So I got a old lgtv I’m tryna connect my Xbox one s up to it with my converter.. but before I go spending and potentially losing money on something I don’t need I need confirmation. Can I just go ahead and buy the standard phono rca cables 3x3 yellow red and white and this will bring picture and sound ? Or do I need the 3x6 cable if that’s even a thing? I’m guessing the red white and yellow to green blue and red would be better right? Where would I find one of these cables can’t seem to find these colours anywhere that connect from the yellow red and white why is that? Please any help would be appreciated
