Reasons For

4 Reasons For
5" larger screen size Edit
The Hisense LTDN55K321 has a screen size of 55", whereas the Hisense UB50EC591 and the Panasonic TX-50CX700 are both only 50" TVs (5" 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.

Faster response time Edit
The Hisense LTDN55K321 is a 6.5ms response time TV. That's 2.7ms faster than the Hisense UB50EC591 ().
Four HDMI ports Edit
The Hisense LTDN55K321 has four HDMI ports, and so does the Hisense UB50EC591, however the Panasonic TX-50CX700 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.

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".
3 Reasons For

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 Hisense UB50EC591 is "A", however the rating of the Hisense LTDN55K321 is "A" and the rating of the Panasonic TX-50CX700 is "A".
8 Reasons For
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. Motion interpolation technology can sometimes create some unwanted side effects such glitches when the technology suddenly activates during an action scene. Most modern TVs will have an option to switch off the motion interpolation if it is not desired.

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

2x lower annual energy consumption Edit
The Panasonic TX-50CX700 is a 126kWh annual energy consumption TV. That's 136.8kWh lower than the Hisense LTDN55K321 (126kWh) and 85.7kWh lower than the Hisense UB50EC591 (126kWh). 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.

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.
