LCDs do smart processing. In the past reaction time of the crystals was also kind of slow, but that isn't a factor nowadays. It's just the various filters that are applied on top of the image to make it "pop" more. Edit: some high-hz TVs can have 2 or even 3 frames of lag, due to having frame interpolation algorithms that take a 23.97/24/25/30/etc signal and interpolate it to the native 144hz. The frame interpolation algorithm needs to know 2 or 3 frames in advance, so it buffers up those.
