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 Edit
The Sony KD-55XD8599 is a three USB 2.0 port TV, whereas the LG 55UH850 only has two USB 2.0 ports. 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 port Edit
The Sony KD-55XD8599 has four HDMI ports, however the LG 55UH850 only has three HDMI ports. 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.

£50 cheaper
The Sony KD-55XD8599 costs £50 less than the LG 55UH850.
Available from 23 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+".
