Reasons For

2 Reasons For
A lot thinner Edit
The Panasonic TX-40CX680 is a 47mm thick TV, whereas the Sony KD-49X8308 is a 60mm thick TV (13mm 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.

£30.44 cheaper to run
The Panasonic TX-40CX680 is £30.44 cheaper to run than the Sony KD-49X8308 over five years. Read more
4 Reasons For
19% larger display diagonal Edit
The Sony KD-49X8308 is a 49" TV. That's 9" larger than the Panasonic TX-40CX680 (49"). 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.

80% faster motion interpolation frequency Edit
The Sony KD-49X8308 is a 1,000Hz motion interpolation frequency TV. That's 800Hz faster than the Panasonic TX-40CX680 (1,000Hz). 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.

2% wider horizontal viewing angle Edit
The Sony KD-49X8308 is a 178° horizontal viewing angle TV. That's 2° wider than the Panasonic TX-40CX680 (178°). 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.

Higher energy efficiency rating
The energy efficiency rating of the Sony KD-49X8308 is "A", but the rating of the Panasonic TX-40CX680 is "B".

Reasons Against

23% smaller display diagonal Edit

Slower motion interpolation frequency Edit
The Panasonic TX-40CX680 is a 200Hz motion interpolation frequency TV. That's 800Hz slower than the Sony KD-49X8308 (1,000Hz). 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.

Narrower horizontal viewing angle Edit
The Panasonic TX-40CX680 is a 176° horizontal viewing angle TV. That's 2° narrower than the Sony KD-49X8308 (178°). 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.

Energy efficiency rating is inferior
The Panasonic TX-40CX680 has an energy efficiency rating of "B", but the Sony KD-49X8308 has a rating of "A".
3 Reasons Against
13mm thicker Edit
The Sony KD-49X8308 is a 60mm thick TV, whereas the Panasonic TX-40CX680 is a 47mm thick TV (13mm thinner). Read more
