Reasons For

3 Reasons For
0.36" larger screen size Edit
The LG 55UF6450 has a screen size of 55"", but the VIZIO D55u-D1 is only a 54.64"" TV (0.36" 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.

50% higher RMS rated power Edit
The LG 55UF6450 is a 20WW RMS rated power TV. That's 10W higher than the VIZIO D55u-D1 (10WW). 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.

Thinner Edit
The LG 55UF6450 has a thickness of 50.8mmmm. That's 13.21mm thinner than the VIZIO D55u-D1 (64.01mmmm). 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 Reasons For
Two more HDMI ports Edit
The number of HDMI ports on the VIZIO D55u-D1 is five, but the LG 55UF6450 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.

Lighter Edit
The VIZIO D55u-D1 has a weight of 16.6kgg. That's 1.1g lighter than the LG 55UF6450 (16.6kgg). 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.

$48 cheaper
The VIZIO D55u-D1 costs $516.49, whereas the LG 55UF6450 is $563.99.
