Reasons For

Panasonic TX-55CX680 Sony KDL-50W756
3 Reasons For
Larger Display Diagonal
The Panasonic TX-55CX680 is a 55" TV. That's 5" larger than the Sony KDL-50W756 (50").

‘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.

10W Higher RMS Rated Power
The Panasonic TX-55CX680 has an RMS rated power of 20W, however the Sony KDL-50W756 is only a 10W RMS rated power TV (10W lower).

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.

Read more Read less | Edit
A Little Thinner
The Panasonic TX-55CX680 has a thickness of 56mm, however the Sony KDL-50W756 is a 59mm thick TV (3mm thicker).

The thickness of a 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.

5 Reasons For
Hugely Faster Motion Interpolation Frequency
The Sony KDL-50W756 has a motion interpolation frequency of 800Hz, but the Panasonic TX-55CX680 is only a 200Hz motion interpolation frequency TV (600Hz slower).

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.

A faster motion interpolation frequency will result in smoother action scenes, less motion blur and a more life like image.

Read more Read less | Edit
Marginally Wider Horizontal Viewing Angle
The Sony KDL-50W756 has a horizontal viewing angle of 178°, but the Panasonic TX-55CX680 is only a 176° horizontal viewing angle TV (2° narrower).

The horizontal viewing angle dictates the maximum angle at which the TV screen can be properly viewed.

A larger viewing angle means that the TV can be watched from many different parts of a room successfully. Conversely, a very small viewing angle means you would effectively have to sit directly in front of the TV to be able to view the screen successfully.

Over five years the Sony KDL-50W756 is £71 cheaper to run than the Panasonic TX-55CX680.
