May sound like a dumb question (& probably is) but as I'm partially sighted in one eye, I have completely ignored 3D as my world has always been 2D. I now have a TV with 3D capability (TX-P42UT50B) & the correct glasses (TY-ER3D4MA) & wondered if there's any way I can test the 3D function? The missus has tried them with 2D-3D & reckons all she sees is a slighter darker, out of focus image. Last night, BBCHD broadcast Last Night of the Proms in 3D. The picture was initially displayed as side-by-side & the 3D signal was detected, instructing to press the 3D button. This converted to the picture to what I see in 2D-3D & I asked her to try again but she again reported no difference, just a darker, out of focus image. The glasses are paired. She wears glasses for reading & different ones (distance) for driving but doesn't need them for TV.
