Reasons For

LG 55UF6450 VIZIO D55u-D1
4 Reasons For
0.36" Larger Display Diagonal
The LG 55UF6450 has a display diagonal of 55", but the VIZIO D55u-D1 is only a 54.64" TV (0.36" smaller).

‘Display Diagonal’ is the measure of the size of the TV screen from top-left to bottom-right corner, 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. TVs with a bigger display diagonal allow you to make the most of HD content and are great for watching movies. 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.

Read more Read less | Edit
50% Higher RMS Rated Power
The LG 55UF6450 is a 20W RMS rated power TV. That's 10W higher than the VIZIO D55u-D1 (10W).

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.

Read more Read less | Edit
Thinner
The LG 55UF6450 has a thickness of 50.8mm. That's 13.21mm thinner than the VIZIO D55u-D1 (64.01mm).

The thickness of a 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.

Energy Efficiency

Running Costs Over 5 Years

TV running costs calculated based on an average of 5 hours of use per day. The running cost comprises the electricity cost when using the TV and the electricity standby cost. Compare all energy saving TVs.

Environmental Impact

We have calculated the amount of CO2 that will be generated by running each of these TVs for 5 years. We have then converted that into the number of tree seedlings that you would need to plant and grow for 10 years in order to offset that amount of CO2.
