Example:
If the color signal for red appears too early, select the entry delay R and delay
the signal until all colors converge again and a correct picture is displayed. If
another color signal appears on the monitor too late, repeat this process as
described above.
After establishing the delay compensation settings, confirm and save your
selection by pressing
F2 or discard your changes by pressing ESC . In both
cases, the IVT submenu is closed.
If you want to make other changes within the IVT submenu, use the UP
ARROW and/or DOWN ARROW keys to move to another entry.
5.5.4 Notes on IVT Settings
The steps described above are guidelines.
Since the quality of a video display depends on the monitor, the graphics card,
and the transmission cable, it is possible that you may achieve the subjective
"best picture" with a boost setting of 140 in spite of a cable length of 120
meters, for example.
Test the settings to find what is best for your application.
Since the UP ARROW and/or DOWN ARROW keys work in 1-meter
increments, you may have to press these keys repeatedly to achieve a perfect
picture.
If your monitor remains black, please check whether the resolution setting of
the graphics card is supported by the monitor. If this is the case, activate the
IVT submenu (
Chapter 5.5.2 ).
It is also possible that the range supported by your monitor has been
exceeded. Select the lowest setting and then move up using the
PgUp key.
The picture will reappear and you can establish the optimal settings.
