Reasons For

3 Reasons For
5" larger display diagonal Edit
The Hisense LTDN55K321 has a display diagonal of 55", whereas the Hisense UB50EC591 and the Panasonic TX-50CX700 are both only 50" TVs (5" smaller). 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.

Faster response time Edit
The Hisense LTDN55K321 is a 6.5ms response time TV. That's 2.7ms faster than the Hisense UB50EC591 (). Read more

'Response Time' is the measure of how long it takes an individual pixel to move from active to inactive - therefore how fast it takes the TV to respond to the signal it's receiving and display it on the screen.

Slow response times on a TV mean that signals on fast moving images (such as video games or sports) could clash together, creating blurry images as several slightly different signals attempt to be displayed at once. A TV with faster response times can therefore display fast-moving images sharply and cleanly.

Energy efficiency rating is better
The Hisense LTDN55K321 has an energy efficiency rating of "A", however the Hisense UB50EC591 has a rating of "A" and the Panasonic TX-50CX700 has a rating of "A".
1 Reason For
Better energy efficiency rating
The energy efficiency rating of the Hisense UB50EC591 is "A", however the rating of the Hisense LTDN55K321 is "A" and the rating of the Panasonic TX-50CX700 is "A".
6 Reasons For
3D Edit
The Panasonic TX-50CX700 is a 3D TV, whereas the Hisense LTDN55K321 and the Hisense UB50EC591 are not 3D. 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.

Faster motion interpolation frequency Edit
The Panasonic TX-50CX700 is an 800Hz motion interpolation frequency TV. That's 400Hz faster than the Hisense UB50EC591 (800Hz). 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.

A faster motion interpolation frequency will result in smoother action scenes, less motion blur and a more life like image.

Hugely thinner Edit
Panasonic TX-50CX700 is 46mm thick, but the Hisense LTDN55K321 is an 83mm thick TV (37mm thicker) and the Hisense UB50EC591 is an 82mm thick TV (36mm 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.

Available from 2 shops
A greater number of retailers increases the chances of this TV remaining in stock and also increases the price competition amongst retailers for the product.
48% cheaper to run
The Panasonic TX-50CX700 is £139.41 cheaper to run than the Hisense LTDN55K321 and £83.33 cheaper to run than the Hisense UB50EC591 over five years. Read more
Better energy efficiency rating
The energy efficiency rating of the Panasonic TX-50CX700 is "A", however the rating of the Hisense LTDN55K321 is "A" and the rating of the Hisense UB50EC591 is "A".
