I would recommend over 100hz for 3D movies. Though, specifically for this monitor, in the LG site, it clearly states that it does not support 3D technology.
I am not sure what your budget is, but I found two monitors that are worth checking out. Acer Predator XB240H BMJDPR 24-inch Full HD 3D Vision from amazon.in (16,800 Indian Rupees) or Acer GN246HL Bbid from amazon.in (16,100 Indian Rupees)
