LG WRman Sherlock here!
Haha, you're right. It's easier to just buy the pair of Dual Play glasses, but it's more fun if you try to do it yourself, no? I mean imagine your friends going over for gaming nights and you're showing off your LG TV and the Dual Play function and then proudly say 'I make these glasses myself.' How cool is that?
LG WRman Sherlock out!
