Yeah There Is A Difference.
The Gold Plating Helps To Keep The Signal From Becoming Distorted Or Losing Signal Strength At The Connection.
This Is Because Gold Is The Best (Or Among The Very Best) Electronic And Signaling Conducters.
The Removing Of Oxygen In The Cabling And The Connections Also Does The Same Thing - By Giving Your Signal A Cleaner Connection With Maximum Conductivity By Removing Any Obstacles That Are Slowing / Distorting The Current, One Of Those Obstacles Is Oxygen.
In The End Unless Your An Audio/Videophile Like I Am - You Probably Aren't Going To Notice Any Difference On Your TV/Moniter.
Hope This Helps
