Introduction
Monitor Features
The main features of the ELSA ECOMO 21S99 are described below to give you an over-
view of the monitor’s capabilities.
On-Screen Display
Settings for the monitor can be adjusted quickly and easily using the on-screen display
menu.
Multi-mode technology
The multi-mode technology is controlled by the microprocessor. The monitor synchroniz-
es itself automatically to all frequencies in the horizontal range between 30kHz and
96kHz, and in the vertical range between 48Hz and 160Hz. Microprocessor control al-
lows the monitor to operate in any frequency mode with the precision of a fixed-frequen-
cy monitor.
Storage for graphics modes
Besides the factory settings for popular display standards, the
ECOMO 21S99 can store
user-defined settings and other timings.
Dynamic focus
The distance over which the electron beam is projected varies considerably over the
width and height of the screen, an effect which is especially significant with larger mon-
itors. The dynamic focus function automatically adjusts the focal length of the beam to
ensure that the picture stays sharp, even at the outer edge.
Moiré correction
An adjustable Moiré correction compensates for the unwanted wave-like interference
patterns from background rasters.
TCO ’95 - The latest standard
Your ELSA monitor complies with the CE radiation norm which officially defines criteria
for safety and electromagnetic compatibility. The TCO ’95 and similar approvals addition-
ally define the conditions for visual ergonomics, low radiation, energy saving functions
and ecology. Thus the
ECOMO 21S99 meets all the requirements laid down in the EU Di-
rective 90/270/EEC for monitors in the working environment.

Introduction
ELSA ECOMO 21S99

Plug&Play (DDC)
The
ECOMO 21S99 is equipped with the DDC1 and DDC2B functions (DDC = Display Data
Channel), which the monitor can use to transmit information (e.g. graphics modes sup-
ported and timing) to the host computer. This system works only if the host computer (the
graphics card) also supports the DDC function.
Power management (VESA DPMS)
The monitor has a power saving function which reduces the power consumption in stages
if the monitor is not in use.
Macintosh and the ELSA monitor
ECOMO 21S99 is a multi-frequency monitor which can also be connected to Apple Mac-
intosh computers. A suitable adapter is required to make this connection.

Monitor Settings
The monitor settings can be fine tuned according to your preferences. Don’t be afraid to
experiment with the monitor and try out all of the options for adjustment. If the picture
has gone completely astray, just press the RESET “emergency button” to restore the fac-
tory settings (➞page15).
After Switching On
Plug&Play
Today’s graphics boards, and the ECOMO 21S99 , are capable of communicating using
DDC (Display Data Channel). The
ECOMO 21S99 can send its parameters to the graphics
board. In turn, the graphics board ensures that the monitor operates at the highest pos-
sible refresh rate for the resolution selected. This means that you will normally get a pic-
ture straight away that needs only minor adjustments. Check the fine tuning of the
picture and adjust the picture for the relative light levels of your working environment.
You will now find out what settings are possible and how to solve any problems.
Language
The ECOMO 21S99 can display its on-screen menus in a choice of lan-
guages. If you want to change the language used for the on-screen
menu, simply call up the menu page illustrated here and select the
language you want.

This effect is also known as “Trapezium bal-
ance”. Use the selection keys to access the
‘GEOM’ menu page. Move the cursor onto the

option using the 쒅/쒆 buttons. You can use
the 쏟/쏡buttons to rotate the picture and cor-
rect the rotational effect.
The Picture Has a Wave-Like Pattern Superimposed On It
Moiré
Correction
Modern monitors are affected by the undesirable side-effect of moiré. This is particularly
noticeable with a light background screen brightness and can often be eliminated by
selecting another background color. This effect produces an interference pattern which
results from a displacement between the electron beams and the shadow mask. Beam
point and shadow mask converge precisely in some parts of the screen, producing a
bright picture. Minor deviations make for a somewhat darker region in other parts of the
screen.
Use the selection keys to access the ‘PIC-
TURE’ menu page. Move the cursor onto the
desired option using the 쒅/쒆 buttons.
Change the setting for ‘MOIRE’ using the 쏟/쏡
buttons to correct the effect of moiré.

The Picture Has Blue or Red Shadows
Convergence
The three electron beams are not in registration and are not
hitting the phosphor dots on the viewing screen accurately,
resulting in a fuzzy picture on the screen and the appearance
of red or blue shadows around objects. This is called conver-
gence error. The three control bars on the OSD page will help
to adjust the convergence. The convergence value is correct
when the color bars are “sharp”.
The
ECOMO 21S99
makes it possible to correct the conver-
gence very accurately:
쮿Vertical convergence
쮿Horizontal convergence
쮿Upper screen convergence
쮿Lower screen convergence
Use the selection keys to access the ‘PIC-
TURE’ menu page. Move the cursor onto the
desired option using the 쒅/쒆 buttons. Use
the 쏟/쏡buttons to adjust the convergence
correction.
The Screen Colors Look Blotchy
Color Purity
Colors will loose uniformity if the three elec-
tron beams are being deflected. This effect
may be the result of interference from a mag-
netic field or if the monitor has been moved
while switched on. The
ECOMO 21S99
allows the grade of color purity to be
adjusted in all four corners of the screen.
Use the selection buttons to access the ‘PICTURE’ menu page.
햲First move the cursor onto the first
‘COLOR PURITY’ symbol using the
쒅/쒆 buttons. The four icons for the
corner regions affected appear in the
right-hand detail. Select the icon you
want using the 쏟/쏡buttons. The selec-
tion is highlighted by a small green
square.
The bars should coincide
exactly.

Printer and Screen Colors Should Match
Color
Temperature
Color temperature setting enables you to set up your monitor’s background white to
match the white of the printer paper. You can match the colors on screen to match printed
output or some other color swatch. The lower the value, the brighter the paper quality.
Use the selection buttons to select the next
menu page, ‘COLOR’. You can use the 쏟/쏡
buttons to switch between the three color
temperatures, 5000K, 6500K and 9300K,
where 6500K represents the value for
default white. The screen picture changes at
the same time.
If you are an experienced user and need to match the screen picture very closely to a color
swatch, it is possible to match the black proportion (BIAS) and the white proportion
(GAIN) of each of the three color temperatures for the red, green and blue (RGB) color sig-
nals.
Options
You will find additional settings and functions for the monitor in the
‘OPTION’ menu.
Degaussing
The monitor screen is automatically degaussed whenever it is turned
on. You can, of course, manually degauss the monitor.
