Reasons For

4 Reasons For
19% larger screen size Edit
The LG 49UF671 has a screen size of 49", however the Sony KDL-40R553 is only a 40" TV (9" smaller). 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.

50% higher RMS rated power Edit
The LG 49UF671 is a 20W RMS rated power TV. That's 10W higher than the Sony KDL-40R553 (10W). 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 Edit
The LG 49UF671 is a two RF port TV, whereas the Sony KDL-40R553 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.

8.3mm thinner Edit
The LG 49UF671 is a 56.7mm thick TV. That's 8.3mm thinner than the Sony KDL-40R553 (65mm). 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.

8 Reasons For
