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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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"
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.
Like most IPS panel TVs, the contrast ratio is mediocre. This results in blacks that look grayish when viewed in the dark.
This TV doesn't have a local dimming feature. The video above is provided for reference only.
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.
Decent gray uniformity. There's vignetting at the corners and some dirty screen effect as well. Thankfully, uniformity is significantly better in dark scenes.
The viewing angles are okay, although it's a bit of a step down from the UM7300. It should be fine for a small to moderately-large room, but not for a large room or wide seating arrangements.
Mediocre black uniformity. 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.
Excellent reflection handling. It has a semi-gloss finish that diffuses light well, very similar to the UM7300.
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.

Upscaling of 720p content such as cable TV looks good and there are no visible artifacts.
The UN7300 uses an ADS (Advanced Dimension Switching) panel, which performs and behaves similarly to an IPS panel.
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.
The color volume is okay. It's an upgrade from the LG UM7300, but it still has difficulty displaying bright colors. Also, it doesn't display dark colors well due to its low contrast ratio.
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.
There are no signs of temporary image retention. The 0.05% deviation is caused by noise.
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.
Decent response time. There's some blur trail behind fast-moving objects and some overshoot that results in motion artifacts. There's visible duplication of the image due to the backlight's 120Hz flicker.
This TV uses PWM (Pulse-Width Modulation) to dim the backlight. It always flickers at 120Hz.
This TV doesn't have an optional black frame insertion.
This TV can interpolate lower frame rate content up to 60fps. It works okay most of the time, but there's duplication of the image due to the backlight's flicker and there are artifacts in more intense scenes.
To enable motion interpolation, set TruMotion to 'User' and adjust the De-Judder slider to '10'.
Due to the TV's slower response time, there's only a little bit of stutter in 24fps content. If the stuttering bothers you, enabling motion interpolation can help.
The UN7300 can only remove judder from 24p content. To do so, enable Real Cinema.
The UN7300 doesn't support any variable refresh rate technologies.
