The LG UN7300 is an okay budget 4k TV. It's a follow-up of 2019's LG UM7300, and it offers largely similar performance and features. Like its predecessor, it has an IPS panel with a low contrast ratio and mediocre black uniformity, which isn't ideal for watching movies or gaming in the dark. Its viewing angles are just okay, causing a slight loss in image accuracy when viewed from the side. It has excellent reflection handling, but visibility can still be an issue in well-lit environments because it doesn't get bright enough to overcome intense glare. It has a decent response time and its input lag is low enough to satisfy most gamers; however, those looking for advanced gaming features like variable refresh rate technology will have to look elsewhere. Lastly, it can't display a wide color gamut and doesn't get noticeably brighter in HDR, so HDR content doesn't look much different from SDR.

Our Verdict

6.8 Mixed Usage

The LG UN7300 is okay for most uses. It performs well enough for watching TV shows or for gaming; however, its low contrast ratio, mediocre black uniformity, and lack of local dimming make it a poor choice for watching movies. Also, it delivers a sub-par HDR experience due to its low HDR peak brightness and lack of a wide color gamut. It has a decent response time and low input lag, but sadly, it doesn't support any variable refresh rate technologies to reduce screen tearing when gaming.

Pros
  • Excellent reflection handling.
Cons
  • Low contrast ratio.
  • Mediocre SDR peak brightness.
6.0 Movies

The LG UN7300 is mediocre for watching movies. It isn't well-suited for dark rooms, as it has a low contrast ratio and mediocre black uniformity, resulting in blacks that look grayish. Also, it doesn't have a local dimming feature to improve black level. On the bright side, it doesn't stutter much in low frame rate content such as movies, and it can remove judder from 24p sources and native apps.

Pros
  • Can remove judder from 24p content.
Cons
  • Low contrast ratio.
  • No local dimming.
7.6 TV Shows

The LG UN7300 is good for watching TV shows. It upscales lower resolution content from cable TV well, without any artifacts. It has excellent reflection handling, but it doesn't get very bright and might struggle to overcome intense glare in well-lit environments. Its viewing angles are just okay, which means that the image degrades a bit when viewed from the side.

Pros
  • Excellent reflection handling.
  • Decent gray uniformity.
Cons
  • Low contrast ratio.
  • Mediocre SDR peak brightness.
7.3 Sports

The LG UN7300 is satisfactory for watching sports. It has a decent response time that results in only a small amount of motion blur in fast-moving scenes, but it doesn't have a Black Frame Insertion feature to improve clarity. Unfortunately, even though it has excellent reflection handling, it doesn't get very bright and might not be able to overcome intense glare. The viewing angles on its IPS panel are just okay, making it more suitable for a small-to-medium-sized room. It upscales lower-resolution content like cable sports well and has no risk of permanent burn-in.

Pros
  • Excellent reflection handling.
  • Decent gray uniformity.
  • Decent response time.
Cons
  • Low contrast ratio.
  • Mediocre SDR peak brightness.
7.5 Video Games

The LG UN7300 is good for gaming. It has a decent response time, so there's only a little bit of motion blur behind fast-moving objects. Input lag is extremely low, but unfortunately, the refresh rate is limited to 60Hz, and it doesn't support any variable refresh rate technology to reduce screen tearing. Also, it has a low contrast ratio and mediocre black uniformity, making it a poor choice for dark rooms.

Pros
  • Low input lag.
  • Excellent reflection handling.
  • Decent response time.
Cons
  • Low contrast ratio.
  • No FreeSync support.
5.8 HDR Movies

The LG UN7300 is sub-par for watching movies in HDR. It has a low contrast ratio and lacks local dimming, so blacks look more like gray when viewed in the dark. There's visible backlight bleed, which can be quite distracting in dark scenes; however, uniformity can vary between units. Sadly, it can't display a wide color gamut and doesn't get bright enough to make highlights stand out the way they should. On the upside, there's very little stutter in lower frame rate content, and it can remove judder from 24p sources and native apps.

Pros
  • Can remove judder from 24p content.
Cons
  • Low contrast ratio.
  • Sub-par HDR peak brightness.
  • No local dimming.
6.8 HDR Gaming

The LG UN7300 is okay for gaming in HDR. It performs well for gaming due to its low input lag and decent response time, but it doesn't support any variable refresh rate technology to reduce screen tearing. It can't deliver a satisfying HDR experience because it can't display a wide color gamut and doesn't get very bright. Also, the contrast ratio is low, and there's no local dimming.

Pros
  • Low input lag.
  • Decent response time.
Cons
  • Low contrast ratio.
  • Sub-par HDR peak brightness.
  • No FreeSync support.
  • No local dimming.
7.8 PC Monitor

The LG UN7300 is a good TV for use as a PC monitor. It has a low input lag and decent response time, delivering a responsive desktop experience. The viewing angles are okay, so the image doesn't degrade too much at the edges if you sit up close. It supports most resolutions and can display chroma 4:4:4 properly for optimal text clarity. Also, there's no risk of permanent burn-in.

Pros
  • Low input lag.
  • Excellent reflection handling.
  • Supports chroma 4:4:4.
Cons
  • Low contrast ratio.
  • 6.8 Mixed Usage

Market Context

The LG UN7300 is a replacement for 2019's UM7300, and it's one of LG's budget 4k TV for 2020, sitting between the LG UN7000 and the LG UN8500. We expect it to compete with the Samsung TU7000, the Sony X750H, and the Vizio V Series 2020.

The LG UN7300's design is decent and almost identical to the LG UM7300. It's simple but it has pretty thick bezels that protrude from the screen. The stand is slightly lower-set than its predecessor and the back of the TV is plain except for a fine texture.

Design
Stand

The feet are set as almost as wide as the TV itself, so it requires a large table. It supports the TV well and there's only a little bit of wobble.

Like most IPS panel TVs, the contrast ratio is mediocre. This results in blacks that look grayish when viewed in the dark. Note that the contrast ratio can vary between units.

There appear to be two versions of the UN7300 with the same model code. The one we tested has an IPS panel and is identified as a "Real 4k IPS" on the box. It's also possible to find a VA version of it, which is identified by the text "Real 4k Display" on the box. We expect the VA version to have much better contrast, but worse viewing angles.

Mediocre SDR peak brightness. It's better suited for a dark to moderately-lit room, as it can't get bright enough to overcome glare in a well-lit environment. The brightness is consistent across different content except for a slight dimming of the 2% window caused by the TV's CE dimming (frame dimming).

We measured the SDR peak brightness after calibration, using the 'Expert Dark' Picture Mode and with Brightness set to maximum. We disabled all other image processing.

If you don't mind losing image accuracy, you can get a brighter image by setting the Picture Mode to 'Vivid' and Dynamic Contrast Enhancer to 'Medium'. These settings allow us to achieve 347 cd/m² in the 10% window.

Sub-par HDR peak brightness. Although the brightness is consistent, it isn't nearly enough to deliver a satisfying HDR experience, so HDR content won't look much different from SDR. The 2% window is dimmer due to frame dimming. If you want a TV that gets brighter in HDR, look into the LG UN7000.

We measured the HDR peak brightness before calibration, using the 'Cinema' Picture Mode, and with Brightness and Contrast set to maximum.

If you want to make HDR content brighter and don't mind losing accuracy, set the Picture Mode to 'HDR Vivid' and Dynamic Contrast Enhancer to 'Medium'. These settings allowed us to achieve 408 cd/m² in the 10% window.

Black uniformity is mediocre; however, this can vary between individual units. There's some clouding throughout the screen, and the backlight bleed at the bottom left corner is visible in dark scenes, even in normal content.

If you want a TV with better black uniformity, check out the Samsung TU7000.

Out of the box, the color accuracy is okay. There are inaccuracies with several colors and white balance is off. The color temperature is colder than our 6500K target, which results in a blueish tint. Darker scenes are mostly displayed at the correct brightness, but brighter scenes are over-brightened. Note that color accuracy can vary between units.

After calibration, the color accuracy is outstanding. White balance and gamma are nearly perfect, and the remaining inaccuracies shouldn't be noticeable to the naked eye. Unfortunately, the color temperature is still on the colder side, and we weren't able to bring it any closer to our 6500K without affecting other calibration settings.
