Reasons For

2 Reasons For
Better energy efficiency rating
The energy efficiency rating of the LG 55UH661 is "A+", however the rating of the LG 55UH668 is "A+" and the rating of the LG 55UH750 is "A+".
User reviews are vastly better
The LG 55UH661 has an average user review score of 87% based on 45 reviews, however the LG 55UH750 has an average rating of 65% (based on 4 reviews).
3 Reasons For
Faster high frequency rate Edit
The LG 55UH668 is a 100Hz refresh rate TV. That's 50Hz faster than the LG 55UH661 (). 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.

Cheaper to run by $10.16
The LG 55UH668 is $10.16 cheaper to run than the LG 55UH661 and $6.27 cheaper to run than the LG 55UH750 over five years. Read more
Superior energy efficiency rating
The energy efficiency rating of the LG 55UH668 is "A+", whereas the rating of the LG 55UH661 is "A+" and the rating of the LG 55UH750 is "A+".
2 Reasons For
19% thinner Edit
The LG 55UH750 has a depth of 51.2mm, however the LG 55UH661 and the LG 55UH668 are both 60.9mm thick TVs (9.7mm 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.
