computer’s graphics adaptor is replaced.
If you are still not satisfied with the result, you can enhance the image by using
the monitor’s manual adjustment functions.
Manual Picture Adjustment
Adjustments to the displayed image and audio volume are made using the
On-Screen Display (OSD), and the buttons on the front of the monitor.
To manually adjust the image:
1. Display your operating system desktop
2. Open the OSD menu by pressing one of the Function keys on the monitor.
3. Press
Fn+
or
Fn-
to select the
Clock
function.
4. Press
+
or
-
to increase or decrease the sampling clock to get the optimum
picture. Look closely at the picture displayed, especially surrounding text
and icons, for any movement or change. Adjust the
Clock
setting and see
how this affects this “noise” or movement. Make sure that in correcting
noise in one part of the screen the setting does not create it in another.
You should, with careful adjustment, be able to obtain a picture with no
visible noise in any section of the screen.
5. If some noise or distortion is still visible select
Phase
using the
Fn+
or
Fn-
buttons.
6. With
the
Clock
set to the optimal value adjust the
Phase
to further optimise
the displayed image. You should now be able, with a combination of the
Phase and Clock settings, to obtain a perfectly stable image.
7. Finalise the manual adjustment using the
H. Position
and
V. Position
functions
If you are still not satisfied with the result, try repeating the above procedure
using a graphics signal that has a different refresh rate.
