The LG 4K UHD HDR Smart LED TV - 70" Class (69.5" Diag), Model # 70UJ7570 has a native panel refresh rate of 60 Hz and TruMotion 120 There are two important things about you need to understand about video. First, you can't add detail beyond what is already in the source footage. Second, the source footage is never greater than 60Hz. When you watch a movie on Blu-ray, it's a 1080p picture at 60Hz and on a 4K Blu-ray player, it's 2160p at 60 Hz. The disc displays 60 interlaced or 30 progressive frames at 1,920-by-1,080 resolution per second of video. For movies that were recorded on film, the original footage is actually 24 frames per second, upconverted to 30 frames through a process known as 2:3 pulldown. It distributes the source frames so they can be spread across 30 instead of 24 frames per second. Those frames are then interlaced (combined and shuffled) to 60 "frames" per second to match the 60Hz refresh rate of the vast majority of TVs you can buy today. This is a time-honored tradition because American TVs have displayed 30 (actually, 29.97) frames per second and functioned at 60Hz since time immemorial. Once a TV's refresh rate goes above the rate of the content you're watching, it starts performing tricks to produce a higher frame rate. It interpolates new frames between the frames transmitted to the display at 60 frames per second (or processed into 60 frames per second from 24 frames per second for film footage, through the separate pulldown process), and the HDTV fills in the spaces by generating the best "middle" frames to stick in the cracks. This process is known as Motion Interpolation and different manufacturers call it by different names. LG calls it TruMotion. Trumotion allows you to enjoy the high-speed action of sports, video games and more with virtually no motion blur and in crystal clarity with LG’s TruMotion™ 120 Hz technology...^IFV
