LCDs do smart processing. In the past reaction time of the crystals was also kind of slow, but that isn&#x27;t a factor nowadays. It&#x27;s just the various filters that are applied on top of the image to make it &quot;pop&quot; more.<p>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&#x2F;24&#x2F;25&#x2F;30&#x2F;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.
