Closely full televisions that claim 120 Hz do not really do fact 120 Hz with Computers. Almost of them just accept 60 Hz insert sources, and just function frame interpolation. For few games, it might appear good, but it feels leggy. The just difference I can see is that the IIId example utilizes a clear glossy panel whereas the non-IIId one utilizes a matte black panel i.e. it will give without reflections, if you have plentys of light in your room.
