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 sports an IPS panel that has a low contrast ratio and mediocre black uniformity, making it less ideal for watching movies or gaming in the dark. Its viewing angles are okay, it gets bright enough for use in most rooms, and it handles reflections exceptionally well. Response time is decent, but it lacks an optional black frame insertion feature and its backlight flicker causes visible image duplication. Input lag is extremely low; however, gamers looking for variable refresh rate support will have to look elsewhere. Although it supports HDR, the experience is rather unremarkable due to its low HDR peak brightness and lack of a wide color gamut.

Our Verdict

6.8 Mixed Usage

The 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 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 UN7300 is mediocre for watching movies. Like most IPS TVs, it has a low contrast ratio and mediocre black uniformity, making it less ideal for dark room viewing. Also, it doesn't have a local dimming feature. On the upside, it can remove judder from 24p content and it upscales lower resolution movies well.

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

The UN7300 is good for watching TV shows. It upscales lower resolution content from cable TV well, without any artifacts. Although its peak brightness is only mediocre, it has excellent reflection handling, which is great for watching daytime TV. 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 UN7300 is decent for watching sports. Its response time is decent, which results in only a bit of motion blur in fast-moving scenes. It doesn't get very bright; however, it handles reflections exceptionally well. It upscales lower resolution content well and there's minimal dirty screen effect. Viewing angles are just okay, so it's better suited for a small to medium-sized room.

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

The UN7300 is good for gaming. It has 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 VRR technologies. 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 UN7300 is sub-par for watching movies in HDR. It has a low contrast ratio, it doesn't have local dimming, and there's visible backlight bleed, which can be quite distracting in dark scenes. It can't display a wide color gamut and it can't make highlights stand out due to its low HDR peak brightness.

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

The UN7300 is okay for gaming in HDR. Although it performs well for gaming in general with its low input lag and decent response time, it isn't able to deliver a satisfying HDR experience due to its low HDR peak brightness and lack of a wide color gamut. Furthermore, 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 UN7300 is a good TV for use as a PC monitor. It has a low input lag, decent response time, and okay viewing angles, so the image won't degrade too much on the sides. It supports most resolutions and can display chroma 4:4:4 properly. 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.

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 UN7000 and the UN8500. We expect it to compete with the Samsung TU7000, the Sony X750H, and the Vizio V Series 2020.

Design

Design
Style
Curved No

The 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.

Footprint of the 55" model: 44.2" x 9.1"

Design
Back
Wall Mount VESA 300x300

The back of the TV is plain except for a fine texture that's etched into it. There's a plastic cable tie included in the box, but otherwise, there's not much in terms of cable management.

The TV is of medium thickness. It shouldn't stick out much when wall-mounted unless you use the back-facing inputs.

The build quality is decent. It's mostly plastic and there's some flex on the back panel; however, it feels sturdy overall and it doesn't wobble much.

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

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.

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

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.

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 aren't able to bring it any closer to our 6500K without affecting other calibration settings.

Although the UN7300 has a decent color gamut, it can't display a wide color gamut. The EOTF follows the PQ curve well; however, the roll-off starts very early. The 'Game' mode EOTF is nearly identical. If you find HDR content too dim, you can make it brighter by using the 'Vivid' Picture Mode and it results in this EOTF.

Decent gradient handling. There's banding in the darker shades of all colors and it's particularly visible in the grays. Enabling Smooth Gradation can help, although it had very little effect on our test pattern. Also, enabling Smooth Gradation can cause the loss of fine details in some scenes.
