Analog Display Graphics Subsystems Proposal (Version 1, Draft 4, December 1, 2000).

Max steady-state amplitude

Min steady-state amplitude

Defined for a double 75 Ω termination.

Set by external reference resistor value.

INL and DNL measured and calculated according to VESA Video Signal Standards.

Max full-scale voltage difference among R, G, B outputs (percentage of steady-state full-scale

voltage).
