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.

26% lighter Edit
The Panasonic TX-40CX680 has a weight of 11.5kg. That's 2.9kg lighter than the Sony KD-49X8308 (14.4kg). 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.

6 Reasons For
19% larger screen size Edit
The Sony KD-49X8308 is a 49" TV. That's 9" larger than the Panasonic TX-40CX680 (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.

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. 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.

Two composite video in ports Edit
The Sony KD-49X8308 has two composite video in ports, however the Panasonic TX-40CX680 only has one composite video in port. 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 Edit
The Sony KD-49X8308 has three USB 2.0 ports, however the Panasonic TX-40CX680 only has two USB 2.0 ports. 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 port Edit
The number of HDMI ports on the Sony KD-49X8308 is four, but the Panasonic TX-40CX680 only has three HDMI ports. 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.

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

6 Reasons Against
23% smaller screen size Edit
The Panasonic TX-40CX680 is a 40" TV. That's 9" smaller than the Sony KD-49X8308 (49"). Read more

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
