Reasons For

6 Reasons For
Two RF ports Edit
The number of RF ports on the LG 55UF8517 is two, but the Sony KD-65X8509 only has one RF port. 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.

90kWh lower annual energy consumption Edit
The LG 55UF8517 has an annual energy consumption of 117kWh, however the Sony KD-65X8509 is a 207kWh annual energy consumption TV (90kWh 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.

54% thinner Edit
LG 55UF8517 is 50.8mm thick. That's 27.2mm thinner than the Sony KD-65X8509 (78mm). 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.

4.8kg lighter Edit
The LG 55UF8517 is a 19.3kg heavy TV, whereas the Sony KD-65X8509 is a 24.1kg heavy TV (4.8kg heavier). 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.

47% cheaper to run
Over five years the LG 55UF8517 is £113.61 cheaper to run than the Sony KD-65X8509. Read more
Energy efficiency rating is better
The LG 55UF8517 has an energy efficiency rating of "A+", however the Sony KD-65X8509 has a rating of "A".
4 Reasons For
10" larger screen size Edit
The Sony KD-65X8509 is a 65" TV. That's 10" larger than the LG 55UF8517 (65"). Read more

The display diagonal of a TV is the most common measure of screen size and is the distance from the top left to the bottom right of the visible part of a TV screen 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. 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.

TVs with a bigger display diagonal allow you to make the most of HD content and are great for watching movies.

Three USB 2.0 ports Edit
The Sony KD-65X8509 is a three USB 2.0 port TV, whereas the LG 55UF8517 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-65X8509 has four HDMI ports, however the LG 55UF8517 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.

Mobile high-definition link Edit
The Sony KD-65X8509 has a mobile high-definition link, but the LG 55UF8517 does not have a mobile high-definition link.
