Reasons For

6 Reasons For
10% larger screen size Edit
The Hisense H55M3300 is a 55" TV. That's 5" larger than the Hisense LTDN50K321 and the Hisense UB50EC591 (50"). 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.

50% faster motion interpolation frequency Edit
The Hisense H55M3300 is an 800Hz motion interpolation frequency TV, and so does the Hisense LTDN50K321. That's 400Hz faster than the Hisense UB50EC591 (400Hz). 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.
