Reasons For

4 Reasons For
Larger display diagonal Edit
The Panasonic TX-55CX680 is a 55" TV. That's 5" larger than the Sony KDL-50W756 (50"). 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.

10W higher RMS rated power Edit
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). 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.

A little thinner Edit
The Panasonic TX-55CX680 has a depth of 56mm, however the Sony KDL-50W756 is a 59mm thick TV (3mm 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.

Available from 1 shops
A greater number of retailers increases the price competition amongst retailers for this TV and also increases the chances of the product remaining in stock.
5 Reasons For
Hugely faster motion interpolation frequency Edit
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). Read more

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.

Marginally wider horizontal viewing angle Edit
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). Read more

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.

Cheaper by £119
The Sony KDL-50W756 costs £119.01 less than the Panasonic TX-55CX680.
44% cheaper to run
Over five years the Sony KDL-50W756 is £92.94 cheaper to run than the Panasonic TX-55CX680. Read more
Energy efficiency rating is better
The Sony KDL-50W756 has an energy efficiency rating of "A+", however the Panasonic TX-55CX680 has a rating of "B".

Reasons Against
