Reasons For

4 Reasons For
50% higher RMS rated power Edit
The LG 55UF6450 is a 20W RMS rated power TV, and so does the Samsung UN55HU6840. That's 10W higher than the VIZIO D58u-D3 (10W). 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.

Internet TV Edit
The LG 55UF6450 supports internet TV, however the Samsung UN55HU6840 does not. Read more

Internet TVs allow you to access the internet directly through your TV. Connect your TV to your local network though WiFi or an ethernet cable.

Internet TVs let you watch movies and TV on the internet by connecting directly to services such as BBC iPlayer and YouTube without a computer.

Thinner Edit
The LG 55UF6450 has a depth of 50.8mm, and so does the Samsung UN55HU6840. That's 21.32mm thinner than the VIZIO D58u-D3 (72.12mm). 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.

4 shops are selling it
A greater number of sellers increases the price competition amongst retailers for the product and also increases the chances of this TV remaining in stock.
4 Reasons For
Faster motion interpolation frequency Edit
The Samsung UN55HU6840 is a 240Hz motion interpolation frequency TV. That's 120Hz faster than the LG 55UF6450 (). 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.

10W higher RMS rated power Edit
The Samsung UN55HU6840 has an RMS rated power of 20W (as does the LG 55UF6450), but the VIZIO D58u-D3 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 lot thinner Edit
Samsung UN55HU6840 is 50.8mm thick (as does the LG 55UF6450), but the VIZIO D58u-D3 is a 72.12mm thick TV (21.32mm 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.

$65 cheaper
The Samsung UN55HU6840 costs $64.99 less than the LG 55UF6450.
3 Reasons For
Slightly larger display diagonal Edit
The VIZIO D58u-D3 has a display diagonal of 57.5", however the LG 55UF6450 is only a 55" TV (2.5" smaller) and the Samsung UN55HU6840 is only a 54.6" TV (2.9" 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.

Local dimming Edit
The VIZIO D58u-D3 features local dimming, whereas the LG 55UF6450 does not. Read more

This means that LEDs can be controlled individually (or in clusters) to control the level of light/color intensity in a given part of the screen.

$0.49 cheaper to run
Over five years the VIZIO D58u-D3 is $0.49 cheaper to run than the Samsung UN55HU6840. Read more
