL-T1520 is 1024 x 768. 
• Recommended resolution for LL-T1620 is 1280 x 1024. 
• All are compliant only with non-interlaced. 
• The monitor can be connected to the following computers that have a
DVI standard output terminal  (DVI-D24 pin or DVI-I29 pin) for digital
connection. (Note that the display may not appear correctly, depend-
ing on the connected computer.)
-- LL-T1520: Computers capable of XGA output
-- LL-T1620: Computers capable of SXGA output
• Frequencies for Power Macintosh and the Sun Ultra series are refer-
ence 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.

Power management
The monitor is based on the VESA DPMS*
1
 and the DVI DMPM*
2
 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.
*1  DPMS: Display Power Management Signalling
*2  DMPM: Digital Monitor Power Management
DDC (Plug & Play)
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 mon-
itor.
There are many varieties of DDC due to the differences between sys-
tems. This monitor works with DDC1 and DDC2B.
PRODUCT DESCRIPTION
Adjusting the tilt and the swivel of monitor
Lightly holding both sides of the monitor, adjust it to a suitable viewing
angle.
Note: When adjusting the screen tilt and swivel, pressure from hands
on the LCD panel could cause damage.
