Reasons For

2 Reasons For
19% larger display diagonal Edit
The LG 49UF671 has a display diagonal of 49", however the Sony KDL-40R553 is only a 40" TV (9" smaller). Read more

‘Display Diagonal’ is the measure of the size of the TV screen from top-left to bottom-right corner, 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. TVs with a bigger display diagonal allow you to make the most of HD content and are great for watching movies. 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.

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.
