Reasons For

3 Reasons For
93% lower annual energy consumption Edit
The Changhong LED40D2200 is a 64kWh annual energy consumption TV. That's 59kWh lower than the LG 49UH850 (123kWh). 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.

Lighter Edit
The Changhong LED40D2200 is a 6.7kg heavy TV. That's 9.2kg lighter than the LG 49UH850 (15.8kg). 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.

Better energy efficiency rating
The energy efficiency rating of the Changhong LED40D2200 is "A+", however the rating of the LG 49UH850 is "A".
4 Reasons For
19% larger screen size Edit
The LG 49UH850 has a screen size of 49", however the Changhong LED40D2200 is only a 40" TV (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.

60% higher RMS rated power Edit
The LG 49UH850 is a 40W RMS rated power TV. That's 24W higher than the Changhong LED40D2200 (40W). 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.

One more USB 2.0 port Edit
The LG 49UH850 has two USB 2.0 ports, however the Changhong LED40D2200 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.

Thinner Edit
The LG 49UH850 is a 51.5mm thick TV. That's 38.5mm thinner than the Changhong LED40D2200 (51.5mm). 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.
