Reasons For

5 Reasons For
3D Edit
The Panasonic TX-40AX630 is a 3D TV, whereas the Sony KD-49X8309 is not 3D. Read more

3D technology has become increasingly popular as the amount of 3D film and TV content has increased dramatically in recent years. All 3D TVs will also display regular 2D content and most will allow you to switch on and off the 3D effect on 3D content. Most 3D TVs require you to wear special 3D glasses in order to view the content in 3D, however some of the newer 3D TVs require no 3D glasses at all. Of those TVs that do require glasses, there are two main types of 3D technology: passive and active. Passive 3D uses glasses similar to those that you wear in the cinema. The glasses have polarised lenses which ensure that the correct image is displayed to each eye. The main advantage of passive 3D is that the glasses are very light and comfortable to wear, but it can result in a less bright image. Active 3D uses battery powered glasses which control active shutters in each lens. These shutters constantly open and close very quickly in sync with two different images that are being displayed by the TV. This ensures that the correct image is displayed to each eye. The main advantage of active 3D is that the image is brighter, however the glasses are heavier and more expensive.

3D compatible TVs allow you to watch 3D content. For most TVs you will need to wear special glasses to see the 3D effect.

17% faster high frequency rate Edit
The Panasonic TX-40AX630 has a high frequency rate of 1,200Hz. That's 200Hz faster than the Sony KD-49X8309 (1,000Hz). Read more

The refresh rate is also known as the high frequency rate and it affects how smooth motion on the screen appears. The high frequency rate is the number of times that the image on the screen is refreshed per second. A TV with a high frequency rate of 30Hz refreshes the image on the screen once every 30 times every second. A TV with a high frequency rate of 60Hz would refresh the image on the screen 60 times every second which means that action scenes would appear smoother.

The high frequency rate is also known as the refresh rate and it affects how smooth motion on the screen appears. Action will appear smoother on TVs with a higher frequency rate.

Faster motion interpolation frequency Edit
The Panasonic TX-40AX630 is a 1,200Hz motion interpolation frequency TV. That's 200Hz faster than the Sony KD-49X8309 (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. 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.

15% lower annual energy consumption Edit
The Panasonic TX-40AX630 is a 102kWh annual energy consumption TV. That's 15kWh lower than the Sony KD-49X8309 (117kWh). 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.

A greater number of stores increases the chances of this TV remaining in stock and also increases the price competition amongst retailers for the product.
6 Reasons For
19% larger display diagonal Edit
The Sony KD-49X8309 is a 49" TV. That's 9" larger than the Panasonic TX-40AX630 (49"). 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.

Two composite video ins Edit
The Sony KD-49X8309 has two composite video ins, however the Panasonic TX-40AX630 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.

Three USB 2.0 ports quantitys Edit
The Sony KD-49X8309 has three USB 2.0 ports quantitys, however the Panasonic TX-40AX630 only has two USB 2.0 ports quantitys. Read more

USB ports are useful for displaying on your TV photos / videos or playing music that is stored on USB key drives. The USB port can also be used for charging devices from your TV (as long as it's switched on), and for installing software updates on the TV.

More USB ports will allow you to connect more USB devices to the TV simultaneously without needing to continuous plug in and unplug cables.

One more HDMI ports quantity Edit
The number of HDMI ports quantitys on the Sony KD-49X8309 is four, but the Panasonic TX-40AX630 only has three HDMI ports quantitys. Read more

The HDMI ports quantity is the number of ports that the TV has that will accept a HDMI cable. HDMI is the most common type of cable used to connect modern TVs, DVD players, games consoles etc.

A greater number of HDMI ports will allow you to permanently connect more devices to the TV and will reduce the need to reach around the back of the TV to unplug and plug in cables when switching between devices.

£150 cheaper
The Sony KD-49X8309 costs £449.00, whereas the Panasonic TX-40AX630 is £599.00.
Higher energy efficiency rating
The energy efficiency rating of the Sony KD-49X8309 is "A", but the rating of the Panasonic TX-40AX630 is "B".
