Reasons For

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

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 thickness 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.

£40 cheaper
The Panasonic TX-55CX680 is £40 cheaper than the Sony KDL-50W756.
Available from 2 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.
6 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. 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 USB 2.0 port Edit
The Sony KDL-50W756 is a three USB 2.0 port TV, whereas the Panasonic TX-55CX680 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.

Four HDMI ports Edit
The Sony KDL-50W756 has four HDMI ports, however the Panasonic TX-55CX680 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.

81kWh lower annual energy consumption Edit
The Sony KDL-50W756 has an annual energy consumption of 100kWh, however the Panasonic TX-55CX680 is a 181kWh annual energy consumption TV (81kWh 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.

5.8kg lighter Edit
The Sony KDL-50W756 is a 13.7kg heavy TV, whereas the Panasonic TX-55CX680 is a 19.5kg heavy TV (5.8kg 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.

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".
