Hi Morgan,
The filter used with L and C are placed close to the
connector. From the Signal Integrity point of view
they degrade the Integrity of Signals at the receiver
end. Use the minimum values of L and C that that
passes the EMI and EMC compatibility.
The RBG Signals can be characterized by terminating
with 75 Ohm resistors at the connector and displaying
alternate Black/White Patterns. The VESA/VSIS
specification calls for Max Luminance voltage of 0.700
Volts +0.07 / 0.035 Volts. There are other less
important specifications - like Linearity, Video noise
injection ratio, Rise/Fall time etc.
I had checked with Rage-XL and no ibis or other
behavioral models were available.
