Reasons For

Panasonic TX-40DX700 Samsung UE40KU6400 Samsung UE40KU6470
3 Reasons For
Faster Motion Interpolation Frequency
The Panasonic TX-40DX700 is a 1,400Hz motion interpolation frequency TV. That's 1,300Hz faster than the Samsung UE40KU6400 (100Hz).

The motion interpolation frequency is the frame rate which the TV is able to artificially create by inserting additional frames into the picture between the frames included in the original video source.

A faster motion interpolation frequency will result in smoother action scenes, less motion blur and a more life like image.

What are They Best Used For

Watching Films

When ranking TVs for their suitability to display films, we’ve concentrated on several key attributes. These include contrast ratio and local dimming, which allow the dark colours on the screen to look deeper and richer - helpful for nighttime scenes. Also the screen resolution plays a part - 4K and higher resolutions mean that the image will be clearer and more detailed. Finally the size of the screen is also important - explosions and big dramatic reveals are so much more effective when you don’t have to squint to see the screen!

Compare the best TVs for film.

Watching Sport

When ranking TVs for sport, we’ve concentrated primarily on the most important attributes. First off, we concentrate on the ‘motion interpolation frequency’. This is important for fast-moving spots, since it reduces the amount of blurring on screen. We also take the size of the screen into account - sports matches are far more immersive when viewed on a giant screen! Finally, we look at display brightness and display resolution, so that the games always appear as fully-detailed and bright.

Compare the best TVs for sport.

Playing Games

When ranking TVs for games, we’ve concentrated on a number of key attributes: primarily ‘motion interpolation frequency’ and ‘high refresh rate’. Both connect to the quality of the image coming from the games console to the TV - both reduce instances of blurring caused by fast moving objects on the screen, and allow the image to appear more detailed and cleaner.
