The colour adjust tool in the XDi
software, is not able to adjust the colour of the backlight LED’s in a new service
unit, but it is adjusting the colours of the indicator graphics instead, to best possible match the colours of the old
and aged indicator display. The most important is the batch of the white background colour typically used in the day
designs of most virtual indicators.
In many situation this is a good way to make a replaced indicator fit into an existing indicator system, with many
years of continuous operation behind.
The colours of a new XDi unit with a display that has been colour calibrated to match an old display, will be more
sensitive to different viewing angles then the old, aged display. Unfortunately, that is the nature of this phenomena.
If the colour calibration is not sufficient in a given installation, it can be necessary to upgrade the other old
indicators with a new display to get a unified look.
