ADV7125 green negative amplitude does not go below 0V. I have put 75 ohm from G- to GND adn 200 Ohm between G+ to Gnd. Additionally montor has 75 ohm resistance across G+ and G-. Please can you let me know how to do this resitor calculation. Similarly I want to use R and B too differntial. 

  What resistor values I should use frpm R+ to GND, R-to GND, G+ to GND & G- to GND?

  I have seen table 7 from ADV7125 and know its current requirement but not able to do the resistor calculation.  Please can you let me know these resistor calculations.
