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.

Our Verdict

7.6 Mixed Usage

The LG UM7300PUA is a good TV for most uses. It is best suited for a bright room, and is very good for watching sports in the afternoon or TV shows during the day. It doesn't look as good in a dark room, and although it supports HDR, this doesn't add much.

6.3 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.

8.1 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.

See our TV Shows recommendations
7.9 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.

See our Sports recommendations
8.4 Video Games

The LG UM7300 is a great TV for playing video games, especially for console gamers. It has outstanding low input lag, and an excellent response time. Unfortunately, it doesn't support any advanced gaming features, like FreeSync variable refresh rate technology.

See our Video Games recommendations
6.2 HDR Movies

The LG UM7300PUA delivers a mediocre HDR movie experience. It can't get very bright in HDR, and can't display a wide color gamut. It also doesn't have a local dimming feature, and can't display deep, uniform blacks in a dark room.

See our HDR Movies recommendations
7.7 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.

See our HDR Gaming recommendations
8.5 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.

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.

Design

Design
Style
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.

Design
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"

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.

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.

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.

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.

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.

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.
