The LG UK6300 is a decent RGBW IPS TV with wide viewing angles, so it remains accurate when viewed at an angle. It also has low input lag so feels responsive. Unfortunately, when viewed in a dark room, blacks appear gray due to the low native contrast ratio, but when viewed in a bright room, this isn't noticeable. The out of the ordinary "RGBW" pixel structure also can cause smaller details and straight lines to lose sharpness, especially when used as a PC monitor.

Our Verdict

6.4 Mixed Usage

The LG UK6300 is a decent TV for mixed usage. It has decent picture quality and a passable viewing angle, but it isn't able to overcome glare in a bright room and has poor dark room performance. It has a good smart interface and extraordinarily low input lag.

Pros
  • Feels responsive with low input lag
  • Short blur trail
Cons
  • Blacks appear gray in a dark room
  • Less accurate RGBW pixel structure
5.5 Movies

Not a good choice for movie lovers. It doesn't get very bright. Blacks aren't truly black and it has poor uniformity, so letterbox bars look cloudy. Subtitles don't look good due to the lack of a local dimming feature.

7.3 TV Shows

The LG UK6300 is good for watching TV Shows. Low frame rate content looks great. The TV isn't bright enough to be used in a bright room as it can't overcome glare, so daytime viewing is somewhat compromised. It has a good smart interface with a wide assortment of apps available for watching streaming TV.

6.9 Sports

Decent TV for watching sports. There is some dirty screen effect visible in the center of the screen, but it shouldn't be very noticeable. It has a good viewing angle great for game day parties, although it isn't very bright which might be an issue for daytime games in a bright living room. It has a good response time, so fast-paced sports don't have much motion trail.

7.0 Video Games

Good TV for video games, mainly due to the excellent low input lag when game mode is used. The TV has a good response time, so there is very little motion blur. It has decent picture quality, but some games suffer from the low contrast ratio.

5.3 HDR Movies

Disappointing HDR Movie experience. It has a poor native contrast and no local dimming feature. It doesn't support a wide color gamut and can't produce deep dark colors. There is almost no advantage to watching in HDR on the UK6300.

6.4 HDR Gaming

Decent HDR Gaming performance. Exceptional low input lag, and the response time is good, so there is very little motion trail. The mediocre peak brightness and lack of a wide color gamut means the HDR effect is not very noticeable.

7.6 PC Monitor

Decent PC monitor. It has excellent low input lag and a good viewing angle. The response time is good so there is little motion trail. The less accurate RGBW pixel structure means that text appears jagged as seen on the UH6500, even though the TV supports Chroma 4:4:4.

Test Results

Design
6.5
Design
Style
Curved No

The design of the 2018 UK6300 LED TV is very basic. It is a very functional design with no serious deficiencies, but it won't be the center of attention in a room. Some of the rear-facing inputs may be difficult to access when wall mounted, and if a component connection is required it is impossible to mount the TV flush to the wall. There is no cable management.

Design
Stand

The stand is almost the full width of the TV and is identical to the UJ6300 from last year. It is made of plastic and supports the TV well.

Footprint of the 55" TV stand: 33.3" x 8.6"

Design
Back
Wall Mount VESA 200x200

The back of the TV is very basic. There is no cable management. It is nearly identical to the UJ6300 from last year. Some of the inputs face out the back of the TV, which may be difficult to access if wall mounted.

Update 03/04/2019: The VESA mount was incorrectly listed as 400x400, it is actually 200x200 on the 43" model.

Design

Mediocre native contrast ratio. Blacks are not truly black, and dark room viewing is less than ideal, especially taking into account the black uniformity results.

The contrast ratio is slightly worse than last year's UJ6300.

Note: The 50" model available in some areas has a VA panel, which we expect to have a higher native contrast ratio.

Mediocre peak real scene with the more accurate Expert (Dark Room) picture mode. There is almost no variation depending on content.

For a brighter room, the Standard picture mode with our recommended settings and a W30 color temperature is better, peak brightness is 286 cd/m². In Vivid mode with the default settings, the UK6300 is much brighter at 364 cd/m², although a lot of color accuracy is lost in that mode.

It is a bit brighter than the UJ6300, especially when the other picture modes are used.

Mediocre HDR peak brightness. The LG UK6300 is not bright enough to overcome glare in a bright room, but due to the poor black uniformity, it is not well suited to a very dark room. Like with SDR content, small highlights in some scenes do not really pop, brightness is very similar regardless of content.

Standard color gamut, only good enough for SDR. See our recommended settings for the most accurate colors here.

The Expert (Dark Room) EOTF follows our curve perfectly, and the brightness rolls off gently as the TV approaches its peak brightness.

The PC and Game EOTF curves follow the input closely but are under the curve a bit. In these modes, the brightness rolls off gently at the peak brightness of the TV, so there is less clipping.

Update 06/29/2018: The DCI P3 xy and DCI P3 uv results were swapped when entering the data. This has now been fixed, and the score and performance are unchanged.

The TV uses PWM to dim the backlight, and there is flicker at all backlight levels. This flicker helps to clear up motion a little, but results in duplications in fast moving objects.

Extraordinary low input lag, as long as the 'Game' Picture Mode is selected. For use as a PC Monitor, it is recommended to set the input label to 'PC', and use the'Game' Picture Mode for the lowest input lag possible.

Chroma 4:4:4 only works properly when the input label is set to 'PC' with RGB color; it doesn't display correctly with YCbCr.

Most of the common input resolutions are supported with issue. Like most LG TVs, the input label has to be set to 'PC' for chroma 4:4:4 support. For 4:4:4 to work properly, RGB colors must be used. The less accurate RGBW pixel structure causes artifacts when used as a PC Monitor.

For 4k 60Hz, HDMI Ultra HD Deep Color must be enabled in the Additional Settings menu for the input used.

4k HDR does not work properly when in PC mode, colors appear washed out.

The LG UK6300 has a below-average frequency response performance. LFE (low-frequency extension) is at 100Hz, which is sub-par. This means that this TV will have a full and warm sound, but not a lot body or punch, and no thump or rumble to its bass either. The response above the LFE is well-balanced for the most part, which results in clear dialogs but they may lack some airiness. Also, this TV doesn't get very loud and produces considerable pumping and compression artifacts under heavy loads. Additionally, since this TV doesn't have a room correction system, it wasn't able to remove the mode of our test room which occur around 200Hz.

Differences Between Sizes And Variants

We tested the 43" (43UK6300PUE). For the most part, we expect our review to be valid for the 49" (49UK6300), 55" (55UK6300) and 65" (65UK6300).

The UK6570 has been released in 70", 75" and 86" sizes. We haven't tested them and don't know how they perform or if they are the same panel as the UK6300. The 86" has a 120 Hz native refresh rate.

There is a 50" variant with a VA panel available in some areas. We expect this model to have a much better native contrast and black uniformity, but the viewing angle won't be as good.

If someone comes across a different type of panel or if their LG UK6300 doesn't correspond to our review, let us know and we will update the review.

Update 12/05/2018: LG has recently released the UK6090 (UK6090PUA), which appears to be a minor variant of the UK6300. They appear to perform similarly, but there may be some minor differences we are unaware of.

Compared To Other TVs

The LG UK6300 is a very basic entry level 4k LED TV, but it doesn't offer great value compared to the competition. There will almost always be something better for a similar price. See our recommendations for the best budget TVs and the best TVs under $500.

Samsung NU8000
49" 55" 65" 75" 82"

These two TVs have different panel types. For a room with a wide seating arrangement, the LG UK6300 might be a better choice if you'll often be watching TV from the side. However, the Samsung NU8000 is a much better choice if you'll be watching from straight in front. It can get much brighter to fight glare and can also display deeper blacks thanks to its high native contrast ratio. The NU8000 has better gray uniformity and faster response time which makes it great for watching sports. Finally, the NU8000 has FreeSync support and low input lag with motion interpolation, which is great if you are a gamer.

LG UM7300
43" 49" 50" 55" 65"

The LG UM7300 is much better than the LG UK6300. The UM7300 is much brighter than the UK6300, has better black uniformity, and has a faster response time. The UK6300 uses a less accurate RGBW pixel structure, which causes some noticeable artifacts with 4k content, whereas the UM7300 has a standard RGB pixel structure.
