4-3. OSD Adjustments
You can play the movie
file to see how to adjust
the picture image by
clicking each icon or title
hereunder.
The OSD adjustments available to you are listed below.
H. SIZE
Adjusts the horizontal size of the entire screen image.
H. POSITION
Adjusts the horizontal position of the entire screen image.
V. SIZE
Adjusts the vertical size of the entire screen image.
V. POSITION
Adjusts the vertical position of the entire screen image.
PINCUSHION
If the vertical sides of the picture curve in or bulge out, you can correct
the pincushion distortion by using this adjustment.
TRAPEZOID
If the picture is wider at the top or at the bottom, you can correct the
trapezoid distortion by using this adjustment.
PARALLEL
If the sides of the screen image are tilted, you can correct the parallel
distortion by using this adjustment.
F230
Perfectly Flat Color Monitor
12/20
BACK
NEXT
PIN BALANCE
If the sides of the picture are bowed to the right or to the left, you can
correct the pincushion balance by using this adjustment.
V. MOIRE
Clears vertical moire if a series of concentric circles or arcs appear on
your screen.
H. MOIRE
Clears horizontal moire if a series of concentric circles or arcs appear
on your screen.
Moire is an interference pattern that makes the screen seem to have
faint lines. A picture that is rasterised or consists of (small) repeating
figures is sensitive to moire interference. Strong colors are also liable to
intensify moire.
The moire pattern on the screen does not affect the printout of the
image.
TOP CORNER
If the top corner sides of the picture curve in or bulge out, you can
correct the top corner distortion by using this adjustment.
BOTTOM CORNER
If the bottom corner sides of the picture curve in or bulge out, you can
correct the bottom corner distortion by using this adjustment.
F230

H. LINEARITY
If either left or right side of the picture is out of proportion to the other,
you can correct horizontal linearity by using this adjustment.
V. LINEARITY
If top and bottom side of the picture is out of proportion to the center
area, you can correct vertical linearity by using this adjustment.
BNC / D-SUB
Press the SELECT button to select signal source. (BNC or D-SUB)
PURITY
If primary color like white, blue or red is displayed on the whole screen
and some areas or dots are showing different colors, you can correct
them by using this adjustment.
Color purity error is caused by misalignment of one of the electron
beams (R,G, B). Each beam is set to strike only phosphor dots of a single
color like the red beam for the red phosphor dots only. If such beam is
misaligned to strike incorrect phosphor dots, then the colors of the
screen will be incorrect.
H. CONVERGENCE
If the shadows appear around the text or graphic image, you can remove
them horizontally by using this adjustment.
V. CONVERGENCE
If the shadows appear around the text or graphic image, you can remove
them vertically by using this adjustment.
PR
HC
VC
F230
Perfectly Flat Color Monitor
Convergence is related to the three electron beams (Red, Green and Blue)
which come together at a single spot on the screen. If the individual
electron beams do not converge perfectly, mis-convergence error appears
as shadows around text and graphic images with different colors than
you designated.
LANGUAGE
You can select the language in which adjustment menus are displayed.
The following languages are available; English, French, German, Italian,
Spanish, Swedish, Finnish, Danish and Portuguese.
ROTATION
If the entire screen image is tilted, you can correct the distortion by using
this adjustment.
OSD H. POSITION
Adjusts the OSD menu’s horizontal position on the screen.
OSD V. POSITION
Adjusts the OSD menu’s vertical position on the screen.
COLOR CONTROL Color temperature affects the tint of the
image. With lower color temperatures the
image turns reddish and with higher
temperatures bluish.
There are three color settings available:
9300K, 6500K or USER. With the USER
setting you can set individual values for red,
green and blue.

RECALL
If you operate your display unit in a factory preset mode, this function
deletes adjustments you made for size, position and shape, and restores
the properties which have been set in the factory. If you operate your
display unit in a user mode, this function has no effect except that the
contrast will be reset to the maximum value and the brightness to the
cut-off level.
INFORMATION
Information shows horizontal and vertical sync polarity of current timing
set.
DEGAUSS
External magnetic fields may cause distortion or discoloration in the
picture. Demagnetizing takes place automatically when the display unit
is switched on, and the unit normally maintains faultless color purity
during operation.
If you have tilted, swiveled or moved the display unit, you can perform
demagnetization. During this process the picture is distorted for a few
seconds. After demagnetizing, the color impurities have disappeared if
caused by stray magnetic fields.
Do not use the degauss feature more than once every half hour.
CONTRAST
Adjusts the contrast of the screen.
BRIGHTNESS
Adjusts the brightness of the screen.

The display unit might be in standby mode. Push one of the
keyboard keys. Check that the keyboard is properly connected to
the computer.
Check that the power cable is correctly connected to the display unit
and to the power outlet.
The graphics adapter is set for too high refresh rate or line
frequency. Select another display mode with lower frequencies in
computer.
This message indicates that the signal is missing or faulty. Check
that the signal cable connector is properly connected and that the
connection pins are not bent or damaged. If the connector is loose,
tighten the connector's screws.
The video signal from the computer does not comply with VESA
DPMS standard. Either the computer or the graphics adapter is not
using the VESA DPMS power management function.
If your monitor is not functioning properly, you may be able to solve the problem
by reading followings.

Possible solution
The screen may seem to flicker when the refresh rate is less than
75Hz. See the list of recommended modes in the section Preset
timing table.
If your color is not uniform, demagnetize the display unit as
described in the section Degauss under OSD adjustments, and make
sure that the display unit is at least 30cm from any other electrical
equipment.
Check that the signal cable connector is properly connected and that
the connection pins are not bent or damaged. Try another color
temperature.
If the picture has strong color defects, switch off the display unit
and the computer.
Make sure that other electrical devices are at least quality 30cm
away.
Adjust the picture characteristics as described in the section
