The truth is that it's technically impossible to get better than 60hz from your tv because our electrical grid is on a 60hz structure. So when a tv says it's anything other than that they are enhancing the appearance of the native picture. That being said, I believe Sony's technique to be the best executed enhancement. Here's an explanation pulled from the bestbuy website: Today, a growing number of HDTVs offer a refresh rate of 120Hz. These televisions can refresh images at twice the rate of 60Hz HDTVs and, when coupled with advanced processing, can help produce a picture with smoother, more natural motion. Sony Motionflow To achieve 120Hz, some manufacturers employ black frame insertion. Since 120Hz is double the refresh rate of 60Hz, they simply add a black frame in between the original frames. The resulting picture, while 120Hz, may appear dimmer as a result of every other frame being black. Others use something called scanning backlight, which divides one frame into two. If you were to look at one of these divided frames only, it might appear as if you're viewing the image through bars. Basically, it breaks the image in two at a speed your eyes can't detect, allowing the HDTV to display with a refresh rate of 120Hz. Sony Motionflow Sony, however, employs the temporal frame interpolation method in its advanced Motionflow 120Hz and 240Hz technology. Instead of just inserting black frames or stretching out single frames into multiple frames, Motionflow technology uses a unique Sony algorithm that analyzes objects, speeds and movement in individual frames for just about any video content. It then creates new images based on that data and inserts them between existing frames. This doubles (120Hz) or quadruples (240Hz) the number of full video images displayed on the screen per second, resulting in far more natural motion and a greatly improved picture.
Sorry, there was a problem. Please try again later.Motion Flow is Sony's term for refresh rate.
