NOTES:

1. Measured at each R, G, B termination according to the VESA Test Procedure – Evaluation of Analog

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

2. Max steady-state amplitude

3. Min steady-state amplitude

4. Defined for a double 75-Ohm termination.

5. Set by external reference resistor value.

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

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