Screen measurement 20
Screen measurement
The easiest way to do the screen measurement is by having the BeoSystem 4 within 1.8 m/6 ft distance from the BeoVision 12-65 if at all possible.
If this is not possible, see “Distance between BeoSystem 4 and BeoVision 12-65” below.
Screen measurement - introduction
The BeoSystem 4 requires some measurements to be made to match it to the BeoVision display it is connected to. These measurements consist of
two measurement sequences:
-
MEASURE SCREEN
: a measurement of the colour reproduction of the BeoVision display.
-
MEASURE LIGHT SENSOR
: a measurement of the ambient light sensor of the BeoVision display.
Prerequisite
The measurement involves the use of a reference
measurement device
, taken into use during installation by the installer. The reference
measurement device is part of the Calibration kit BeoSystem 4; Bang & Olufsen Part No. 3376493.
If the screen measurement is not made, the following text will be shown each time the television is switched
On
:
SCREEN NOT MEASURED
PLEASE CONTACT YOUR INSTALLER
Distance between BeoSystem 4 and BeoVision 12-65
Due to the length of the cable of the
measurement device
the distance between the BeoVision 12-65 and the BeoSystem 4 must be no more than
1.8 m/6 ft.
If the distance is longer, a USB extension cable must be used so that the measurement device can be connected to the USB socket of the
BeoSystem 4.
When USB extension cables longer than 5 m/16 ft are needed, they must be USB Active Extension Cables.
