I got 2 pair of Cheap IR based DLP glasses for my Mitubishi 65737. I had been using them on and off for 5 months on standard mode sometimes with a lot of eyestrain and always dissatisfied with the 3d effect. Recently I try it in reverse mode and huge difference! Almost no eyestrain and much better looking effect. What is even stranger is that in content I can send out to the TV in either L/R or R/L, for some reason the effect is better and the eyestrain is virtually not there when I have it set to L/R and reverse, or R/L and standard. I thought standard is L/R and reverse is R/L so why am I much more satisfied when it is backwards?
