Reasons For

4 Reasons For
Larger display diagonal Edit
The LG 55UH668 is a 55" TV. That's 5" larger than the Panasonic TX-50DX750 (50"). Read more

‘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.

£9 cheaper
The LG 55UH668 costs £489.99, whereas the Panasonic TX-50DX750 is £499.00.

The LG 55UH668 is £46.08 cheaper to run than the Panasonic TX-50DX750 over five years. Read more
Higher energy efficiency rating
The energy efficiency rating of the LG 55UH668 is "A+", but the rating of the Panasonic TX-50DX750 is "A".
4 Reasons For
3D Edit
The Panasonic TX-50DX750 is 3D, but the LG 55UH668 is not. Read more

‘3D’ describes whether the TV can display 3D movies and programmes. Requires compatible 3D glasses to properly function.

3D technology has become increasingly popular as the amount of 3D film and TV content has increased dramatically in recent years. All 3D TVs will also display regular 2D content and most will allow you to switch on and off the 3D effect on 3D content. 3D compatible TVs allow you to watch 3D content. For most TVs you will need to wear special glasses to see the 3D effect.

Significantly faster high frequency rate Edit
The Panasonic TX-50DX750 is a 1,800Hz refresh rate TV, whereas the LG 55UH668 is only a 100Hz refresh rate TV (1,700Hz slower). Read more

The refresh rate (also known as the high frequency rate) is the number of times that the image on the screen is refreshed per second. It affects how smoothly motion on the screen appears.

Action will appear smoother on TVs with a higher frequency rate: a TV with a high frequency rate of 30Hz refreshes the image on the screen once every 30 times every second. However 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.

53% thinner Edit
The Panasonic TX-50DX750 has a depth of 40mm. That's 20.9mm thinner than the LG 55UH668 (40mm). 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.

12 shops are selling it
A greater number of shops increases the price competition amongst retailers for the product and also increases the chances of this TV remaining in stock.
