LG UF6430 Review – 4k Ultra HD Smart LED TV Series – ( 43UF6430, 49UF6430, 55UF6430 )
The UF6430 comes in three sizes (43 inches, 49 inches and 55 inches) and features a native 4K UHD resolution producing stunningly sharp, crisp and colourful visuals which display beautifully and accurately even at wider viewing angles. The TV also features LG’s proprietary 4K-upscaling technology allowing non 4K content to look (almost) as good as native 4K content.
The UF6430 runs on Web OS 2.0, one of the most easy to use, intuitive and visually appealing operating systems we’ve seen on the market so far. To top it off the 4k TV is Energy Star Qualified making it approximately over 24% more energy efficient than non-certified TV’s.
The UF6430 is not without its faults though. Firstly, although it has a 120Hz effective refresh rate, it actually has a 60Hz native refresh rate which may result in some motion handling disappointments among AV enthusiasts. Secondly, the TV seems to suffer from a design fault in that the TV’s legs are positioned quite far apart so may be unsuitable for a number of TV cabinets and viewing areas.
Third and finally, the 4k TV does not seem very feature rich as it lacks some features such as LED Plus (Local Dimming) which the UF7700 and UF8600 have. And Cinema 3D that the UF8600 and UF9500 have. However, we believe the UF6430 makes up for it’s somewhat lack of features by doing the core thing, displaying beautiful visuals, very well indeed.
Real 4K UHD Performance – The UF6430 has a full 4K UHD resolution (3840 x 2160), unlike many TV’s in it’s price range that often have a resolution close to 4K but don’t offer the full 4K resolution. As you can imagine, when 4K content is playing on the TV’s 4K IPS screen it looks sublime. Crisp, colourful, sharp and almost surreal image quality.
High quality 4K up-scaler – The savvy among you may read the above paragraph and be thinking; sure the 4K resolution screen is going to produce stunning visuals when you are playing native 4K content, but there is hardly any of that native content out there at the moment. Fret not, because this is where the TV’s 4K up-scaler comes in, and is in our opinion one of the highlights of the TV.
The UF6430’s 4K Up-scaler uses proprietary multi-step data analysis which significantly enhances the detail and sharpness of everything you watch ( HD and standard definition) and makes it all look near to 4K quality.
Web OS 2.0 – In our opinion a TV’s operating system has the ability to make or break your viewing experience. What’s the point in having a TV that is full to the brim with features and can display stunning images when you spend most of your time fiddling with it and trying to get it to do what you want? Thankfully, the UF6430’s operating system is easy to use, intuitive and visually stunning.
Select and switch between content seamlessly and frictionlessly with web OS 2.0’s nimble, light menu system, always find what you are looking for with powerful search built in, and discover new content easily as you can flick through the catalogues of multiple streaming services and apps super efficiently.
Energy Efficient – A large number of the TV’s out there that offer a real 4K resolution understandably sip a lot of electricity to deliver this. With the UF6430 however that is less of a worry. The TV is fully Energy Star Qualified. What this essentially means is that the TV has met stringent energy efficient guidelines set forth by the US Environmental Protection Agency and the Department of Energy. TV’s that have been Energy Star certified are typically over 24% more energy efficient than non- certified TV’s. Energy certified TV’s save energy in “sleep”, “idle” and “on” modes.
Variety Of Sizes – How many times have you come across a spectacular TV that you have been incredibly close to buying only to find out it doesn’t come in a size that is optimum for the room you want to place it in. It’s happened to us a fair few times, so we’re sure some of you have experienced this issue.
Luckily this isn’t a problem with the UF6430. It comes in three glorious sizes. 43 inches, 49 inches and 55 inches. We think this is a really good move from LG as the size of a TV in relation to the room can really affect the viewing quality, something we hope more manufacturers will take into account with their future releases.
Tru Motion – LG’s Tru-Motion technology markedly enhances frame rates to significantly reduce blur which results in crisper, sharper visuals – the benefits of this can really be seen if you are watching fast action footage. Sports fans rejoice!
We’ve come across some true 4K resolution TV’s in the past that look great when displaying footage like news and sitcoms (generally slow moving stuff) but start to look weak when displaying sports or action movies (generally fast moving stuff), that’s not the case with the UF6430.

As can be seen from the above, there are many great things about the UF6430, however, unfortunately the TV is not without it’s faults and downsides which we will cover below.
60Hz not 120Hz refresh rate – As mentioned above, the UF6430 has a feature called Tru-Motion which enhances frame rates with the purpose of reducing blurring and thus generating a crisper image when viewing video, especially fast motion video like action movies and sports.
This is all well and good, however there is an issue. TruMotion natively operates at 60Hz and not the 120Hz frequently highlighted and touted on various sites including LG’s official site. The LG site states the TV has “TruMotion 120Hz”, however stripped down without the added image processing, it’s in fact a native 60Hz you will be getting, not 120Hz. S0 60Hz is the true refresh rate of the TV.
In other words it is effectively 120Hz, but natively 60Hz. This may not mean much to many, but for those expecting a native 120Hz refresh rate will be slightly disappointed with this.
Design Flaw – The TV’s exterior is exquisite, there is no denying that, however there does seem to have been a small design oversight by the LG team. The issue might not be a big deal to many, but can be a deal breaker for the ones it does effect so we thought it would be worth mentioning.
So what are we talking about? Well, the legs. The legs I hear you ask, yes the legs. Allow us to explain. Instead of the legs being inside the width of the TV, the legs in fact span the outside edge on each side. This means that many peoples TV stands may be too narrow to accommodate the TV. If you take a closer look at the space between the legs of the TV in the pictures above then what we are talking about should become clearer.
If you have a large TV cabinet or TV area this will be no issue at all, but if not it’s worth taking a closer look at the dimensions of where you are planning to place the TV to ensure there will no issues if you go ahead and purchase the UF6430.
Not That Feature Rich – The UF6430 is lacking somewhat in features. It has no LED Plus (Local Dimming) like the UF7700 and UF8600 do. It also doesn’t have Cinema 3D like the UF8600 and UF9500.
The lack of these features is slightly disappointing, but it can be argued that the lack of features is reflected in the UF6430’s price and positioning. Essentially, if you want those extra features you have to shell out more for the higher end models in this range. However, despite this we can’t help thinking that this TV could have been a bit more feature rich.
What redeems it though is that what the UF6430 does have it executes perfectly. The quality of the images that this 4K IPS display in the UF6430 produces are absolutely gorgeous; crisp, sharp, accurate and we can’t fault them in any way. And perhaps the lack of features are made up by slightly by how much Web OS 2.0 has to offer.

The UF6430 is not the most feature packed but what it does do, and what we believe is the most important job a TV needs to do (i.e. produce stunning, sharp accurate images), it does incredible well.
As shown above there are many great things about this TV but we will elaborate on what we feel are its two biggest highlights below.
Real 4K UHD Performance – The UF6430 has a full 4k UHD resolution at (3840 x 2160). When the UF6430 is playing native 4K content (which there isn’t a lot of at the moment but is growing all the time) on its 4K resolution IPS screen the results are sublime. Crisp, colourful, sharp and almost surreal image quality.
High quality 4K up-scaler – As we mentioned in the above paragraph, there isn’t a lot of native 4K content out there at the moment but it’s growing all the time. Not having a load of 4K content to watch to make the most of out of the TV is not an issue with the UF6430 though, because this is where the TV’s 4K up-scaler comes in.
The 4K Up-scaler uses proprietary LG multi-step data analysis which noticeably enhances the detail and sharpness of everything you watch (HD and standard definition) and makes it all look almost as good as native 4K content.

The UF6430 features an IPS screen with full 4K UHD resolution. IPS 4K produces true colours that remain consistently accurate at even wider viewing angles. The TV has a true 4K resolution powered by a tru-4K engine. We are talking four times that of Full HD, a real 3840 x 2160 – no “equivalents” or “close to’s”.
The TV also features “Tru-Motion” technology which noticeably enhances frame rates to significantly reduce blur resulting in crisper, sharper visuals. The benefits of this can really be seen if you are watching fast action footage like car chase movies or sports.
The benefits of Tru-Motion really can’t be emphasised enough. We have come across some true 4K resolution TV’s in the past that look great when displaying slow moving content (news, sitcom) but start to look weak when watching sports or action movies, that’s not the case with the UF6430.
The UF6430 also features a 4K Up-scaler which cleverly utilises LG’s proprietary multi-step data analysis which significantly enhances the detail and sharpness of everything you watch ( HD and standard definition) and makes it all look near to 4K quality. So even non 4K footage will look sublime on the UF6430.
Overall, the display is the real highlight of this TV. It produces crisp, sharp, colourful accurate images regardless of what you are watching. Be it an action movie or a wild life documentary, whether it be true 4K footage or standard definition footage that has been digitally up-scaled to 4K.
There aren’t really any downsides when it comes to the display unless you consider features that are omitted/not present in this set that have been seen in other LG TV’s in a somewhat similar price bracket. Things like 3D capability or better contrast management features.
RF in (Antenna/Cable) (1, Rear) / Component Video In (1, Rear) / Composite In (AV) (Shared w/ composite) / Optical Output ( 1, Rear) / HDMI ( 3, Rear) / USB 3.0/2.0 ( 0 / 1 - side) / LAN (1, Rear).
The 43 inch version 43UF6430 is currently retailing for $397.99 and the 49 inch version 49UF6430 for $497.99 on Amazon. The pricing is fair compared to typical 4k TVs, with this range we recommend going with the Samsung UN50JS7000 or the Vizio M55-V2.

We have mentioned the shortcomings of the TV in detail above however we felt it would be useful to summarise them below.
Firstly, although the UF6430 has a 120Hz effective refresh rate, it actually has a 60Hz native refresh rate which may result in some motion handling disappointments. Secondly, the TV appears to have a (significant for some) design fault in that its legs are positioned very far apart so the TV may be unsuitable for a number of TV cabinets and viewing areas.
Finally, the TV does not seem very feature rich. It doesn’t have things like LED Plus (Local Dimming) which the UF7700 and UF8600 have. It also doesn’t have Cinema 3D that the UF8600 and UF9500 have. However, we believe the UF6430 makes up for apparent lack of features by doing the core thing, displaying beautiful stunning visuals, very well indeed.
