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.
