Reasons For

6 Reasons For
25W higher RMS rated power Edit
The Samsung UN55KS8000 has an RMS rated power of 40WW, but the Sony XBR-55X850 is only a 20WW RMS rated power TV (20W lower) and the VIZIO M55-C2 is only a 15WW RMS rated power TV (25W 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.

Three USB 2.0 ports Edit
The Samsung UN55KS8000 is a three USB 2.0 port TV, and so does the Sony XBR-55X850, whereas the VIZIO M55-C2 only has one USB 2.0 port. 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 processor cores Edit
The number of processor cores on the Samsung UN55KS8000 is four, but the VIZIO M55-C2 only has two processor cores. Read more

We do not know the number of processor cores on the Sony XBR-55X850. It is possible that it does not have any processor cores.

A lot thinner Edit
Samsung UN55KS8000 is 43.18mmmm thick, but the Sony XBR-55X850 is a 59.94mmmm thick TV (16.76mm thicker) and the VIZIO M55-C2 is a 63.75mmmm thick TV (20.57mm 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.

2.5g lighter Edit
The Samsung UN55KS8000 is a 17.4kgg heavy TV. That's 2.5g lighter than the Sony XBR-55X850 (17.9kgg) and 0.5g lighter than the VIZIO M55-C2 (17.9kgg). 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.

Available from 2 shops
A greater number of retailers increases the chances of this TV remaining in stock and also increases the price competition amongst retailers for the product.
5 Reasons For
A bit larger screen size Edit
The Sony XBR-55X850 has a screen size of 55"" (as does the VIZIO M55-C2), whereas the Samsung UN55KS8000 is only a 54.6"" TV (0.4" 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.

Hugely faster motion interpolation frequency Edit
The Sony XBR-55X850 has a motion interpolation frequency of 960HzHz, but the Samsung UN55KS8000 is only a 240HzHz motion interpolation frequency TV (720Hz 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.

Three RF ports Edit
The number of RF ports on the Sony XBR-55X850 is three, but the VIZIO M55-C2 only has one RF port. Read more

RF stands for Radio Frequency and an RF port is an older type of input connector for TVs which is most commonly use for connecting cable TV and satellite TV feeds directly to the TV.

Multiple RF ports will allow you to connect multiple RF feeds to the TV at the same time. For example, if the TV has a built in satellite TV decoder then you could connect 2 different satellite dishes to the TV.

One more composite video in port Edit
The Sony XBR-55X850 is a two composite video in port TV, whereas the VIZIO M55-C2 only has one composite video in port. Read more

We do not know the number of composite video in ports on the Samsung UN55KS8000. It is possible that it does not have any composite video in ports.

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.

Two more USB 2.0 ports Edit
The Sony XBR-55X850 is a three USB 2.0 port TV (as does the Samsung UN55KS8000), whereas the VIZIO M55-C2 only has one USB 2.0 port. 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.

4 Reasons For
Larger screen size Edit
The VIZIO M55-C2 is a 55"" TV, and so does the Sony XBR-55X850. That's 0.4" larger than the Samsung UN55KS8000 (55""). 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.

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.

One more HDMI port Edit
The number of HDMI ports on the VIZIO M55-C2 is five, but the Sony XBR-55X850 only has four 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.

$399 cheaper
The VIZIO M55-C2 costs $599.00, whereas the Samsung UN55KS8000 is $1,097.00 and the Sony XBR-55X850 is $998.00.
User reviews are hugely better
Based on 1 review, the VIZIO M55-C2 has an average user review score of 100%, but the Sony XBR-55X850 has an average rating of 60% (based on 1 review).
