The new model is 60hz, check VUTV website.
I do not find any edge light belling or clouding as of now, can u point to any documents that says this is direct lit panel?
Motion blur is visible since this is 60hz, I think it was better in the earlier panel, but overall I'm happy that there is no clouding or back light bleeding.
It is given on VU TV website that 55K160GAU is a Direct Lit panel, check out the detailed technical specifications: Vu Play (55) 140 cm Full HD LED TV - Vu Televisions
