Reasons For

LG 55UF770 LG 55UF850 LG 55UG870 Panasonic TX-55CX700
6 Reasons For
£11 Cheaper
The LG 55UF770 costs £10.95 less than the LG 55UF850 and costs £650 less than the LG 55UG870.
More Shops Are Selling it
A greater number of stores increases the chances of this TV remaining in stock and also increases the price competition amongst retailers for the product.
Better Energy Efficiency Rating
The energy efficiency rating of the LG 55UF770 is "A+", however the rating of the LG 55UF850 is "A+", the rating of the LG 55UG870 is "A+" and the rating of the Panasonic TX-55CX700 is "B".
Expert Reviews Are a Lot Better
The average expert review score of the LG 55UF770 is 100% based on 1 review, however the average rating of the LG 55UF850 is 77% (based on 20 reviews) and the average rating of the Panasonic TX-55CX700 is 83% (based on 4 reviews).
Better Brand
LG TVs have an average rating of 86.5%, whereas Panasonic has an average rating of 46.7%.
Better for Watching Films
The LG 55UF770 is better for watching films than the Panasonic TX-55CX700.
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!

7 Reasons For
3D
The LG 55UF850 is a 3D TV (as are the LG 55UG870 and the Panasonic TX-55CX700), however the LG 55UF770 is not 3D.

‘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.

Significantly Thinner
The LG 55UF850 is a 50.8mm thick TV, whereas the LG 55UF770 is a 56.7mm thick TV (5.9mm thicker), the LG 55UG870 is a 98mm thick TV (47.2mm thicker) and the Panasonic TX-55CX700 is a 54mm thick TV (3.2mm thicker).

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.

600Hz Faster High Frequency Rate
Panasonic TX-55CX700 is 800Hz refresh rate, but the LG 55UF850 and the LG 55UG870 are both only 200Hz refresh rate TVs (600Hz 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.

Better for Watching Sport
The Panasonic TX-55CX700 is better for watching sport than the LG 55UF770, LG 55UF850 and LG 55UG870.
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.

The LG 65UF850V is a 4K LED TV from the middle of the Korean giant's new range. When LG announced its TVs for 2015 , the focus was all on 4K OLED ? and our first experience of 4K OLED was very positive. But what of the LED screens that still make up ...

LG has done solid work with the 65UF850V. It offers a strong picture performance and decent sound.We're also very pleased with the LG's app support, super-slick smart interface, and the versatile remote control. If you have £2500 to spend on a TV, t...

2015 saw a summer of love for Panasonic: four consecutive five-star review televisions between June and August, with one of those ? the TX-40CS520 ? grabbing our 2015 Award for a sub-£500 set. Ignoring the company's first-ever OLED (the TX-65CZ952B ...

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.

Compare the best TVs for gaming.

Key Features

3D

‘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.

High Frequency Rate

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.

Thickness

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.

Energy Efficiency

Energy Efficiency Class

LG 55UF770 LG 55UF850 LG 55UG870 Panasonic TX-55CX700

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.
