In the product specifications, you’ll see that both the Pioneer and the Sony are 24 fps capable or 1080/24. This does not mean the TV displays at 24 fps. It simply means the TV can accept a signal with a 24 fps frame rate. This becomes a benefit when using a Blu-ray or HD DVD player that can output the video at 24 fps. Those devices must be connected to the TV with an HDMI cable. Note that some players require that the user choose the output between 24 fps or 60 progressive fps. And you may still want to choose 1080p/60 output if the component has a superior processing chip to that of the TV like the Samsung Blu-ray player with advanced HQV processor.
Faster refresh rates benefit LCD TVs. LCD TVs have had the reputation of feathering and blurring, which has deterred sports fans and action movie enthusiasts. This happens because liquid crystals have a slow response time. The 120 Hz refresh rate makes it possible to cut the response time in half. To create a clearer picture, manufacturers may add a “motion compensation” process.
To achieve 120 fps refresh rate at 120 Hz, frames may be duplicated in a variety of ways. Sharp D-62 series achieves this frame-rate conversion by inserting a black frame between the original frames. Other manufacturers may use a reverse image or white frame to produce a crisper image.
