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.
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.
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.
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.
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.
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.
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.
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.
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.
The LG UM7300 has a decent design. It's fairly minimalist, with thin bezels and wide-set feet. The stand supports the TV well, but there's some wobble.
The stand supports the TV well, though it wobbles a bit when nudged. The feet are wide-set, 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's no integrated cable management.
The LG UM7300PUA is slightly thicker than the UK6300. It sticks out quite a bit when wall-mounted, especially if you use the back-facing inputs.
The LG UM7300 has a mediocre contrast ratio, which is expected of most IPS panels. Blacks will appear grayish when viewed in the dark, and unfortunately, there's no 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.
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.
This TV doesn't have a local dimming feature. The above video is for reference only.
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 UM7300 has good gray uniformity. There's some vignetting at all corners of the screen, but only slight dirty screen effect, which is great.
Decent black uniformity, but there is noticeable backlight bleed, which is typical for IPS TVs.
The 50" model is expected to have a VA panel and will have a much better contrast ratio, and likely has better black uniformity.
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 they increase at wider angles, causing the image to appear washed out.
The 50" model is expected to have a VA panel, and will have worse viewing angles.
The LG 55UM7300PUA has excellent reflection handling, very similar to the LG UK7700. The semi-gloss finish diffuses reflections across the screen, without the purple tint seen on high-end TVs.
Out of the box, the UM7300 has decent color accuracy, but gamma is too high for the most part, causing most scenes to appear darker than they should.
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.

Older content, like DVDs, looks great, with no obvious issues or upscaling artifacts.
720p content, including most cable TV stations, looks great, with no obvious issues.
1080p content, like Blu-rays and older consoles, looks almost as good as native 4k content.
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.
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 TV shows some minor signs of temporary image retention, but it disappears almost immediately.
Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent as the IPS panel in our long-term test appear immune.
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 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.
Learn more about motion interpolation, and how to enable it on the UM7300, here.
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.
The LG UM7300 can remove judder from true 24p sources, like a Blu-ray player or the native apps, but can't remove judder from sources that output at 60Hz, like a cable box.
See here for our recommended settings for judder removal.
