Reasons For

3 Reasons For
2.8kg lighter Edit
The LG 55UH661 is a 16.5kg heavy TV. That's 1.7kg lighter than the LG 55UH668 (19.3kg) and 2.8kg lighter than the LG 55UH750 (19.3kg). 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 86% based on 44 reviews, however the LG 55UH750 has an average rating of 65% (based on 4 reviews).
4 Reasons For
One more RF ports quantity Edit
The LG 55UH668 has two RF ports quantitys (as does the LG 55UH750), however the LG 55UH661 only has one RF ports quantity. 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.

12kWh lower annual energy consumption Edit
The LG 55UH668 is a 99kWh annual energy consumption TV. That's 12kWh lower than the LG 55UH661 (107kWh) and 8kWh lower than the LG 55UH750 (107kWh). 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.

Cheaper to run by $9.52
The LG 55UH668 is $9.52 cheaper to run than the LG 55UH661 and $5.95 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+".
4 Reasons For
700 bigger PMI (Picture Mastering Index) Edit
The LG 55UH750 has a PMI (Picture Mastering Index) of 1,900, but the LG 55UH661 is only a 1,700 TV (200 smaller) and the LG 55UH668 is only a 1,200 TV (700 smaller).
One more RF ports quantity Edit
The LG 55UH750 has two RF ports quantitys (as does the LG 55UH668), however the LG 55UH661 only has one RF ports quantity. 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.

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.

Superior energy efficiency rating
