The LG 55UH661 is a 16.5kgg heavy TV. That's 1.7g lighter than the LG 55UH668 (19.3kgg) and 2.8g lighter than the LG 55UH750 (19.3kgg). Read more

The weight is the total weight of the TV excluding all packaging.

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 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 93% based on 17 reviews, however the LG 55UH750 has an average rating of 65% (based on 4 reviews).
2 Reasons For
One more RF port Edit
The LG 55UH668 has two RF ports (as does the LG 55UH750), however the LG 55UH661 only has one RF port. Read more

RF stands for Radio Frequency and an RF port is an older type of input connector for TVs which is most commonly use for connecting cable TV and satellite TV feeds directly to the TV.

Multiple RF ports will allow you to connect multiple RF feeds to the TV at the same time. For example, if the TV has a built in satellite TV decoder then you could connect 2 different satellite dishes to the TV.

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+".

Lower annual energy consumption Edit
The LG 55UH750 is a 107kWhkWh annual energy consumption TV. That's 4kWh lower than the LG 55UH661 (107kWhkWh) and 8kWh higher than the LG 55UH668 (107kWhkWh). 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.

19% thinner Edit
The LG 55UH750 has a thickness of 51.2mmmm, however the LG 55UH661 and the LG 55UH668 are both 60.9mmmm 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.
