6.3.8.4. Input parameter settings for 'HDMI' type boards
Covered boards: MX-HDMI-IB, MX-DVI-HDCP-IB, MX-HDMI-TP-IB, MXD-HDMI-TP-IB,
Input equalization
The signal amplitude decreases after passing through long copper cables. The input port
can amplify the signal to a certain level, which is defined by the DVI standard. This
process is called equalization.
The Auto setting means that equalization will be adaptive (depending on the cable
length). By default, automatic equalization is enabled.
Automatic mode usually provides perfect transmission but at longer distances and higher
resolutions, manual equalization may be necessary. Manual equalization can be set to
fixed 3, 9, 25, 35 or 40dB. Longer cables need higher equalization.
Keep in mind that a previously set manual equalization level may not be suitable for a
different system. It is always advised to use the automatic mode and only adjust the
equalization manually if the auto mode does not give a good result.
Info: The MX-CPU2 Test input port does not have cable equalization!
Set color range
Some sources may send the video signal with different color range. If the black or white
level seems to be incorrect in the picture try to set this parameter to compress or expand
the color range. The default setting is no change which gives good result in most cases.
HDCP enable
The HDCP capability can be enabled or disabled on the input port. This can prevent
unnecessary HDCP encryption with certain source devices. Note that only unprotected
contents can be played on the source if this setting is disabled (unchecked). See section
4.4 on page 36 for more information.
