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
