Recommended Use

For optimum performance, please note the following when

setting up and using the LCD1280 color monitor:

• The optimum monitor position is facing away from direct sunlight.

• Match the monitor’s brightness to the ambient room brightness. 

The brightness control should be adjusted to a point where the 

overall background area just begins to disappear.

• If possible, use a white background and black text to ease eye 

strain.

• Do not place any heavy objects on the power cord.  Damage 

to the cord may cause shock or fire.

• Handle with care when transporting.

• Use the monitor in a clean and dry area.

• Clean the LCD surface with a lint-free, non-abrasive cloth and a non-

alcohol, neutral, non-abrasive cleaning solution or glass cleaner.

• For optimum performance, allow 20 minutes for warm-up.

• Avoid displaying fixed patterns on the monitor for extremely long 

periods of time to avoid after-image effects.

Connection to Graphics Cards using BNC cables

The NEC LCD1280 color monitor complements a host of

computing platforms.  However, because the LCD1280 is a

high resolution, full color analog monitor, it may require

the use of a graphics card (sometimes referred to as a

video card, video adapter or graphics board) that sup-

ports high resolution graphics (1280 x 1024), 24-bit color

(16.7M colors), delivers an analog output, and which has

a high resolution pixel frequency of 107.5 MHz ± 50 ppm

or 107.352 MHz ± 50 ppm.  Silicon Graphics’ INDIGO2

workstation does not require a graphics card. (For a current

list of compatible platforms please call NEC’s FastFacts at

1-800-366-0476 and request document #52301280).
To attach the monitor to your system, follow these instructions:

1. Turn off the power to the monitor and computer.
2. If necessary, install the graphics card and drivers.  

Determine the pixel frequency (DOT clock) output and the 

SYNC method used by the graphics card or system.  For 

more information, refer to the graphics card or system manual 

or the FastFacts document referred to above.

3. Make sure the H-SEL switch on the rear of the panel 

is positioned to the appropriate pixel frequency (if you are 

not sure, refer to the board manual or documents).  Under 

most cases, a timing of 107.5 MHz will apply (Mode 1).  For 

SGI’s INDIGO2, a timing of 107.352 MHz applies (Mode 2).
