This TV was replaced by the LG UN7300

The LG UM7300PUA is a good entry-level 4k TV that performs well in most uses. It has wide viewing angles that suit large rooms with wide seating area, and it has decent peak brightness and great reflection handling, making it a great choice for bright environments. Most gamers should be satisfied with its low input lag and fast response time, but if you need support for variable refresh rate, you'll have to look elsewhere. Sadly, like most IPS panels, it has a mediocre contrast ratio and it doesn't have a local dimming feature that can improve it. Although this TV supports HDR, it can't display a wide color gamut and its peak brightness in HDR mode isn't able to bring out highlights as intended. If you need a basic TV with good performance, though, the UM7300 is a good option.

Our Verdict

6.8 Mixed Usage

The LG UM7300PUA is a good TV for most uses. It's better suited for bright rooms, as its contrast ratio is mediocre and blacks tend to look like gray in the dark. It has exceptionally low input lag and response time to make it a great choice for gaming, and it has very little uniformity issues that can be distracting when watching sports. It can display HDR content, but performance is limited by its peak brightness and lack of wide color gamut support.

Pros
  • Outstanding low input lag.
  • Image remains accurate when viewed at an angle.
Cons
  • Can't produce deep, uniform blacks.
  • HDR doesn't add much.
6.0 Movies

Mediocre TV for watching movies in a dark room. It can't produce deep, uniform blacks. Motion looks decent overall, as it has an excellent response time, but there are duplications in motion from the backlight flicker. It can remove judder from true 24p sources, but not from movies played from a 60Hz source, like a cable box.

7.8 TV Shows

Great TV for watching TV shows during the day. It has decent peak brightness with SDR content and has excellent reflection handling, so you shouldn't have any issues in a decently-lit room. The image remains accurate when viewed at an angle. It has a great selection of apps, and most streaming channels are available.

7.5 Sports

This is a very good TV for watching most sports. It has wide viewing angles and excellent reflection handling, good for watching the big game with a group of friends. It has a fast response time, so there isn't much blur behind fast-moving objects, but there can be noticeable duplications in motion, which might bother some people.

6.9 Video Games

The LG UM7300 is a great TV for playing video games. It has an outstanding input lag at all supported resolutions, and its response time is equally exceptional, with very minimal blur in fast-moving scenes. Unfortunately, it doesn't support any variable refresh rate technology, but it does have an 'Auto Low Latency Mode', which saves you the trouble of having to switch picture mode every time you want to play.

5.7 HDR Movies

The LG UM7300PUA is mediocre for watching HDR movies. The TV supports HDR10, but not HDR10+ or Dolby Vision. Additionally, it can't display a wide color gamut and it can't get bright enough to bring out small specular highlights.

6.9 HDR Gaming

This is a good TV for HDR gaming, mainly due to the gaming performance, as HDR doesn't add much on this TV. It has outstanding low input lag, and an excellent response time. Unfortunately, it isn't as well-suited for late-night gaming, but the wide viewing angles make it a great choice for couch co-op gaming with some friends.

8.1 PC Monitor

Excellent TV for use as a PC monitor. It has outstanding low input lag, for a responsive desktop experience, and it supports all of the common 60Hz resolutions. It has a great response time, but the backlight flickers at 120Hz, which can bother some people with prolonged use. It can display proper chroma 4:4:4, so text looks good in any resolution.

Differences Between Sizes And Variants

We tested the 55" LG UM7300 (55UM7300). For the most part, we expect our review to be valid for the 43" model (43UM7300), 49" model (49UM7300), and the 65" (65UM7300) model.

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

Update 01/29/2020: LG Canada has confirmed that the 49" model uses an RGBW panel, similar to the UM6900 we've tested.

If someone comes across a different type of panel or if their LG UM7300 doesn't correspond to our review, let us know and we will update the review.

The 55UM7300 we reviewed was manufactured in March 2019.

Compared To Other TVs

Comparison picture

Top left: TCL S425(43S425). Bottom left: LG SM8600 (55SM8600). Middle: LG UM7300 (55UM7300). Top right: Vizio V Series 2019 (V505-G9). Bottom right: Samsung RU7100 (UN55RU7100).

The LG UM7300 is a good TV for most uses. It is considered a budget entry-level TV, which is why a lot of high-end features such as support for variable refresh rate and local dimming are noticeably missing. Compared to other IPS TVs, it performs well, but its viewing angles aren't as good. For other options, see our recommendations for the best TVs, the best smart TVs, and the best 4k TVs.

Samsung Q60/Q60R QLED
43" 49" 55" 65" 75" 82"

The Samsung Q60/Q60R QLED is a slightly better TV than the LG UM7300. The Samsung has much better black levels due to its VA panel, has a wider color gamut, handles motion better, and can get brighter. On the other hand, the LG uses an IPS panel which gives it much better viewing angles. The LG also feels slightly better-built, has better gray uniformity, handles reflections better, and has a slightly better-feeling remote.

Samsung TU7000
43" 50" 55" 58" 60" 65" 70" 75" 82" 85"

For most uses, the LG UM7300 is marginally better than the Samsung TU7000, but they use different panel types. The LG's IPS panel has a wider viewing angle, better reflection handling, and faster response time. On the other hand, the Samsung can produce deeper blacks due to its higher contrast ratio, and it has a black frame insertion feature to help reduce motion blur.

LG UN7300
43" 49" 50" 55" 65" 70" 75"

Compared to the LG UM7300, the LG UN7300 is a minor step down. The UN7300 has a lower SDR peak brightness, it has narrower viewing angles, and it has a slower response time. However, the UN7300 has a better color gamut and a slightly lower input lag.

LG NANO85 2020
49" 55" 65" 75"

The LG NANO85 is better than the LG UM7300. The NANO85 2020 has improved viewing angles, better out-of-the-box color accuracy, the ability to remove judder from any source, and it displays a wide color gamut for HDR content. The UM7300 has a direct backlight, so it has much better black uniformity and a bit better gray uniformity, but this could be due to panel differences.

Samsung TU8000
43" 50" 55" 65" 75" 85"

The LG UM7300 and the Samsung TU8000 are both decent TVs for mixed usage. The LG is a better option for TV shows and sports thanks to its higher peak brightness, slightly better motion handling, and better viewing angles due to its IPS panel. The brighter screen on the LG also makes it better for bright rooms, and its color gradient performance is significantly better. On the other hand, the Samsung has much deeper and more uniform blacks as it uses a VA panel, and it has a slightly lower input lag.

TCL 6 Series 2018
55" 65" 75"

The TCL R617 and the LG UM7300 use different panel technologies, each with their strengths and weaknesses. The R617 is better for watching movies or gaming in a dark room, as it has much better contrast, a full array local dimming feature, and an optional black frame insertion feature. The UM7300, on the other hand, is better suited for watching sports or TV shows in a bright room with wide seating.

Samsung Q50/Q50R QLED
32"

The LG UM7300 and the Samsung Q50/Q50R QLED use different panel types, each with their own strengths and weaknesses. The Q50R is better-suited for use in a dark room, as it has much better contrast. The UM7300 doesn't look as good in a dark room, as blacks appear gray, but the image remains accurate when viewed at an angle. Whereas the Q50R is only available in a 32" size, the UM7300 is available in sizes ranging from 43" to 65".

LG UM6900
43" 49" 55" 60" 65" 70" 75"

The LG UM7300 is much better than the LG UM6900. The UM7300 is much brighter, has better black uniformity, and better reflection handling. The UM7300 uses an RGB IPS panel, whereas the UM6900 uses a less-accurate RGBW pixel structure. The UM7300 also comes with a more advanced remote and has voice control capabilities.

Sony X850G
55" 65" 75" 85"

The Sony X850G is a bit better than the LG UM7300. The X850G is a lot brighter but has worse black uniformity. The backlight of the X850G is flicker-free, and it has an optional black frame insertion feature. Other than that, these two TVs perform almost identically.

Vizio M Series Quantum 2019
55" 65"

The Vizio M Series Quantum 2019 is a much better TV than the LG UM7300. The Vizio has much deeper blacks, higher peak brightness, much better black uniformity, a much wider color gamut, and better motion handling. On the other hand, the LG has much wider viewing angles thanks to its IPS panel, a much better smart interface, and a larger and more robust remote control.

Hisense H8F
50" 55" 65"

The LG UM7300 and the Hisense H8F use different panel types, each with their strengths and weaknesses. The H8F is better for watching movies or playing games in a dark room, but has worse motion handling. The LG looks better in a bright room, especially if you have a wide seating area, so it's a better choice for use as a PC monitor or for watching sports.

Sony X800G
43" 49" 55" 65" 75"

The LG UM7300 is somewhat better than the Sony X800G. The LG can handle reflections better, which is great if your room has a lot of lights. The LG also has an extremely low input lag that's great for gaming. The Sony, on the other hand, is flicker-free, which might be important to some people.

LG SM8600
49" 55" 65" 75"

The LG SM8600 is a little better than the LG UM7300. The SM8600 has a faster response time, which is great for sports, and a wide color gamut, which is great for HDR. The UM7300 can get brighter, which is great for watching TV in a brighter room, and its Automatic Brightness Limiter doesn't change the brightness according to the scene.

Vizio V Series 2019
40" 43" 43" 50" 55" 55" 60" 65" 65" 70" 75"

The Vizio V Series 2019 and the LG UM7300 have different panel types, each with their strengths and weaknesses. The V Series has a VA panel, which looks better in a dark room, as it delivers deep, uniform blacks. The UM7300 has an IPS panel, which doesn't look as good in a dark room, but the image remains accurate when viewed at an angle.

LG UK7700
55" 65"

The LG UM7300 is slightly better than the LG UK7700. The UM7300 is a bit brighter and has better black uniformity. Unlike the UM7300, the UK7700 has a local dimming feature, but it isn't very effective anyway. The UK7700 has a slightly better design, with a full-metal back, and it has an additional HDMI input.

LG UK6300
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.

TCL 4 Series 2019
43" 49" 50" 55" 65" 75"

The LG UM7300 is a better TV than the TCL 4 Series 2019 for most uses. The LG uses an IPS panel, which gives it better viewing angles but worse black levels. The LG can get a lot brighter, has better gray uniformity, and more accurate colors. On the other hand, the TCL has a slightly wider color gamut and better gradient handling.

Samsung Q80/Q80R QLED
55" 65" 75" 82"

The Samsung Q80/Q80R QLED is a much better TV than the LG UM7300. The Q80R looks more premium, has much better contrast and higher peak brightness, resulting in more uniform blacks and better reflection handling. It also as much more accurate colors out-of-the-box, and a much wider color gamut, making it a better choice for HDR content. While the LG has slightly lower input lag, the Samsung has better motion handling.

Samsung Q70/Q70R QLED
49" 55" 65" 75" 82" 85"

The Samsung Q70/Q70R QLED is a much better TV than the LG UM7300. The Q70R looks and feel much better built, has much deeper blacks thanks to its higher contrast ratio and local dimming feature, and can get much brighter which allows HDR content to really pop. On the other hand, the LG uses an IPS panel which gives it much wider viewing angles, and it has a more robust remote.

Samsung RU8000
49" 55" 65" 75" 82"

The Samsung RU8000 and the LG UM7300 use different panel technologies, each with advantages and disadvantages. The Samsung is better-suited for dark room viewing thanks to the high contrast ratio of its VA panel, and it has extra gaming features like VRR support. The Samsung also has a faster response time and delivers crisper motion. The LG, on the other hand, is better suited for a larger room with wide seating arrangements as the image remains accurate when viewed at an angle.

Samsung RU7300
55" 65"

The Samsung RU7300 and the LG UM7300 are similar, but they have different panel types, each with their advantages and disadvantages. The LG has an IPS panel which maintains an accurate image when viewed at an angle but can't deliver deep uniform blacks in a dark room. The Samsung is curved TV and has a VA panel that looks much better in a dark room, but only when sitting directly in front as the image loses accuracy when viewed at an angle.

Samsung RU7100
43" 50" 55" 58" 65" 75"

The Samsung RU7100 and the LG UM7300 are similar, but they use different panel types, each with their strengths and weaknesses. The LG UM7300 has an IPS panel, which remains accurate when viewed at an angle, but can't produce deep, uniform blacks. The Samsung RU7100 has a VA panel and looks much better in a dark room, but only when sitting directly in front, as the image degrades rapidly when viewed at an angle.

Samsung NU7100
40" 43" 50" 55" 58" 65" 75"

The Samsung NU7100 and the LG UM7300 use different panels, and the best one depends on your usage. The NU7100 is better-suited for dark-room viewing, sitting directly in front. The LG UM7300 is better suited for watching with the lights on and is a better choice for a wide seating area. The UM7300 has better motion handling overall, with a much faster response time, which is better for gaming or other 60p content.

Samsung NU6900
43" 50" 55" 65" 75"

The LG UM7300 and the Samsung NU6900 has different panel technologies, each with advantages and disadvantages. The NU6900 can deliver deep blacks in a dark room thanks to its high native contrast ratio, whereas the UM7300 is a better choice if your room has a wide seating arrangement. Also, the LG can handle reflections better and can remover judder in most cases, whereas the Samsung can't remove judder at all.

The 55UM7300PUA has a decent peak brightness, good enough for most decently-lit rooms, and there's very little variation in brightness when displaying different content.

Peak brightness was measured with the 'ISF Expert (Dark Room)' Picture Mode, which is the most accurate. Different picture modes and color temperatures can produce slightly different results.

If image accuracy isn't as important to you, the 'Vivid' Picture Mode delivers a slightly brighter image, reaching a peak of 402 cd/m² with a 10% window.

The LG UM7300PUA has a decent color gamut, but it can't display a wide color gamut. The 'Expert (Dark Room)' EOTF (above) follows the target PQ curve almost perfectly until it rolls off near the TV's peak brightness. The Game mode EOTF is almost identical.

If you find HDR too dim, unfortunately, there isn't much you can do on this TV. Setting Dynamic Contrast to 'High' increases the brightness of bright scenes, and helps a bit in extremely dark scenes. See our full recommendation here.

Disappointing color volume. This TV can't produce very bright colors, and can't produce dark saturated colors, due to the mediocre contrast ratio. These results are better than the UK6300 this TV replaces, but not as good as the UK7700.

Good gradient performance overall, but there is noticeable banding in almost all areas. If banding bothers you, the Smooth Gradation feature can remove banding, but also causes a loss of some fine details in some scenes.

The UM7300 has an optional motion interpolation feature, but it can only interpolate up to 60 fps. In fast-moving scenes, it can struggle a bit and stop interpolating, causing the picture to appear jerky due to the sudden change in refresh rate.

The LG UM7300 has a disappointing frequency response. The low-frequency extension (LFE) is at about 120Hz, which is bad, and results in a bass that can't produce and thump or rumble, and doesn't have much body or punch. Above the LFE the frequency response is well balanced, which results in clear dialogue. Although this TV is loud enough for quiet environments, if you have a lot of ambient noise it might not be enough.
