Reasons For

4 Reasons For
Larger display diagonal Edit
The Sony KD-49X8309 has a display diagonal of 49", but the Sony KDL-43W755 is only a 43" TV (6" 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.

20% faster motion interpolation frequency Edit
The Sony KD-49X8309 has a motion interpolation frequency of 1,000Hz, however the Sony KDL-43W755 is only an 800Hz motion interpolation frequency TV (200Hz 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. Motion interpolation technology can sometimes create some unwanted side effects such glitches when the technology suddenly activates during an action scene. Most modern TVs will have an option to switch off the motion interpolation if it is not desired.

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

One more composite video in Edit
The number of composite video ins on the Sony KD-49X8309 is two, but the Sony KDL-43W755 only has one composite video in. Read more

A composite video port is mainly used for connecting older devices to the TV, such as older video cameras or video recorders. Composite video connections can only display images up to a resolutionsof 640 x 480 pixels so the quality of image displayed via a composite video connection will be quite low.

Multiple composite video ports will allow you to connect more than one older video device. However it is very unlikely that you will use the composite video port at all.

Cheaper by £20
The Sony KD-49X8309 is £20 cheaper than the Sony KDL-43W755.
6 Reasons For
41kWh lower annual energy consumption Edit
The Sony KDL-43W755 has an annual energy consumption of 76kWh, however the Sony KD-49X8309 is a 117kWh annual energy consumption TV (41kWh higher). Read more

The annual energy consumption is the total amount of energy that the TV will use over the course of a whole year, given typical usage levels.

A lower annual energy consumption means that it will cost less each year for you to run your TV.

2% thinner Edit
Sony KDL-43W755 is 59mm thick. That's 1mm thinner than the Sony KD-49X8309 (59mm). 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.

3.5kg lighter Edit
The Sony KDL-43W755 is a 10.9kg heavy TV, whereas the Sony KD-49X8309 is a 14.4kg heavy TV (3.5kg heavier). Read more

The weight is the total weight of the TV excluding all packaging.

A lighter weight TV will be easier to move around and to mount on a wall. Some of the larger, very heavy TVs may require lightweight partition walls to be reinforced before the TV could be mounted.

4 shops are selling it
A greater number of shops increases the chances of the product remaining in stock and also increases the price competition amongst retailers for this TV.
36% cheaper to run
Over five years the Sony KDL-43W755 is £49.51 cheaper to run than the Sony KD-49X8309. Read more
Energy efficiency rating is better
The Sony KDL-43W755 has an energy efficiency rating of "A+", however the Sony KD-49X8309 has a rating of "A".

Reasons Against
