Manual Picture Adjustment - D-Sub Input
This section applies to the D-Sub input, only, as it is the input
connection for analogue RGB graphics, including VGA-type
signals. Adjustments to the displayed image are made using
the On-Screen Display's Geometry submenu, described previ-
ously in this chapter.
To manually adjust the image:
1
Display the adjustment test pattern. This is the best way to
observe changes as you adjust the image. Windows users
should run the Auto.exe test pattern program provided with
the monitor on floppy diskette. For non-Windows operating
systems, you also can use the test pattern described in the
previous section or another full-screen image, such the
desktop of the operating system.
2
Open the OSD menu by pressing the Menu button on the
monitor.
3
Select the Geometry submenu and then press Menu.
4
Select Clock and then use + or - to tune the sampling clock
to get the optimum picture. Look at the centre section of
the test pattern that has alternating black and white vertical
lines that are each 1 pixel wide. There should be no vertical
noise bands visible within the image. The centre section
will clearly show the alternating black and white lines or a
uniform level of noise will appear across the image.
5
Select H. Position and adjust the horizontal position so
that the image is centered. Its width should be the exactly
same as the width of the active area of the screen.
6
If some noise or distortion is still visible in the centre sec-
tion of the test pattern, select Phase and use + or - to
adjust the phase of the sampling clock. The alternating
black and white lines in the centre area of the test pattern
should be clearly visible and distinct.
7
Press Menu to go back to the main OSD menu.
