Reasons For

7 Reasons For
A lot higher RMS rated power Edit
The LG 50LF580 has an RMS rated power of 20W, whereas the Sony KDL-50W756 is only a 10W RMS rated power TV (10W lower). 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.

One more RF port Edit
The LG 50LF580 is a two RF port TV, whereas the Sony KDL-50W756 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.

Lower annual energy consumption Edit
The LG 50LF580 is a 92kWh annual energy consumption TV. That's 8kWh lower than the Sony KDL-50W756 (100kWh). 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.

3.2mm thinner Edit
The LG 50LF580 is a 55.8mm thick TV, whereas the Sony KDL-50W756 is a 59mm thick TV (3.2mm 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.
