Reasons For

6 Reasons For
3D Edit
The LG 55UF8517 is a 3D TV, whereas the Panasonic TX-55CX680 is not 3D. Read more

3D technology has become increasingly popular as the amount of 3D film and TV content has increased dramatically in recent years. All 3D TVs will also display regular 2D content and most will allow you to switch on and off the 3D effect on 3D content. Most 3D TVs require you to wear special 3D glasses in order to view the content in 3D, however some of the newer 3D TVs require no 3D glasses at all. Of those TVs that do require glasses, there are two main types of 3D technology: passive and active. Passive 3D uses glasses similar to those that you wear in the cinema. The glasses have polarised lenses which ensure that the correct image is displayed to each eye. The main advantage of passive 3D is that the glasses are very light and comfortable to wear, but it can result in a less bright image. Active 3D uses battery powered glasses which control active shutters in each lens. These shutters constantly open and close very quickly in sync with two different images that are being displayed by the TV. This ensures that the correct image is displayed to each eye. The main advantage of active 3D is that the image is brighter, however the glasses are heavier and more expensive.

3D compatible TVs allow you to watch 3D content. For most TVs you will need to wear special glasses to see the 3D effect.

55% lower annual energy consumption Edit
The LG 55UF8517 is a 117kWh annual energy consumption TV. That's 64kWh lower than the Panasonic TX-55CX680 (181kWh). Read more

The annual energy consumption is the total amount of energy that the TV will use over the course of a whole year, given typical usage levels.

A lower annual energy consumption means that it will cost less each year for you to run your TV.

Thinner Edit
LG 55UF8517 is 50.8mm thick, but the Panasonic TX-55CX680 is a 56mm thick TV (5.2mm thicker). Read more

The depth of the TV is the thickness of the 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.

2% lighter Edit
The LG 55UF8517 is a 19.3kg heavy TV. That's 200g lighter than the Panasonic TX-55CX680 (19.5kg). Read more

The weight is the total weight of the TV excluding all packaging.

A lighter weight TV will be easier to move around and to mount on a wall. Some of the larger, very heavy TVs may require lightweight partition walls to be reinforced before the TV could be mounted.

39% cheaper to run
The LG 55UF8517 is £83.16 cheaper to run than the Panasonic TX-55CX680 over five years. Read more
Better energy efficiency rating
The energy efficiency rating of the LG 55UF8517 is "A+", however the rating of the Panasonic TX-55CX680 is "B".
