Reasons For

6 Reasons For
Faster motion interpolation frequency Edit
The Samsung UE55JS9000 is a 2,000Hz motion interpolation frequency TV. That's 1,800Hz faster than the Samsung UE55KS9000 (1,000Hz) and 1,000Hz faster than the Sony KD-55X8509 and the Sony KD-55XD8599 (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.

20W higher subwoofer RMS power Edit
The Samsung UE55JS9000 is a 20W subwoofer RMS power TV. That's 20W higher than the Sony KD-55XD8599 (unknownW). Read more

This is a measure of the continuous power (RMS power) produced by a subwoofer.

One more RF port Edit
The Samsung UE55JS9000 is a two RF port TV, whereas the Sony KD-55XD8599 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.

8 Reasons For
40W higher RMS rated power Edit
The Samsung UE55KS9000 has an RMS rated power of 60W, but the Samsung UE55JS9000 is only a 40W RMS rated power TV (20W lower) and the Sony KD-55X8509 and the Sony KD-55XD8599 are both only 20W RMS rated power TVs (40W 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.

Four point one loudspeakers Edit
The Samsung UE55KS9000 has four point one loudspeakers, however the Sony KD-55XD8599 only has two loudspeakers. Read more

The number of loudspeakers is the total number of speakers provided with the TV, either inside the TV casing or as external speakers.

A greater number of speakers will allow for better quality audio and different frequencies. Multiple external speakers will enable to the TV to play surround sound audio.

Common interface connection Edit
The Samsung UE55KS9000 has a common interface connection, however the Samsung UE55JS9000 does not have a common interface connection. Read more

A common interface slot provides compatibility with pay-per-view cards.

A common interface slot allows you to install pay per view cards. For example Sky TV sell pay per cards for watching football and boxing and WWE Network sell cards for watching wrestling.

Newer common interface plus (CI+) version Edit
The Samsung UE55KS9000 has a common interface plus (CI+) version of 1.3, but the Samsung UE55JS9000 and the Sony KD-55XD8599 are both only unknown common interface plus (CI+) version TVs (1.3 older).
30% lower annual energy consumption Edit
The Samsung UE55KS9000 is a 118kWh annual energy consumption TV. That's 35kWh lower than the Samsung UE55JS9000 (143kWh) and 25kWh lower than the Sony KD-55XD8599 (143kWh). 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.

Available from 37 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.
27% cheaper to run
The Samsung UE55KS9000 is £41.89 cheaper to run than the Samsung UE55JS9000, £51.11 cheaper to run than the Sony KD-55X8509 and £31.89 cheaper to run than the Sony KD-55XD8599 over five years. Read more
Better energy efficiency rating
The energy efficiency rating of the Samsung UE55KS9000 is "A+", however the rating of the Samsung UE55JS9000 is "A", the rating of the Sony KD-55X8509 is "A" and the rating of the Sony KD-55XD8599 is "A+".
4 Reasons For
Vastly faster refresh rate Edit
The Sony KD-55X8509 is a 100Hz refresh rate TV, and so does the Sony KD-55XD8599. That's 100Hz faster than the Samsung UE55JS9000 (100Hz). 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.

Two composite video in ports Edit
The Sony KD-55X8509 is a two composite video in port TV, whereas the Sony KD-55XD8599 only has one composite video in port. Read more

We do not know the number of composite video in ports on the Samsung UE55KS9000. 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.

£279 cheaper
The Sony KD-55X8509 costs £799.01 less than the Samsung UE55JS9000, costs £869.01 less than the Samsung UE55KS9000 and costs £279 less than the Sony KD-55XD8599.

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.

2x thinner Edit
The Sony KD-55XD8599 has a thickness of 44mm. That's 46.7mm thinner than the Samsung UE55JS9000 (44mm), 49.3mm thinner than the Samsung UE55KS9000 (44mm) and 16mm thinner than the Sony KD-55X8509 (44mm). 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.

A lot lighter Edit
Sony KD-55XD8599 is 15.1kg heavy, but the Samsung UE55JS9000 is a 21.7kg heavy TV (6.6kg heavier), the Samsung UE55KS9000 is a 17.9kg heavy TV (2.8kg heavier) and the Sony KD-55X8509 is a 19.9kg heavy TV (4.8kg heavier). Read more
