Reasons For

LG 40UF770 Panasonic TX-40DX600 Samsung UE40JU6410 Samsung UE40KU6400
5 Reasons For
Local Dimming
The LG 40UF770 features local dimming, and so does the Samsung UE40KU6400, however the Samsung UE40JU6410 does not.

'Local Dimming' on a TV is a function that dims certain sections of the backlight to control the level of light/color intensity in a given part of the screen.

Local dimming can be used to make blacks on the screen appear darker and richer by removing the backlight behind them.

Read more Read less | Edit
Common Interface (CI) Slot
The LG 40UF770 has a common interface (CI) slot, and so does the Samsung UE40KU6400, whereas the Panasonic TX-40DX600 and the Samsung UE40JU6410 do not have a common interface (CI) slot.

A common interface slot provides compatibility with pay-per-view cards.

A common interface slot allows you to install pay per view cards. For example Sky TV sell pay per cards for watching football and boxing and WWE Network sell cards for watching wrestling.

Read more Read less | Edit
DVI Port
The LG 40UF770 has a DVI port, whereas the Panasonic TX-40DX600, the Samsung UE40JU6410 and the Samsung UE40KU6400 do not have a DVI port.
Edit
PC in (D-Sub) Port
The LG 40UF770 has a PC in (D-Sub) port, whereas the Panasonic TX-40DX600, the Samsung UE40JU6410 and the Samsung UE40KU6400 do not have a PC in (D-Sub) port.

The socket (port) to receive input from a PC via a D-sub, which is a connector with a characteristic D-shaped metal shield. Also known as a VGA Port.

A D-sub port is needed to connect your TV to older devices and computers that use a VGA connection - generally those made before 2000.

Energy Efficiency Rating is Superior
The LG 40UF770 has an energy efficiency rating of "A", whereas the Panasonic TX-40DX600 has a rating of "B" and the Samsung UE40KU6400 has a rating of "A".
3 Reasons For
Significantly Faster Motion Interpolation Frequency
The Panasonic TX-40DX600 has a motion interpolation frequency of 800Hz, whereas the Samsung UE40KU6400 is only a 100Hz motion interpolation frequency TV (700Hz slower).

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.

7.7mm Thinner
The Panasonic TX-40DX600 is a 49mm thick TV. That's 7.7mm thinner than the LG 40UF770 (56.7mm), 0.5mm thinner than the Samsung UE40JU6410 (49.5mm) and 5.6mm thinner than the Samsung UE40KU6400 (54.6mm).

The thickness of a TV measured from the back of the TV to the front of the TV. Curved TVs will have quite a big depth as this dimension is measured from the back of the centre of the screen to the front of the edges of the screen.

A thinner TV has the advantage of appearing more elegant and will also mean that the TV will not stick out as much when mounted on a wall.

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.
