Reasons For

LG 55UH668 Panasonic TX-50DX750
4 Reasons For
Larger Display Diagonal
The LG 55UH668 is a 55" TV. That's 5" larger than the Panasonic TX-50DX750 (50").

‘Display Diagonal’ is the measure of the size of the TV screen from top-left to bottom-right corner, excluding any frame or border.

One of the most important considerations when choosing the right screen size for your TV is the typical distance from which you will be viewing the screen. TVs with a bigger display diagonal allow you to make the most of HD content and are great for watching movies. A good rule of thumb is to multiply the display diagonal by 2.5 to determine the viewing distance. So a 40 inch TV is best viewed from 100 inches away, which is equivalent to 8.3 feet or 2.54m. For home cinema setups and a truly immersive experience this ratio can be reduced to 1.2. This will give a screen size that fills 40 degrees of the viewer's field of vision. So if you viewing from a distance of 6ft (72 inches) you would need a TV display diagonal of 60 inches.

£30 Cheaper to Run Over Five Years
The LG 55UH668 is £30 cheaper to run than the Panasonic TX-50DX750 over five years.

Higher Energy Efficiency Rating
The energy efficiency rating of the LG 55UH668 is "A+", but the rating of the Panasonic TX-50DX750 is "A".
Better Brand
LG TVs have an average rating of 86.2%, however Panasonic has an average rating of 51.9%.
5 Reasons For
3D
The Panasonic TX-50DX750 is 3D, but the LG 55UH668 is not.

‘3D’ describes whether the TV can display 3D movies and programmes. Requires compatible 3D glasses to properly function.

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

Read more Read less | Edit
Significantly Faster High Frequency Rate
The Panasonic TX-50DX750 is a 1,800Hz refresh rate TV, whereas the LG 55UH668 is only a 100Hz refresh rate TV (1,700Hz slower).

The refresh rate (also known as the high frequency rate) is the number of times that the image on the screen is refreshed per second. It affects how smoothly motion on the screen appears.

Action will appear smoother on TVs with a higher frequency rate: a TV with a high frequency rate of 30Hz refreshes the image on the screen once every 30 times every second. However a TV with a high frequency rate of 60Hz would refresh the image on the screen 60 times every second which means that action scenes would appear smoother.

Read more Read less | Edit
53% Thinner
The Panasonic TX-50DX750 has a thickness of 40mm. That's 20.9mm thinner than the LG 55UH668 (60.9mm).

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.

Better for Watching Films
The Panasonic TX-50DX750 is better for watching films than the LG 55UH668.
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!

Better for Playing Games
The Panasonic TX-50DX750 is better for playing games than the LG 55UH668.
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.

Running Costs Over 5 Years

TV running costs calculated based on an average of 5 hours of use per day. The running cost comprises the electricity cost when using the TV and the electricity standby cost. Compare all energy saving TVs.

Environmental Impact

We have calculated the amount of CO2 that will be generated by running each of these TVs for 5 years. We have then converted that into the number of tree seedlings that you would need to plant and grow for 10 years in order to offset that amount of CO2.
