Some TVs that offer VRR ( Variable Refresh Rate) disable local dimming to achieve it. As you can imagine showing a black screen half of the time can reduce display brightness by up to 50%! Unfortunately, BFI also takes a significant bite out of image brightness. How we perceive motion and track movement over the screen creates blur, and BFI is an effective way to create crisp motion on flat panels. They hold the entire image perfectly until the next frame is due and switch instantly. Flat panel displays (such as LCD and OLED) suffer from smeary motion thanks to their “sample and hold” nature. Why? The idea is to simulate the pulse and fade of CRT (Cathode Ray Tube) screens. This technology inserts a completely black frame between every true frame of the content. Chief among these is BFI or Black Frame Insertion. Unfortunately, some of these features also hurt brightness. Many displays now have various features that help improve motion clarity or smoothness. Turn Off Features Like Black Frame Insertion or Variable Refresh Rate If you don’t see this option, it means your display doesn’t support the feature in the first place.
