It's time to replace my old TV and I'm beginning to do some research in preparation for black friday. I'm looking for a 4k TV that could be good for both movies and gaming. For movies, it has to be able to play 24fps movies at the correct frame rate. I'm not 100% certain but does this mean I need a 120Hz display? Will any 120Hz display do? I thought some displays claim 120Hz but it only works with motion interpolation settings (and personally I think those always look awful). For gaming, i just care that the input lag isn't insanely high. I have no idea where to look for research. There is so much misinformation out there.
