Reasons For

7 Reasons For
3D Edit
The LG 55UH850 is 3D, however the Sony KD-55XD8599 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.

50% higher RMS rated power Edit
The LG 55UH850 is a 40W RMS rated power TV. That's 20W higher than the Sony KD-55XD8599 (20W). Read more

RMS rated power stands for Root Mean Square rated power and it is typically used to measure the power output of the audio element of the TV.

A higher RMS rated power means that the audio system on the TV is more powerful and will be able to play the audio at higher volumes. A higher RMS power may also result in better quality audio at normal volume levels.

Two RF ports quantitys Edit
The LG 55UH850 is a two RF ports quantity TV, whereas the Sony KD-55XD8599 only has one RF ports quantity. Read more

RF stands for Radio Frequency and an RF port is an older type of input connector for TVs which is most commonly use for connecting cable TV and satellite TV feeds directly to the TV.

Multiple RF ports will allow you to connect multiple RF feeds to the TV at the same time. For example, if the TV has a built in satellite TV decoder then you could connect 2 different satellite dishes to the TV.

Lower annual energy consumption Edit
The LG 55UH850 has an annual energy consumption of 124kWh, but the Sony KD-55XD8599 is a 143kWh annual energy consumption TV (19kWh higher). 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.

£28.85 cheaper to run
Over five years the LG 55UH850 only costs £139.24 to run whereas the Sony KD-55XD8599 costs £168.09 to run (21% more). Read more
Energy efficiency rating is higher
The LG 55UH850 has an energy efficiency rating of "A+", but the Sony KD-55XD8599 has a rating of "A+".
Slightly better expert reviews
Based on 3 reviews, the average expert review score of the LG 55UH850 is 81%, but the average rating of the Sony KD-55XD8599 is 80% (based on 1 review).
8 Reasons For
Faster motion interpolation frequency Edit
The Sony KD-55XD8599 is a 1,000Hz motion interpolation frequency TV. That's 800Hz faster than the LG 55UH850 (1,000Hz). Read more

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. Motion interpolation technology can sometimes create some unwanted side effects such glitches when the technology suddenly activates during an action scene. Most modern TVs will have an option to switch off the motion interpolation if it is not desired.

A faster motion interpolation frequency will result in smoother action scenes, less motion blur and a more life like image.

Three USB 2.0 ports quantitys Edit
The Sony KD-55XD8599 is a three USB 2.0 ports quantity TV, whereas the LG 55UH850 only has two USB 2.0 ports quantitys. Read more

USB ports are useful for displaying on your TV photos / videos or playing music that is stored on USB key drives. The USB port can also be used for charging devices from your TV (as long as it's switched on), and for installing software updates on the TV.

More USB ports will allow you to connect more USB devices to the TV simultaneously without needing to continuous plug in and unplug cables.

One more HDMI ports quantity Edit
The Sony KD-55XD8599 has four HDMI ports quantitys, however the LG 55UH850 only has three HDMI ports quantitys. Read more

The HDMI ports quantity is the number of ports that the TV has that will accept a HDMI cable. HDMI is the most common type of cable used to connect modern TVs, DVD players, games consoles etc.

A greater number of HDMI ports will allow you to permanently connect more devices to the TV and will reduce the need to reach around the back of the TV to unplug and plug in cables when switching between devices.

Thinner Edit
Sony KD-55XD8599 is 44mm thick, but the LG 55UH850 is a 51.5mm thick TV (7.5mm 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.

28% lighter Edit
The Sony KD-55XD8599 is a 15.1kg heavy TV. That's 4.1kg lighter than the LG 55UH850 (15.1kg). 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.

£20 cheaper
The Sony KD-55XD8599 costs £20.01 less than the LG 55UH850.
Available from 17 shops
A greater number of retailers 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 Sony KD-55XD8599 is "A+", however the rating of the LG 55UH850 is "A+".
