The LG UM7300PUA is a good 4k TV with a wide viewing angle, excellent low input lag, and an excellent response time. It has decent peak brightness in SDR, and it has excellent reflection handling, making it a great choice for a wide seating area in a brighter room. Unfortunately, like the majority of IPS TVs, it doesn't look as good in a dark room, as it can't produce deep, uniform blacks. It also has very limited HDR support and doesn't support any dynamic HDR formats, like HDR10+ or Dolby Vision.

Market Context

The UM7300 is LG's basic 4k model for 2019 for U.S. markets. It replaces the 2018 model UK6570. There is a 2019 UM6300, but this is now a 1080p model. The main competitors for this model are the Sony X800G, the Samsung RU7100, and the Vizio V Series 2019.

7.0

Design

Curved : No

The LG UM7300 has a decent design. It looks very similar to last year's UK6300 and UK7700. The legs are very close to the sides of the TV, so it needs a large stand to support it if it isn't wall mounted. The stand supports the TV well, but does wobble a bit if nudged or if your floor isn't solid. It has decent build quality, and there are no obvious signs of concern, but it doesn't have the metal back of the UK7700. There is no cable management.

Stand

The stand supports the TV well, allowing only minimal wobble when nudged. Unfortunately, the stand is nearly the full width of the TV, so you'll need a large TV stand if it isn't wall-mounted.

Footprint of the 55" model: 44.5" x 9.1"

Back
Wall Mount : VESA 300x300

The back of the TV is very plain. Some of the connectors face directly out the back and may be difficult to access if wall-mounted. There is no integrated cable management.

Borders
Borders : 0.63" (1.6 cm)

The borders are thin and not very distracting.

Thickness
Max Thickness : 3.46" (8.8 cm)

The LG UM7300PUA is slightly thicker than the UK6300. It sticks out quite a bit when wall-mounted.

7.0 Build Quality

The LG 55UM7300PUA has decent build quality. It wobbles a bit less than the UK6300, and has a nicer frame, but doesn't have the metal back found on the UK7700.

7.2

Picture Quality

The LG UM7300PUA delivers decent overall picture quality. Like most IPS TVs, it has a mediocre contrast ratio, and isn't as well-suited for dark room viewing. This model doesn't have a local dimming feature, but has decent black uniformity. The UM7300 has decent peak brightness in SDR, but in HDR it can't get bright enough for small highlights to really stand out. It has decent viewing angles and excellent reflection handling. Unlike the UK6300, this TV doesn't use an RGBW pixel structure, and there is no subpixel dithering, which is great.

6.2 Contrast
Native Contrast
:
1105 : 1
Contrast with local dimming

Like most IPS TVs, the LG UM7300 has a mediocre contrast ratio, very similar to the UK6300. Blacks look slightly grayish in a dark room. Unfortunately, this TV lacks a local dimming feature to improve dark room performance.

The 50" model is expected to have a VA panel, and will have a much better contrast ratio.

Decent peak brightness, good enough for most decently-lit rooms. The 55UM7300PUA is significantly brighter than the UK6300 and a bit brighter than the UK7700, which is great. There is very little variation in brightness with different content, which is great.

We measured the peak brightness with the 'ISF Expert (Dark Room)' Picture Mode, as it 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.

Mediocre HDR peak brightness, too dim to show off small specular highlights in some scenes. It is slightly brighter than the UK6300 and UK7700.

We measured the HDR peak brightness with the 'Cinema' Picture Mode before calibrating. 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 about 410 cd/m² with a 10% window.

The LG UM7300PUA has a decent viewing angle, but it isn't as good as most IPS TVs. Colors don't shift very much at an angle, but they wash out at moderate angles. The black levels remain relatively flat at moderate angles, but at wider angles they increase, causing the image to appear washed out.

The 50" model is expected to have a VA panel, and will have worse viewing angles.

6.7 Black Uniformity

Decent black uniformity, but there is noticeable backlight bleed, which is typical for IPS TVs. Unfortunately, there is no local dimming feature, which could improve black uniformity.

The 50" model is expected to have a VA panel, and will have a much better contrast ratio, and likely has better black uniformity.

After calibration, the UM7300 has excellent accuracy. The white balance is almost perfect, with only a slight inaccuracy in pure whites. Gamma follows our target of 2.2 almost perfectly. There are still a few color inaccuracies, especially in highly saturated blues, but most people won't notice it.

You can see our recommended settings here.

8.0 480p Input

Older content, like DVDs, looks great, with no obvious issues or upscaling artifacts.

8.0 720p Input

720p content, including most cable TV stations, looks great, with no obvious issues.

9.0 1080p Input

1080p content, like Blu-rays and older consoles, looks almost as good as native 4k content.

10 4k Input

Unlike the UK6300, the LG UM7300 does not use an RGBW pixel structure, and 4k content is displayed with no issues.

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.

7.2

Motion

The LG UM7300 has decent motion handling. It has a great response time, producing clear motion that has only a short blur trail behind it. The backlight flickers at 120Hz at any setting, which may bother some people, and causes duplications in moving objects. It doesn't have an optional black frame insertion feature, and doesn't support any of the variable refresh rate technologies.

8.6 Response Time
80% Response Time
:
5.6 ms
100% Response Time
:
12.4 ms

The UM7300 has an excellent response time, with very little overshoot, which is great. It is a bit faster than UK7700, and quite a bit faster than the UK6300.

4.0 Flicker-Free

No
PWM Dimming Frequency
:
120 Hz

The backlight flickers at 120Hz regardless of Backlight setting, which may bother some people. This low flicker frequency does help to clear up motion a bit, but causes noticeable duplications, as seen in our Motion Blur photo.

The LG UM7300PUA does not have an optional Black Frame Insertion feature. The backlight flickers at 120Hz in any mode, which does help clear up motion, but causes some noticeable duplications in motion, as seen in our Motion Blur photo.

7.0 Motion Interpolation
Motion Interpolation (30 fps)
:
Yes
Motion Interpolation (60 fps)
:
No

There is an optional motion interpolation feature, but as it is a 60Hz panel, it can only interpolate up to 60 fps. Like the majority of TVs, the UM7300 does its best to interpolate fast action, but when it can't keep up it stops interpolating, which can be distracting due to the sudden change in refresh rate.

Learn more about motion interpolation, and how to enable it on the UM7300, here.

7.2 Stutter
Frame Hold Time @ 24 fps
:
29.3 ms
Frame Hold Time @ 60 fps
:
4.3 ms

Due to the fast response time, low frame rate content, like movies, does appear to stutter at times. This is especially noticeable in wide panning shots. You can reduce the effects of stutter by enabling motion interpolation.

Inputs

The LG UM7300 has outstanding low input lag, and it supports all of the common 60Hz input formats. It can also display chroma 4:4:4 properly with any resolution, but only in 'PC' mode. It has a decent selection of inputs, but has fewer HDMI inputs than more expensive models. Unfortunately, this model only supports HDR10, and does not support any dynamic HDR formats, like HDR10+ or Dolby Vision.

Sound Quality

The LG UM7300PUA has mediocre sound. It can't get very loud, and the bass can't produce any thump or rumble, and has very little body. It has a well-balanced sound for clear dialog, but it lacks some airiness. For a better sound, a dedicated speaker setup or soundbars is recommended (see our recommendations for the best soundbars).
