My take on LG 43UK6300


The LG 43UK6300 is a decent smart 4K TV that offers adequate display performance. Furthermore, the television is outfitted with a good number of ports and has a brilliant easy-to-use webOS. Unfortunately, the television’s display lacks local dimming and isn’t bright enough.



  • Good viewing angles
  • Adequate port selections
  • Low input lag
  • Fast response time


  • Lacks bass
  • Mediocre contrast ratio
  • No local dimming
  • Poor brightness

LG 43UK6300: At First Glance

As one of the top manufacturers of television in the industry, LG has released numerous models of TV that have indeed put smiles on users’ faces.

Therefore, in this article, we’ll be reviewing one of LG’s television – the LG 43UK6300. This television is a smart television released in 2018 that offers a 4K display.

Furthermore, the LG 43UK6300 is loaded with useful features which I am sure you will love to learn about. Hence, to know these features, read along as we proceed to other sections of this review.

LG 43UK6300: Design, Dimension, and Weight

The LG 43UK6300 doesn’t come with an elegant look, it features a plain and simple design. To give more details, the bezels of the television are built with glossy-black plastic and they are not particularly thin.

Specifically, these bezels are about 19 mm thick. However, the bezels are not that thick to the extent of causing an obstruction when viewing the television.

Besides, at the center of the bottom bezel, there is an “LG” logo.

Moving on, the LG 43UK6300 comes with a pair of V-shaped legs. Like the bezels, these legs are made of plastic and they are set to the extreme edges of the TV.

Hence, you’ll need a fairly large table to place the television whenever it isn’t wall-mounted. On the plus side, the legs are very sturdy and support the television to stand firmly.

Having discussed the front view of this television, now let us turn around to its rearview. To start with, the back cover of the LG 43UK6300 has a plain design with few dents.

Furthermore, the build material of the back cover is plastic with the bottom part thicker than the top part. Unfortunately, the LG 43UK6300 doesn’t have any form of cable management on its back.

Hence, cables connected to the television might get messy if not organized manually. On the bright side, you will find 200 x 200 VESA holes on the TV’s back for wall-mounting the television.

However, when you mount the LG 43UK6300 on the wall, it will bulge out and look somewhat awkward. This is because the back cover of the television is somewhat thick.

That said, for dimension and weight, the LG 43UK6300 measures 977 x 80.8 x 575 mm (W x D x H) and weighs 8300 g. In comparison with the Samsung NU7100, the LG 43UK6300 is lighter but thicker.

Specifically, the 43-inch Samsung NU7100 weighs 9600 g and measures 970.2 x 58.8 x 563.2 mm (W x D x H).

Hence, to end this design review section, I will rate the LG 43UK6300 a seven out of ten.

LG 43UK6300: Display Features and Picture Quality

The LG 43UK6300 boasts a 43-inch display with an amazing 4K UHD (3840 x 2160) resolution. Due to the fact that this television’s display offers 4K resolution, it should be able to deliver crisp and colorful pictures.

Moreover, as a 4K resolution display, the display is about four times better and sharper than the conventional HD resolution display.

The next display feature of the LG 43UK6300 that I will talk about in this section is its contrast ratio. Let me start by explaining what the term “contrast ratio” means.

Contrast ratio refers to the ratio between the brightest whites and deepest blacks of a display. Furthermore, a high contrast ratio implies that the display will be able to generate deep blacks.

Sadly, the LG 43UK6300’s 43-inch display features a mediocre contrast ratio of 1096:1. Thus, the display will not be able to produce deep blacks.

Practically, blacks on the display will look grayish. As a result, the LG 43UK6300 isn’t the best choice for watching movies with plenty of dark scenes such as horror movies.

In addition to its mediocre contrast ratio, the LG 43UK6300 lacks local dimming which would enhance its contrast ratio. To be more specific, the local dimming is a feature that improves a display’s contrast ratio and black level by dimming backlight zones.

Hence, with this feature, blacks on the display should look darker than they would without the feature. Unfortunately, as mentioned earlier, the television’s display lacks local dimming.

Another not-so-good aspect of the LG 43UK6300’s display is its peak brightness. Specifically, the display measures a peak brightness of 191 nits which is quite poor.

As a result, the LG 43UK6300 isn’t good for watching movies in a bright or well-lit room. As a matter of fact, the display’s brightness is so poor that the television may struggle in moderately-lit rooms.

On a bright note, the LG 43UK6300 handles reflection pretty well. This is a result of the semi-gloss coating on its display which reduces the density of light and reflection.

Moving on, the LG 43UK6300’s display supports HDR (High Dynamic Range) formats such as 4K Active HDR, HDR 10, and HLG(Hybrid Log-Gamma). With HDR, the picture quality of the television’s display will be very realistic, lifelike, and bright when viewing HDR-supported content.

HDR-supported content is usually found on streaming platforms such as Netflix, Hulu, and Amazon Prime Video.

In addition to supporting HDR, the LG 43UK6300’s display offers wide viewing angles. This is because the display is made with an IPS (In-Plane Switching) panel.

As a result, there won’t be picture distortion when viewing the television from extreme angles or off-center. Thus, the LG 43UK6300 is ideal for a large room setting.

Having said all that, let us now discuss the display’s response time. For a brief explanation, response time is how fast a display can transition from one color to another.

That said, the LG 43UK6300’s display comes with a decently fast response time of 15 milliseconds. Thus, with a response time as fast as this, the television should be ideal for watching fast-motion content like sports, action movies, and racing games.

In addition to its fast response time, the LG 43UK6300’s display offers a low input lag. To be more specific, the display has a low input lag of 11.8 milliseconds.

If you are wondering what input lag is, it is the time that a display takes to register signal input. As a result, the LG 43UK6300 is suitable for playing video games and can also serve as a PC monitor.

In summary, the LG 43UK6300 offers a 4K display that is great for gaming and watching fast-motion content. However, the display lacks local dimming, has a low contrast ratio, and isn’t bright enough.

Therefore, the LG 43UK6300 deserves a rating of seven out of ten in this display review section.

LG 43UK6300: Sound Features

The LG 43UK6300 comes with a pair of built-in 2CH 10-watts speakers. With these speakers, the television will be able to deliver a total sound output of 20-watts.

That means the television will be able to produce decently-loud sounds and decent sound quality. However, the television doesn’t have a subwoofer, which implies that it won’t be able to produce an adequate amount of bass.

As a result, the LG 43UK6300 isn’t the best television for watching bass-heavy movies or playing bass-heavy songs. Therefore, in order to get the right amount of bass, you should consider buying a soundbar.

On a positive note, the television’s speakers produce low sound frequencies, which means they will be able to deliver clear dialogue. In case you’re wondering, dialogue refers to the conversation between more than one character in a movie.

Another thumbs up for the LG 43UK6300’s speakers is that they are able to deliver fantastic surround sound. Hence, you will be able to enjoy an immersive audio quality when viewing the television.

Let us now move on to discuss the distortion performance of the LG 43UK6300. To do so, we will be highlighting the television’s result on a THD (Total Harmonic Distortion) test.

Briefly, THD is a sound test that measures the amount of distortion that a sound system is capable of generating. Furthermore, on this test, a score of 1% or less depicts that the sound system produces minimal distortion.

Thankfully, the LG 43UK6300 delivered a score of 0.570% on the THD test. Thus, at a maximum or medium volume level, the television will generate a minimal and less-audible amount of distortion.

To be clear, distortion in this context refers to the alteration of sound frequencies which results in a sound system producing sub-par sound output.

After much consideration, I’ll be rating the LG 43UK6300 an eight out of ten in this sound features review section.

LG 43UK6300: Ports and Connectivity Features

The LG 43UK6300 features a good amount of ports which are all located on its back panel. To give more details, these ports on the television’s back are divided into two groups.

The first group of ports is directly on the TV’s back while the second group is left-facing. Among the left-facing port, you will find two HDMI ports with one that is compatible with ARC (Audio Return Channel).

Thus, with the HDMI-ARC port, users will be able to connect a soundbar to the television. In addition to the HDMI ports, there is also a USB port among the left-facing ports.

For the backward-facing ports, there is an optical digital out, another USB port, and another HDMI port. Other ports that you will find among the backward-facing ports are an AV port, RF connector, and an Ethernet port.

In terms of wireless connectivity, the LG 43UK6300 comes with an in-built 802.11 a/b/g/n/ac WiFi and Bluetooth version 4.2.

Moving on, the LG 43UK6300 features a standard LG remote control. This remote is made of plastic and has a matte-black finish with a reasonable amount of buttons.

These buttons include a search button, a setting button, and a power button at the top part of the remote. Also, the remote features a full number pad and a plus-shaped navigation button at the center.

In addition to that, the LG 43UK6300’s remote control has two dedicated buttons for quick access to Netflix and Amazon Prime Video. However, the remote lacks a built-in mic for voice input.

Nevertheless, the television support LG’s magic remote control. As a result, if you purchase the magic remote which features a built-in mic, you will be able to control the television with your voice.

In conclusion, the LG 43UK6300 has a good amount of ports and functional remote control. Furthermore, the television supports the LG magic remote that features a built-in mic for voice input.

Therefore, I will be rating the LG 43UK6300 an eight out of ten in this ports and connectivity features review section.

LG 43UK6300: Smart Features

Just like other LG smart televisions, the LG 43UK6300 comes with the webOS as its operating system. Moreover, the webOS platform offers a smooth lag-free interface that should be very easy to navigate.

Also, the LG 43UK6300’s webOS has a ribbon-style menu which makes it easy to access apps, services, and tools. Moreover, on the home page of the OS, you will an application bar at the bottom.

This app bar houses some pre-installed applications such as Netflix, Vudu, Amazon Prime Video, YouTube, and Sling TV. Aside from these pre-installed streaming apps, users also have access to over 140 free channels via the Channel Plus TV app.

Furthermore, users can also download more applications from the LG Content Store Unfortunately, the webOS platform features unwanted ads that users cannot opt-out from.

On a positive note, the webOS has a full web browser. Thus, whenever the LG 43UK6300 is connected to the internet, you will be able to browse freely.

That said, the LG 43UK6300 supports voice AIs such as Amazon Alexa and Google Assistant. Unfortunately, the television as well as its included remote control doesn’t feature a built-in mic.

However, because the television supports LG’s magic remote, you can purchase the remote for voice input. Also, you can buy an Amazon Echo Dot or a Google Nest speaker.

To end this smart features review section, I will be rating the LG 43UK6300 an eight out of ten.
