Size isn't what makes it less smooth, it's the refresh rate. People here think size and resolution are what makes a badass TV, however, their 120" TV with 1080p and 60 hz will be complete shit compared to a 65" 1080p with 240 hz. Resolution only matters for the detail, however, if it lights forming the resolution cannot keep up with what is happening on screen, such as with games that have a ton of motion, then it causes blurred effects and everything seems to be choppy or not smooth.
