It doesn’t help that there hasn’t been a new 3D set on the market for a couple years now. Maybe the Avatar sequels will revive the market. That there were two different home systems didn’t help much. Active 3D sets requiring more expensive glasses that need batteries. 4K sets actually do 3D better with no loss of resolution.
I was amazed to find out there was an outboard 3D converter gizmo for 2D sets. It uses the old red/blue system, but from what I’ve read, it works pretty well once calibrated.
