DIGI-P122 / DIGI-P123 Installation Guide
EDID Management
HDMI
An essential part of operation is the EDID table, which is transmitted to the source via HDMI cable
from any HDMI input on the switcher. The DIGI-P122/123 units feature a dynamic EDID mode
for the HDMI inputs only. The preferred native timing of the EDID will match the output
resolution that the DIGI-P122/123 is set to. For example – if the output resolution of the unit is
set to 1024x768, then the switcher will request the source to output 1024x768. The benefit of
this method is that the video output by the source will not need to undergo a great deal of
processing (scaling), which will result in a cleaner image with less scaling artifacts.
VGA
Similar to the HDMI inputs, the VGA inputs must transmit a table of acceptable resolutions to the
attached source. The VGA inputs of the DIGI-P122/123 are static, and will always request a
resolution of 1360x768 from the source.
HDCP Management
HDMI Inputs
The HDMI inputs are HDCP compliant, which will allow you to use encrypted content like a Blu-
Ray player. The DIGI-P122/123 will only consume one HDCP “key”, regardless of what is
connected on the outputs.
HDMI and HDBaseT Outputs
The HDMI outputs will follow the status of the input. If the source is encrypted, the output will
be encrypted; if the source is un-encrypted, the output of the DIGI-P122/123 will be unencrypted.
VGA Output
The VGA video output will be turned off when a HDCP encrypted input is selected (HDMI only).
A black screen will replace the video input. This operation is normal, as it is necessary to comply
with HDCP regulations. Stereo audio from the PC
