I thought I'd let other owners of the 60638 know that the Playstation-branded universal 3D glasses that are widely available work like a charm with this TV.
When I bought my TV I also got the Mitsubishi 3D starter pack and have been enjoying 3D for over a year now... but just last week I clumsily dropped a pair of my glasses on the hardwood floor and shattered one of the lenses.
I wanted to get a new pair quicklyI had just gotten Hugo on blu-ray 3D!but I didn't have a lot options locally. I saw that the Playstation glasses, which most Walmarts carry, supported "most" Mitsubishi models, so I thought I'd gamble and see if they work.
So far, I think they blow the ones that came with my starter pack out of the water. I don't have to crank up the brightness anymore to watch 3D, and though ghosting and crosstalk was minimal at most before, now I don't see it at all. Plus, if you've got a PS3 like me, you can plug 'em in via USB to charge.
Highly Recommended, and they're only around $55 on Amazon.
